Examples with Handler android.os.Handler used on opensource projects

Example 56 with Handler

use of android.os.Handler in project platform_frameworks_base by android.

the class DropBoxManagerService method onStart.

@Override
public void onStart() {
    // Set up intent receivers
    IntentFilter filter = new IntentFilter();
    filter.addAction(Intent.ACTION_DEVICE_STORAGE_LOW);
    getContext().registerReceiver(mReceiver, filter);
    mContentResolver.registerContentObserver(Settings.Global.CONTENT_URI, true, new ContentObserver(new Handler()) {

        @Override
        public void onChange(boolean selfChange) {
            mReceiver.onReceive(getContext(), (Intent) null);
        }
    });
    publishBinderService(Context.DROPBOX_SERVICE, mStub);
// The real work gets done lazily in init() -- that way service creation always
// succeeds, and things like disk problems cause individual method failures.
}
