Сбой разрешения времени выполнения камеры RTMP

0 голосов
/ 18 сентября 2018

Я использую библиотеку https://github.com/Karumi/Dexter для предоставления разрешения моей камере.При тестировании с нормальной камерой все работает хорошо, но когда я использую библиотеку https://github.com/pedroSG94/rtmp-rtsp-stream-client-java для потоковой передачи RTMP, я получаю ошибку и не могу получить доступ к камере.Кто-нибудь знает, как решить эту проблему?

В Основном действии я определяю разрешение Декстера и кнопку для доступа к активности камеры

MainActivity 

public class MainActivity extends AppCompatActivity {

    private Button btnCamera;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnCamera = findViewById(R.id.btn_camera);


        btnCamera.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                requestCameraPermission();
