So I am creating an app that requests permission to a users google account. I used mine to test and so I gave it permission and then removed it to see if it would ask for it again. It was still using the token it got so I deleted the app from my phone and reinstalled it. I didn't change any code and now all of a sudden it only shows the account page (to select which account) and then once I press ok, nothing shows to give it permission. In my run console I get the following:
$ adb push C:\Users\James Singleton\AndroidStudioProjects\ChffrAPI\app\build\outputs\apk\app-debug.apk /data/local/tmp/com.example.jamessingleton.chffrapi
$ adb shell pm install -r "/data/local/tmp/com.example.jamessingleton.chffrapi"
pkg: /data/local/tmp/com.example.jamessingleton.chffrapi
Success
$ adb shell am start -n "com.example.jamessingleton.chffrapi/com.example.jamessingleton.chffrapi.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER

I am using foreground service for detecting beacons since Android Oreo kills all background services, we decided to go on with foreground service to detect beacons when the app is in foreground/killed/in background.
This works fine on android 7.0 and below but on android 8 it throws an error "No task registered for key "didEnterRegion"
This is my code
Helper.java
public static void sendNewBeacons(Context context, Collection<Beacon> beacons) {
if (beacons != null && beacons.size() > 0) {
for (Beacon beacon : beacons) {
Intent service = new Intent(context, MyTaskService.class);
service.putExtra("eventName", "didEnterRegion");
service.putExtra("beacon", (Parcelable) beacon);
context.startService(service);
HeadlessJsTaskService.acquireWakeLockNow(context);
}
}
}
public static void sendRemovedBeacons(Context context, Collection<Beacon> beacons) {
if (beacons != null && beacons.size() > 0) {
for (Beacon beacon : beacons) {
Intent service = new Intent(context, MyTaskService.class);
service.putExtra("eventName", "didExitRegion");
service.putExtra("beacon", (Parcelable) beacon);
context.startService(service);
HeadlessJsTaskService.acquireWakeLockNow(context);
}
}
}
This is TaskService code
public class MyTaskService extends HeadlessJsTaskService {
private final String TAG = "TaskService";
#Override
protected #Nullable
HeadlessJsTaskConfig getTaskConfig(Intent intent) {
Bundle extras = intent.getExtras();
if (extras == null) {
return null;
}
String event = extras.getString("eventName");
if (TextUtils.isEmpty(event)) {
return null;
}
WritableMap map = new WritableNativeMap();
if (extras.containsKey("beacon")) {
map = BeaconHelper.getObject((Beacon)
extras.getParcelable("beacon"));
}
Log.d(TAG, event);
return new HeadlessJsTaskConfig(event, map,5000, true);
}
#Override
public void onHeadlessJsTaskFinish(int taskId) {
super.onHeadlessJsTaskFinish(taskId);
}
This is my App.js
AppRegistry.registerHeadlessTask('didEnterRegion', () =>
require('./BeaconEntering.js'));
AppRegistry.registerHeadlessTask('didExitRegion', () =>
require('./BeaconExiting.js'));
const myModuleEvt = new
NativeEventEmitter(NativeModules.BeaconManager);
const rangeBeacon = myModuleEvt.addListener('didRangeBeacons',
Util.didRangeBeacons);
const exitRegion = myModuleEvt.addListener('didExitRegion',
Util.didExitRegion);
const entryRegion =
myModuleEvt.addListener('didEnterRegion',Util.didEnterRegion);
This is a log before crash

Found the fix,
We need to define the function first
const didEnterRegion = async (data) => {
console.log(data);
};
and then register the headlessTask
AppRegistry.registerHeadlessTask('didEnterRegion', () => didEnterRegion);

I have been working on an app which needs to find some discoverable Bluetooth devices. I have followed guides and looked at answers on here and followed. However I cannot seem to get the phone to start scanning.
Here is the full activity code:
public class MainActivity extends AppCompatActivity {
private TextView scanningText;
private ListView scanningListView;
private Button scanningButton;
boolean scanComplete;
private final static int REQUEST_ENABLE_BT = 1;
private ArrayList<String> mDeviceList;
private BluetoothAdapter mBluetoothAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDeviceList = new ArrayList<>();
scanningButton = (Button) findViewById(R.id.scanningButton);
scanningText = (TextView) findViewById(R.id.scanningText);
scanningListView = (ListView) findViewById(R.id.scanningList);
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
scanningText.setText("Your device does not support Bluetooth, Sorry!");
}
else if (!mBluetoothAdapter.isEnabled()) {
scanningText.setText("You need to enable bluetooth to use this app..");
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
// Register for broadcasts when a device is discovered.
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver, filter);
scanningButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
scanningText.setText("Scanning...");
mBluetoothAdapter.startDiscovery();
}
});
}
#Override
protected void onDestroy() {
unregisterReceiver(mReceiver);
super.onDestroy();
}
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
mDeviceList.add(device.getName() + "\n" + device.getAddress());
Log.i("BT", device.getName() + "\n" + device.getAddress());
scanningListView.setAdapter(new ArrayAdapter<>(context,
android.R.layout.simple_list_item_1, mDeviceList));
}
else {
Log.i("BT", "none"+ "");
}
}
};
}
When I check the android log console, there are no logs.
Thanks
Update:
I have moved startDiscovery to the onclick listener.
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
// There are paired devices. Get the name and address of each paired device.
for (BluetoothDevice device : pairedDevices) {
String deviceName = device.getName();
String deviceHardwareAddress = device.getAddress(); // MAC address
}
Log.i("found", pairedDevices + "");
}
The following check takes place when i press the scan button. I am told the device is not discovering by the toast.
scanningButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
scanningText.setText("Scanning...");
mBluetoothAdapter.startDiscovery();
if (mBluetoothAdapter.isDiscovering()) {
mBluetoothAdapter.isDiscovering();
Toast toast = Toast.makeText(getApplicationContext(), "discovering", Toast.LENGTH_LONG);
toast.show();
}
else {
Toast toast = Toast.makeText(getApplicationContext(), "not discovering", Toast.LENGTH_LONG);
toast.show();
}
}
});

Try adding those permissions in the manifest :
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Also, it's always recommended to ask the user for permissions, so here you go :
if (Build.VERSION.SDK_INT >= 23 && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
}
if(Build.VERSION.SDK_INT >= 23 && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
}
You should start by adding logs at every steps.
Log.i("TAG", "Message")
Does your manifest file contains the appropriate permissions?
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
Next, it seems like you do not check if the bluetooth is enabled on the device. You should use an intent to do so.
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBT = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBT, REQUEST_BLUETOOTH);
}
I am trying to create a class that sets and starts audio recording but as soon as I click the button the app crashes. Iv isolated the problem to where I set the parameters for the MediRecorder.
private void startRec() throws IOException {
if (mrecorder!=null)
mrecorder.release();
mrecorder= new MediaRecorder();
-> mrecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
/*
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mrecorder.setOutputFile(MFILE);
mrecorder.prepare();
mrecorder.start();
*/
}
It crashes when the line with the arrow above the start of the notes is executed. I added the following permission to the manifest as well:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Any help much appreciated.

I have been trying to learn how to use the GCM by going over their step by step guild. I get to the point of registering but it never actually does the registration part of the project. I have the configuration file in the project and I am using this website to test for push notification http://www.androidbegin.com/tutorial/gcm.html
So this is what it is giving me in the logcat:

As it shows it get down to the start(intent0 part of the onCreate method. But it never reaches to the Register class at all. I am a bit stumped on what I am doing wrong here. Any help will be appreciated.
here is the main activity code that starts the app
