我想打一个应用程序时，安装或删除其它应用程序，可以接收广播。 我的code

I want to make an app that can receive broadcast when another app installed or removed. my code

在manifset：

<receiver android:name=".apps.AppListener">
    <intent-filter android:priority="100">
         <action android:name="android.intent.action.PACKAGE_INSTALL"/>
         <action android:name="android.intent.action.PACKAGE_ADDED"/>  
         <action android:name="android.intent.action.PACKAGE_REMOVED"/>
    </intent-filter>
</receiver>

在的AppListener：

in AppListener:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class AppListener extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent arg1) {
    // TODO Auto-generated method stub
    Log.v(TAG, "there is a broadcast");
    }
}

但我不能接收任何广播。我觉得这个问题是关于permissins，任何想法？

but I can't receive any broadcast. I think this problem is about permissins, any idea?

感谢帮助。

推荐答案

在你的清单：

<receiver android:name=".apps.AppListener">
    <intent-filter android:priority="100">
         <action android:name="android.intent.action.PACKAGE_INSTALL"/>
         <action android:name="android.intent.action.PACKAGE_ADDED"/>  
         <action android:name="android.intent.action.PACKAGE_REMOVED"/>
    </intent-filter>
</receiver>

意向过滤器标签之前添加行

Add the line before the intent-filter tag

<data android:scheme="package"/>

所以，你的表现应该是这样的：

So your manifest should look like this:

<receiver android:name=".apps.AppListener">
    <intent-filter android:priority="100">
         <action android:name="android.intent.action.PACKAGE_INSTALL"/>
         <action android:name="android.intent.action.PACKAGE_ADDED"/>  
         <action android:name="android.intent.action.PACKAGE_REMOVED"/>
         <data android:scheme="package"/> 
    </intent-filter>
</receiver>

我不知道有关PACKAGE_REMOVED意图，如果它实际上是可用的。

Am not sure about the PACKAGE_REMOVED intent in that if its actually is available.
