android - Android "SuperNotCalledException:Activity did not call through to super.OnCreate()"错误

Question

uncaught handler:thread main exiting due to uncaught exception android.app.SuperNotCalledException:Activity did not call through to super.OnCreate()

我的代码是:

  public void onCreate(Bundle savedInstanceState) {
        boolean isEnabled = Settings.System.getInt(this.getApplicationContext().getContentResolver(),Settings.System.AIRPLANE_MODE_ON, 0) == 1;


                Settings.System.putInt(this.getApplicationContext().getContentResolver(),Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);

                // Post an intent to reload
                Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
                //intent.putExtra("state",! isEnabled);//Call ON
                try {
                    Thread.sleep(15000);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                intent.putExtra("state", isEnabled);
                                                                                           this.getApplicationContext().sendBroadcast(intent);


}

添加super.onCreate(savedInstanceState);

 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
        boolean isEnabled = Settings.System.getInt(this.getApplicationContext().getContentResolver(),Settings.System.AIRPLANE_MODE_ON, 0) == 1;
