Android在運行時詢問權限在運行時拋出異常

我試圖在運行時請求權限在android棉花糖。但我的應用程序在這裏崩潰是我的代碼。Android在運行時詢問權限在運行時拋出異常

private void showWebpage() { 
    if (checkSelfPermission(Manifest.permission.INTERNET) == PackageManager.PERMISSION_GRANTED) { 
     Toast.makeText(this, "Permission Granted", Toast.LENGTH_LONG).show(); 
    } else { 

     requestPermissions(new String[]{Manifest.permission.INTERNET},REQUEST_INTERNET); 
    } 
} 

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
}

當我調用showWebpage（）方法時，應用程序崩潰。控制權轉到else部分並調用requestPermissions方法，但應用程序崩潰。這裏是我的logcat錯誤

請幫助我，它真的很重要:(

這是真的日誌從您的應用程序 –

-1

的INTERNET權限已保護級別normal，你並不需要在運行時要求它，你應該只申報您的應用程序是在清單中使用它：？

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

但我得到同樣的錯誤，每許可，我試着用相機相同的代碼得到同樣的錯誤 – Rahul
