Android单元测试Unable to find instrumentation target package的问题

-------------------------------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
