android - Activity get's recreated although I call finish -

-

background

i use helper activity determine when floating widget (placed in windowmanager) opens activity, need hide floating widget then...

therefore create transparent activity, checks in onpause if screen turned off or not. if not, assume activity opened floating widget.

problem

opening recent apps lead hide floating widget , finish helper activity, desired.

but pressing afterwards, recreates helper activity. , helper activity shown in recent apps (although finished it).

usage , log

i open activity @ 1 place following:

l.d(this, "helperactivity created"); intent = new intent(getcontext(), helperactivity.class); i.addflags(intent.flag_activity_new_task); i.putextra("sidebarid", msidebar.getid()); getcontext().startactivity(i);

and log says:

[sidebarview-241]   helperactivity created [helperactivity-30] oncreate: 1

<< pressing recent apps button on phone >> 

[helperactivity-69] new top [helperactivity-45] onsidebarcloseevent [helperactivity-36] ondestroy

<< showing recent apps >> 

[helperactivity-30] oncreate: 1

code

manifest:

 <activity         android:name=".activities.helperactivity"         android:configchanges="orientation|screensize"         android:excludefromrecents="true"         android:nohistory="true"         android:theme="@style/theme.transparent"         android:launchmode="singletask" />

class:

    public class helperactivity extends appcompatactivity {      private boolean mdocheck = true;      @override     public void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         busprovider.getinstance().register(this);          setcontentview(r.layout.activity_helper);          long sidebarid = -1;         if (getintent().getextras().containskey("sidebarid"))             sidebarid = getintent().getextras().getlong("sidebarid");          l.d(this, "oncreate: " + sidebarid);     }      @override     public void ondestroy()     {         l.d(this, "ondestroy");          busprovider.getinstance().unregister(this);         super.ondestroy();     }      @subscribe     public void onsidebarcloseevent(sidebarcloseevent event)     {         l.d(this, "onsidebarcloseevent");          mdocheck = false;         finish();     }      @override     public void onpause()     {         super.onpause();          if (!mdocheck)             return;          // pause + screenon => andere activity on top!         powermanager pm = (powermanager) getsystemservice(power_service);         boolean screenon;         if (build.version.sdk_int >= build.version_codes.kitkat_watch)             screenon = pm.isinteractive();         else             screenon = pm.isscreenon();          if (screenon)         {             l.d(this, "new top");             busprovider.getinstance().post(new sidebarcloseevent(null, true, false));         }     } }

current solution

i worked out following solution:

in oncreate use following:

boolean launchedfromhistory = (flags & intent.flag_activity_launched_from_history) == intent.flag_activity_launched_from_history; if (launchedfromhistory)     finish();

this seems work... still, maybe has comment solution or knows better...
