This solution work on me.

1- Go to "sdk\extras\android\m2repository\com\android\support\recyclerview-v7*22.1.1*" ( 22.1.1 latest version for now. )

2- Open recyclerview-v7-22.1.1.aar file with Winrar.

3- There is a jar file named classes.jar. Copy that to your project libs folder.

4- Right click classes.jar, add to build path.

Thats it.

Answer 4

Disable the androidx from gradle.properties file using true --> false

android.useAndroidX=false

android.enableJetifier=false

then change these lines to api v28 in build.gradle(Module:app)

compileSdkVersion 28

targetSdkVersion 28

then add these line in to build.gradle(Module:app)

`implementation 'com.android.support:appcompat-v7:28.0.0'`
`implementation 'com.android.support:recyclerview-v7:28.0.0'`
`implementation 'com.android.support:cardview-v7:28.0.0'`
`implementation 'com.android.support:design:28.0.0'`

Then sync the project

Answer 5

I guess I can answer my own question.

Go to File -> Import -> Existing Android code into workspace --> Browse (Go to sdk/extras/android/support/v7/cardview) --> Click ok --> Click Finish

Your project explorer will now show cardview as a project.

Right click on cardview project --> Properties --> Android(Left Pane) --> Enable isLibrary (tick the checkbox) --> Apply --> ok

Now Right click on your project --> Properties --> Android(Left pane) --> Add (under library) --> cardview --> apply --> ok

Now right click on your project again --> build path --> configure build path --> Under projects tab, add cardview

You are done.

Answer 6

If you're using VISUAL STUDIO and get this error, try restarting VS and then Rebuild Solution. That worked for me. Hopefully this saves someone some time.
