Android SecurityException：權限拒絕

我的Android應用有權限問題：這裏是日誌。Android SecurityException：權限拒絕

我知道這是一個權限問題，我可以與人的許可這樣解決：

// Here, thisActivity is the current activity 
if (ContextCompat.checkSelfPermission(thisActivity, 
       Manifest.permission.READ_CONTACTS) 
     != PackageManager.PERMISSION_GRANTED) { 

    // Should we show an explanation? 
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
      Manifest.permission.READ_CONTACTS)) { 

     // Show an expanation to the user *asynchronously* -- don't block 
     // this thread waiting for the user's response! After the user 
     // sees the explanation, try again to request the permission. 

    } else { 

     // No explanation needed, we can request the permission. 

     ActivityCompat.requestPermissions(thisActivity, 
       new String[]{Manifest.permission.READ_CONTACTS}, 
       MY_PERMISSIONS_REQUEST_READ_CONTACTS); 

     // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
     // app-defined int constant. The callback method gets the 
     // result of the request. 
    } 
}

，然後以此來權限設置爲我的供應商：

@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 
    } 
}

問題是我不知道在我的項目的哪一部分我必須把這個權限請求：我使用Auth0自定義UI登錄，Mysqlite作爲內部數據庫se和GoogleCards的ListView。

你能幫我理解如何授予這個權限拒絕嗎？

非常感謝你

我希望你給予權限清單文件readcontact –

那麼我會推薦使用Ask，它是一個權限助手庫。

使用這個，你不必編寫這麼多的代碼，只需兩行就可以完成你的任務。

下面是使用細節

首先編譯依賴於你的build.gradle

dependencies { 
    compile 'com.vistrav:ask:2.4' 
}

，然後在活動開始在OnCreate或任何按下按鈕，你可以問這樣

權限

Ask.on(this) 
    .forPermissions(Manifest.permission.READ_CONTACTS) 
    .go();

這就是它。

你可以找到更多的信息here。我幾乎在所有項目中都使用它，而且它簡單易用。

希望它可以幫助

哇這個問題庫看起來很簡單！ – HendraWD

當然，你必須把它放在任何活動。此功能是否需要運行您的應用程序？詢問應用程序開始。如果你的應用程序可以在沒有它的情況下工作 - 在不可避免的情況下閱讀聯繫人（在一個視圖中）。

Basically you have to check for these permission just before the code where you want to access the contacts. 

    First of all check for the android version,if it is >=23 then 

    if (ContextCompat.checkSelfPermission(thisActivity, 
        Manifest.permission.READ_CONTACTS) 
      != PackageManager.PERMISSION_GRANTED) { 

     // Should we show an explanation? 
     if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
       Manifest.permission.READ_CONTACTS)) { 

      // Show an expanation to the user *asynchronously* -- don't block 
      // this thread waiting for the user's response! After the user 
      // sees the explanation, try again to request the permission. 

     } else { 

      // No explanation needed, we can request the permission. 

      ActivityCompat.requestPermissions(thisActivity, 
        new String[]{Manifest.permission.READ_CONTACTS}, 
        MY_PERMISSIONS_REQUEST_READ_CONTACTS); 

      // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
      // app-defined int constant. The callback method gets the 
      // result of the request. 
     } 
    } 
    else 
    { 
    // do here contact related work say you wwant to fetch the name and number from contact,you can do that task here. 
    } 

You have to override this method: 


@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 
    }

的Android版本低於6.0簡單地定義你的清單在堆棧跟蹤（READ_CONTACTS，WRITE_CONTACTS等）中提到的權限會工作。

對於android 6.0及更高版本，您將不得不要求用戶授予權限。理想情況下，應該在絕對必要時完成，例如當用戶導航到需要該權限的應用程序部分時。這是解釋here。
