[android-beginners] Re: Application closes when I try to convert String to Integer

[Naveen Krishna Ch]

Try a code similar to this,

EditText priority =
(EditText)myAlertDialog.findViewById(R.id.priority_edit);
int x = Integer.parseInt(priority.getText().toString());

This works fine for me..

[android-beginners] RampUp the binding b/w Activity & Service

[Naveen Krishna Ch]

Hi all,

I am looking for a mechanism to ramp up the binding between
Activity and a Service.

*I have a:
*I have a java library wrapping up the service, Which does the binding.
*Looking for:
*A way to have a worker thread (Looper, etc ) to process the bindService
call and give a callback to onServiceConnected();

As fast as the instantiation of the class would take,

Is this approach worth giving a try.  If so, Can any one guide me to make
 this approach work.

Any suggestions would be helpful..

Use PlatforLibrary's Manifest file as reference.
or
create new file named as AndroidManifest.xml in ur project head folder and
Eclipse helps u to write AndroidManifest.xml with some facilities in

Have a javaclass,

U need to have a JNI layer in between so that java can call ur  c functions.

So wrape ur c fiels with a jni layer, build another shared library.
use System.loadLibrary("libraryname");
to load that,
and then in java u can call these methods.

If u have ApiDemos apk, run it on emulator, go into
view-> layouts-> TableLayout
There the various examples of table layouts are given.
U can find the sources of the same in the apidemo in samples..
Hope it helps

[android-beginners] Re: Help with Services

[Sujay Krishna Suresh]

Hi hamy,
thnx a lot for ur reply... i'm actually workin with SDK 1.0
r2...
since it does not contain the picasa api, i downloaded Google's picasa
uploader app from the market.
it actually integrates itself with the camera app & pictures app in the
share option...
i got the name of the activity from logcat o/p... so no docs... but i'm
having a very bad solution...
this is all i could come up with by researching with the service using the
logcat o/p...
plz chk this n temme if there's a shortcut...
 new Thread() {
  @Override
  public void run() {
  ActivityManager a = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
  boolean flag = true;
  boolean uploading = false;
  while (flag) {
  flag = false;
  List servicesInfo = a.getRunningServices(15);
  for (RunningServiceInfo ele : servicesInfo) {
  if (ele.process.equals("com.google.android.apps.uploader")) {
  if(ele.started){
  uploading = true;
  flag = true;
  } else{
  uploading = false;
  }
  }
  }
  }
  if(uploading){
   // upload successful
  }else{
   // upload failed
}
  }
  }.start();

[android-beginners] Re: Getting Android Error - Unknown URI: content://media/external/images/media

[Sujay Krishna Suresh]

hv u mounted an sdcard image??? if not the external uri wont work...
u can do this by adding emulator option -sdcard  in ur
android preferences...
to make the sdcard image use the command mksdcard command in ur sdk tools...
mksdcard: create a blank FAT32 image to be used with the Android emulator
usage: mksdcard [-l label]  

  if  is a simple integer, it specifies a size in bytes
  if  is an integer followed by 'K', it specifies a size in KiB
  if  is an integer followed by 'M', it specifies a size in MiB

hope this works...

[Sujay Krishna]

Hi everyone,

use a built-in application with the help of intents... (if any)...

[android-beginners] Android specific property

[arvind krishna]

Hi,

I have the following requirement: based on the platform (Linux, Windows etc) I 
need to set some properties which in turn affects software behavior. I was 
looking at querying "os.name" property which is set to "Linux" "Windows*" etc. 
However, when I run the software on the Android Emulator os.name is Linux as 
well. 

My question: Does Android set any property (that tells me that I am on Android) 
by default that I can query and use? 

Thanks in Advance,
Arvind
