未收到ACTION_MY_PACKAGE_REPLACED

Question

当我的应用程序更新或树脂安装时,我正在使用ACTION_MY_PACKAGE_REPLACED来接收.我的问题是从未触发事件(我尝试过Eclipse和真实设备).这就是我做的:

表现:

<receiver android:name=".MyEventReceiver" >
    <intent-filter android:priority="1000" >
        <action android:name="android.intent.action.ACTION_MY_PACKAGE_REPLACED" />
    </intent-filter>
</receiver>

码:

public class MyEventReceiver extends BroadcastReceiver
{  
   @Override public void onReceive(Context context, Intent intent)
   {  
      if ("android.intent.action.ACTION_MY_PACKAGE_REPLACED".equals(intent.getAction())) 
      {  //Restart services
      }
   }      
}

这段代码很简单,实际上我使用了其他事件,比如BOOT_COMPLETED和其他事件,它们可以工作但ACTION_MY_PACKAGE_REPLACED.谢谢.

出于某种原因,谷歌开发人员(名为"Dianne Hackborn")认为可以单独注册当前应用程序的PACKAGE_REPLACED意图(链接在这里).

但是,我找不到任何正确的方法,所以我做了一个妥协:它将使用最新的API.

遗憾的是,我无法找出无法调试的原因,但它确实有效(如果您愿意,可以写入日志).

这是代码:

表现:

    <receiver
        android:name=".OnUpgradeBroadcastReceiver"
        android:enabled="@bool/is_at_most_api_11" >
        <intent-filter>
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <data android:scheme="package" />
        </intent-filter>
    </receiver>
    <receiver
        android:name=".OnUpgradeBroadcastReceiver"
        android:enabled="@bool/is_at_least_api_12" >
        <intent-filter>
            <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
        </intent-filter>
    </receiver>

    <item name="is_at_least_api_12" type="bool">false</item>

OnUpgradeBroadcastReceiver.java

public class OnUpgradeBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {
        if (VERSION.SDK_INT <= VERSION_CODES.HONEYCOMB
                && !context.getPackageName().equals(intent.getData().getSchemeSpecificPart())) {
            android.util.Log.d("AppLog", "other apps were upgraded");
            return;
        }
        android.util.Log.d("AppLog", "current app was upgraded");

该接受的答案不工作了与Android工作室1.0+因为清单合并的问题,因为看到这里.完全基于android开发人员的回答,我用以下实现修复了这个问题:

AndroidManifest.xml中:

<receiver android:name=".UpdateReceiver$LegacyUpdateReceiver" android:enabled="@bool/shouldUseActionPackageReplaced" >
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_REPLACED" />
        <data android:scheme="package" />
    </intent-filter>
</receiver>
<receiver android:name=".UpdateReceiver" android:enabled="@bool/shouldUseActionMyPackageReplaced" >
    <intent-filter>
        <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
    </intent-filter>
</receiver>

/res/values/resources.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="shouldUseActionPackageReplaced">true</bool>
    <bool name="shouldUseActionMyPackageReplaced">false</bool>
</resources>

/res/values-v12/resources.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="shouldUseActionPackageReplaced">false</bool>
    <bool name="shouldUseActionMyPackageReplaced">true</bool>
</resources>

UpdateReceiver.java:

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

public class UpdateReceiver extends BroadcastReceiver
{
    public static class LegacyUpdateReceiver extends BroadcastReceiver
    {
        @Override
        public void onReceive(Context context, Intent intent)
        {
            if (intent != null && intent.getData() != null && context.getPackageName().equals(intent.getData().getSchemeSpecificPart()))
            {
                onUpdate(context);
            }
        }
    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        onUpdate(context);
    }

    public static void onUpdate(Context context)
    {
        Log.d("LOG", "Current app updated");
    }
}

从所有用户那里获取信息我可以用这种方式解决我的情况.所有这些都是正确的,没有什么要注意的事项:

在清单中:

    <receiver android:name=".MyEventReceiver" >
        <intent-filter android:priority="1000" >
            <!--other actions I need-->
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <data android:scheme="package"/>
        </intent-filter>
    </receiver>

和代码:

public class MyEventReceiver extends BroadcastReceiver
{     
    @Override public void onReceive(Context context, Intent intent)
    {  
       if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())) 
       {   if(intent.getData().getSchemeSpecificPart().equals(context.getPackageName()))
           {  //Restart services.
           }
       }
    }      
}

在我的Android版本(2.3 Gingerbread)中,我无法使用MY_PACKAGE_REPLACED,但是我们使用PACKAGE_REPLACED解决了(会建议更换任何应用),但询问是否是我们的:

 if(intent.getData().getSchemeSpecificPart().equals(context.getPackageName()))
 {
 }

谢谢大家

我只想在这里添加我自己的两便士,因为我有问题让它工作并调试它..我正在使用Lollipop设备:

这是我使用的代码:

    <receiver android:name=".services.OnUpdateReceiver">
        <intent-filter>
            <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
        </intent-filter>
    </receiver>    

要调试它,您需要确保已在手机上安装了更新,只需通过Eclipse调试就可以了,并且至少打开了一次应用程序,然后您可以简单地编辑调试配置:

eclipse > run > debug configurations > launch action (do nothing) > then F11 like normal

我确认它是通过写一个小文件到SD卡
