debugging - Android app be blank without run it from debug in Lollipop 5.0 -

i have problem developing android app in lollipop. using nexus 7 (2012).

if app run eclipse (run debug) work ok. if open in app screen (on phone), show blank screen (the actionbar , drawer still working) main content (i use fragments) blank

edited :

these code in mainactivity loading fragment content :

mstacks = new hashmap<string, stack<fragment>>();     mstacks.put(appconstant.test_fragment, new stack<fragment>());      bundle bundle = getintent().getextras();     currentmenu = appconstant.test_fragment;      if (bundle != null) {         currentmenu = bundle.getstring(baseappconstant.intent_al_screeen_name_extra);     }      if (currentmenu != null) {         if (currentmenu.equals(appconstant.test_fragment))            pushfragments(new listfragment(), false, true);     }
