android - convert List<ApplicationInfo> to String[ ] -


i need convert list string[ ]. how that?

i tried that: 

 packagemanager packagemanager = getpackagemanager();     list<applicationinfo> liste_aller_anwendungen = packagemanager.getinstalledapplications(packagemanager.get_meta_data);      string[] strings = liste_aller_anwendungen.toarray(new string[liste_aller_anwendungen.size()]);

but produces following logcat errors: 

java.lang.arraystoreexception: source[0] of type android.content.pm.applicationinfo cannot stored in destination array of type java.lang.string[]         @ java.lang.system.arraycopy(native method)         @ java.util.arraylist.toarray(arraylist.java:523)         @ de.gestureanywhere.hintergrundservice.ongestureperformed(hintergrundservice.java:152)         @ android.gesture.gestureoverlayview.fireongestureperformed(gestureoverlayview.java:729)         @ android.gesture.gestureoverlayview.access$400(gestureoverlayview.java:55)         @ android.gesture.gestureoverlayview$fadeoutrunnable.run(gestureoverlayview.java:744)         @ android.os.handler.handlecallback(handler.java:733)         @ android.os.handler.dispatchmessage(handler.java:95)         @ android.os.looper.loop(looper.java:136)         @ android.app.activitythread.main(activitythread.java:5034)         @ java.lang.reflect.method.invokenative(native method)         @ java.lang.reflect.method.invoke(method.java:515)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:795)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:611)         @ dalvik.system.nativestart.main(native method)

thanks

first of all:

<t> t[]     toarray(t[] a) returns array containing of elements in list in proper sequence (from first last element); runtime type of returned array of specified array.

so notice trying store list of applicationinfo in list of string, not possible. way so:

string[] strings =  new string[liste_aller_anwendungen.size()]; for(int = 0; < liste_aller_anwendungen.size(); i++) {     strings[i] = liste_aller_anwendungen[i].tostring(); // or whatever want, needs `string` }
