You can try AudioServiceFragmentActivity instead of AudioServiceActivity. More information about the different ways to define an audio service activity can be found in the audio_service documentation.

Android AIDL - Unable to start service Intent

The error I am receiving is
2022-01-28 11:10:42.186 1651-3045/? W/ActivityManager: Unable to start service Intent { act=nveeaidle pkg=com.rchan.nveeapplication } U=0: not found
I have ensured the following code in both my applications (client and server). In my server manifest:

activity?.applicationContext?.bindService(

}
I am not sure what is causing this warning, and I have tried out different solutions after searching on stackoverflow and google.
How do I test is:
Launch my server application
Launch my client application
I see the warning
Thank you for taking the time to read my question.

After recent changes, You can use <queries> <package android:name ="your package name" /> </queries>
https://developer.android.com/training/package-visibility/declaring

I did more searching and finally found the answer... All credits go to the SO answer here:
https://stackoverflow.com/a/55712326/3718584
TLDR:
Had to change the intent from implicit to explicit due to API 21
intent.setClassName("com.rchan.nveeapplication","com.rchan.nvee_sdk.detectedactivity.DetectedActivityService")

Parse.com push notifications don't get to devices on background

Today I've implemented Parse.com Push service in my app.
I've noticed that the push notifications are being sent only when the app is open. I've also noticed that whenever I'm turning on my device there is a message says "Unfortunately, tof has stopped". The Logcat says Unable to start receiver.
The full Logcat:

I've tried to search on the Web but I didn't find any solution. I guess that it's something about the receiver background operation.
I need an answer as quickly as possible, so if you know a bit about Parse SDK and it's push topic so please, help me 'cause I need to solve this today.
This is my code.
MainActivity.java:
ParsePush parsePush = new ParsePush();
ParseQuery pQuery = ParseInstallation.getQuery(); // <-- Installation query
pQuery.whereEqualTo("username", User_Name);
parsePush.sendMessageInBackground(message, pQuery);

i.putExtras(intent.getExtras());
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

}
}
I need major help right now!! Please help me!

Follow the steps below. This code works fine and run the receiver on background. The original answer link: https://www.parse.com/apps/quickstart#parse_push/android/native/existing
MainActivity.java file
public void onCreate() {
Parse.initialize(this, "APPLICATION ID", "CLIENT KEY");
ParseInstallation.getCurrentInstallation().saveInBackground();

Have a look at this.
public class MainApplication extends Application {
private static MainApplication instance = new MainApplication();
public MainApplication() {
instance = this;
}
public static Context getContext() {
return instance;
}
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(this, " ", " ");
PushService.setDefaultPushCallback(this, FabulaClient.class);
PushService.subscribe(this, "Barca", FabulaClient.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
}
}
taken from https://www.parse.com/questions/cannot-send-push-to-android-after-app-is-closed-until-screen-unlock

I've understood why I don't get the push notifications on background.
I've initialized parse sdk twice - on the OpenActivity.java and on ParseApplication.java. I've removed it from the OpenActivity.java and added this code line:
android:name=".ParseApplication"
To the application attribute on the AndroidManifest.xml and now I can get push notifications on background.

Unexpectedly Closed Application After Integration Parse.com

There was no problem while running my little android application. I integrated my application new feature. I am using real time push notification with using ready script by www.parse.com . There is no problem while running but when i closed screen and reopen .There is an error. Your application closed unexpectedly. I dont know why and there is no log.
I am using this code in my main activity before oncreate
Parse.initialize(this, "XXX", "YYY");
PushService.setDefaultPushCallback(this, MainActivity.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
ParseAnalytics.trackAppOpened(getIntent());

As you can see here Android Parse.com Simple ListView Tutorial you will need to call Parse.initialize from Application's onCreate instead of from Activity or Service. do it as:
public class ParseApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
// Add your initialization code here
Parse.initialize(this, YOUR_APPLICATION_ID, YOUR_CLIENT_KEY);
}
}
Also add ParseApplication in AndroidManifest.xml as application tag name:
<application
android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:name="ParseApplication"
....

Android Permission Denial: broadcasting Intent

I really do not know what is wrong, but my if widget is update by system by "APPWIDGET_UPDATE" it throws following exception. I tried several things, exporting receiver (true/false), I tried it on emulators and real phones, but it is same. I added several intent-filters, but it did not work.
11-06 20:10:10.279: W/ActivityManager(61): Permission denied: checkComponentPermission() reqUid=1000

My AppWidgetProvider is only declared, because I tried to eliminate possibilities, but the exception is throw before ExchangeRateWidgetProvider.onReceive() is called.
public class ExchangeRateWidgetProvider extends AppWidgetProvider {
public static final String tag = "ExchangeRateWidgetProvider";
#Override

int[] appWidgetIds) {
}

I appreciate if you can take a look ...

Your problem lies somewhere in your Java code, where you are attempting to send the android.appwidget.action.APPWIDGET_UPDATE broadcast. That is to be broadcast by the OS, not by apps, and that is what the Permission Denial is about.
