其他应用程序的Android Broadcastreceiver安装/删除无法正常工作 [英] Android Broadcastreceiver for other apps install/delete not working

问题描述

我有一个Broadcastreceiver，可以检测其他应用的安装或删除.

I have a Broadcastreceiver to detect other apps installs or deletion.

这是我的Java

public class AppListener extends BroadcastReceiver {

    @Override
    public void onReceive(Context var1, Intent var2) {
        // TODO Auto-generated method stub

        Log.d("AppTag", "Received!");
}
}

这是我的清单

<receiver android:name=".AppListener">
        <intent-filter android:priority="999">
            <category android:name="android.intent.category.DEFAULT" />
            <action android:name="android.intent.action.PACKAGE_ADDED" />
            <action android:name="android.intent.action.PACKAGE_REMOVED" />
            <action android:name="android.intent.action.PACKAGE_CHANGED" />
            <data android:scheme="package"/>
        </intent-filter>
    </receiver>

但是无论何时我安装或删除应用程序，都不会发生！

But whenever I install or delete an app nothing occurs!

推荐答案

您正在尝试收听 ACTION_PACKAGE_ADDED 和 ACTION_PACKAGE_REPLACED 之类的广播.这对于Android 7.1及更低版本来说很好.在Android 8.0+上，您不能在清单中注册这些广播，如大多数隐式广播均被禁止.

You are trying to listen to broadcasts like ACTION_PACKAGE_ADDED and ACTION_PACKAGE_REPLACED. That is fine for Android 7.1 and lower. On Android 8.0+, you cannot register for those broadcasts in the manifest, as most implicit broadcasts are banned.

相反，您需要调用 PackageManager 上> getChangedPackages()，例如通过 WorkManager .这不会为您提供实时结果，但是在Android 8.0+上不再可以选择实时结果.

Instead, you need to call getChangedPackages() on PackageManager periodically, such as via WorkManager. This will not give you real-time results, but real-time results are no longer an option on Android 8.0+.
