BroadcastReceiver无法正常工作

Question

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

<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>

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?

Answer 1

FYI: PACKAGE_FIRST_LAUNCH is sent to the installer package, ie whatever you used to install the application - for most end users that would be Android Market.

Oh, and for "PACKAGE_RESTARTED", break that one out into its own <intent-filter> and add a

<data android:scheme="package"/>

since that one comes with an URI and an explicit scheme.

Answer 2

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).

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

Answer 3

The intent android.intent.action.PACKAGE_FIRST_LAUNCH is introduced in Android API Level 12. If you are using lesser API Level it will not work. So change your project settings accordingly.

Manifest:

...
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></>
...
<receiver android:name=".AutoStart">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"></action>
    </intent-filter>
</receiver>
...

Receiver:

package YourPackage;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AutoStart extends BroadcastReceiver
{   
    @Override
    public void onReceive(Context context, Intent intent)
    {   
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
        {
            // Your code
        }
    }
}
