android:来自市场活动的回应

Question

我正在尝试制作一个应用程序,打开所选应用程序的Android市场页面,并让用户下载它.我已经使用以下意图打开市场.

  Intent intent = new Intent (Intent.ACTION_VIEW);
    intent.setData (Uri.parse ("market://details?id=" + PackageName ));
    intent.setFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivityForResult (intent, 13);

但我总是在onActivityResult.StackTrace中得到结果码0:

I/ActivityManager(   79): Starting activity: Intent { act=android.intent.action.VIEW dat=market://details?id=com.google.android.apps.unveil flg=0x10000000 cmp=com.an
droid.vending/.AssetInfoActivity }
W/ActivityManager(   79): Activity is launching as a new task, so cancelling activity result.

我想要的是市场给我一些回复,用户下载了应用程序或刚刚取消.

编辑: @CommonsWare我试图在这里访问添加的包但是无法确定从ACTION_PACKAGE_ADDED的额外内容中获取packagename的关键

public class ServiceReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
    //Do this when the system sends the intent
    Bundle b = intent.getExtras();
    String packagename = b.get(?);   //cant figure what should be key to get packagename //from extras
    }

}

Answer 1

Android Market未设置为支持startActivityForResult().另外,请记住下载和安装是异步发生的(即,用户单击"安装",下载发生在后台,并通过它完成安装Notification).
