意图PACKAGE_ADDED不注册 [英] Intent PACKAGE_ADDED not registering

问题描述

您好，我试图检测应用程序安装的，这样我可以做一些分析上的应用程序，我用这个例子，我发现计算器听从我目前的应用程序包安装，但什么也没有发生在我的logcat中。

 无效registerReceiver（）{
    IntentFilter的过滤器=新的IntentFilter（Intent.ACTION_PACKAGE_ADDED）;
    filter.addAction（Intent.ACTION_PACKAGE_REMOVED）;
    filter.addAction（Intent.ACTION_PACKAGE_CHANGED）;
    filter.addDataScheme（包）;

}

公共无效的onReceive（上下文的背景下，意图意图）{
    串actionStr = intent.getAction（）;
    如果（Intent.ACTION_PACKAGE_ADDED.equals（actionStr））{
        乌里数据= intent.getData（）;
        字符串PKGNAME = data.getEn codedSchemeSpecificPart（）;
        //把手包加...
        Log.i（记录服务，包名称）;

    }

}

解决方案

由于由于Android 3.1的广播行为的改变，你的应用程序必须在启动前就可以收到应用程序安装/拆卸意图。见kabuko的回答<一href="http://stackoverflow.com/questions/8515310/broadcast-receiver-for-package-added-not-working-from-android-3-1-onwards">in这个线程。

下面的接收器可以接收的是Android 4.0的设备（我在应用程序的活动，首先启动的活动，即应用程序也会启动，则接收器可以接收广播）的我。

 ＆LT;接收机器人：名称=。MyReceiver＆GT;
    ＆LT;意向滤光器＆gt;
        ＆lt;作用机器人：名称=android.intent.action.PACKAGE_ADDED/＆GT;
        ＆lt;作用机器人：名称=android.intent.action.PACKAGE_CHANGED/＆GT;
        ＆lt;作用机器人：名称=android.intent.action.PACKAGE_REMOVED/＆GT;
        ＆lt;数据机器人：计划=包/＆GT;
    ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
 

（一些应用程序运行一个虚拟的粘滞服务，以保持应用程序活着，让他们可以得到一定的广播）

Hello i am trying to detect application installed so that i can do some analysis on the application and i am using this example i found on stackoverflow to listen for package installs from my current application but nothing is happening in my logcat.

void registerReceiver() {
    IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
    filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
    filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
    filter.addDataScheme("package");

}

public void onReceive(Context context, Intent intent) {
    String actionStr = intent.getAction();
    if (Intent.ACTION_PACKAGE_ADDED.equals(actionStr)) {
        Uri data = intent.getData();
        String pkgName = data.getEncodedSchemeSpecificPart();
        //handle package adding...
        Log.i("Logging Service", pkgName);

    }

}

<receiver android:name="RealTimeActivity">
    <intent-filter>
   <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.PACKAGE_ADDED"  />
    <action android:name="android.intent.action.PACKAGE_CHANGED" />
    <action android:name="android.intent.action.PACKAGE_INSTALL" />
    <action android:name="android.intent.action.PACKAGE_REMOVED" />
    <action android:name="android.intent.action.PACKAGE_REPLACED" />
    </intent-filter>
 </receiver>


<uses-permission android:name="android.permission.BROADCAST_PACKAGE_ADDED" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_CHANGED" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_REMOVED" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_INSTALL" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_REPLACED" />

解决方案

Due to a broadcast behavior change since Android 3.1, your app must be started before it can receive the app installation/removal intents. See kabuko's answer in this thread.

The following receiver works for me on a Android 4.0 device (I have an activity in the app, first start the activity i.e. the app is also started, then the receiver can receive the broadcast).

<receiver android:name=".MyReceiver">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_ADDED" />
        <action android:name="android.intent.action.PACKAGE_CHANGED" />
        <action android:name="android.intent.action.PACKAGE_REMOVED" />
        <data android:scheme="package" />
    </intent-filter>
</receiver>

(some apps run a dummy sticky service to keep the app process alive, so that they can receive certain broadcasts)
