I referred to all the other StackOverflow posts about this problem and I can't get it to work properly.
My goal is to write an app with no main activity, just a service. You should be able to bind to it from a seperate app and interact with it using AIDL.
I previously had both the service and the activity calling it in the same app and it worked flawlessly. But I need to get it working between two seperate apps.
The onBind() of the service looks like this:
@Nullable
@Override
public IBinder onBind(Intent intent) {
// This binds the bluetooth service itself to the logger service, do this when the logger service itself is bound
Intent serviceIntent = new Intent(this, BluetoothService.class);
intent.setPackage(this.getPackageName());
Log.d(getClass().getName(), "started");
if(bluetoothService == null) {
if (this.bindService(serviceIntent, bluetoothServiceConnection, BIND_AUTO_CREATE)) {
Log.d(getClass().getName(), "returned the service");
return mBinder;
} else {
Log.d(getClass().getName(), "returned null");
return null;
}
} else {
Log.d(getClass().getName(), "returned the service");
return mBinder;
}
}
The service itself binds to another service, but all of the bluetooth stuff works already.
The Manifest of the app with the service looks like this:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<application
android:label="@string/app_name">
<service
android:label="LoggerService"
android:name="io.modum.ble.LoggerService"
android:exported="true">
<intent-filter>
<action android:name="io.modum.ble.LoggerService" />
</intent-filter>
</service>
<service android:name="io.modum.ble.service.BluetoothService" />
</application>
In my activity, I bind to it like this:
Intent intent = new Intent();
ComponentName componentName = new ComponentName("io.modum.modum_ble_service", "io.modum.ble.LoggerService");
intent.setComponent(componentName);
boolean success = getApplicationContext().bindService(intent, new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
Log.d(getClass().getName(), "Service connected");
}
@Override
public void onServiceDisconnected(ComponentName name) {
}
}, BIND_AUTO_CREATE);
Log.d(getClass().getName(), String.valueOf(success));
The AIDL files have the exact same package name in both applications.
No exception is called, everything works except onServiceConnected is not called.
bindService() returns true, the service receives the intent and is correctly started, "returned the service" is logged, but onServiceConnected() is never called.
