Question

I want to know how to keep the app from reloading when the orientation is changed?

I have a small test app that will play an audio sound until the stop button is pressed. If I change my Android or the simulator from horizontal to portrait then the stop button does not work. A second occurrence of the app is loaded. I want the first occurrence to keep running regardless if the orientation has been changed.

Main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="fill_parent" android:orientation="horizontal">


<LinearLayout

android:layout_width="wrap_content"

android:layout_height="match_parent"

android:layout_weight="0.64" android:orientation="horizontal">


<Button

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Play" />


<Button

android:id="@+id/button2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Stop" />


</LinearLayout>


</LinearLayout>

Test.java

import android.app.Activity;

import android.media.AudioManager;

import android.media.MediaPlayer;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;


public class TestAppActivity extends Activity {

private Button btnDisplay;

private MediaPlayer mediaPlayer;


@Override

public void onCreate(Bundle savedInstanceState) 

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

setVolumeControlStream(AudioManager.STREAM_MUSIC);

mediaPlayer = MediaPlayer.create(this, R.raw.nut);

mediaPlayer.setLooping(true);


((Button)findViewById(R.id.button1)).setOnClickListener( new View.OnClickListener() {


public void onClick(View v) {

mediaPlayer = MediaPlayer.create(LoopBugActivity.this, R.raw.nut);

mediaPlayer.setLooping(true);

mediaPlayer.start(); 

}

} );



((Button)findViewById(R.id.button2)).setOnClickListener( new View.OnClickListener() {


public void onClick(View v) {

mediaPlayer.stop();

}

} );

}

}

I added to the manifest:
android:screenOrientation=”landscape”
android:configChanges=”keyboardHidden|orientation”

and to the Activity Java file.

@Override public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);     
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
    } 

The layout stays in Landscape and rotation of the orientation does not affect the playing of the app.
