在android棉花糖没有被授予的所有权限

问题描述：

我正在给运行时权限给我的android设备。在我的情况下，只要用户点击通话按钮，它应该要求3个权限CALL_PHONE，CAMERA和RECORD_AUDIO。它要求我可以在日志中看到的权限，但只有一个权限被授予。再次，如果我杀了我的应用程序，并点击Call按钮，现在正在询问第二个权限，并且nxt时间是lats之一。所有3个都没有被同时询问。正如我在日志中看到的那样，它只会在第一时间询问并授予所有许可，但一次只能询问一个。在android棉花糖没有被授予的所有权限

你为什么不试着问所有权限在一个ActivityCompat.requestPermissions（这一点，新的String [] {Manifest.permission.GET_ACCOUNTS，Manifest.permission.READ_SMS，Manifest.permission.ACCESS_FINE_LOCATION}， REQUEST_GET_ACCOUNTS）; – Tasneem

'工作时给予我的android设备运行时权限。不，不要你的设备。但对你的应用程序。代码，以便用户可以将权限授予您的应用程序。 – greenapps

让重写此方法，它将处理程序的结果。

@Override 
    public void onRequestPermissionsResult(int requestCode, 
      String permissions[], int[] grantResults) { 
     switch (requestCode) { 
      case MY_PERMISSIONS_REQUEST_READ_CONTACTS: { 
       // If request is cancelled, the result arrays are empty. 
       if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        // permission was granted, yay! Do the 
        // contacts-related task you need to do. 

       } else { 

        // permission denied, boo! Disable the 
        // functionality that depends on this permission. 
       } 
       return; 
      } 

      // other 'case' lines to check for other 
      // permissions this app might request 
     } 
    }
