javascript - App crashes while debugging, after installed Android 6.0.1 -

this might sound weird one. beginner coder , right making app has login/register activities. worked fine on samsung galaxy s3 (android version 4.3.), week ago installed cyanogenmod , have android version 6.0.1.

here problem - if run app opens popup alert "unfortunately, myfirstapp has stopped.", , when click ok button opens login window, should. after try enter credentials login or register shows default error message cannot connect server. tried on second phone, same model samsung galaxy s3, android 4.3 works without problem.

i tried debugging app crashes immediately, console message:

connected target vm, address: 'localhost:8613', transport: 'socket' disconnected target vm, address: 'localhost:8613', transport: 'socket' 

my appconfig:

// default configuration emulator/device urls // private static string base_url = "http://10.0.2.2/myfirstapp/"; private static string base_url = "http://192.168.0.103/myfirstapp/";  // server user login url public static string url_login = base_url + "login.php";  // server user register url public static string url_register = base_url + "register.php"; 

i have enabled debugging on phone.

most problem here new android permission model. since api 23 (android 6.0) have ask user permissions directly before using features need. should either target api 22 or below or implement run time permission. hundred percent sure causes problem should view logs (android monitor -> logcat, , don't forget clear tag text box, may choose "error" level see errors).
