jar - App works fine in android 2.3.7 and not in 4.1.2 -

i have app works fine in android 2.3.4, 2.3.6 , 2.3.7 doesn´t in android 4.1.2 or 4.2.2 (i have no more devices)

the app calls jar file returns result, when test app in 2.3.7 make call jar , takes result when android 4.1.2 forces close. it´s quite weird because difference os because app same.

the jar file makes call internet, don´t think mistake

thanks again everybody!

the jar file makes call internet, don´t think mistake

=> sorry dude problem here, said app working fine in < 2.3 versions not in >2.3, reasons behind failure networkonmainthreadexception.

now, why exception being raised whenever run app in >2.3 version device?

=> networkonmainthreadexception occurs whenever application attempts perform networking operation on main thread.

solutions:

below 2 solutions resolve issue:

1) standard way make webservice call implementing asynctask.

2) lazy way of handling turn check of:

strictmode.threadpolicy policy = new strictmode.threadpolicy.builder().permitall().build(); strictmode.setthreadpolicy(policy);
