3.配置文件:
Java代码
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".TestServiceHolder" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true" android:name=".TestService"
android:process=":remote" />
</application>
