测试后，当我试图卸载防病毒，防病毒，促使我说，'你确定要删除这个应用程序吗？。
这提示屏幕由防病毒应用程序产生的。该屏幕后，我得到了系统的提示与确定和取消按钮。所以，这提示放入防病毒应用程序。

After Testing when I have tried to uninstall that Antivirus,Antivirus has prompted me that 'are you sure you want to remove this application?'.

推荐答案

我添加下面的意图过滤器，现在我收到来选择活动的对话框。我想你应该有这个过滤器来显示你的活动（特别是与过滤器的数据部分）播放。                         

I've added the following intent-filter and now I receive the dialog to chose activity. I think you should play with this filter to display your activity (especially with data part of the filter).

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".UninstallIntentActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.DELETE" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="package"  />
        </intent-filter>



    </activity>

</application>
