google maps - NullPointerException error, in android.text.Editable android.widget.EditText.getText() -
i developing android apps. had problem. implemented 2 fragments in floating bar. , each floating bar button connected moving map , print listing. when clicked going map, print google maps normally. , in state, press button move home screen in smartphone. , when run app, print google map. but, in stae, if clicked on google location search @ top in application, app crash...
the error message follows: 08-20 09:56:48.698 16761-16761/songjong.com.seongnamgiftcard e/androidruntime: fatal exception: main process: songjong.com.seongnamgiftcard, pid: 16761 java.lang.nullpointerexception: attempt invoke virtual method 'android.text.editable android.widget.edittext.gettext()' on null object reference @ com.google.android.gms.location.places.ui.placeautocompletefragment.zzwc(unknown source) @ com.google.android.gms.location.places.ui.placeautocompletefragment.zzb(unknown source) @ com.google.android.gms.location.places.ui.zzc.onclick(unknown source) @ android.view.view.performclick(view.java:6261) @ android.widget.textview.performclick(textview.java:11159) @ android.view.view$performclick.run(view.java:23752) @ android.os.handler.handlecallback(handler.java:751) @ android.os.handler.dispatchmessage(handler.java:95) @ android.os.looper.loop(looper.java:154) @ android.app.activitythread.main(activitythread.java:6776) @ java.lang.reflect.method.invoke(native method) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:1496) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:1386)
