android 6.0 Runtime-Erlaubnis nicht funktionieren

Question

ich zur Laufzeit der Erlaubnis zum ersten Mal auf Android 6.0 arbeite und hier ist mein Code:

String[] permissionsRequired = new String[]{Manifest.permission.CAMERA, 
     Manifest.permission.WRITE_EXTERNAL_STORAGE, 
     Manifest.permission.RECORD_AUDIO, Manifest.permission.READ_EXTERNAL_STORAGE}; 

private void checkPermission() { 
    if (ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[0]) != PackageManager.PERMISSION_GRANTED || 
      ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[1]) != PackageManager.PERMISSION_GRANTED || 
      ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[2]) != PackageManager.PERMISSION_GRANTED || 
      ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[3]) != PackageManager.PERMISSION_GRANTED) { 
     if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[0]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[1]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[2]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[3])) { 

      AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); 
      builder.setTitle("Need Multiple Permissions"); 
      builder.setMessage("This app needs Camera and Location permissions."); 
      builder.setPositiveButton("Grant", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
        ActivityCompat.requestPermissions(getActivity(), permissionsRequired, PERMISSION_CALLBACK_CONSTANT); 
       } 
      }); 
      builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
       } 
      }); 
      builder.show(); 
     } else if (permissionStatus.getBoolean(permissionsRequired[0], false)) { 
      //Previously Permission Request was cancelled with 'Dont Ask Again', 
      // Redirect to Settings after showing Information about why you need the permission 
      AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); 
      builder.setTitle("Need Multiple Permissions"); 
      builder.setMessage("This app needs Camera and Location permissions."); 
      builder.setPositiveButton("Grant", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
        sentToSettings = true; 
        Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); 
        Uri uri = Uri.fromParts("package", getContext().getPackageName(), null); 
        intent.setData(uri); 
        startActivityForResult(intent, REQUEST_PERMISSION_SETTING); 
        Toast.makeText(getContext(), "Go to Permissions to Grant Camera and Location", Toast.LENGTH_LONG).show(); 
       } 
      }); 
      builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
       } 
      }); 
      builder.show(); 
     } else { 
      //just request the permission 
      ActivityCompat.requestPermissions(getActivity(), permissionsRequired, PERMISSION_CALLBACK_CONSTANT); 
     } 


     permissionStatus = getContext().getSharedPreferences("permission status", 0); 
     SharedPreferences.Editor editor = permissionStatus.edit(); 
     editor.putBoolean(Manifest.permission.WRITE_EXTERNAL_STORAGE, true); 
     editor.apply(); 


    } else { 
     //You already have the permission, just go ahead. 
     proceedAfterPermission(); 
    } 
} 

private void proceedAfterPermission() { 
    Toast.makeText(getContext(), "We got All Permissions", Toast.LENGTH_LONG).show(); 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    if (sentToSettings) { 
     if (ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[0]) == PackageManager.PERMISSION_GRANTED) { 
      //Got Permission 
      proceedAfterPermission(); 
     } 
    } 
} 
@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
    if (requestCode == PERMISSION_CALLBACK_CONSTANT) { 
     //check if all permissions are granted 
     boolean allgranted = false; 
     for (int i = 0; i < grantResults.length; i++) { 
      if (grantResults[i] == PackageManager.PERMISSION_GRANTED) { 
       allgranted = true; 
      } else { 
       allgranted = false; 
       break; 
      } 
     } 

     if (allgranted) { 
      proceedAfterPermission(); 
     } else if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[0]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[1]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[2]) 
       || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[3])) { 
      AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); 
      builder.setTitle("Need Multiple Permissions"); 
      builder.setMessage("This app needs Camera and Location permissions."); 
      builder.setPositiveButton("Grant", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
        ActivityCompat.requestPermissions(getActivity(), permissionsRequired, PERMISSION_CALLBACK_CONSTANT); 
       } 
      }); 
      builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
       } 
      }); 
      builder.show(); 
     } else { 
      Toast.makeText(getContext(), "Unable to get Permission", Toast.LENGTH_LONG).show(); 
     } 
    } 
} 

Ich habe definiert auch Kamera, Audio aufnehmen, las & externe Speicher schreiben Berechtigungen in Manifest.

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

Was ist das Problem dabei?

Menifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.saubhagyam.videouploadingdemo"> 

<uses-sdk android:minSdkVersion="10" /> 

<uses-feature android:name="android.hardware.camera2" /> 

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

<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:roundIcon="@mipmap/ic_launcher_round" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme"> 
    <activity android:name=".MainActivity"> 

    </activity> 
    <activity android:name=".Bio"></activity> 
    <activity android:name=".MyCameraRecorder"></activity> 
    <activity android:name=".Container"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

Answer 1

können Sie unten verwenden wie

ActivityCompat.requestPermissions(getActivity(), permissionsRequired, PERMISSION_CALLBACK_CONSTANT); 

ActivityCompat.checkSelfPermission(getContext(), permissionsRequired[0]) != PackageManager.PERMISSION_GRANTED 

ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permissionsRequired[0]) 

Änderung

requestPermissions(permissionsRequired, PERMISSION_CALLBACK_CONSTANT); 

context.checkSelfPermission(permissionsRequired[0]) != PackageManager.PERMISSION_GRANTED 

shouldShowRequestPermissionRationale(permissionsRequired[0]) 

Ihrem Kontext wie Context context = getActivity(); für Fragment und f oder Aktivität Context context = MainActivity.this;
