I am getting permission issues while trying for Bluetooth device discovery.
Issue:- "requires android.permission.ACCESS_COARSE_LOCATION due to sender com.android.bluetooth" already added the following permissions to manifest
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
The correct procedure for BT device discovery on Marshmallow is as follows:
1) Have ACCESS_COARSE_LOCATION permission requirement in manifest along with usual bluetooth permissions:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
2)Ensure you have run-time permission for ACCESS_COARSE_LOCATION
protected void checkLocationPermission() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
REQUEST_COARSE_LOCATION);
}
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_COARSE_LOCATION: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
proceedDiscovery(); // --->
} else {
//TODO re-request
}
break;
}
}
}
3) Register a broadcast receiver for ACTION_FOUND and call
BluetoothAdapter.startDiscovery()
protected void proceedDiscovery() {
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
filter.addAction(BluetoothDevice.ACTION_NAME_CHANGED);
registerReceiver(mReceiver, filter);
mBluetoothAdapter.startDiscovery();
}
