}

There is a Class that is not found at release time.

Also, I have applied below solution: 1) Android: java.lang.NoClassDefFoundError on the release APK 2) Android: NoClassDefFoundError only on release build

Try disabling proguard for your release build or you can add a rule in your proguard file to keep the Activity for which you are getting this error — Shivam Pokhriyal, Jul 06 '19 at 11:18
as @ShivamPokhriyal suggested, try after disabling proguard. — Abhay Koradiya, Jul 06 '19 at 11:20
Also, I have disabled Proguard at release build and its working But i want to apply Proguard. — axita.savani, Jul 06 '19 at 11:21
@axita.savani I think there is an issue in resource file fetching. — VIISHRUT MAVANII, Jul 06 '19 at 11:27
Sorry, I am not getting you, Can you please explain in Detail? @VishrutMavani — axita.savani, Jul 06 '19 at 11:29

minifyEnabled and shrinkResources are very important in your build.gradle file if you want to decrease the size of generated apk for specific build types, ideally the ‘release’ type.

minifyEnabled shrinks code by deleting unused code and references.

shrinkResources on the other hand removes unused resource files from /res folder that are not referenced in the code.

you have to use this code

res = getResources().getIdentifier(filter_none, "string", getPackageName());

instead of

R.string.filter_none

Now, if you refer to a resource dynamically by using the Resources.getIdentifier() the method then since unreferenced resources were removed, unexpected behavior will occur.

So to avoid this, when accessing resource dynamically, use this trick as explained in Android User Guide using this example

String name = String.format("img_%1d", angle + 1);
res = getResources().getIdentifier(name, "drawable", getPackageName());

Thank You, Bro I have applied solution and it's working – S_i_l_e_n_t C_o_d_e_r Jul 06 '19 at 11:49 — S_i_l_e_n_t C_o_d_e_r, Jul 06 '19 at 11:49
Yes, It's working @VishrutMavani Thank you So much. – axita.savani Jul 06 '19 at 11:59 — axita.savani, Jul 06 '19 at 11:59
