I have an app published in the play store with proguard rules enable and I am receiving some error reports from Android versions 4.4 and 4.2 with this trace error
java.lang.IllegalStateException:

As there is no reference to the method that is been called or the Activity and I am not able to reproduce it, I have no idea how could I fix it. (Most of the project is in java although some classes are in kotlin)
In the proguard file I have excluded domain models and some retrofit clasess, like:
# Application classes that will be serialized/deserialized over Gson
-keep class com.example.mypackage.DataModel.** { *; }
-keep class com.example.mypackage.WS.** { *; }
Thanks in advance!
Answer
While updating the project (gradle version, appCompat -> androidX …) I was forced to correct some lint uses, and one of them was to change a custom TextView that extended TextView to AppCompatTextView.
I had forgotten that in old Android versions when you extend a custom view from AppCompatView all your xml onClick properties no longer work, and NoSuchMethodException is thrown.
