ViewCompat$OnUnhandledKeyEventListener on setContentView

Question

the error is triggered by the command:

setContentView(R.layout.activity_item_list);

this code was generated by android studio , when creating a new android project using the "master/slave flow"

it seems the layout was rendered but still the errors appear

as mentioned, the code is generated automatically by Android Studio 3.2.1 and selecting "Master/Detail Flow" type of Activity

@JawadMalik I doubt the file has an issue. it is autogenerated by Android Studio. I attached the code. it references an "include layout="@layout/item_list" which couldn't be pasted, but the file is very basic recyclerView, which points to another Card_View. all are part of the "Master/Detail flow" template of android studio — Dror, Nov 05 '18 at 21:00
it looks like this but sometimes there comes an issue which Android Studio also don't notify — Jawad Malik, Nov 07 '18 at 16:21
@SinoKD I used the code below. also there's a reference that might be relevant as well - https://developer.android.com/studio/build/multidex — Dror, Dec 22 '18 at 21:45

I stumbled on a github snippet that does the trick

you should paste the following to the bottom of your project's - build.gradle

// This is to fix the errors : java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
configurations.all {
    resolutionStrategy.eachDependency { details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "26.+"
            }
        }
    }
}

i ended up using the suggestion in the URL below (instead of 1) -

developer.android.com/studio/build/multidex

@Bobert try bullet 2 instead – Dror Feb 07 '19 at 18:10

For Androidx replace "com.android.support" by "androidx" – FireZenk Feb 14 '19 at 15:24
@Bobert Read the answer [here](https://stackoverflow.com/a/42957234/1770778). In the comment it says just to remove `DependencyResolveDetails` coz the type declaration is not needed. Worked for me. – ffonz Apr 10 '19 at 17:10
@Dror What do these lines do? I'm affraid to write this without understanding it. – JarsOfJam-Scheduler Jul 08 '19 at 20:06

@JarsOfJam-Scheduler forces all your dependancies to use the same support library version – Luke Brandon Farrell Jul 15 '19 at 12:59
What suggestion from that URL did you use? – AlexVPerl Aug 22 '19 at 03:56
@AlexVPerl see under the title "Configure your app for multidex", but it's irrelevant if you use minSdkVersion is set to 21 or higher – Dror Aug 22 '19 at 05:44
@Dior thanks. I tried both 1 & 2 and both resolve the warning. I'm a bit puzzled though as to why #1 works. #2 makes sense because of dex'ing, a dependency probably was not in the initial dex file used for app startup. But #1 sets version=26 for all support libs besides multidex lib - have you been able to find out why #1 works? – AlexVPerl Aug 23 '19 at 02:15
@AlexVPerl don't know why, i'm afraid. i didn't have the time to dig deeper – Dror Aug 24 '19 at 09:19
