Application wont ask for camera permission

I am developing an Application for Android devices and I wanted to scan QR codes, but I have one problem, it just wont ask for the Camera permission, therefore the surfaceview just stays black.
My Code:
public class ScanQR extends AppCompatActivity {
private SurfaceView surfaceView;
private CameraSource cameraSource;
private TextView textView;
private BarcodeDetector barcodeDetector;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scan_qr);
surfaceView = (SurfaceView) findViewById(R.id.scanQR);
textView = (TextView) findViewById(R.id.tvScanQr);
barcodeDetector = new BarcodeDetector.Builder(this).setBarcodeFormats(Barcode.QR_CODE).build();
cameraSource = new CameraSource.Builder(this, barcodeDetector).setRequestedPreviewSize(640, 480).build();
surfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {
#Override
public void surfaceCreated(SurfaceHolder holder) {
if (ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
return;
} try {
cameraSource.start(holder);
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
cameraSource.stop();
}
});
barcodeDetector.setProcessor(new Detector.Processor<Barcode>() {
#Override
public void release() {
}
#Override
public void receiveDetections(Detector.Detections<Barcode> detections) {
SparseArray<Barcode> qrCodes = detections.getDetectedItems();
if(qrCodes.size() > 0){
textView.post(new Runnable() {
#Override
public void run() {
Vibrator vibrator = (Vibrator) getApplicationContext().getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(1000);
textView.setText(qrCodes.valueAt(0).displayValue);
}
});
}
}
});
}

If anyone could help me with this problem I would be really grateful, I just have no clue of what is going on.
I also have the implementation:
"implementation 'com.google.android.gms:play-services-vision:15.0.2'" and google().
Thanks for any help!

When you're about to open the camera, include the following check:
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(YourCameraActivity.this, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CAMERA_PERMISSION);
return;
}
and handle the result with:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == REQUEST_CAMERA_PERMISSION) {
if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
// close the app
Toast.makeText(CameraActivity.this, "The app requires that permission in order to work properly!", Toast.LENGTH_LONG).show();
finish();
}
}
}
and in your manifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Android Nougat returns null while capturing video

Android version7 returns null URI.

Note given permission in the code but set when launching the application, but still, it is not working, it returns null onActivityResult() if it's Android 7. In Android 6 working fine

put these line in the onCreate() method in your activity or in onCreateView() method in your fragment.
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());

Using QR and NFC technology together in an Android app

I am developing an Android app consisting of two activites so far. The first activity (MainActivity) is started when the app is launched or when a QR code is scanned. The MainActivity starts the second activity (NFCActivity) when the user presses a button. The NFCActivity waits for the user to tap a NFC token, reads out data from the token, and returns the read data to the MainActivity.
This works fine if the app is started manually. If the app is started by scanning a QR code, taping the NFC tag does not invoke the NFCActivity's onNewIntent() method as exepcted, but instead creates a new instance of the NFCActivity on top of the already displayed one.
The enableForegroundDispatch() method is called and FLAG_ACTIVITY_SINGLE_TOP should be set. Relevant source code of a minimal example is provided below. Any help would be highly appreciated!
MainActivity:
public class MainActivity extends Activity {
private EditText dataRead;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
dataRead = (EditText) findViewById(R.id.data);
final Button readKeyButton = (Button) findViewById(R.id.readNFC);
readKeyButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent keyIntent = new Intent(MainActivity.this,
NFCActivity.class);
keyIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivityForResult(keyIntent, 1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == 1) {
String result = intent.getExtras().getString("resultData");
this.dataRead.setText(result);
}
}
}

In case somebody is facing a similar problem: I was finally able to overcome the issue described above by setting the android:launchMode property for the MainActivity to singleInstance.

Google Map APIs Map Creating Error

I created fragment in .xml file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
and I also init. GoogleMap and fragment objects in .java file:
private GoogleMap maps;
private View fragment1;
fragment1 = findViewById(R.id.map);
but When I was trying to create GoogleMap object
maps = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
I'm getting an error on getFragmentManager() eclipse couldn't find this method
How can I overcome this issue?

Make sure that your class extends FragmentActivity and your android project is google api project.

in Xml File
<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
and in Java File
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = fm.getMap();
follow this tutorial
Google Map Using Fragment
in your manifest file
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<application>
...
<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="HERE GOES YOUR API KEY" />
</application>

pls import the class , "import android.support.v4.app.FragmentActivity " Class in your main activity.
it can be imported if u have the google play service downloaded.

Check your manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.
android:versionCode="1"
android:versionName="1.0" >

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Check your layout file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Check your source file:
GoogleMap googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

no need to extend FragmentActivity
try below code:
public class MainActivity extends Activity {
private GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Loading map
initilizeMap();
}
#Override
protected void onResume() {
super.onResume();
initilizeMap();
}
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (googleMap == null) {
Toast.makeText(getApplicationContext(), "Sorry! unable to create maps",
Toast.LENGTH_SHORT).show();
}
}
}
}

Android GoogleMaps API v2 auth error, i do not get the error when running on an AVD but on my nexus 7 i get an auth error

I am developing an Android application which uses Google maps for android v2. The problem i having is that when i run it using the AVD in Eclipse i recieve no authentication error in the log cat output.
I am now testing my application on an Android tablet (nexus 7 2013) and i recieve this error when executing the application:
12-12 01:09:13.968: E/Google Maps Android API(14759): Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
12-12 01:09:13.968: E/Google Maps Android API(14759): Ensure that the following correspond to what is in the API Console: Package Name: dcs.aber.ac.uk.cs211.group02, API Key: AIzaSyDcnzt6cdjEbCXSCRSTezmUHbaPW679if8, Certificate Fingerprint: 52FDB9ABBBAA062226834E35BF6A39FA2A3E27A7
I have tried to regen the API key, the one in the logcat matches the one provided in the google API console.
I have tried a clean project/clean install on the device several times, still no luck. The reast of the application works fine, only the map does not.
Here is my manifest.xml al the permissions seem ok.
