Did you check to see if torch mode is SUPPORTED by its camera device? See getSupportedFlashModes() in Camera.Parameters (http://developer.android.com/reference/android/hardware/Camera.Parameters.html) for more information. You should ALWAYS check to see if a camera parameter you're trying to set is supported for that device BEFORE you try and set it, or you might cause a force close with the camera open, which in most Androids will[1] lock the camera until the user reboots their Android, which, in turn, can lead to a whole lot of p*ssed off users, 1-star ratings, etc. Later, --jim [1] While my Acer Iconia A500 tablet was still running Honeycomb, if I had an uncaught exception in my camera app (which is now on-hold until the election in November, after which, it may be pointless to release it at all), a force close would NOT lock the camera. Once it upgraded to ICS, that changed, and it DOES get locked up now. So I know it doesn't always happen, but you can bet that it will on most Androids. -- THE SCORE: ME: 2 CANCER: 0 73 DE N5IAL (/4)MiSTie #49997 < Running Mac OS X Lion > spooky1...@gmail.comICBM/Hurr.: 30.44406N 86.59909W No, I'm not going to explain it.

[android-developers] FLASH_MODE_TORCH doesn´t work in Samsung Galaxy Ace
Hello!
I´m writing my first time here.
Here my question:
I´m doing a flash light aplication, and my aplication works in all devices
with flash, but it doesn´t work in some Samsung devices, how Samsung Galaxy
Ace.
I searched in Internet but i don´t find anything... and maybe help me here.
*My source code is:*
public class MainActivity extends Activity {
private Camera cam;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (cam != null) {
Parameters paramCamera = cam.getParameters();
List modesFlash = paramCamera.getSupportedFlashModes();
if (modesFlash != null &&
modesFlash.contains(Camera.Parameters.FLASH_MODE_TORCH)) {
paramCamera.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH);
try {
cam.setParameters(paramCamera);
cam.startPreview();
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
"Error1", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(),
"Error2", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), "Error3", Toast.LENGTH_LONG).show();
}
}
}
Thank you so much
