Ein Android Splash Screen Tutorial (mit mp3 Sound)

Es ist immer gut, wenn eine Android App uns mit einen Splash Screen begrüßt. Hier ein Tutorial dafür:

Der splash.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/back"
>
</LinearLayout>

Der Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="de.worldling"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" />

<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".Splash"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Sound1"
android:label="@string/app_name" >
<intent-filter>
<action android:name="de.worldling.SOUND1" />

<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

</manifest>

Und die Java Classe, splash.java:

package de.worldling;

import java.io.IOException;

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;

public class Splash extends Activity {

	MediaPlayer mp;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.splash);

		mp = MediaPlayer.create(Splash.this, R.raw.sound1);
		mp.start();

		Thread timer = new Thread() {
			public void run() {
				try {
					sleep(5000);// 5 seconds
				} catch (InterruptedException e) {
					e.printStackTrace();
				} finally {
					Intent openStartingPoint = new Intent("de.worldling.SOUND1");
					startActivity(openStartingPoint);
				}
			}
		};
		timer.start();
	}

	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		super.onPause();
		mp.release();
		finish();
	}

}
