Question

I have downloaded Application Protection application from market. It allows me to protect to open any application with password.

i.e. 我已保护“Lost Application with Application Protection”。

现在,我开始联系Lost App。我在Logcat中发现以下记录。

1-start: Intent{ act=android.intent.action.MAIN cat=[android.intent. category. LAUNCHER] flg=0x10200000 cmp=com.android.linkionlost/.Connection Lost } from pid 5746

2-start: Intent{flg=0x10000000 cmp=com.ruimaninfo.approtect/.ui.Screen Locker } from pid 5494

这首先意味着我的申请启动,在plica子保护启动后,它自行开展活动。

因此,我的问题是:

How Application protection(Downlaode from market) know that which package is launched? and As programmer how can we know the same thing?

谢谢。

您可以发现,活动管理员正在推出哪些一揽子计划。

ActivityManager am = (ActivityManager) getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();
String ClassName = am.getRunningTasks(1).get(0).topActivity.getClassName();

You can make one background service which has a timer task of 100 seconds 
and put this code in timertask which prints log at every 100 seconds that which package is launching
