I think in ViewCompat class does not have dispatchUnhandledKeyEventPre method. I am using some third party dependency so I don't know which method causing it

check you are using 1.0.0-beta01 version of appcompat library

This question already has an answer here: How do I fix a NoSuchMethodError? 27 answers I have a project that I can run correctly from within Eclipse, but running the

For me, going to the gradle.build file and making sure that all the dependencies are up-to-date (new versions) fixed this problem.

The accepted answer, while correct, shall become obsolete in the near future when newer versions of appcompat will be released since the answer is very specific to a particular time frame.

The general answer is that this happens when you are using different mixed versions of appcompat (appcompat library) in your project, they tend to be incompatible with each other more often. You must check if you are using the latest version of the appcompat library every time you update some APIs through the SDK Manager. It is rather very easy to update if you are using Android Studio.

Go to your build.gradle (Module: app) and look into the dependencies. The gradle linter will most probably already show you the error that you are using different versions of the appcompat library and whether a newer version is available or not. If you hover over those highlighted lines, it shall give you all the information you require including what version you are using and what is the latest available and whether all of the dependencies are on the same version or not. Follow the prompts, fix them and then run a gradle sync and you should be fine.

For example, I was using mixed versions of com.android.support:appcompat-v7:28.0.0-alpha3, com.android.support:design:28.0.0 and com.android.support.constraint:constraint-layout:1.1.2 while the latest were v28.0.0 and v1.1.3.

Hope this helps.

Comments
  • Maybe related to all the other issues regarding OnUnhandledKeyEventListener in ViewCompat?
  • I am using implementation 'androidx.appcompat:appcompat:1.0.0-beta2'
  • use 1.0.0-beta01 it works for me. i had the same issue as you before actually just yesterday
  • i am not using any mixed combination, i am using alpha3 version but still this happening. any suggestion ?
  • @PrakashSharma can you somehow share a screenshot of your build.gradle (module: app) file and whether Android Studio is showing any suggestions or not?
