android - App not working on AVD, only actual devices -

i'm trying test app, having no luck emulators. i've tried few different avd's , bluestacks. due way mount virtual sdcard, app not finding cache directory expected. however, when run same app on 2 different android phones, seems work properly. facing problem made me think there must better way of referencing folder i'm looking for.

i'm using in oncreate:

    // check if application exists     (int = 0; < list.size(); i++) {         if (list.get(i).packagename.equals("com.someapphere")) {             v.settext("application found");             break;         } else {             v.settext("application not found");         }     }      if (v.gettext() == "application found") {         // check cache usage         final file datastore = environment.getexternalstoragedirectory();         try {             file tcache = new file(datastore.getabsolutepath()                  + "/android/data/com.someapphere/cache");             long tcachesize = foldersize(tcache);              if (tcachesize == 0) {                  v2.settext(" nothing do");             } else {               // start async task - delete files               ...             }         } catch(exception e) {               v2.settext(" cache not found");         }     } 

i took out of other irrelevant stuff i'm doing here, rest should replicate issue. if it's not obvious, i'm still quite new programming.

text can't compared '=='.

you should try this:

v.gettext().tostring().equalsignorecase("application found"); 

and not working in emulator may because don't have sd card support in emulator.

in eclipse go in menu window – android sdk , avg manager select virtual devices select avd name need install sd card click on edit button in open dialog go sd card – size: , write 500 press button edit avd run avd emulator

hope helps!!
