PACKAGE_REMOVED和放大器;然后PACKAGE_ADDED与PACKAGE_REPLACED意图动作射击沿 [英] PACKAGE_REMOVED & then PACKAGE_ADDED are fired along with PACKAGE_REPLACED Intent Action

问题描述

所有我想要做的就是更新我的每个安装及放列表;卸载但不会在包装更换。所以主要的问题是，安装和放大器;卸载意图是每个替换操作启动。

All I am trying to do is update my list on each Install & Uninstall but not on Package Replace .So the main problem is that Install & Uninstall intents are launched on each Replace action.

所以， 为此，我实现了一个BroadcastReciever如下

So For this I have implemented a BroadcastReciever as below

<receiver android:name =".IntentReceiverTest.AppReciever">
  <intent-filter>
         <action android:name="android.intent.action.PACKAGE_REMOVED"/>
         <action android:name="android.intent.action.PACKAGE_REPLACED"/>
         <action android:name="android.intent.action.PACKAGE_ADDED"/>
         <data android:scheme="package"/> 
  </intent-filter>
</receiver> 

在每次更换我得到3广播用行动

On each Replace I get 3 broadcasts with actions

• 首先是 PACKAGE_REMOVED 这触发鸭preciever
• 然后在 PACKAGE_ADDED 这再次触发鸭preciever
• 然后几秒钟后的 PACKAGE_REPLACED 这再次触发鸭preciever

• First with PACKAGE_REMOVED which fires AppReciever
• then after PACKAGE_ADDED which again fires AppReciever
• And then after few seconds PACKAGE_REPLACED which again fires AppReciever

所以，请提出更好的办法只能赶上替换操作

So please suggest any better way to catch only Replace Action

或

办法停止$ P $由于PACKAGE_REMOVED和PACKAGE_ADDED pviously推出服务操作。

推荐答案

只是检查 intent.getBooleanExtra（Intent.EXTRA_REPLACING，FALSE）：

if (!intent.getAction().equals(Intent.ACTION_PACKAGE_REPLACED) &&
    intent.getBooleanExtra(Intent.EXTRA_REPLACING, false))
    return;
