Answer 1

I followed the answer of Bevilaqua

Then, a dialog poped to make a Gradle Plugin Update : Android Gradle Plugin Update Required

Of course, it failed : enter image description here

So, to fix it, I manually installed a recent version of Gradle from enter link description here in my .gradle folder (in Windows C:\Users\...\.gradle\wrapper\dists\)

And I got another problem because a these line in styles.xml : <style name="Widget.Shrine.TextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.OutlineBox"> where I replaced OutlineBox by OutlinedBox : <style name="Widget.Shrine.TextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox"> (Source)

Now, everything is functional.

Answer 2

you're trying to find a SDK that corresponds to the version "android-p". Have a look at your build.gradle file: android { compileSDKVersion 'android-p' .......... }

change it to android { compileSDKVersion 28 .......... } note that the version 28 is just one example, you could be using any version.

that should do the job for you.
