Android 使用 AndroidTestCase 的步骤
1.新建一个类继承 AndroidTestCase
public class TestAudio extends AndroidTestCase {
private AudioManager mAudioManager;
private boolean mUseFixedVolume;
private final static long TIME_TO_PLAY = 2000;
private final static int MP3_TO_PLAY = R.raw.testmp3;
@Override
protected void setUp() throws Exception {
// TODO Auto-generated method stub
super.setUp();
}
public void testmp3(){
MediaPlayer mp = MediaPlayer.create(mContext, MP3_TO_PLAY);
mp.setAudioStreamType(STREAM_MUSIC);
mp.setLooping(true);
mp.start();
try {
Thread.sleep(20*1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
2.修改 AndroidManifest.xml 文件
在application 内部添加
<uses-library android:name="android.test.runner" />
application标签同级的位置添加
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:label="test"
android:targetPackage="com.example.testaudio" />
上面的2个标签的位置很重要,我就是把instrumentation 的位置发错了才会郁闷了的.
具体:
<manifest xmlns:android="
http://schemas.android.com/apk/res/android"
package="com.example.testaudio"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<uses-library android:name="android.test.runner" />
</application>
<!-- 与application标签同级的位置添加 -->
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:label="test"
android:targetPackage="com.example.testaudio" />
</manifest>
