Android在运行时询问权限在运行时抛出异常

我试图在运行时请求权限在android棉花糖。但我的应用程序在这里崩溃是我的代码。Android在运行时询问权限在运行时抛出异常

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); 
}

当我调用showWebpage（）方法时，应用程序崩溃。控制权转到else部分并调用requestPermissions方法，但应用程序崩溃。这里是我的logcat错误

这是真的日志从您的应用程序 –

-1

的INTERNET权限已保护级别normal，你并不需要在运行时要求它，你应该只申报您的应用程序是在清单中使用它：？

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