Re: [android-developers] Reading ROM version through code

[JP]

And as we all know... the trees do not grow into the sky ;-)

This morning, I tried this with a few Sony Ericsson phones I had at the 
office. And they do not return anything when I try to get the 
ro.product.version property. I still get the ro.build.fingerprint, but 
nothing else.

Does anyone know if there is a place I can read the different handset 
providers property names? A wiki somewhere...?

[android-developers] Android and Elcipse create new project error: SDK not installed and missing a file.

[Rich]

I'm having a problem creating a new Android project in Eclipse. I have 
installed Eclipse, ADT 18.0.0 and the latest SDK 19 but I get an error when 
I try and create a new project. I'm able to select an Android project type 
but when I get it a name I get the error that I don't have the latest SDK 
and that I'm missing the file /tools/lib/progaurd-project.txt. I see that 
file in the folder from where the original SDK was downloaded and 
extracted. Am I to copy that file to another location or is the SDK 
installer/wizard to do that. I'm running Fedora 16 fully patched.

[android-developers] Saving files (pdf/doc) to /data/data(appname)/files folder from Assets

[Kris G]

I have pdf files and other documents stored in the "assets" folder of
my workspace. I want them transfered to the /data/data/(packagename)/
files directory as soon as the app is installed or on first run. I
wrote, with help, a section of code that is supposed to do that. But
when running nothing happens. No errors in logcat either. I feel like
it is something stupid that I am missing but since I'm a novice I am
not quite sure.  I also want it to handle opening pdf files as
necessary hence the code near the bottom.  Here is the entire code of
the file.

public class TestActivity extends Activity {



   public void copyFileOrDir(String path) {
   AssetManager assetManager = this.getAssets();
   String assets[] = null;
   try {
   assets = assetManager.list(path);
   if (assets.length == 0) {
   copyFile(path);
   } else {
   String fullPath = "/data/data/" +
this.getPackageName() + "/"
   + "/files/" + path;
   File dir = new File(fullPath);
   if (!dir.exists())
   dir.mkdir();
   for (int i = 0; i < assets.length; ++i) {
   copyFileOrDir(path + "/" +
assets[i]);
   }

   }
   } catch (IOException ex) {
   Log.e("tag", "I/O Exception", ex);
   }
   }

   private void copyFile(String filename) {
   AssetManager assetManager = this.getAssets();

   InputStream in = null;
   OutputStream out = null;

   try {
   in = assetManager.open(filename);
   String newFileName = "/data/data/" +
this.getPackageName() + "/"
   + "/files/" + filename;
   out = new FileOutputStream(newFileName);

   byte[] buffer = new byte[1024];
   int read;
   while ((read = in.read(buffer)) != -1) {
   out.write(buffer, 0, read);
   }
   in.close();
   in = null;
   out.flush();
   out.close();
   out = null;
   } catch (Exception e) {
   Log.e("tag", e.getMessage());

   }
   }

   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);
   Button Section = (Button) findViewById(R.id.Button);
   Section.setOnClickListener(new View.OnClickListener() {

   public void onClick(View v) {
   // TODO Auto-generated method stub
   Intent i = new Intent(TestActivity.this,
Section.class);
   startActivity(i);

   }
   });

   Button OpenPDF = (Button) findViewById(R.id.pdfButton);
   OpenPDF.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
   File pdfFile = new File("file:///
android:asset/keepitsmall.pdf");
   if (pdfFile.exists()) {
   Uri path = Uri.fromFile(pdfFile);
   Intent pdfIntent = new
Intent(Intent.ACTION_VIEW);
   pdfIntent.setDataAndType(path,
"application/pdf");
 
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   try {
   startActivity(pdfIntent);
   } catch (ActivityNotFoundException
e) {

   "No

   }

   }

   }

modify the framework to capture this event to do the same works?

[android-developers] Color Banding solved

[Diljeet Kumawat]

Color Banding Solved ooyyyeaa

I solved color banding in two phases

1) * when we use the BitmapFactory to decode resources it decodes the
resource in RGB565 which shows color banding, instead of using
ARGB_, so i used BitmapFactory.Options for setting the decode
options to ARGB_

second problem was whenever i scaled the bitmap it again got banded

2) This was the tough part and took a lot of searching and finally
worked
* the method Bitmap.createScaledBitmap for scaling bitmaps also
reduced the images to RGB565 format after scaling i got banded
images(the old method for solving this was using at least one
transparent pixel in a png but no other format like jpg or bmp
worked)so here i created a method CreateScaledBitmap to scale the
bitmap with the original bitmaps configurations in the resulting scale
bitmap(actually i copied the method from a post by logicnet.dk and
translated in java)

BitmapFactory.Options myOptions = new BitmapFactory.Options();
myOptions.inDither = true;
myOptions.inScaled = false;
myOptions.inPreferredConfig = Bitmap.Config.ARGB_;//
important
//myOptions.inDither = false;
myOptions.inPurgeable = true;
Bitmap tempImage =
 
BitmapFactory.decodeResource(getResources(),R.drawable.defaultart,
myOptions);//important

//this is important part new scale method created by someone
else
tempImage = CreateScaledBitmap(tempImage,300,300,false);

ImageView v = (ImageView)findViewById(R.id.imageView1);
v.setImageBitmap(tempImage);

// the function

public static Bitmap CreateScaledBitmap(Bitmap src, int dstWidth,
int dstHeight, boolean filter)
{
Matrix m = new Matrix();
m.setScale(dstWidth  / (float)src.getWidth(), dstHeight /
(float)src.getHeight());
Bitmap result = Bitmap.createBitmap(dstWidth, dstHeight,
src.getConfig());
Canvas canvas = new Canvas(result);
//using (var canvas = new Canvas(result))
{
Paint paint = new Paint();
paint.setFilterBitmap(filter);
canvas.drawBitmap(src, m, paint);
}
return result;

}

Please correct me if i am wrong.
Also comment if it worked for you.

I am so happy i solved it, Hope it works for you.

[android-developers] Images in a list..

[alv]

I have a ListActivity with my own ListView class and Adapter to add
data to the list.. I also have a unique rowitem latyout that defines a
TextView and 2 ImageView items:
http://schemas.android.com/apk/res/android";
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:orientation="horizontal">











I am able to drag and drop rows, as well as respond to clicks of the
images of the rows.. My question is, how can I figure out what row a
clicked ImageView object is in?  The images are used to edit and
delete row data... I can see the click but I cant seem to reconcile
what row the image is in?  Thanks!!

[android-developers] When does the binder thread pool shrink?

[Michael Hsueh]

I am reading through the binder code and trying to understand how the
threading works. I know that the binder driver sends commands to
increase the thread pool size when it detects that there is no free
binder thread to service a command (up to the max of 16 threads). But
I am not sure when these newly spawned threads are removed.

In IPCThreadState.cpp:

void IPCThreadState::joinThreadPool(bool isMain) {
...
   result = executeCommand(cmd);
...
if(result == TIMED_OUT && !isMain) {
break;
}
...
}

I see that the thread breaks out of the thread pool loop when result
is set to TIMED_OUT, which in turn happens when the binder drive sends
a command of BR_FINISHED. This would result in the handling binder
thread to leave the thread pool and essentially end. But I looked
through the binder driver source code and could not find any instance
in which the driver would deliver this command to binder thread. Does
this mean the binder thread pool will only grow in size and never
shrink?

I would appreciate any help on this topic.

[android-developers] Why installation or updation of android development kit directly in Internet is too slow ?

[Padeeprajkumar]

Hi,
I'm using Android SDK manager 4.03 in fedora 15.
I have an internet connection of minimum speed of 32 kilo bytes per
second, but still it downloads the updates at the rate of just 3 to 4
kilo bytes per second.
Installation and updation of the SDK tools in android sdk manager is
too slow. Seems the server allows only a limited speed for every
connected client. Is there any way I can increase the speed of
download of new packages marked for updates.

[android-developers] Android SDK and Eclipse Error "You don't have the latest SDK installed"

[Rich]

Hello,

I'm having a problem creating a new Android project in Eclipse. I have
installed Eclipse, ADT 18.0.0 and the latest SDK 19 but I get an error
when I try and create a new project. I'm able to select an Android
project type but when I get it a name I get the error that I don't
have the latest SDK and that I'm missing the file /tools/lib/progaurd-
project.txt. I see that file in the folder from where the original SDK
was downloaded and extracted. Am I to copy that file to another
location or is the SDK installer/wizard to do that. I'm running Fedora
16 fully patched.

Thanks,

Rich

[android-developers] Re: How to bring an overlay to the front?

[Alex Browne]

You can easily remove an overlay from your overlay list.
First you must have a MapView and obviously an Overlay.

private MapView map=null;

Overlay MyOverlay = new Overlay();

Then you can choose between removing the overlay referencin the object name 
(overlay name) o with its index (position in the overlay list).

map.getOverlays(); --> This is the list with all the overlays you have in 
the MapView.

The same way you add an overlay: --> map.getOverlays().add("object 
name/index position");

You can remove it: --> map.getOverlays().remove("object name/index 
position");

You might want to save the index position at the time you create the 
overlay:

Overlay MyOverlay = new Overlay(); 
int MyOverlayPosition = map.getOverlays().IndexOf(MyOverlay);

and then remove it whenever you want.

map.getOverlays().remove(MyOverlayPosition);

Hope this is usefoul to you. I just started with android so im not much of 
an expert :)

[android-developers] Layouts - Using Remaining Space For Intermediate View

[JTeagle]

I'm using RelativeLayout to create rows of controls and would like to 
achieve the following: 
 
Widget 1 - natural height 
Custom view - remaining space after Widgets 1 and 3 
Widget 3 - natural height 
 
If I add the view in the correct order and use FILL_PARENT, it uses the 
remaining space at that point - i.e., all following controls aren't visible 
as there's no more room. 
 
If I add the view at the end, using the BELOW rule to position below Widget 
1, it does that - but overlaps all following controls (e.g. Widget 3, since 
that was set to be below Widget 1 as well). 
 
I tried adding a second rule to say ABOVE Widget 3, but then it didn't seem 
to place the view at all (or made it zero height?). 
 
I can't seem to measure the controls even after calling setContentView(my 
relative layout), they always return zero - so I can't even calculate the 
remaining space manually and use that. 
 
Is there another way to achieve this, or is there a way to measure the 
desired height of a control? I tried calling measure(some width, 
MeasureSpec.UNSPECIFIED) (after setContentView() ) but that also returned 
zero - very helpful. 
 
If there were a way to get notified when the layout takes place (so I can 
call the superclass to actually lay out, then measure / calculate heights 
and re-layout with a fixed height for the view) then that would help, but I 
can't find anything like that either. I would rather not use a fixed height 
and a scrolling view, as scrolling makes an app less pleasant to use 
(unless it's meant to be a list of things!). 
 
If possible, I would like the solution to be compatible with 2.1 (API 7). 
 
Thanks in advance.

[android-developers] Stop sounds after leaving app

[Anderson Leite]

I am developing a game. This game starts a sound in the beginning and goes 
on during all the game.

If I press Home button, and go to any area of android, the sound keeps 
playing, until I really force the app to stop.

Whats the best aproach here ? 

There is some callback/listener, something that is called when app is not 
being used, but still running ?

If so, would be the right aproach just to mute the sound ?

I am developing this game using cocos2d, but this does not sounds like a 
cocos2d question..

Thanks in advance,

Anderson

[android-developers] Adding in-app products. Any limitations?

*Hi!*
*I have a problem with batch import of a CSV file with my products, that 
I'd like to sell using in-app billing.*
*The documentation claimes it's possible, I have prepared a correct file 
and...*

1. I have created CSV file with over 2.000 products
2. It has been processed, but only some 150 products were saved
3. I'm trying to upload the same file again, with 'overwrite' checked and 
I'm repeatedly receiving the information: "Cannot process sent file. Check, 
whether the limit is not exceeded."
4. Moreover - I get this message only under IE. Under Chrome or FF just 
nothing happens.
Please, I need urgent help, because I canit find answers anywhere on the 
internet and I just stucked. I'd like to offer full in-app biling 
functionality.
There is also no information in the documentation, that would describe any 
limitations when batch importing products from CSV.
 
Best regards,
Tomek

The intent does have the proper permission in manifest:

MANIFEST:

...

following code in Push_Activity.java triggers the exception:
com.google.android.c2dm.C2DMessaging.register( this,
com.exclusive26.igale.Config.C2DM_SENDER );

parameters sent correctly (Push_Activity context and some email
address <-- static final String) to C2DMessaging.register :
public static void register(Context context,String senderId) {
Intent registrationIntent = new
Intent(REQUEST_REGISTRATION_INTENT);
registrationIntent.setPackage(GSF_PACKAGE);
registrationIntent.putExtra(EXTRA_APPLICATION_PENDING_INTENT,
PendingIntent.getBroadcast(context, 0, new Intent(), 0));
registrationIntent.putExtra(EXTRA_SENDER, senderId);
context.startService(registrationIntent);
// TODO: if intent not found, notification on need to have GSF
}


the fail point is when triggering the following line (cant debug the
code in context.startService ) :
context.startService(registrationIntent);
the context is Push_Activity the intent contains new intent with
extras : { act=com.google.android.c2dm.intent.REGISTER
pkg=com.google.android.gsf (has extras) }
the second EXTRA is :
intent.putExtra("sometxt",PendingIntent.getBroadcast(context, 0, new
Intent(), 0)); - all this is sent to context.startService(intent);


The thing is, when I try to run this code in a new project it works.
the only difference i can think of is that the Push activity is the
LAUNCHER activity, and in the project that throws this exception its
not.
Please shed some light. thanx!!

[android-developers] Canvas performance for games

[Tony Houghton]

I'm new to Android and Java, learning by porting a game I wrote years
ago . Based on the book "Beginning Android
Games" by Mario Zechner, I'm using the technique of creating a fixed size
android.graphics.Bitmap (640x480) in RGB_565 format, rendering the game
tile by tile to its canvas with drawBitmap(bmp, srcRect, dstRect, 0),
then blitting the 640x480 bitmap to a SurfaceView's canvas, also using
drawBitmap().  AIUI drawBitmap() will scale if necessary, but I've only
tested with 1:1 scaling on an 800x480 device, leaving a gap on the side.
All the above is done in a separate thread, using a SurfaceHolder.

It's too slow, even without the debugger attached. The test device is a
ZTE Blade. The original ran at 50fps and looked nice and smooth. I'll
probably run the Android version a bit slower to compensate for
controller difficulties, but I'd like to keep the same amount of
movement per frame. I could halve the framerate and double the movement
per frame, but I think I'd struggle to reach even 20fps, and dropping
the rate further would make it unpleasantly jerky.

I've added some basic profiling and got some average times:

Game logic: < 1ms, fine, but still a lot to be implemented
Rendering the game tile by tile: 46ms, too slow
"Blit": 8ms, not too bad but would need improving to allow time for
all the other stuff

The core of the stage that's too slow consists of rendering tiles. Each
tile is 32x32 pixels and the game world is made up of 20x15 of them.
There's one source pixmap, also RGB_565, containing all the tiles, and
the correct 32x32 portion for each tile is obtained by the srcRect.

I don't think I could significantly improve the logic of the loop that
does the tile rendering, but I could change the paradigm so that I only
render the tiles that have changed between frames. However, the draw the
whole world on each frame technique is nice and simple and used to work
even back in the days of Acorn computers with <100MHz ARMs, and I want
to progress to writing 4 way scrolling games, where the whole screen has
to be updated every frame. And even in this one I sometimes have to
update a whole load of tiles at once when there's a big explosion chain.

So I think it's just too slow to use Canvases and Bitmaps this way. Is
the answer to my problem to use OpenGL?

Re: [android-developers] Google I/O device in reboot loop.

[Karl Pohl]

This seems to be a common problem .the first thing you can try - and this
works sometimes - when the tablet is shutdown hold the power button and
volume button together down when reboot and this will reset the tablet.
Next thing - call samsung they will give you a return label and you should
have the tablet back in about 10 days

[android-developers] Textpaint vs textview : Text coming blurry with textpaint

[CC]

Hi,

I am not sure if this topic has been covered before since I was unable
to find it in search. I am using the following code to populate text
on screen. But the text is coming blurred instead of crisp (as it
comes with textview). What else do I need to do?


textpaint.setAntiAlias(true);
textpaint.setStyle(Style.FILL);
textpaint.setColor(Color.DKGRAY);
textpaint.setTypeface(font);
textpaint.setTextSize(fontsize);
textpaint.setTextAlign(Paint.Align.LEFT);

[android-developers] which webservice to get Images?

[Rushyang Darji]

Hey guys,
I want to develop "Wallpaper" application for android. It is obvious that I
will need a webservice integration in my app. My budget is thin, so can't
afford to buy host/set up server etc.

I need some start up tips/links/anything about on which public image
hosting site should I upload images, which suppose to appear in the
application when it is ready. I don't want to show all wallpapers from
image hosting site in my app, but just the ones which I upload in some sort
of account. I would greatly appreciate ANY tips/link to tutorial given
regarding this subject.

regards,
Rushyang Darji

[android-developers] HTTP internet connection

[Atul]

Hi, I have an app which talks to an external http server hosted on a
data center. The app is working fine with Emulator under Eclipse on
laptop connected through wifi to ISP's router. However when I create a
signed app and download to an ICS tablet, the application goes upto
http getconnection and does nothing. The tablet is connected to wifi
and all standard applications are able to use the wifi. The
AndroidManifest.xml contains permissions for Internet and
Access_Network_State.

a. What can be the reason why app is not able to connect to network ?
b. Are there any debugging tools to see what could be happening ?

[android-developers] Android permission denial : when using content provider within the same application that host the content provider

[Romain]

Hello, I have a very strange bug with my content provider, and I don't know 
why.

I have 2 applications, 

1 : it is for having an UI to change parameters and it's hosting the 
content provider with all the parameters
2 : it is display some text and it's using the parameters stored in the 
content provider of the first app.

I have declared a content provider in my first app : 

 


with the specific permission : 





and in both apps, i've setted "" 

In the second app (who has not the content provider), it works like a 
charm, no problem at all.

But in the first app who host the content provider, it works at begin, but 
after few calls, I've got this : 


04-27 16:11:21.618: E/android(10922): Permission Denial: reading 
com.telorion.core.parameters.ParametersContentProvider uri 
content://com.telorion.core.parameters.ParametersContentProvider/telorionparameters
 
from pid=0, uid=10024 requires com.telorion.core.parameters.READ_PARAMETERS

04-27 16:11:21.618: E/android(10922): java.lang.SecurityException: 
Permission Denial: reading

04-27 16:11:21.618: E/android(10922): at 
android.content.ContentResolver.query(ContentResolver.java:311).

And I don't understand why.


I've tried to create a third app who is using the content provider, and it 
worked without any problems. So the problem is coming from the first app 
who is hosting my content provider. But I don't know why after some calls I 
have a "permission denial". Can somebody help me ?

Thanks a lot for you help :)

NB : When I remove the "readPermission" it works well in my 2 apps. But I 
don't want all apps can use it.

Re: [android-developers] sdk version

[Rushyang Darji]

It depends what kind of APIs you have used in your application. First
you'll have to test that app on different AVDs and then real devices.
Finally you'll have to specify SDKVersions in Manifest.

[android-developers] Question regarding Keystore and Developer Console

[TullyK]

I recently published an app to Google Play which I now want to update.
When I try to export the new apk from Eclipse it says 'Invalid
keystore format' It seems like my original apk file has overwritten
the keystore! Normally it puts .apk at the end of the file name but
this time it did not, and as I have the same name for the keystore and
the apk I fear the key store has been deleted, is this possible?

So now I can't update my app because if I use a new keystore it won't
let me upload it. So I tried making a completely new application on
the Developer Console but it obviously  doesn't let me have two
applications with the same package name. Having done a small amount of
research it seems impossible to delete my original applications from
the Developer Console?

Is the only solution to change the package name and upload it as a
brand new application, leaving the old one forever as 'unpublished'?

Thank you very much in advance for your help.

[android-developers] Re: how to detect difference between 5 and 7 inch screen

[JTeagle]

>How can i detect the difference between 5 and 7 inch screen.
Would the DisplayMetrics class (using a combination of xdpi and 
widthPixels, for example) give you what you need?

Re: [android-developers] How to force quit a Thread

[Kamran Shamim]

Thank you , Kristopher. That is an interesting read. This is an interesting 
discussion as it addresses a (probably) common situation. 
My penny's worth: Would it not be better to run the connection through a 
service, rather than a thread? I have a feeling that this would be easier 
to manage in the case described.
An alternative would be to use an AsyncTask and use cancel(booelan) to stop 
it, and isCancelled() in the task (and therefore the thread essentially 
watches itself to speed up the kill).

[android-developers] Native Maps Api - zoom to geocode returned viewport

[Simon Giddings]

This is a question I asked on Stackoverflow for which I got no answer.

When I make a query to the Google Maps Api Geocode web service, the answer 
comes back with a number of elements :

   - Coordinates lat / lng
   - Viewport NE and SW
   -  others 

The viewport is that which "contains the recommended viewport for 
displaying the returned result, specified as two latitude,longitude values 
defining the southwest and northeast corner of the viewport bounding box. 
Generally the viewport is used to frame a result when displaying it to a 
user."
Example given in the documentation :

"viewport" : {
   "northeast" : {
  "lat" : 37.42426708029149,
  "lng" : -122.0840722197085
   },
   "southwest" : {
  "lat" : 37.42156911970850,
  "lng" : -122.0867701802915
   }



I have not been able to figure out how to adjust the zoom level to best 
match this viewport.
Can anyone advise me on this ?
Perhaps someone has already done this and would be willing to share ?

[android-developers] How to send vCard via SMS?

[SamuelSpring]

I'm looking for any way to send/read a vCard via SMS in my app. I've
read a lot of articles, web-pages, forums etc. There is still not even
a clue how to do that.

Here is transaction.
1. User selects some specific contact
2. App generates a vCard for it
3. User types a number to send vCard to
4. App sends SMS with that vCard(?)
5. Addressee recievs SMS with vCard and asked to browse contact/add to
contacts(?)

There are some posts on stackOverflow about it, but still nothing
useful...

I've found this nice library to work .vcf files(both write and read).
http://code.google.com/p/android-vcard/

But is there any way to send it to another phone (and read properly of
course)? Just send this as a string maybe?

Please help! I'll be happy to get any clue, useful library or a proof
that it's impossible on Android. If there is no way via SMS can you
give me advice how to do that via MMS?

What's interesting, that there is a lot of apps with that
functionality, so I guess this is possible.

Thanks anyone who responds. Have a good day.

[android-developers] Documentation for android.R stuffs

[Vic Simkus]

Hello

I'm trying to get into Android development and am quite a bit confused
about the android.R constants.  I see them being used in the examples
and tutorials but nothing is ever said about what these constants are,
where they came from and how they relate to the rest of the world.

For example, in the Spinner example project there's this line:

this.mAdapter = ArrayAdapter.createFromResource(this, R.array.Planets,
android.R.layout.simple_spinner_dropdown_item);

What is "simple_spinner_dropdown_item" item?   Why does an "adapter"
of any kind care about "views"?  Etc...

Can someone point me to some sort of in depth documentation.

Thanks
Vic

It is a layout, provided by Android in the firmware. A copy of that
layout can be found in your SDK.

Because that is the complete and entire point behind creating an
ArrayAdapter -- to supply Views to an AdapterView (e.g., rows to a
ListView).

Re: [android-developers] reading file from SDcard

[Mark Murphy]

First, you use Environment.getExternalStorageDirectory() to get at the
root of external storage, rather than hard-wiring in /sdcard (which is
the wrong value, anyway).

Second, you delete the READ_EXTERNAL_STORAGE permission request, since
there is no such permission.

Third, you execute the correct code, as your error message refers to
test.txt, whereas your code refers to test30fps.mp4.

Re: [android-developers] R.java not generated

[Mark Murphy]

If R.java is not being generated, odds are that there is a bug in a
resource or in the manifest that is preventing it from being built.
Look for error markers in Eclipse on those things. You can also try
Project > Clean from the Eclipse main menu.

Widget 1 has android:alignParentTop="true" and
android:layout_height="wrap_content".

Widget 3 has android:alignParentBottom="true" and
android:layout_height="wrap_content".

Widget 2 has android:above pointing to widget 3, android:below
pointing to widget 1, and (AFAIK) whatever android:layout_height you
want (as the above/below rules will override it)

This should work so long as Widget 1 and Widget 3 have knowable
heights (e.g., Button, not ListView) and there is still room on the
screen for Widget 2.

There is only one process, because there is only one application. You

Re: [android-developers] getting the sim phone number

[Mark Murphy]

For devices with a SIM card, getLine1Number() on TelephonyManager
should return that number. However, please bear in mind that a SIM
does not have to have a phone number (getLine1Number() returns null),
and that the SIM might have the wrong phone number. There is no
reliable way from the Android SDK to find out the phone number of the
device, AFAIK.

Couldn't load it on my phone (which now, for some reason, will no longer
allow any apps to be on the sdcard, and it appears that this app insists
on being stored there.)   I did put it on my tablet, and can see where it
would help.  But that shouldn't be necessary---the dev guide clearly
indicates that the Porterduff modes (including ADD) have been supported
in the SDK since API Level 1.  Therefore, it's there...or at least, it's
supposed to be.

I'm completely stumped on this one.

Re: [android-developers] Layouts - Using Remaining Space For Intermediate View

[JTeagle]

>This should work so long as Widget 1 and Widget 3 have knowable
>heights (e.g., Button, not ListView) and there is still room on the
>screen for Widget 2.

Thanks for this. I see where you're going with it, but unfortunately that 
won't help my situation - and that's my fault for not making my example 
clearer. Although I only specified three widgets / views, there could 
potentially be more, and more than one view that would want to grab as much 
space as possible.

Consider the following revised example:

Widget 1 - natural height
Custom View A - largest height possible
Widget 2 - natural height
Custom View B - largest height possible
Widget 3 - natural height
Custom View C - largest height possible
Widget 4 - natural height

Although widgets 1 and 4 could still be aligned to top and bottom, the 
problem now is how to position widgets 2 and 3 (we can't even use 
CENTRE_IN_PARENT now, since view B is in the middle). Since we have three 
views vying for the maximum space they can get, I would want them to each 
grab a third of the remaining space (so equal weight). In other words, the 
way a GridBagLayout would handle it in desktop Java.

I cannot assume the position (order) of any of the widgets or views, since 
I'm trying to build a framework that allows me to add (from a higher layer 
of code) controls of any type in any order, to suit multiple applications, 
without that higher layer having to have knowledge of how that is achieved. 
This mechanism is being translated into other languages / environments such 
as desktop Java, C++ / MFC and C#. The abstracted layer will be [almost] 
directly portable by referring to generic concepts, and this underlying 
layer (unique to each platform) will deal with creating platform-specific 
controls and laying them out as required.

(Controls are being added through code rather than XML, but I realise 
alignments and positions would be equivalent no matter which is used - just 
written differently.)

Do you perhaps know how to reliably measure actual height controls (at what 
point in the code can I get this information - a notification handler?).

If so, can I manually resize the views at a later stage to fit (I assume I 
can, and then simply call requestLayout() )?

Getting the measurements would be an alternative way to solve the problem.

Or am I looking at deriving my own layout manager?

Re: [android-developers] Re: Strange force close on Froyo phone, works fine on ICS tablet

[Mark Murphy]

Create a separate little project that accesses PorterDuff.Mode.ADD.
Run it on the phone. If it crashes the same way, and particularly
given your comment regarding external storage, your phone may be
messed up, somehow. If it does not crash the same way, then you have a
stake in the ground, around which you can start analyzing what is
different between the projects.

You will have to create your own custom ViewGroup for that, AFAIK. And
even then, it assumes an inaccurate definition for "largest height
possible".

If the "higher layer" requests 10,000 widgets, you will not have
enough room on the screen. Perhaps a ScrollView, with everything being
"natural height", is a better approach.

Write your own ViewGroup.

That's what I mean by "write your own ViewGroup". :-)

I was thinking about doing that...I should have.  Ok, here's what
happened, in sequence:

   1) I changed the example from Pro Android Media
  (Ch03 / Choose Picture - Composite) to use ADD instead of
  MULTIPLY.  This project is built for Android 2.2, period.

   2) Eclipse griped...no such mode.  Change to .
   3) So I added the two imports that Eclipse whined about not
  being used in my app:  android.graphics.PorterDuff, and
  a.g.P.Mode.  Suddenly ADD is supported (and this is ALL
  documented in the developers guide as being supported
  since API level 1, with the 3 imports---the previous 2,
  plus android.graphics.PorterDuffXferMode)
   4) Eclipse shut up, and built the APK.
   5) It works.

But here comes the mystery again:  the example from the book is what
I built my code from...different variables, ADD instead of MULTIPLY,
but otherwise the same few lines of code.

Hmmm  PorterDuffXferMode does NOT have ADD, whereas the other two
do.  The error I'm getting is listed as only happening when you have
(I forget the exact wording, but basically, conflicting classes).   Or
not.  I was thinking PorterDuffXferMode conflicted with the other two,
but without it, the user of PorterDuffXferMode is an error.

Sigh.  :-(

[android-developers] Re: reading file from SDcard

It is not quite as simple as that. Many Android devices have several
kinds of external memory.  There is the truly removable kind like a
physical SD or micro SD card.  Then there is built-in external memory
that cannot be removed, but in every other respect it acts like
external memory, especially in the relaxation of security requirements
for access.  That is, an application can write to the root of external
memory (of whatever kind) but it cannot write to the root of internal
memory.

It has been my experience that
Environment.getExternalStorageDirectory() which you mentioned
generally points to the built-in kind of external memory.  So if you
want to access the real removable SD card file system there is no way
I know of other than hard-wiring the actual path name, or letting the
user enter it on a form (assuming the user even knows what the path
name is).  For example, on the Acer Iconia Tablet A-100 there is

  /mnt/sdcard (built-in "external" memory")
  /mnt/external_sd  (removable SD card)

But Environment.getExternalStorageDirectory() returns "/mnt/sdcard".

It points to whatever the device manufacturer chose to point it to. On
some devices, it is removable; on some devices, it is not.

Or not using it.

Or waiting for the Android SDK to support multiple "external" mount points.

Or waiting for somebody to crowdsource a database of available
standard mount points and their accessibility (just because /mnt/foo
exists does not mean you can read or write to it, or that the user can
access it), and waiting for somebody to create some sort of JAR that
leverages this crowdsourced database, so you can determine the
available options for your hardware to present to the user.

You will note that neither of these is /sdcard, which was my point to the OP.

[android-developers] values-v9 and styles.xml problem

[Put_tiMe]

This documentation 
here: 
http://developer.android.com/guide/topics/ui/notifiers/notifications.html#CustomExpandedView

*Says:*

Then, to apply the system's default colors for notifications on Android 2.3 
and higher, use the following styles for res/values-v9/styles.xml:








I'm using* android 2.2* for dev.

But if I do the above, then I get this error:
error: Error retrieving parent for item: No resource found that matches the 
given name 'android:TextAppearance.StatusBar.EventContent'.


Any idea as to how to do this?


Thanks

[android-developers] Re: Native Maps Api - zoom to geocode returned viewport

[Simon Giddings]

So the answer is to use the MapController.zoomToSpan(...) method.
Further information can be found here : 
Getting map zoom level for given bounds on Android like on JS Google Maps 
API: 
map.getBoundsZoomLevel(bounds)

 (Please put a more informative title in the subject line)
 If you mean native arrays, they work exactly the same. Are you having 
trouble compiling some code? If so, please post a sample of code and show 
us the compiler error you are getting.

[android-developers] Debugging code that cause's a hardware restart of the phone :?

[ThomasWrobel]

I am working on a fairly complex application. When debugging it over
the last few days it occasionally cause's a hardware restart of the
phone.
I am debugging it on a real phone over usb (Windows/Eclipse for my
development).

However, I cant seem to figure out what's causing these crashs because
nothing appears in the LogCat - the restart clears it, and while I can
read for a few seconds whats there before it does that I cant see
anything that looks like it would cause a crash - it all seems
"business as normal".

It seems like whatever causes the crash stops the LogCat messages
being reported, including those related to the crash.

Thing is, I haven't a clear how to go about debugging this :-/
Any ideas ?
