대신 MainActivity를 확장하려면 AppCompatActivity을 사용해야합니다. 또한 스택 트레이스를 포함 시키십시오.

public class MainActivity extends AppCompatActivity { 

//...... 
} 

아, 죄송합니다. stacktrace를 사용하면 명확하게 주요 문제를 볼 수 있습니다. android.permission.CAMERA. 요청을하려면 권한 확인을 만들어야합니다. 권한 확인을 만들려면 This Example을 확인하십시오.

예 :

1) 활동에 포함합니다.

<uses-permission android:name="android.permission.CAMERA" /> 

2) 사용자로부터 권한을 요청 확인 :

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 

      ActivityCompat.requestPermissions(this, new String[] { android.Manifest.permission.ACCESS_COARSE_LOCATION }, 
               LocationService.MY_PERMISSION_ACCESS_COURSE_LOCATION); 
} 

3) 런타임

if (Build.VERSION.SDK_INT >= 23 && 
      ContextCompat.checkSelfPermission(context, android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) { 
      return; 
}

안녕 lunatique의 알데바란에서 확인

First of all you need to add the following permission in manifest.xml file.

<uses-permission android:name="android.permission.CAMERA" /> 

Check whether the android device is Marshmallow or not. If its android M or greater version then use the following code to get camera permission dynamically.

Before android M dont want to get dynamic permission.

check if the user grant the permission. If user not granted permission then request the camera permission access.

private static final int MY_CAMERA_REQUEST_CODE = 100; 
if (checkSelfPermission(Manifest.permission.CAMERA) 
        != PackageManager.PERMISSION_GRANTED) { 
      requestPermissions(new String[]{Manifest.permission.CAMERA}, 
         MY_CAMERA_REQUEST_CODE); 
      } 

After requesting the permission alert will display to ask permission contains allow and deny options. After clicking action we can get result of the request with the following method.

@Override 

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

     super.onRequestPermissionsResult(requestCode, permissions, grantResults); 

    if (requestCode == MY_CAMERA_REQUEST_CODE) { 

      if (grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

       Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show(); 

      } else { 

       Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show(); 

      } 

     }
