Hi, I'm trying to make an app that detects when a user takes a photo.
I set up a broadcast receiver class and registered it in the manifest
file by:
<receiver android:name="photoReceiver" >
<intent-filter>
<action android:name="com.android.camera.NEW_PICTURE"/>
<data android:mimeType="image/*"/>
</intent-filter>
</receiver>
No matter what I try to do the program won't receive the broadcast.
Here is my receiver class:
public class photoReceiver extends BroadcastReceiver {
private static final String TAG = "photoReceiver";
@Override
public void onReceive(Context context, Intent intent) {
CharSequence text = "caught it";
int duration = Toast.LENGTH_LONG;
Log.d(TAG, "Received new photo");
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
}
If I remove the mimeType line in the manifest and in my activity I
send my own broadcast using
Intent intent = new Intent("com.android.camera.NEW_PICTURE");
sendBroadcast(intent);
then I successfully receive the broadcast and can see the log and
toast window. Am I approaching this the right way? Is there any thing
that I need to add? Thanks in advance for the help!
Also, the NEW_PICTURE is defined in the camera source, see a thread
here: stackoverflow.com/questions/3015448/…, when a picture is taken
it calls sendBroadcast(new Intent("com.android.camera.NEW_PICTURE",
mLastContentUri));
