Android: Pop-up Dialog with AlarmManager

Basic example. The dialog is actually an activity with theme set to "@android:style/Theme.Dialog". Pressing the snooze button will trigger the dialog again after an amount of time.

AndroidManifest.xml

<activity
    android:name="com.example.test.MainActivity$TriggeredActivity"
    android:theme="@android:style/Theme.Dialog"
    android:taskAffinity="" >
</activity>

MainActivity.java

public static final void setAlarm(int seconds, AlarmManager alarmManager,
		Context context) {
	// create the pending intent
	Intent intent = new Intent(context, TriggeredActivity.class);
	// intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
	PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
			intent, PendingIntent.FLAG_ONE_SHOT);
	// get the alarm manager, and scedule an alarm that triggers my
	// activity
	alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
			+ seconds * 1000, pendingIntent);
	Toast.makeText(context, "Timer set to " + seconds + " seconds.",
			Toast.LENGTH_SHORT).show();
}

public static class TriggeredActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.dialog);
		Button dismiss = (Button) findViewById(R.id.dismiss);
		Button snooze = (Button) findViewById(R.id.snooze);
		final Context context = this;
		dismiss.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				finish();
			}
		});
		snooze.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				setAlarm(4, ((AlarmManager) getSystemService(ALARM_SERVICE)), context);
				finish();
			}
		});
	}
}
