Hi,
I am writing a Instrumnetation using the
AvtivityInstrumnetationTestCase class and a test case about play
music. When I execute the test case, it is work fine. But there the
problem is the application play nothing. The Activity appear one
moment then back to HOME screen.
Reference my code:
File: MainActivity.java
-----------------------------------------------------------------
package com.android.testapp;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void PlayMyMusic(){
//----Pre set----
AudioManager am=(AudioManager)
getApplicationContext().getSystemService(AUDIO_SERVICE);
try {
//Utility.PlayMusic("/storage/sample.mp3");
MediaPlayer mp = new MediaPlayer();
Log.e("debug","media player set data source...");
mp.setDataSource("/storage/sample.mp3");
Log.e("debug","media player set loop...");
mp.setLooping(true);
Log.e("debug","media player prepare...");
mp.prepare();
Log.e("debug","media player start...");
mp.start();
Log.e("debug","media player started...");
// i.e. react on the end of the music-file:
mp.setOnCompletionListener(new OnCompletionListener(){
// @Override
public void onCompletion(MediaPlayer arg0) {
// File has ended !!!
}
});
} catch (Exception e) {
Log.e("debug","media player error..."+e.toString());
// TODO Auto-generated catch block
e.printStackTrace();
}
}
File:PlayMyMusic.java
-----------------------------------------------------------------
package test;
import com.android.testapp.MainActivity;
import android.test.ActivityInstrumentationTestCase2;
import android.test.suitebuilder.annotation.MediumTest;
public class PlayMyMusic extends
ActivityInstrumentationTestCase2<MainActivity> {
public PlayMyMusic() {
super("com.android.testapp", MainActivity.class);
}
public PlayMyMusic(String pkg, Class<MainActivity> activityClass) {
super(pkg, activityClass);
}
@MediumTest
public void testPlayMyMusic() throws Exception {
getActivity().PlayMyMusic();
}
}
File:TestApp.Manifest
-----------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>

</manifest>
-----------------------------------------------------------------
Type below command to run it.
>adb shell am instrument -e class test.PlayMyMusic -w
>com.android.testapp/android.test.InstrumentationTestRunner
-----------------------------------------------------------------
Command logcat to get the log
>adb logcat debug:E *:S
E/debug (15281): media player set data source...
E/debug (15281): media player set loop...
E/debug (15281): media player prepare...
E/debug (15281): media player start...
E/debug (15281): media player started...
-----------------------------------------------------------------
I get the output "OK (1 test)". This is so curious. Normally if it is
a pass test, I will get the output "OK (2 test)".
test.PlayMyMusic:.
Test results for InstrumentationTestRunner=.
Time: 3.625
OK (1 test)
Help me,
Perrot
