Android异常总结---Test run failed:Unable to find instrumentation target package

本例为以下DemoDao类进行单元测试
----------------新建DemoDao.java--------------
package com.neter.test.dao;

import android.util.Log;

public class DemoDao{

public void save(){
Log.i("DemoDao", "用来测试的方法");
}
}
----------------新建DemoDaoTest.java--------------
package com.neter.test.dao;

import android.test.AndroidTestCase;
import android.util.Log;



public class DemoDaoTest extends AndroidTestCase {

public void testSave() {
new DemoDao().save();
Log.i("DemoDaoTest", "测试");
}

}
-------------------------------AndroidManifest.xml--------------------------
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=" http://schemas.android.com/apk/res/android"
package="com.neter.test.dao"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="android.test.runner"/>
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.neter.test.dao" android:label="Testing"></instrumentation>
</manifest>
上面配置文件中
MainActivity为android程序入口,请自已新建代码略
<uses-library android:name="android.test.runner"/>不可修改
android:name="android.test.InstrumentationTestRunner不可修改
android:label="Testing"可不写
如出现Test run failed:Unable to find instrumentation target package
是因为 android:targetPackage="com.neter.test.dao" 必须和
<manifest xmlns:android=" http://schemas.android.com/apk/res/android"
package="com.neter.test.dao"
package相同的包名
