[android-developers] Android Nougat / 7.0 issues with utilizing IIS https web services

[Simon Marcinkowski]

Hello there,
I have an app which connects perfectly with our IIS services on all SDK 
versions <24. 
When installed on Pixel phone, it doesn't want to connect with same 
services. I checked changes to Android N related with network security and 
it looks that those changes affects network behavior. 
I followed instructions on google here  
but 
I'm not 100% sure it works for me. So the first question is: 
1. If correctly implemented network_security_config.xml with certs issued 
for my website, do I need any code changes when using ksoap2 or it will 
just work?
Version used in current app is 
app/libs/ksoap2-android-assembly-3.0.0-RC.2-jar-with-dependencies.jar I 
know is old but works perfectly so far. 
2. Are there any changes in current versions of ksoap2 which possibly 
affects network connection on Pixel phone? Should I update it?

Now I have this error javax.net.ssl.SSLHandshakeException: Connection 
closed by peer . 
I'm not sure how properly embed cert in my app. I'm using GoDaddy certs and 
there are only *.cer certs available and Google mention about PEM and DER 
formats. 
3. If anybody could point me how to properly embed certs, that would be 
great. I found https://blog.sagaoftherealms.net/?p=578 procedure to embed 
certs but on linux and I'm on windows platform.
Just a while ago I exported certs using Chrome export cert (DER encoded 
binary X.509 cer) when browsing our page, embedded in app under res/raw but 
I got this message Caused by: 
android.security.net.config.XmlConfigSource$ParserException: Unknown 
certificates src. Should be one of system|user|@resourceVal at: Binary XML 
file line #13 so I belive it is in the wrong format.
4. Is it a big difference when I refer to sources using @ (at) char at the 
beginning? For some reason when I use @ system can't recognize this 
resource, but when I remove it, it works.

I would be very appreciated for any help. I'm not Java Android developer 
but I need to fix this quickly,
Thanks in advance! :)

[android-developers] ScrollView not erasing all of top line

[Simon Giddings]

I have a custom view embedded within a ScrollView which displays music 
scores.
When I scroll the view, after a time, parts of the top row are not erased.
Here is an example which illustrates the problem -



Here is another closeup view



I have no code which does any erasing.

Is this a known problem ?

Does anyone know of a solution or workaround ?

[android-developers] Re: App uninstall doesn't remove SQL database

['Simon Ho' via Android Developers]

This is getting stranger. This only seems to happen on Windows. This is the 
process I tried:

1. Delete/uninstall the app from the phone
2. Run app from android studio on Windows. Problem: database still exists 
and app sees all old data (even though I uninstalled the app)
3. Uninstall app
4. Run app from android studio on my macbook. No problem! The database is 
fresh, and no existing data is found
5. Uninstall app again
6. Test again on my Windows machine. Now, the database comes back and the 
app sees the old old database info (from step 2!). Uninstall at this point 
doesn't get rid of it

So I really am at a loss now. Why would running on a Mac be OK? And why 
would, after running on a Mac and cleaning out the database, then bring the 
old Windows database again? Should this not all be OS independent?

[android-developers] App uninstall doesn't remove SQL database

['Simon Ho' via Android Developers]

I posted this on stackoverflow, but I thought maybe I'd have more luck 
here...

I have a strange problem where my SQL database doesn't remove itself when I 
uninstall the app

I'm not creating the database in any external storage directories, and the 
database is confirmed to be in its default location: 
/data/data/com.example.app/databases/

After I uninstall the app, I expect all the data in that location to be 
wiped, but when I run the app again from android studio the new install can 
still see all of the old data

I have tried using adb to manually delete the .db file from the databases 
directory, but when I run the app again the old data can still be seen

I have also tried going into the app settings and clearing the data and 
cache, but that doesn't seem to help

The only places in my code where I'm doing anything "strange" with regards 
to the database is I'm copying the database file to a new location on 
button click:

String pathToExternalStorage = Environment.getExternalStorageDirectory
().toString();
File exportDir = new File(pathToExternalStorage, "/SensorData");
File subjectDataDir = new File(exportDir, "/subjects");

File data = Environment.getDataDirectory();
String currentDBPath = "//data//com.example.app//databases//" + DBHelper
.DATABASE_NAME;
File currentDB = new File(data, currentDBPath);
File destDB = new File(exportDir, DBHelper.DATABASE_NAME);

FileChannel src = new FileInputStream(currentDB).getChannel();
FileChannel dst = new FileOutputStream(destDB).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();


And then running mediascanner on the newly created file so I can get 
instant MTP access to it

I doubt that either of these processes could cause this to happen though?

My immediate question is how do I manually remove the database from the 
phone without root access?

The bigger question is what could be causing the uninstall process to not 
remove the database files? And how does a newly installed version of the 
app (after an uninstall) still see the old database information?

I'm not sure how to begin figuring this out...

[android-developers] Emulators for WebView versions

[simon]

We make an Android wallet app called Jaxx. We have had recurring issues 
with some of our Javascript middleware in different versions of Android, 
and it's relating to the user's version of the WebView component that is 
installed. We are looking to obtain emulators of the different versions of 
the WebView component that have been published for each Android OS version, 
so that we can determine how the problem has arisen, and deterministically 
recover our clients' lost funds. Is this the best place to explore this, or 
is there some more direct route to speaking with Google developers about 
this?

I am working on an Android Running App and currently trying to implement a 
user chosen distance route. 
I have been looking with a few weeks and cant seem to find anything that 
can help. 
I have user location and updates working but the problem is I don't want to 
set a defined destination. 
I would like to be able to input a chosen distance be it 5 km and have a 
route/multiple routes displayed with the destination being the end of the 
distance.
Any help would be greatly appreciated.
Thanks

[android-developers] Why does NdsManager not work on Android Wear?

[Simon East]

scovery.start();
}

All I get back is


E/ServerDiscovery: Discovery failed: Error code:0

Error code 0 apparently means Internal Error which does not help much.


The phone the watch is paired to is off, and the watch is connected to the 
WiFi network and in fact in other tests I can open a socket to the server 
fine - so I think the networking side of things is all working - it is just 
NdsManager that is not working for some reason.


Anyone got any idea why this is not working?


Thanks, Simon.

[android-developers] ZipInputStream getNextEntry does not return file header info

[Simon Giddings]

This would appear to be a bug.

I create a zip file using ZipOutputStream with success.
I can then transfer it from the tablet to my PC and look at it with WinZip.
All files have the corresponding size, compressed size, and CRC values.

Now, if I open the zip with ZipInputStream and call getNextEntry, these 
values are not set.
Here is how I am reading the file :

try
{
// open the archive
FileInputStream fis = new FileInputStream(fArchive);
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
bBuffer = new byte[2048];

// iterate through all files, putting them back into the same place
ze = zis.getNextEntry();
while(ze != null)
{
strFileName = ze.getName();
strFileName = FILE_PATH + "/" + strFileName;
fCheck = new File(strFileName);
lZipFileSize = ze.getSize(); // <--- returns -1 systematically
lTargetFileSize = fCheck.length();
fCheck = null;
FileOutputStream fos = new FileOutputStream(strFileName);

// read the data
while((iCount = zis.read(bBuffer)) != -1)
{
fos.write(bBuffer, 0, iCount);
}
fos.close();

ze = zis.getNextEntry();
}
zis.close();
fis.close();
bOk = true;
}
catch(Exception e)
{
e.printStackTrace();
}


When I look into the source for ZipInputStream, I see the following code :
if (!hasDD) {
ceCrc = ((long) Memory.peekInt(hdrBuf, LOCCRC - LOCVER, ByteOrder.
LITTLE_ENDIAN)) & 0xL;
ceCompressedSize = ((long) Memory.peekInt(hdrBuf, LOCSIZ - LOCVER, 
ByteOrder.LITTLE_ENDIAN)) & 0xL;
ceSize = ((long) Memory.peekInt(hdrBuf, LOCLEN - LOCVER, ByteOrder.
LITTLE_ENDIAN)) & 0xL;
}

This is the only position that I can see where the values are retrieved, 
yet it is ignored because of the !hasDD condition.

Have I misunderstood something here ?

[android-developers] Getting the list of supported devices - encoding problems

[Simon Giddings]

I wanted to obtain the list of supported devices and then automatically 
process them.
I found this page : 
https://support.google.com/googleplay/android-developer/answer/6154891?hl=en

However, the file is encoded as UCS2 Little endian.

Is there a UTF-8 or unicode version available ?

It is important for me to be able to get this automatically, ie via php 
scripting which is unable to convert from UCS2-LE to UTF-8.

[android-developers] Re: How to change actionbar text case

[Simon Giddings]

If anyone is needing to do the same thing, here is my working solution.

Note that I am targeting API 14 and above.

style name=AppTheme parent=android:Theme.Holo.Light.DarkActionBar 
item name=android:actionMenuTextAppearance
@style/myActionBarMenuText/item
/style

!-- Override actionbar menu text appearance --
style name=myActionBarMenuText parent=
android:TextAppearance.Holo.Widget.ActionBar.Menu
item name=android:textAllCapsfalse/item
!-- was 12sp, which is too small for me in mixed case --
item name=android:textSize16sp/item
/style


I hope this will be useful for someone ...

[android-developers] How to change actionbar text case

[Simon Giddings]

I have developed an application which contains this app theme style :
 style name=AppTheme parent=android:Theme.Holo.Light.DarkActionBar /

I have tried various means to change the actionbar text to be mixed case 
instead of all uppercase.
To illustrate, here is a screen shot -

https://lh3.googleusercontent.com/-fL-5_3uD_z0/VbeuwHo1THI/ArM/4ZcuCqB2spU/s1600/actionbar-uppercase-text.jpg

The styles I have tried thus far have produced anything but the desired 
effect.

How do I restyle just the letter case of these items ?

[android-developers] Re: How to stop ActionBar getting focus

[Simon Giddings]

Ok, here is my solution ...

When the pedal keyEvent is processed in dispatchKeyEvent, send a message to 
the same activity to call requestFocus on the main content view.

Le mardi 14 juillet 2015 17:29:49 UTC+2, Simon Giddings a écrit :

 I have integrated the use of Bluetooth pedals, which declare themselves as 
 being a keyboard.

 When the pedal is pressed, my activity gets the keypress and, in 
 dispatchKeyEvent, I return true to indicate that I have consumed the 
 event.
 However, the ActionBar is still responding to the keypress by highlighting 
 the title button - I have already set setDisplayHomeAsUpEnabled as true.

 I then captured the corresponding area in the action bar and removed 
 focusable like this -
 int iActionBarTitle = 
 getResources().getIdentifier(action_bar_title, id, android);
 View v = findViewById(iActionBarTitle);
 v = (View)v.getParent().getParent();
 v.setFocusable(false);

 However, this just moved the focus to the first action item.

 I do not want to do a lot of hacking so as to avoid further difficulties 
 down the line.
 Not sure of how I can overcome this problem correctly.

 Can anyone guide me with this ?

[android-developers] How to remove blue cast on views

In my app, I create a music score dynamically in a custom view.
This is held within a fragment, which does not have any custom background

Here is a screen shot illustrating the situation ...

[android-developers] Migrating to Android Studio

[Simon Giddings]

I have been developing a large project for a long time now and am nearly at 
the point of wanting to release it.

However, I have seen that the official IDE is no longer Eclipse but Android 
Studio.
In addition, I have seen a number of discussions passing by where people 
are complaining about bugs within Studio.
Is Studio really in a production stable state yet ?

So, my obvious question here is - should I be migrating to Studio *now* ?

If so, are there any accurate guides for doing this ?
I have seen the, very, succinct description on the developers site which 
appears to skip certain steps.
For example, it says to import the project .gradle file - without 
explaining how to generate this file !

Hopefully someone will be patient enough to help me with this ... please ?

This is great - first class answer !
Thanks for reassuring me about this move - which I will indeed undertake 
after my first release.

 You should probably have migrated months ago. But at this point, do you 
 need to migrate this second? No. If Eclipse is working for you and you're 
 about to release, why complicate things with a new environment? I'd get 
 that release out the door, back up everything, create a new branch in your 
 repo, and start the process there.
  

 If so, are there any accurate guides for doing this ?

 I assume you're referring to this: 
 https://developer.android.com/sdk/installing/migrate.html, where in step 
 3 it says Locate the project you exported from Eclipse. So, while it's 
 not 100% explicit, it is indicating that you should have done an export 
 from Ecipse. Did you try that?

 Personally I found that transition fairly smooth. You don't even have to 
 export Eclipse first anymore. Just do an import in Android Studio and it 
 will detect the Eclipse project structure and import it for you. Give that 
 a shot.

[android-developers] Allowing underlying ScrollView to scroll

I have a ScrollView which fills the screen, within a RelativeLayout.
Positioned over this are a series of transparent Views placed in each 
corner as hotspots.
Their only purpose is to capture tap/click events.

However, I do not see how I can let dragging events be passed onto the 
underlying ScrollView.
This is needed as these hotspots are large.

Is there a simple way of doing this ?

Re: [android-developers] Re: Fragment animations using objectAnimator to slide over the previous fragment

Thanks for this Harri,

Tried it, to no avail.
In fact, what I have found is that the new fragment, when it is animated 
in, comes in *under* the existing fragment.
What I need is for it to be inserted *over* or *before* the existing 
fragment.
Cannot see how to do  this.

Not too happy about ViewPager as it is in the support library - which for 
me means that it is not stable code, at least not as stable as system code.

Any other thoughts ?

[android-developers] Fragment animations using objectAnimator to slide over the previous fragment

[Simon Giddings]

After having spent quite a bit of time searching for this, I need to 
request help here.

I have a series of fragments each representing a page.
I want to give the user a nice animation effect when going to the next page 
he has requested.

I want that the new fragment slides in *over* the previous fragment, hiding 
it as if it were a solid page.
At present I can slide in the new fragment, but we can still see the 
underlying fragment during the transition.

Here is my slide in transition definition :
?xml version=1.0 encoding=utf-8?
set xmlns:android=http://schemas.android.com/apk/res/android;
android:fillAfter=false 

objectAnimator
android:duration=500
android:propertyName=x
android:valueFrom=-1280
android:valueTo=0
android:valueType=floatType /
/set

And here is my fade out transition
set xmlns:android=http://schemas.android.com/apk/res/android; 
android:fillAfter=false 
objectAnimator
android:propertyName=alpha
android:duration=500
android:valueFrom=1.0
android:valueTo=0
android:valueType=floatType /
/set

I apply it with :
Fragment f = (Fragment)FragClass.newInstance();
FragmentTransactionft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.animator.fragment_slide_in, 
R.animator.fragment_fade_out);
ft.replace(R.id.fl_frame, f);
ft.commit();

I have seen the kind of effect I want being demonstrated with the ViewPager 
http://developer.android.com/training/animation/screen-slide.html#depth-page 
- but I am using Fragments.
Can this kind of transition (just the moving in from the left bit shown at 
the end) be achieved with fragment animation ?

[android-developers] Unable to see installed app via DDMS

[Simon Giddings]

I have just purchased and received my Samsung Galaxy Tab Pro 10.1 tablet 
(Android 4.4.2).
Just got over the panic of not seeing the developer options in settings = 
had to tap 7 times on the version number to get this displayed.

Now, I have started a debug session to install my app for continuing 
development.
I need to add data files to the installation location, but when I go into 
DDMS file explorer, it refuses to open the /data directory.
Is there a way of opening this, somehow ?

The file permissions are : drwxrwx--x
I presume that I will need to change it to drwxrwxrwx ?

Is this right ?

[android-developers] Creating a custom PreferenceScreen for configuring connected devices

[Simon Giddings]

My app will receive input from external bluetooth devices.
I want to be able to let the user configure the application according to 
the paired device present.

The obvious place for this is within the shared preference activity.
As I am only targeting tablets for this, I was wanting to take advantage of 
the side-by-side display as shown here =


So, the right hand screen (2) will need to permit the selection of the 
supported device, display a picture of it and permit the configuring of 
relevant parts.

Should I be deriving a new class from PreferenceScreen for this ?
If so, what do I need to do to get this form of flexibility ?
Is there a better way ?

[android-developers] Seeking layout advice

[Simon Giddings]

I am working on an application where the user can create a list of items 
(songs).
The user can also add a text block to the list - text to be read as an 
introduction to the next sequence of songs, for example.

It is with this text editer activity that I am having trouble deciding 
where to put things.
I am displaying it as a dialog and have therefore placed cancel and ok 
buttons at the bottom of the layout.
However, this means that they are hidden by the virtual keyboard when the 
focus is on the edittext widget.

In addition, I wanted to add the ability to paste text copied from 
elsewhere - another app, a web page.

After having looked in the design guides ... I am no further forward.

Should I rather be placing the cancel and ok buttons at the top of the 
layout ?
Should this rather be a full screen activity where I use the action bar to 
place a paste button ?
If I do this, should the cancel and ok buttons also be in the action bar ?

I hope someone can advise me with this as I am stuck at this point.

[android-developers] Re: Padding offsets for a TextView to perfectly align with an EditText

[Simon Giddings]

I agree, in the same way as using the relative alignments above.
However, as I stated, the displayed text is *not* at the same position - 
the EditText widget is higer and so there are offsets applied to the 
beginning of the text.

[android-developers] Padding offsets for a TextView to perfectly align with an EditText

[Simon Giddings]

I am building a layout where text is displayed in a TextView.
When the user taps on the text, I want to display an EditText widget to 
allow for the text to be modified.

I use a relative layout to ensure have the two widgets in the same position.
The edit text is declared first and then the the TextView is made to align 
to the top and bottom of the EditText.

However, I have seen that the text displayed in the EditText is offset down 
and to the left.
I need to ensure that, for the user, the text does not appear to move at 
all when switching to the EditText.

Do I need to use padding values to align the text displays ?
If I do, is this guaranteed to work on all displays ?

Here is the relevant part of my layout :

RelativeLayout
android:layout_width=0dp
android:layout_height=match_parent
android:layout_weight=1
android:paddingTop=15dp
android:paddingLeft=20dp

EditText
android:id=@+id/etListName
android:layout_width=match_parent
android:layout_height=wrap_content
android:layout_alignParentTop=true
android:layout_alignParentLeft=true
android:visibility=visible
android:textAppearance=?android:attr/textAppearanceLarge
android:text=List name /

TextView
android:id=@+id/tvListName
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_alignTop=@+id/etListName
android:layout_alignBottom=@+id/etListName
android:layout_alignParentLeft=true
android:textAppearance=?android:attr/textAppearanceLarge
android:visibility=visible
android:text=List name /

[android-developers] Seperate display on HDMI device

[Simon Giddings]

I am creating an application which needs to display on an HDMI connected 
screen, display content which is different to that displayed on the tablet.

This could be used in the context of presentations where the presenters 
notes are only displayed on the tablet and the illustration content on 
the HDMI output device.

Is there any resource which describes how to go about writing specifically 
to the HDMI output screen ?
Tutorials even ?

[android-developers] ActionBar strange behaviour

[Simon Giddings]

I am writing an application for Android tablets - version 4.0 (min sdk 14)

Here is the content at the start of the activity :

https://lh4.googleusercontent.com/-s7H2b2yp8Gk/Uo9E9VZP1XI/Am8/W0maYf5wefQ/s1600/actionbar_prb1.jpg

When I click (I am working in the emulator) on the plus button (to zoom in 
one level),  this is the result :

https://lh4.googleusercontent.com/-YP1eyEF13RM/Uo9FY9thC6I/AnE/VX-FuuZILZk/s1600/actionbar_prb2.jpghttps://lh4.googleusercontent.com/-s7H2b2yp8Gk/Uo9E9VZP1XI/Am8/W0maYf5wefQ/s1600/actionbar_prb1.jpg



If I remove the TextView control at the head of the ActionBar, this is the 
resulting visual behaviour :

https://lh5.googleusercontent.com/-D52Fjc3_60c/Uo9QWtiXGwI/AnU/WbKsz70aZ98/s1600/actionbar_prb3.jpg

https://lh6.googleusercontent.com/-CiWez7jbELA/Uo9QpMeOZuI/Anc/O11uYPVre7U/s1600/actionbar_prb4.jpg

The number button is defined in the menu as -

item
android:id=@+id/partion_songnumber
android:title=Numéro du chant
android:showAsAction=always 
android:actionLayout=@layout/actionbar_songnumber_btn /

The layout file is defined as

TextView xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@+id/tv_songnumber
android:layout_width=match_parent
android:layout_height=match_parent
android:paddingLeft=5dp
android:paddingRight=5dp
android:layout_gravity=center_vertical
android:clickable=true
android:textSize=29dp /

The menu is modified via the method onPrepareOptionsMenu

The content of this method is like this :

@Override
public boolean onPrepareOptionsMenu(Menu menu)
{
boolean bOk = super.onPrepareOptionsMenu(menu);
TextView tv;
int iZoomLevel = m_ZoomListHandler.GetCurrentPosition();

if(bOk)
{
menu.findItem(R.id.partition_zoomin).setEnabled(iZoomLevel  7);
menu.findItem(R.id.partition_zoomout).setEnabled(iZoomLevel  
0);

// set the songnumber
tv = (TextView)menu.findItem(R.id.partion_songnumber)
.getActionView();
tv.setText(String.format(%d, m_iSongNumber));
}

return true;
}
I have tried searching for why this happens, with no success.

Can anyone help me resolve this ?

[android-developers] Correcting the style of a drop down spinner in ActionBar

[Simon Giddings]

I am using the following theme : Theme.Holo.Light.DarkActionBar
My application targets a minimum SDK of v14 and I am inserting a spinner to

I have been searching for the correct way to correct the styling of the 
spinner so that it is visible within the actionbar - at present it is dark 
on dark.

How do I assign the correct, existing, system, holo styles to the spinner 
to get it to display correctly ?
I would prefer to not have to re-create the styles and have to copy 
resources from the SDK files if possible.

[android-developers] Navigation Drawer and using - over sized - icons

[Simon Giddings]

I would like to be able to use oversized icons within the Navigation Drawer 
listview items.

However, I have seen that, even if I put larger icons in the resource 
directories, they are all scaled down.
This is for working exclusively within a tablet application.

Is there a way around this automatic re-scaling ?

[android-developers] Navigation Drawer, Activities and Fragments

[Simon Giddings]

I am a bit confused here with this.

With the examples that I have seen for using the Navigation Drawer, they 
all point to using one unique Activity, with Fragments giving the actual 
content.
The advantage with this is that there is only one instance of the 
Navigation Drawer created.

However, in my application, I have distinct Activities which have distinct 
tasks (and, yes, there are indeed more than three).
Should I therefore be creating the same navigation drawer in each Activity ?
It is obvious that I would like to be able to preserve my existing 
activities and not have to re-write them as fragments.

My understanding is that fragments are not activities and activities are 
not fragments, are they ?

Have I correctly understood this ?
Can anyone give some advice here ?

Re: [android-developers] Navite Navigation Drawer

[Simon Giddings]

Well my, previous, understanding was that the support library was to 
provide functionality found in the most recent APIs, for earlier APIs.
So, stuff in the v4.0 could be used in v2.3 via the support library.

Perhaps you could clear something up for me.
When I use just *one *item in the support library, will I get *only* that 
item included in my apps files, or will *all of the support library* be 
packaged all the same ?

[android-developers] Navite Navigation Drawer

[Simon Giddings]

I have seen the Navigation Drawer and am interested in it for my v4.1 
tablet application.
However, I see that the documentation describes it as being within the 
support library.

My understanding was that this library was mainly for apps in and before 
v2.3 of android.

Is there not a native version of this feature available, or are we 
condemned to using the support library ?

[android-developers] Emulator plus HAXM blocks hibernation

[Simon Giddings]

I am developing a tablet app and have installed HAXM release 03 from intel.

When I want to put my PC into hibernate mode (Dell Vostro 1710 - Windows XP 
Pro SP3), I exit the emulator and eclipse, before going to hibernate mode.

However, the screen goes black and then nothing else occurs, leaving the 
only choice of turning off via the power button.

Has anyone else had this problem ?
Is there a workaround, fix ?

[android-developers] How to compress text data before saving in a database

[Simon Giddings]

I have a more than 800 records of data, of which each record will contain a 
variable size of text data.
It is this text data (anything between 800 bytes and 4kb) which I need to 
compress before putting it into the database.

It doesn't matter if the saving of the data is a bit long, it will be the 
reading and decompressing which needs to be fast and efficient.

Note that I am targetting tablet devices here.

Is there a recommended / best way to go about this ?

Thank you for the comments.
Yes you are right, I am targeting Android 4.0+.
I'll keep with my current rendering choice then.

 There are only two variables: are you running Android 3.0+ and are you

 In this particular case I doubt using OpenGL directly is necessary. 
 Android tablets run on Android 3.0+ so you can simply rely on built-in

[android-developers] Optimise drawing speed

[Simon Giddings]

I am writing a music notation app for android tablets.
As I draw everything (ie. this is not a simple image (jpg, pdf, etc) 
which needs displaying), I need to ensure that the choice of drawing method 
is the fastest possible.

My options, as I see them at present, are

   1. Classic on-screen drawing.
   2. Draw on a memory based canvas and bitblt the resulting bitmap onto 
   the screen

Will either option give better rendering time results ?

I have chosen to use classic drawing methods, rather than an OpenGL type 
surface.
Is this a mistake ?

Any help will be appreciated.
Thank you

[android-developers] SMSManger sendTextMessage - never get deliveryIntent

[Lindsey Simon]

Do you need RECEIVE_SMS permission to receive the deliveryIntent by any

Here is my code - any help would be CRAZY appreciated =)
I always get the sent intent but never the delivery one.

int status = -1;
String details = ;

[android-developers] Might locationManager requestLocationUpdates / removeUpdates for dynamic config cause the GPS to completely stop working?

[Lindsey Simon]

I've got an app where we want to have dynamic values for minTime and 
minDistance depending on someone's proximity to their destination.

To accomplish this I'm just calling removeUpdates and then 
requestLocationUpdates after a period with different values. We pause 
anywhere from 15seconds to 3 minutes between these start/stops.

The problem is that on some devices we're seeing a situation where we just 
stop getting location updates. On a Galaxy S3 for instance, the GPS 
completely stops working - no app can get a location in fact. Only 
rebooting the phone seems to fix the problem.

Maybe I'm start/stopping the watches too aggressively and hitting some sort 
of bug?

Any insights would be extremely helpful.

I've found a few similar reports of this situation:

I should add that while no other app can get a location, it seems like 
Google Maps is working aok.

[android-developers] High Resolution Application Icon Spec

[android-developers] Re: Help: My app has violated the spam provisions of the Content Policy

[Simon Frederic]

Hi Everyone,
I am facing a similar issue with an app I posted last year for testing. 
Event Animals.
the app was downloaded  10 times (for testing only)

I received a similar email. No explanation whatsoever for the suspension; 
and unfortunately no response whatsoever to email.
 Post suspension I can see five install to 31 ratings.  Which might very 
well be the reason for the suspension- 

I don't think it is possible from backend to remove comment (or else 
everyone would remove bad ratings) - 
I don't think it is possible for me to re-submit the apk (right?)

This apk took one year of developement to create and now it is forced out 
the market for reasons that are being my control. 
I am not asking how to get reinstated but would like to get information to 
logical step that would potentially solve this issue from people that might 
have experience something similar.
Google China tell me they don't have the authority to manage the app from 
here.
Google US developer dont reply to emails (they never did - even when I had 
trouble paying the developer fee )


Any word of advice. or shared experience would be greatly appreciated.

Frederic

[Lindsey Simon]

I have a feature in my app I'd like to not turn on for users who have

[android-developers] Video editor API

[Simon Buckle]

I have a question about the Android SDK (for Jellybean). In the Android 
source tree there is a 'videoeditor' package (
https://github.com/android/platform_frameworks_base/tree/master/media/java/android/media/videoeditor)
 
yet when I try to import the classes in this package into my project, they 
don't appear. I had a look at the contents of android.jar and sure enough 
the classes in that package are not present in the JAR file; I've tried the 
SDK on both Mac and Linux.

How can I use these classes in my Android projects? If they are in the 
source tree then I assume I must be able to use them somehow.

Thanks

[android-developers] Creating data files as compiled (binary) xml

[Simon Giddings]

I am developing a tablet application where I want my data files to be 
stored as compiled xml.
The application will not, itself, be creating these files.
These files will be added at a later stage - the user will be able to 
purchase them separately.

So, my question is, how can I create the compiled xml in a format which I 
can then read within my application ?
Is this even possible, or will I need to create my own compiler ?

Re: [android-developers] Creating data files as compiled (binary) xml

Hi Mark,

Why - to create my data files - sheet music data - and distribute them in 
a fairly protected manner.
Yes, I am indeed referring to the xml binary format used by the build 
process.

 Why? 

 Furthermore, what do you consider compiled xml to be? 

 If you are referring to the binary XML format created by the build 
 process for XML resources, you would have to root around in the source 
 code to find both the compiler and their version of the 
 XmlPullParser that reads it in, and modify those to suit your needs.

[android-developers] Scaling emulator size to real size from eclipse

[Simon Giddings]

I know that we can start the emulator from the AVD manager and use the 
Scale to real size parameters.

However, when the emulator is started from within eclipse via a debug 
request, it will start a new instance of the emulator without scaling the 
window size.
How can I start the emulator from a debug request within eclipse and 
include the scaling parameters?

[android-developers] Intel x86 image for 4.1.2

[Simon Giddings]

I have installed the intel x86 image for 4.1.2 (API 16) via the SDK Manager.
Now, when I go into the AVD Manager and select a target of Android 4.1.2 - 
API Level 16, it still automatically selects the ARM CPU/ABI and disables 
the dropdown list.

How do I get it to recognise that the x86 system image has been installed 
and is available ?

[android-developers] extend class and constructors

[Simon Giddings]

This may seem a bit basic, but I come from a C++ background and it is 
confusing me a little.

When I extend a base class, do I need to create a constructor for each base 
class constructor ?
What I mean is this. Given :

public class base
{
protected int m_iValue;

public base()
{
m_iValue = 0;
}

public base(int iVal)
{
m_iValue = iVal;
}
}

If I want to create a new class based on this base class, will I need to 
declare the two constructors again for them to be visible ?
The following seems to hide the second constructor of the base class.

public class Derived extends base
{
public Derived()
{
super();
}
}

What is the correct way to do this ?

[android-developers] Re: Drawing complex shapes with hollow parts

[Simon Giddings]

In fact, after doing some further work on this, this is what I have found :

The simplest way of achieving this is to 

   1. Create the path object
   2. Set the fill type to  Path.FillType.WINDING .
   3. draw the outline segments using lineTo, cubicTo, etc, ensuring that 
   the outline closes itself.
   4. draw the inner holes, each one using a different direction. ie: if 
   the outline was drawn clockwise, then the first hole must be 
   anti-clockwise, the second clockwise, etc...
   5. Draw the path on the canvas with  Canvas.drawPath(...) .

[android-developers] Using a symbol font

[Simon Giddings]

I have seen that it is possible to use custom fonts within our Android apps.
I am starting to build an app for tablets and need to use a specific symbol 
font.

I place it in a font directory under assets and load it via the 
Typeface.*createFromAsset* method.
I get back a Typeface object and assign it to my Paint object and then 
paint it out onto the canvas.

However, instead of getting the symbols, I get normal text.

Is there a special step necessary to get symbol fonts to output correctly ?

Re: [android-developers] Using a symbol font

[Simon Giddings]

Thanks Mark,

I had created a very simple project to try this out.
So, it would appear that I will have to look at a different method for 
drawing symbols.

Thanks again

  I have seen that it is possible to use custom fonts within our Android

  I am starting to build an app for tablets and need to use a specific

  I place it in a font directory under assets and load it via the 
  Typeface.createFromAsset method. 
  I get back a Typeface object and assign it to my Paint object and then 
 paint 
  it out onto the canvas. 
  
  However, instead of getting the symbols, I get normal text. 
  
  Is there a special step necessary to get symbol fonts to output 
 correctly ? 

 Android does not honor all custom fonts, substituting the default font 
 silently. 

 I'd start with a font that is known to work, such as the one in this 
 sample project: 

 https://github.com/commonsguy/cw-omnibus/tree/master/Fonts/FontSampler 

 If that fails, then there is something wrong with the application 
 logic (or that font has started failing on devices, where it has 
 worked for years). If that font succeeds and your symbol font fails... 
 you will need to find another symbol font, or perhaps try slightly 
 modifying that symbol font in some font editor in hopes that the 
 newly-saved font will work with Android.

Re: [android-developers] Canvas or OpenGL

[Simon Giddings]

Thank you to every one for their responses.

It would seem, however, that my question was not clear enough (you are 
right James).

I am going to write a music notation app.
So, will simply be writing the music score on the display - no animation 
needed.
My question was about visual scaling - reproducing a sheet of music paper 
and then permitting the user to zoom in and out.
Hence the reference to world coordinate and screen coordinate conversions.

Please note - this will *not* be using pdf documents !

Can I still achieve this with Canvas ?
Is there an example of the correct way of producing this kind of scaling 
when using Canvas ?
I will be targeting tablet systems with this.

 You can do 60fps drawing with either OpenGL or Canvas.  That is the best 
 you are going to get for accuracy since that is the screen refresh rate.

Do you know of any ?

[android-developers] Canvas or OpenGL

[Simon Giddings]

I am going to start the development of a Music document app.
In the past, when I developed under widows, I used world coordinates and 
screen coordinates to provide scaling/zooming.

I am unclear as to weather I should go to OpenGL under Android, or if I 
could still use Canvas.

Can anyone advise me here?

[android-developers] Fragments : Advanced example or tutorials?

[Simon Engler]

Good Day,

I am trying to create a user interface for driving a robotic platform 
around. I have a number of programs that work indpendantly displaying 
video, logs, or graphical representation of a compass etc.

I follow tutorials given online, but when I try to implement my programs 
crash. The tutorials are simply, fragmenting lists to display text. They do 
not seem to work for displaying two different activities which are 
converted into fragments.

Are there any advanced user interface tutorials or shareware available that 
I can work with?

[android-developers] Creating custom icons with Photoshop - dip

[Simon Giddings]

This subject is causing me some conceptual problems.

In the official documentation, it states that 1dip represents 1 pixel in a 
160dpi screen.
Does this mean that we should be creating graphic elements at a resolution 
of 160 dpi instead of 72 dpi ?

I hope someone will be able to give an authoritative answer to this 
question.

[android-developers] Odd launch fail with r20 SDK

[Simon T]

I updated to SDK r20.0.1 a few days ago and since then my application fails 
to launch on an emulator or handset. I get 'unable to instantiate launch 
activity (class not found) error' - it seems the main activity is not in 
the APK. However there is no sign of any bug in Eclipse. My code worked 
fine before the update, and continues to work fine on another machine with 
an older SDK. The manifest and R,java etc all tie up. I'm developing for 
API 8 by the way - it is a game so it uses a simple stub as the activity 
that sets up an update thread for the main class and a Frame Layout. I have 
uninstalled the SDK and re-loaded it and simple 'Hello World' applications 
will work. Anyone any ideas - I'm completely out?

Re: [android-developers] DialogFragment - show soft keyboard upon creation

[Simon Giddings]

Ok, all is working now.
The problem came from wanting to only enable the ok button once a minimum 
number of characters had been entered.
I was doing this through setOnKeyListener - this blocked the soft keyboard 
appearing automatically (if the user touched the edittext, the soft 
keyboard showed anyway).
So, I have removed this call and now use the following with success :
getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

 Everything around the Android keyboard feels hacky. 

 Try one of the following:

 1) Set requestFocus/ in your XML in the edittext.
 2) do a post such as et.post(new Runnable() { et.requestFocus() }} etc.
 3) do a post again but your use own code in your original post.

 Good luck.

 I have a simple dialog built with the compatibility libraries

 It holds only 

1. EditText 
2. 2 buttons

 When the dialog is shown, the edit text control has the focus.
 At this point, I want to open the soft keyboard automatically.

 Here is what I am doing within the onCreateView method :
 EditText et;
 et = (EditText)v.findViewById(R.id.**txtAddress);
 Activity act = getActivity();
 if(act != null)
 {
 InputMethodManager imm = (InputMethodManager)act.**
 getSystemService(Context.**INPUT_METHOD_SERVICE);
 if(imm != null)
 imm.showSoftInput(et, InputMethodManager.SHOW_**FORCED);
 }

 Even though I get to the showSoftInput step with no problem, the 
 keyboard is still not displayed.

 So, how can I correctly get the soft keyboard to be shown ?
