[android-developers] Re: Camera access

[kypriakos]

Just in case this will help anyone else - i figured out the issue. I
was snapping
a picture and then restarting the preview right away. With the slower
phones (G1)
this was ok but with newer phones that are faster this won't work. I
moved the
preview to start inside the jpegcallback and after the picture was
stored and
it works fine now.

Thanks

[android-developers] Help needed with dynamic layout change [UI Rearrange]

[androidCrazy]

I have two activities. 

The first activity has buttons arranged as per layoutfirst.xml in protrait 
mode and layoutfirst.xml in landscape mode, placed in layouts-land folder.
The second activity is a text view.

The navigation first view -> button click -> second view
Change orientation to landscape in second view -> click on back -> comes to 
first view with deformed layoutfirst.xml of the portrait orientation. I 
want that to be changed to layoutfirst.xml in the layouts-land folder. To 
achieve this, in onStart() method of the first view, called 
"setContentView(R.layout.layoutfirst);", the layout was changed accordingly 
but the screen freezes.

Is there anything I'm missing or any other way to achieve this. Any help is 
greatly appreciated. Thanks in advance.

[android-developers] Re: Camera access

[kypriakos]

Well this is what I found out -

first time the activity is launched the camera goes into preview mode,
snaps a pic,
stores the pic and then tries to get into preview mode again. I
removed the last
step and still the pic is taken and it stays stuck on the screen. I
realized that
the camera service usually will ask the user if he/she wants to save
the pic. Either
way it then returns to the preview mode. In the case of my app it is
supposed to snap
the pic, save it and return to preview. This exact code works on teh
G1 but on the
LG after the pic is snapped it remains on the screen.

Would the camera service be different across Froyo-based mobiles? I
wouldn't thjnk

Re: [android-developers] MediaMetadataRetriever does this work PLEASE Help?

[New Developer]

So my play loop is

loadFrame()   {
   frames.incrementProgressBy(326-(playSpeed*30)); frames is a seekbar
   frame = frames.getProgress();
   pict = retriever.getFrameAtTime(frame*1000);
   mBitmap  = Bitmap.createBitmap(pict, 0, 0, 1060,600, matrix, 
false);

   super.setImageBitmap(mBitmap);
}

@Override protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (isPlaying)  loadFrame();
}

so essentially  frame is incremented by 326
thus  getFrame  is in steps of  326,000

I think this is generating the jumpiness I see,
But if I make this any smaller it will play slower than what was recorded.
the 326 allows a 15 second video to play back in 15 seconds.

So is there anyway to speed up the time it takes to recall loadFrame()  
thus allowing for a smaller step value ?



Thanks in advance

isHardwareAccelerated   returns false  even after

No Joy

Please any advice on how to get these bitmaps to show ? ? ?

Main Activity   has  a FrameLayout
the FrameLayout is fille with a call to a Fragment  inflate
The fragment extends an ImageView Type

I have tried setting the layer type  to  Hardware accelerated  will 
not work
isHardwareAccelerated   returns false  even after  
layout.setLayerType(View.LAYER_TYPE_HARDWARE,  null);



tried to use runOnUiThread
   mActivity.runOnUiThread(new Runnable() {
public void run() {
mBitmap.prepareToDraw();
ImageDisplay.imageView.setImageBitmap(mBitmap);
ImageDisplay.imageView.invalidate();
}
});

No Joy

Please any advice on how to get these bitmaps to show ? ? ?

Main Activity   has  a FrameLayout
the FrameLayout is fille with a call to a Fragment  inflate
The fragment extends an ImageView Type
Works great with jpg  and png will not work with  3gp

Thanks again

[android-developers] Re: 1024x1024 texture drops framerate dramatically

It's only 3 years old, but I suppose that anything older than 6 months

Anyway, I don't use it as a phone; I use it as a development tool.

[android-developers] Call tab_indicator.xml from styles.xml

[Ivan Soto]

Hello,

I'm trying to create a custom theme without relying in classes. Something 
that is easy enough to plug into an app. My problem is that the TabWidget 
in styles.xml doesn't reference tab_indicator.xml anywhere so I can't see a 
way of using a custom style unless I call the style from the layout file or 
the activity using the tab widget.

This is the only reference I see in styles.xml


@style/TextAppearance.Widget.TabWidget
marquee
true


Any ideas?

[android-developers] SharedPreferences question

[Larry/MavrickProductions]

I have a need to store a single value - the year - so that it can be
called from any activity in my app. Shared Preferences seems to be the
easiest but I've got myself coded into a wall and could use a spot of
advice.

I think the problem is in my XML, but I'm not sure. Here's the
pertinent snip of the java. It should be calling the "setyear"
variable from the settings.xml file:

SharedPreferences myPrefs = getSharedPreferences("settings",
MODE_PRIVATE);
final SharedPreferences.Editor prefsEditor = 
myPrefs.edit();

int checkme = myPrefs.getInt("setyear", 0);
if (checkme < 2011)
{
prefsEditor.putInt("setyear", 2011);
prefsEditor.commit();
}

and the XML:


http://schemas.android.com/apk/res/android";
  >

android:key="setyear"
android:defaultValue="2011"


android:key="currlist"
android:defaultValue="99"



Suggestions? Did I totally hose myself?

Best, -Larry

[android-developers] Help with GPS Provider Switch

[Tommy Hartz]

 

Hey,

 

Right now when trying to get a user location I start with the GPS Provider.
I have a timer set for 30 seconds, If a location is not found in 30 seconds
the timer goes off and stops that location request. When that happens I move
to the Passive Provider. After 30 seconds if a location is not found I stop
the location request and move to the Network Provider.

 

My issue is that when the network provider gets called it never does
anything. If I start with the network provider it goes off just fine and
returns a location back to me. Below is the code I am trying to use:

 

gpsTimer.schedule(new TimerTask(){

  @Override

  public void run() {



startPassive();





  }

}, 3);



currentTimer = "GPS";

 
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
locationListener);

 

private void startPassive(){



locationManager.removeUpdates(locationListener);



//Now we want to try for a Passive Fix

currentTimer = "Passive";

passiveTimer.schedule(new TimerTask(){

 

  @Override

  public void run() {

startNetwork();

  }

  

}, 3);

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0,
0, locationListener);

 

private void startNetwork(){

locationManager.removeUpdates(locationListener);

currentTimer = "Network";

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0,
0, locationListener);

 

any help or suggestions would be greatly appreciated. Thank so much in
advance.

[android-developers] Re: DatePicker in a fragment

[kbeal10]

The solution I came up with was to subclass DialogFragment, returning
a DatePickerDialog in onCreate()

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

return new DatePickerDialog(sContext, dateSetListener,
sDate.get(Calendar.YEAR), sDate.get(Calendar.MONTH),
sDate.get(Calendar.DAY_OF_MONTH));

}

I implement DatePickerDialog.OnDateSetListener.onDateSet() in my
DateDialogFragment.

private DatePickerDialog.OnDateSetListener dateSetListener =
new DatePickerDialog.OnDateSetListener() {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {

Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
//call back to the DateDialogFragment listener
sListener.dateDialogFragmentDateSet(newDate);

}
};


I also define a listener interface in my DateDialogFragment for the
calling Activity/Fragment to implement.

public interface DateDialogFragmentListener{
public void dateDialogFragmentDateSet(Calendar date);
}

As you can see above, I fire my DateDialogFragmentListener from the
DatePickerDialog's listener.

I wrote about it in more detail with entire source here:

my experience in this situation is to write some one-off and run it

otherwise one may propagate mythology ... not good in real world

Correct. Content providers for inter-app data sharing can work well
when there is a clear hierarchy (e.g., app plus plugins, where the
plugins have no meaning outside the app), or where the content
provider is not essential (so if the provider does not exist, an app
still has utility, just lacking some optional feature(s)).

> Do all devices have external storage for instance

Yes. It is occasionally unavailable on Android 1.x and 2.x -- if it is
mounted as a drive on a host PC, it is unavailable to apps. This is
not a problem on Android 3.x and 4.x, due to some changes in the way
devices share files with the host PC.

http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

> also
> can databases be created and managed in external storage?

Yes. I have not tried accessing the same SQLite database from multiple
processes via external storage. In principle it should work, as Rails
uses SQLite across processes that way, though I don't know if the
peculiarities of external storage (e.g., FAT32 on Android 1.x and 2.x)
will pose any problems.

However, as Kristopher suggested, it is unclear whether it is in your
best interests to make this be multiple apps. For example, if your
objective is to get paid multiple times, have one app and use in-app
purchasing to unlock the additional features.

[android-developers] Re: Multiple Apps and Content Providers, How to ?

[swebb99]

Thanks for the reply Mark. As you say contacts is part of the eco
system and hence I can see the benefit of a provider. But I'm failing
to see how providers created by normals developers like myself are
actually that useful unless you have one app that provides the
provider and then the others make use of it, the problem with this is
you need to make sure that the customer always purchases the app with
the provider first!!!

So from what you say using external storage is a possibility. What are
the pitfalls of this, I must admit I don't know anything about the
relationship between android and external storage and the pro's and
con's of this. Do all devices have external storage for instance also
can databases be created and managed in external storage?

Thanks

Steve

[android-developers] Re: How to read data off a website into an Android app

[mellery451]

well, you're not going to be able to (easily) read Excel files on
android (xls, or whatever they are called these days), but csv will
probably work - perhaps that's what you were thinking of anyhow. Have
a look at 
http://groups.google.com/group/android-developers/browse_thread/thread/cec5eb668e3293fe
for discussion about loading csv. Once you've fetched the file using
the http client, opencsv should be able to parse/load it.

Contacts is part of the operating system. Your apps are not, unless
you roll your own firmware and put your apps in it.

Outside of putting content on external storage (which wouldn't need a
content provider), you cannot readily share information between
multiple apps such that any of those apps could be removed without
issue. You could arrange for *all* the apps to each have their own
copy of the data, I suppose, though that would require N times the
storage space for N apps.

[android-developers] Re: How to read data off a website into an Android app

[Jungle Jim]

Thanks Alexander and Mike.

One more question: I also want to be able to put some data (perhaps in
Excel spreadsheet format, but not restricted to that) somewhere on the
web and have my app read that data. This way I can periodically revise
the data that shows on the apps that my customers have installed on
their phones.

Any ideas on the best way to do that?

Re: [android-developers] Re: getResourceAsStream and resource matching.

[Dianne Hackborn]

Oh wait, you are using the Java resource stuff?  Don't.  You must always
use Android's APIs (in particular android.content.res.Resources) to access
Android resources.

[android-developers] Re: Camera access

[kypriakos]

Right on Mark, One of the reasons I found out was a lingering process
that was locked it.
I killed that process and the camera service responds fine now.

The second time it did this I found out that after the camera goes
into preview, an image
is snapped (this is the app I am testing that takes pictures
automatically every few
seconds) but right after the first picture is snapped on this phone
the Camera service dies.
This is still puzzling cause like I said earlier this app works fine
on an identical phone.
I will check to see if I am setting the resolution of the preview or
the picture to be something
outside what this camera can handle? Also I saw messages that the
Rolloff feature is not
supported, no idea what that is.
When I set the autofocus in the manifest the phone (again running 2.2)
said that this feature
is not available, which makes no sense since 2.2 does support
autofocus.

Re: [android-developers] Camera access

[Mark Murphy]

It seems like the CameraService thinks that the camera is in use. Only
one application can use the camera at a time. And if an application
leaks the camera (by not closing it), it might be tied up until the
process gets terminated or you reboot the phone.

[android-developers] Re: Android Development Environment?

[joebowbeer]

The NetBeans plugin (nbandroid.org) has the most stable support for
the new Android SDK Tools (r14+). The support is a fairly thin wrapper
on the Ant build script and properties files, but it seems to work,
which is more than I can say for the current state of Eclipse with ADT
15.

IntelliJ IDEA is not yet supporting the newest Android SDK Tools.

[android-developers] Camera access

[kypriakos]

Hi all,

I have been running an activity that access the phone's camera (on
Froyo), puts it
in preview mode and then snaps and stores a picture. This has been
working fine
on one phone but on a second phone with the same OS and specs I get
the following:

I/#LGIME  ( 1481):  onStartInput: restarting=false, fieldId=-1
I/System.out( 6895): surface created - calling picture ...
E/CameraService( 1291): CameraService::connect X (pid 6895, new client
0x1bfc8) rejected. (old pid 5261, old client 0x22798)
E/CameraService( 1291): forcefully terminating old client.. ref count

Has anyone seen this before? What would cause the camera service to
reject connections to
it since the Manifest for the app is the same as on the other phone
and it does allow Camera
access. Any ideas would be appreciated.

Thanks

[android-developers] Re: How to read data off a website into an Android app

[mellery451]

well, I think you'd want to start with an HttpClient (http://
developer.android.com/reference/android/net/http/
AndroidHttpClient.html) to make the request and download the
resource(s). Then you would need to extract the information you need
from the content. This is commonly called "scraping" since you are
trying to extract data from presentation views. It's hairy, and likely
to involve any number of parsers or (gads!) regular expressions to
accomplish the task. I'd avoid this route if at all possible.

If the service you are accessing actually intends for other
applications to consume it, perhaps there is already a public API
(e.g. twitter, facebook, etc. all have http APIs you can use). At the
very least, perhaps the site supports alternative formats for the
content - like xml or json. If requesting a different format is an
option, you'll have a much easier time extracting the data since you
can use a standard parser.

[android-developers] Announcement: Android MIT Kerberos Port with CyaSSL Embedded SSL

[Chris C.]

 

Hi,

yaSSL would like to announce the availability of the MIT Kerberos libraries 
on Android and get feedback from the android-developers group.  Previously, 
the Android platform has been void of Kerberos support - forcing Android 
developers who are either creating new applications or porting existing 
projects to either modify existing code or exclude Kerberos functionality 
from their apps and libraries.

yaSSL has taken the first steps in bringing Kerberos to the Android 
platform.  The native MIT Kerberos libraries have been cross-compiled for 
Android and are now able to be used natively with the Android NDK.  yaSSL 
has added the CyaSSL embedded SSL library's cryptography library 
(CTaoCrypt) as a crypto implementation for Kerberos, allowing embedded 
projects to use CyaSSL's lightweight and fully functional crypto backend on 
Android.

In addition to the cross-compiled MIT Kerberos libraries, yaSSL has created 
a sample Android NDK application wrapping the functionality of kinit, 
klist, kvno, and kdestroy with a simple GUI front-end.  We hope this 
application provides a starting place for application developers interested 
in using Kerberos on Android.

The MIT Kerberos libraries and sample application are distributed under the 
MIT license (using CyaSSL's FLOSS exception) and the code will be in the 
MIT Kerberos code repository in the near future.  Until it has been merged 
into the MIT repositories, you can find the sample application on GitHub at 
the following URL.  The sample application includes cross-compiled Kerberos 
and CyaSSL libraries.  Instructions on cross compiling MIT Kerberos 
yourself will be released in the near future.

https://github.com/cconlon/kerberos-android-ndk

Our next step is to work on adding Java bindings for the native Kerberos 
GSS-API library on Android.  As we have looked into several methods of 
accomplishing this, we would like to hear what the community would like to 
see in the Java bindings.  Also, we would like to explore if there are any 
existing solutions which could be of use.  The options we have looked at 
thus far include:


   - Porting over an existing org.ietf.jgss Java package to Android and 
   tying that into the native GSS-API library through JNI.
   - Using SWIG to generate Java wrappers to the native GSS-API.

Are you interested in using Kerberos on Android?  What do you think the 
best path would be for adding Java bindings?  Do you have any suggestions 
about the direction of the project so far?  If so, please let us know your 
thoughts at info (at) yassl.com.

Thanks!

Team yaSSL

[android-developers] AsyncTask must be invoked on the UI thread

[BelvCompSvs]

given what I have read so far it is much simpler for me to base-class
on AsyncTask and do the threading from my sources but docs state
constructor "Runs on the UI thread before doInBackground(Params...)."

I can figure out the Handler(s) to process messages delivered from the
UI thread ~ since I do not have access to a reference compliant
sources there is no way for me to know using only the docs at /
reference/android/os/AsyncTask if I need to call super.onPreExecute()
from an override to arrive at stable application state across most
vendor platforms

[android-developers] Help with GPS Provider Switch

[Tommy Hartz]

Hey,

 

Right now when trying to get a user location I start with the GPS Provider.
I have a timer set for 30 seconds, If a location is not found in 30 seconds
the timer goes off and stops that location request. When that happens I move
to the Passive Provider. After 30 seconds if a location is not found I stop
the location request and move to the Network Provider.

 

My issue is that when the network provider gets called it never does
anything. If I start with the network provider it goes off just fine and
returns a location back to me. Below is the code I am trying to use:

 

gpsTimer.schedule(new TimerTask(){

  @Override

  public void run() {



startPassive();





  }

}, 3);



currentTimer = "GPS";

 
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
locationListener);

 

private void startPassive(){



locationManager.removeUpdates(locationListener);



//Now we want to try for a Passive Fix

currentTimer = "Passive";

passiveTimer.schedule(new TimerTask(){

 

  @Override

  public void run() {

startNetwork();

  }

  

}, 3);

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0,
0, locationListener);

 

private void startNetwork(){

locationManager.removeUpdates(locationListener);

currentTimer = "Network";

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0,
0, locationListener);

 

any help or suggestions would be greatly appreciated. Thank so much in
advance.

[android-developers] Re: NDK GetMethodID problem

[a1]

Signature should be "(II)Landroid/graphics/Bitmap;" colon is used as class 
name string terminator not as type list separator (types in signatures are 
single uppercase letters, except of classes which are represented by 
L; where colon is terminator)

[android-developers] TabWidget NullPointerException in pre-Froyo

[Pinheiro]

Hi!
I've done a simple TabActivity that loads several Intents into the
tabs. It works fine in Froyo or later but gives this error on older
versions:

E/AndroidRuntime( 1958): java.lang.NullPointerException
E/AndroidRuntime( 1958):at
android.widget.TabWidget.dispatchDraw(TabWidget.java:173)

This happens even with an empty OnCreate method:

public class MyTabHost extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.mycustomtab);
   }

mycustomtab.xml:

I did a quick search and found other developers with the same problem
but it seems no-one has found a solution to this problem (possible bug
in Android?).
Can anyone help? Thanks in advance!

If you are running on Honeycomb, you need to also include "screenSize" 
(which was introduced in Honeycomb) along with "orientation". See

[android-developers] Remote control of apps

[kypriakos]

Hi all,

I remember that you can launch apps remotely on a phone using:

adb shell am start -n ...

I never looked for one that would terminate the app remotely. Is there
one? May be I can write scripts that can grep the ps on the device
and send a remote kill but (i) that is not possible on devices that
are not rooted and (ii) may be not a good idea. So most likely I will
have to write a receptor on an app that when a term app commands
comes in over a socket it can then schedule itself with Android
for termination.

Has anyone tried this before?

Thanks

[android-developers] PopupWindow with custom view for Spinner breaks touch events?

[Jona]

I'm not understanding what exactly is the issue with my custom
PopupWindow. I have a ListView as my content view and each item in the
list contains a button or Spinner.

When I place a spinner with a custom layout for its list items none of
the buttons or Spinners work, nothing happens when pressed, on my
content view list... But if I leave the default android layout for the
spinner there is no problem...

What exactly could I be missing?

Re: [android-developers] get and set data from autocomplete

[Nicolás Mariano Obregón]

I dont's know if that's possible but I would advise you to create a
Map and when the user clicks on an
item from the dropdown list you look for it in your map. In order to do
this you should implement OnItemClickedListener for your
AutoCompleteTextView.

Hope this works for you...

Re: [android-developers] calviling webservice

[Nicolás Mariano Obregón]

Hi jaggu, first of all, to consume a WebService you need the *Ksoap2 *library.
After you get it just check for a simple tutorial on how to use it and
that's it. It's quite easy.

A personal recommendation, use serialization tools like *xstream *to send
and receive java objects serialized as xml instead of using KVMSerializable
interface because it sucks!

I hope this works for you.

[android-developers] NDK GetMethodID problem

[Peter Staab]

Hello,

I am getting the following error:
>11-15 19:31:57.898: D/dalvikvm(5046): GetMethodID: method not found: 
>;.createBitmapRGBA:(I;I)Landroid/graphics/Bitmap;

with this code:
java:
public Bitmap createBitmapRGBA(int w, int h) {
return Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_);
}

cpp:
msgId = env->GetMethodID(clazz, "createBitmapRGBA", "(I;I)Landroid/
graphics/Bitmap;");

When I replace the arguements of "createBitmapRGBA", for instance to:
java:
public Bitmap createBitmapRGBA(String dummy) {
return null;
}

cpp:
msgId = env->GetMethodID(clazz, "createBitmapRGBA", "(Ljava/lang/
String;)Landroid/graphics/Bitmap;");

then everything works fine. So, I suspect that there is something
wrong with "int w, int h" resp. "(I;I"), but what's wrong with this?

Regards,

[android-developers] Re: determine finish of the process addView (View child)

I found a workaround.
1. Be sure that when you create the spinners dynamically (not by xml,
but by code), that you assign an ID to the spinner.
2. Set a Global Variable in your class:
private HashSet spinnersEnabledForOnItemSelected = new
HashSet();

3. Whenn you create your Spinners overwrite the Method onClick
Spinner spinner = new Spinner(parentActivity){
  @Override
  public void onClick(DialogInterface dialog, int which) {
  // This Method is only called, when the Spinner is "open",
  // I mean when you see all the Items of the spinner, after clicking
  // on an Item
spinnersEnabledForOnItemSelected.add(this.getId());
super.onClick(dialog, which);
  }
};


4. inside the OnItemSelectedListener inside the Method onItemSelected
you check if minimum one click happened
onItemSelected(AdapterView arg0, View aSelectedTextView, int
position, long idOfTheSelectedTextView) {
  Spinner spinner = (Spinner)arg0;
  int id = spinner.getId();
  if (! spinnersEnabledForOnItemSelected.contains(id)){
return;
  }
  // additional code here...
}

5. before you add a spinner to your parentview or linearlayout

spinnersEnabledForOnItemSelected.remove(aSpinner.getId());
yourParentLinearLayout.addView(aSpinner);

--> now it is guaranteed that the procedures inside the Method
onItemSelected are getting only processed after the first click or
touch by the user

I am happy when I get some other or better solutions to clean up my
brain :-)

[android-developers] Android C2DM question

[Neilz]

Hi all, I'm currently weighing up the options for push notifications
in my app.

1) Polling. I could use a boot receiver / alarm manager combination to
fire off a process which checks our server periodically, say every 15
minutes, and then immediately terminates. First question is, is this
resource hungry? I can't believe it would make any noticeable
difference...

2) Urban Airship. I'm put off using this as their site says it doesn't
work if the app is mounted on the external storage. As our app is
likely to contain significant (many megabytes of) assets, this
probably isn't the best option.

3) C2DM. Can anyone confirm if this works when the app is stored on
the SD Card? I'm just curious, as even though Urban Airship uses the
C2DM protocol to send the notifications, it isn't able to in this
instance.

Thanks for any advice.

[android-developers] Re: More traditional Android menu

[alexb]

First, zip files are harmless, unless you automatically invoke some
executables from it, which I think developers do not do.
The link points to the complete Eclipse project with two classes,
MenuDialog - the menu itself and MenuDialogDmo - the main activity
one.
MenuDialog allows you to access menu as a list, each item can have an
icon and there can be a picture for the whole menu, like a logo.
You may want to take a look here:

[android-developers] Difference between signed and unsigned response in in-app purchase

[santhosh kumar]

Hi,

I am getting unencrypted JSON string and signature as response from
Market after purchased product. But I am unable to understand
difference between signed and unsigned response. But in the in-app
documentation they mentioned for developer account without drafting
application in market, we will get signed data as response.

Table 1. Conditions under which static responses are signed.
"http://developer.android.com/guide/market/billing/
billing_testing.html"

But in my case I am always getting unencrypted JSON string and
signature.

Could any body help me for understanding signed and unsigned response.

Thanks,
Santhosh

[android-developers] determine finish of the process addView (View child)

[Anil from the Alps]

I have a LinearLayout, lets call it LL; in my code I dynamically
create spinners and and/remove them from LL; every Spinner has a
AdapterView.OnItemSelectedListener with the Method onItemSelected;
when you add a Spinner dynamically then the Method "onItemSelected" is
called automatically; this behavior is not programmed by me, it's
automatically invoked 1 time; when the view is restored from a State
before, it seems to get invoked 2 times before the user has done
anything;

inside the Method "onItemSelected" I have to take care if the
selection comes from the User or if it comes from initialization (or
adding) the spinner on the screen; now I played a little bit with the
method

LinearLayout.addView(mySpinner)

# My Idea was the following:

boolean ignoreNextSelections = true;
LinearLayout.addView(mySpinner)
ignoreNextSelections = false;

The boolean Variable ignoreNextSelections I could check inside the
Method onItemSelected. But this idea doesn't work because the Method
LinearLayout.addView(View child) seems to be nonblocking, it seems to
be a Thread or something similar in the background.

So now my question:
Is there a Method to determine if a spinner is fully added to the
screen (or to a view)?
Or in other words:
Is there a Method to determine if the layout-process of a View is
fully finished?
Thanks for Help
Anil

[android-developers] Why is the activity being destroyed/recreated (NOT a configuration change)?

[dwass]

Sometimes we are seeing the following behaviour:

- Activity A is launched
- Activity A starts Activity B
- Activity B is used for a while, it can be a few minutes or a few
hours
- Activity B finishes
- Activity A is then destroyed and recreated

Why is Activity A being destroyed and recreated, instead of just being
restarted (call to onRestart(), onStart(), onResume())? I could
understand it if ActivityA had been destroyed some time ago, but what
we see from the logs is that AFTER ActivityB.onPause() gets called,
ActivityA.onDestroy() is called and then a new instance of ActivityA
is created.

This isn't due to an device orientation change, as the manifest for
both activities contains android:screenOrientation="nosensor" and we
can't reproduce the behaviour by changing the device orientation.

The problem isn't reproducible, but we get logs from users where we
can see this behaviour, so we know it is happening.

Anyone have an idea why this is happening? This doesn't happen all the
time, just occasionally. The usual behaviour is the expected behaviour
(ActivityA just gets resumed).

Thanks,
-DWass

[android-developers] Re: Honeycomb: disabled menu items look

[port443]

I'm loading images myself from an APK loaded via ClassLoader, so I
seem not having access to Resources class.

So, I tried building StateListDrawable on the fly: this seems to work
(two files instead of three!).

Yes, icons required for different menu styles should be different, but
our graphics designer made 32x32px images which look good on both old-
style and new-style menus (Moto XOOM; mdpi).

[android-developers] empty Cursor after Context.deleteDatabase and data re-added

[Hank]

I implemented a logout function in my application that removes the
user's account, shared preferences, and deletes the database using
context.deleteDatabase(). But after I re-login, and the data is re-
added, when I go into one of my activities using a
SimpleCursorAdapter, I notice that the list is not being populated. I
check the cursor being returned in that class and it has a count of 0,
so no rows are being returned. I also checked in my onPerformSync()
function in my SyncAdapter(), where the data is being re-added, and
the data seems to be re-added to the database. What could be the
problem?

[android-developers] Gravity "virtual" sensor source code

[markus]

Hi all!

Now that Ice Cream Sandwich is out, I thought I'd have a look at how
the "virtual" sensors have their data calculated, in particular
TYPE_GRAVITY. Of course it will involve data from some or all of the
real sensors (accelerometer, gyroscope, and magnetic field), but I've
read somewhere (can't find where just now) that from Android 4 ICS,
the virtual sensors, and TYPE_GRAVITY in particular, will be more
accurate, because they involve the gyroscope, if it's available in the
phone.

I've got the Android 4 source code downloaded, but I can't find the
place where this data is calculated. It's not in the Java code, as far
as I can tell, so it must be in native code somewhere. I'm new to
looking at the Android source code, so maybe someone could point me in
the right direction?

Thank you very much!

Regards,
Markus

Disable the default ones and replace with your own.

I want to repoduce zoom button from new google maps.


Why? They'll just change again down the line at some point, so you're
giving yourself more maintenance work, if your plan is to be consistent
with that app. Personally I hate the "flat" style they're going with in
Maps and all the Google products now. You should aim for consistency within
your own application.

[android-developers] How to transform a openGL object into a bitmap?

[saex]

Actually i have a GLSurfaceView witha square that can be rotated and
zoomed, and this square haves a texture.

I need that a function to transform the current square into a bitmap.
For example, if the square is rotated, the bitmap must be the square
rotated as the user can see it on the screen

it is possible?

[android-developers] Multiple Apps and Content Providers, How to ?

[swebb99]

Hi,

Newbie here.

If I want to create several apps which all allow a user to created,
read, update and delete related data so a content provider would seem
to be the way to go. However I don't know which app a customer would
buy first, second and so on. So how do I make sure that:

1) The first app creates and registers the provider.
2) Subsequent apps only make use of the provider and don't recreate.
3) Make sure the provider gets upgraded if a new app is bought, but
also is not downgraded if an older app is bought after a new one.

>From reading the docs on content providers I just can see how any of
this is possible. The definition of providers doesn't seem flexible
enough to allow this kind of thing. If it isn't possible what is the
strategy because it looks like content providers are the only
mechanism for applications to share data.

Thanks

Steve

[Tomasz Gawel]

There is strange bug, whenever I send a post to Android Developers
Group it happens to be crossposted to "exotic" groups like "fametest"
"No 1" or "flutuberwachung" which I have nothing to do with.
When I send post to other groups ont google the proble does not occur.

Only if you write your own firmware. You cannot use custom widgets in
app widgets.

[android-developers] Camera Error 100, ICamera died

[saex]

When i make a photo, after the photo is stored, i want that the camera
preview is still on the screen, but something is going wrong, because
after making a photo the camera preview frozens and i get this error:
Camera Error 100, ICamera died

I checked some stackoverflow questions about this error but none of
them help me, i dont know what i am doing bad.

this is the code of my custom camera view class:

public class CustomCameraView extends SurfaceView
{
static final int FOTO_MODE = 0;
SurfaceHolder previewHolder;
Camera camera;
Context myContext;
boolean mPreviewRunning = false;

   previewHolder = this.getHolder();
 
previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
   previewHolder.addCallback(surfaceHolderListener);
   this.requestFocus(); //necessary to manage camera button
events
   this.setFocusableInTouchMode(true); //necessary to manage
camera button events
}
SurfaceHolder.Callback surfaceHolderListener = new

preview is
not running
camera.stopPreview();
}

p.setPreviewSize(w, h);
//p.setPictureSize(1024, 768);
camera.setParameters(p);

mPreviewRunning = true;
}

camera.stopPreview();
mPreviewRunning = false;
camera.setPreviewCallback(null);
camera.release();
camera=null;
}
};

if (imageData != null) {

[android-developers] ImageView with ScaleType.FIT_XY programmatically

[B.Arunkumar]

Hi,

I have a problem. I have created a relativelayout with imageview
in my code like this:-

RelativeLayout relativelayout1 = new RelativeLayout(this);
RelativeLayout.LayoutParams r1 = new
RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
relativelayout1.setLayoutParams(r1);

ImageView view = new ImageView (this);
view.setScaleType(ScaleType.FIT_XY);

BItmap bitmap =
BitmapFactory.decodeResource(getResources(),R.drawable.texture);

RelativeLayout.LayoutParams r6 = new
RelativeLayout.LayoutParams(640,640);
r6.setMargins(0, 160, 0, 0);
view.setLayoutParams(r6);
view.setImageBitmap(bitmap);

But the imageview simply does not extend beyond the screen dimensions
of 320 * 480. Why is this happening and how can I solve this problem?
I want the imageview width and height extended beyond the screen
dimensions. How do I do it programmatically?

Thank you,
B.Arunkumar
