广播接收器不工作 [英] BroadcastReceiver is not working

问题描述

我已经实现这个广播reciever：

I have implemented this broadcast reciever:

public class ServiceManager extends BroadcastReceiver {
    private final String BOOT_ACTION = "android.intent.action.BOOT_COMPLETED";
    private final String BOOT_ACTION_FIRST_LAUNCH = "android.intent.action.PACKAGE_FIRST_LAUNCH";
    private final String BOOT_ACTION_RESTARTED = "android.intent.action.PACKAGE_RESTARTED";

    @Override
    public void onReceive(Context context, Intent intent) {
        // All registered broadcasts are received by this
        String action = intent.getAction();
        if (action.equalsIgnoreCase(BOOT_ACTION) || action.equalsIgnoreCase(BOOT_ACTION_FIRST_LAUNCH) || 
                action.equalsIgnoreCase(BOOT_ACTION_RESTARTED)) {
             // TODO: Action
        } 
    }

}

AndroidManifest.xml中

AndroidManifest.xml

<receiver android:name="package.service.ServiceManager" >
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <action android:name="android.intent.action.PACKAGE_FIRST_LAUNCH" />
        <action android:name="android.intent.action.PACKAGE_RESTARTED" />
    </intent-filter>
</receiver>

该BOOT_COMPLETED行动工作的权利，但是，在PACKAGE_FIRST_LAUNCH和PACKAGE_RESTARTED不工作。我需要我的时候启动我的应用程序来启动我的广播接收器，这就是为什么我使用这些操作。但是，当我启动或重新启动应用程序，接收器不工作。它只有当我重新启动我的手机作品。是否有一些错误我的源？

The BOOT_COMPLETED action is working right, but, the PACKAGE_FIRST_LAUNCH and PACKAGE_RESTARTED are not working. I need to launch my broadcast receiver when I launch my app, that's why I'm using these actions. But, when I launch or restart the app, the receiver is not working. It only works when I restart my mobile phone. Are there something wrong in my source?

推荐答案

从逻辑上看来，一旦你的应用系统启动后运行的第一次 PACKAGE_FIRST_LAUNCH 将播出/重新启动。和 PACKAGE_RESTARTED 如果您的应用程序栈的活动被删除，应播放，然后您的应用程序被点击重新开始（如重启）。

Logically it seems that PACKAGE_FIRST_LAUNCH will be broadcasted once your app is run for the first time after boot/reboot. And PACKAGE_RESTARTED should be broadcasted if your application activity stack is removed and then your app is clicked to start again (like restart).

不过，你可以简单地通过当过你的应用程序启动（可能是从你的第一个活动）广播的自定义操作字符串实现这一点。

However, you may simply achieve this by broadcasting a custom action string when ever your app is launched (perhaps from your first activity).
