Android.util.AndroidRuntimeException: вы не можете комбинировать удаление салфетки и панель действий

Я новичок в программировании на Android и начал образец приветственной мировой программы, но застрял с ошибкой ниже:

MainActivity.Java

package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
}

activity_main.xml

        android:text="@string/hello" />

</RelativeLayout>

Пожалуйста, помогите мне узнать, где я ошибаюсь, в настоящее время я на Android 4.3, API 18,

Я пробовал Android 4.0.3 API 15, Android 4.4W API 20; Я также пробовал редактировать sdk, как показано ниже, но не повезло.

<uses-sdk
   android:minSdkVersion="15"
   android:targetSdkVersion="19" />
