[android-developers] programmatic bluetooth pairing
I have a known good MAC address for a bluetooth device and I wish to
initiate pairing programmatically. This would allow the user to pair
without going to the bluetooth settings screen and manually pairing.
I want to avoid having to rely on reflection as in the following
example, but I want the same result:
Method m = device.getClass().getMethod("createRfcommSocket", new
Class[] {int.class});
BluetoothSocket socket = (BluetoothSocket) m.invoke(device, 1);

[android-developers] Loading soundpool and music in activity A and calling in Activity B
Hi!
Right now I am loading my tiny music clips in the same class that I am using
it in like this:
public static final int A1 = 1;
public static final int A3 = 3;
private SoundPool soundPool;
private HashMap soundPoolMap;
soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 100);
soundPoolMap = new HashMap();
soundPoolMap.put(A1,soundPool.load(GameScreen_bugfix.this, R.raw.a, 1));
soundPoolMap.put(A3,soundPool.load(GameScreen_bugfix.this, R.raw.b, 1));
//etc
AudioManager mgr = (AudioManager)
GameScreen_bugfix.this.getSystemService(Context.AUDIO_SERVICE);
float streamVolumeCurrent = mgr.getStreamVolume(AudioManager.STREAM_MUSIC);
float streamVolumeMax = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
float volume = streamVolumeCurrent / streamVolumeMax;
try {
soundPool.play(soundPoolMap.get(sound), volume, volume, 1, 0,
1f);
} catch (Exception e) {
e.printStackTrace();
}
Can someone please tell me how I can load all the soundclips in Activity A,
and then call them in Activity B?
Thanks!
Ryan

Re: [android-developers] AsyncTask doInBackground bug
I am using 2.1 in the emulator and 2.2.2 on my LG optimum and 2.3 on my Wildfire S... the same thing happens in all 3 :( Works fine till 4 or 5 times, then the threads dont start. Thinking of rewriting it to use normal threads instead and a call to runOnUiThread. On Fri, Sep 30, 2011 at 5:15 PM, Mark Murphy wrote: > Well, the code in that SO question is fairly weak.
