This is my json parser code:

and Important thing is if i convert into apk file and run the apk file into the devices which was i used to debug the application that devices works fine (i.e that apk able to run on the deveice) but other devices it will not work(i.e it will not open or not run on the device)

can anyone please solve this issue?

Answer 1

The question is old, but same problem here after several years. I solved by "lowering" the linking option to "sdk assemblies only" in the release configuration.

The linking option is tricky. "sdk and user assemblies" does not do what it may seem (adding user assemblies). However, it searches for unused code also in user assemblies, but the linker may misjudge code outside the sdk and remove necessary code.

Answer 2

Add this line in Proguard File

-keep class org.json.** { *;}

Proguard obfuscated the JSON Object class. In debug builds, Proguard is generally disabled so the problem doesn't occur.
