我有一个应用程序,它保存设备上安装的内部开发应用程序的日志.安装后,将调用Intent.PACKAGE_ADDED的广播接收器,并使用以下代码记录包名称:

public class NewInstallReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle b = intent.getExtras();
        int uid = b.getInt(Intent.EXTRA_UID);
        String[] packages = context.getPackageManager().getPackagesForUid(uid);

        ApplicationService appService = new ApplicationService(context);
        appService.ApplicationInstalled(packages);
    }
}

我面临的问题是当使用Intent.PACKAGE_REMOVED的广播接收器时,通过唯一ID(UID)对包的所有引用都会返回空信息(如您已经卸载的那样,正如您所期望的那样).我有一个临时解决方案,但它不是很优雅,对于下一个版本,我希望有更清晰的代码.代码应如何工作的示例:

public class RemoveApplicationReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent) 
    {
        Bundle b = intent.getExtras();
        int uid = b.getInt(Intent.EXTRA_UID);
        String[] packages = context.getPackageManager().getPackagesForUid(uid);

        ApplicationService appService = new ApplicationService(context);
        appService.ApplicationRemoved(packages);
    }

}

所以回顾一下,问题是:

删除程序后,如何在广播接收器中为Intent.PACKAGE_REMOVED引用包名称.

谢谢

创建BroadcastReceiver,在安装/卸载任何应用程序时显示应用程序名称和版本号.但我得到包名intent.getData().但是当我试图使用packagemanager找到该应用程序的名称时,它会在所有安装/卸载/替换的情况下抛出异常.可能存在的问题是什么？如何解决这个问题？

码:

    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.content.pm.ApplicationInfo;
    import android.content.pm.PackageManager;
    import android.widget.Toast;

public class ApplicationStatusNotification extends BroadcastReceiver {

    /**
     * This method receives message for any application status(Install/ Uninstall) and display details.
     */
    @Override
    public void onReceive(Context context, Intent intent) {

        // Get application status(Install/ Uninstall)
        boolean applicationStatus = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
        String toastMessage = null;

        // Check if the application is install or uninstall and display the message accordingly
        if(intent.getAction().equals("android.intent.action.PACKAGE_INSTALL")){
            // Application Install
            toastMessage = "PACKAGE_INSTALL: …
