I'm following this tutorial page
and i get the exact same error that they say in that page
Failed to find target with hash string 'android-P' in: D:\Development\Android\Sdk Install missing platform(s) and sync project
when i click
install missing platform(s) and sync project it shows the error as
All packages are not available for download! The following packages are not available:
- Package id platforms;android-P
I have installed almost all the SDK it asks for ANDROID - P.
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.
It looks like issue is ralated to checksums in repositories. Take a look at this answear: https://stackoverflow.com/a/50842352
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">

Now, everything is functional.
