Abdallah Mohammed :

I can't believe why this code not working. I tried several times but to no avail, how can I solve this problem, how are you doing it?

Flying Dutchman :

I believe you haven't ask for the runtime permission

private int REQUEST_CODE_PERMISSIONS = 101;
private final String[] REQUIRED_PERMISSIONS = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE,
        Manifest.permission.RECORD_AUDIO,
        Manifest.permission.CAMERA
};

 if (allPermissionsGranted()) {
    startCamera(); //start camera if permission has been granted by user
} else {
    ActivityCompat.requestPermissions(this, REQUIRED_PERMISSIONS, REQUEST_CODE_PERMISSIONS);
}

Calling Permssion Context

 private boolean allPermissionsGranted(){

    for(String permission : REQUIRED_PERMISSIONS){
        if(ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED){
            return false;
        }
    }
    return true;
}

if Permission not granted

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    if(requestCode == REQUEST_CODE_PERMISSIONS){
        if(allPermissionsGranted()){
            startCamera();
        } else{
            Toast.makeText(this, "Permissions not granted by the user.", Toast.LENGTH_SHORT).show();
            finish();
        }
    }
}
