java.lang.IllegalStateException:Could not execute method for android:onClick

Question

I receive this error in crash report of just some users, but I don't understand it! The app works perfectly on almost all user devices! This is not a duplicate question, because app works always, but crashes some times!

part of my code, shows the click is not something tricky:

fun grid_btn_clicked(v: View) {
        showData(findJson(K1)!!)
    }

and this is exception:

Fatal Exception: java.lang.IllegalStateException: Could not execute method for android:onClick at androidx.appcompat.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:390) at android.view.View.performClick(View.java:5716) at android.widget.TextView.performClick(TextView.java:10926) at android.view.View$PerformClick.run(View.java:22596) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:7325) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1230) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1120)

Please put showData function body. Most probably there is a null in some cases as u use !!, maybe try wrapping it with let to get secured from crashes — P.Juni, Nov 13 '18 at 05:31
If there was problem in showData why exception raised here?! — AVEbrahimi, Nov 13 '18 at 05:31
Dont really know because there is No code for other functions but if findJson can return null then u can get null in showData and in onClick — P.Juni, Nov 13 '18 at 05:35
how have you set the click listener? If in the xml, then show the xml — Vladyslav Matviienko, Nov 13 '18 at 05:39

May b you are getting null value .Try putting your code under let and check while debugging that Are u gettingnull data from findJson(k1).

fun grid_btn_clicked(v: View) {
        findJson(k1).let{
           showData(it)
        }
    }
