I am trying to create my apk and enable the following flags in release build type
- minifyEnabled true
- shrinkResources true
When creating apk for release, I get the following warnings from proguard, and as a result, my build does not work (see below).
I tried to suppress the warning by adding the following to my pro pro pro pro pro
-dontwarn android.test. ** -dontwarn com.amazonaws. ** -dontwarn com.android.volley. ** -dontwarn com.fasterxml.jackson. ** -dontwarn com.viewpagerindicator. ** -dontwarn okio. ** -dontwarn org.joda.time. ** -dontwarn se.walkercrou. ** -dontwarn org.codehaus.mojo. **
After that, I was able to generate the APK, but when I try to run the APK on my mobile device, it crashed into Launch.
Then I even researched what we can add
-libraryjars '/to/jar/file.jar' , jar (s), , Gradle.
:
:app:proguardRelease

Warning: there were 63 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

Warning: there were 5 instances of library classes depending on program classes.
You must avoid such dependencies, since the program classes will
be processed, while the library classes will remain unchanged.

Warning: there were 13 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile the code.
