I updated my build and target version to 28 (Pie) and replaced the relevant dependencies. Now my project says Symbol not found on AppCompatActivity
. I have tried to
But the result is the same. Moreover when I try Ctrl+Space after extends keyword in activity class there is no "AppCompatActivity
suggestion. I tried to investigate if its present in libraries
folder, it's present there.
Now, what should I do to make it work? If there is any variation/alternative with androidx
libs please let me know. Here is my complete build.gradle
file
apply plugin: 'com.android.application'

Some other posts suggest adding the below two parameters in Manifest
file
android:appComponentFactory="anystrings be placeholder"
tools:replace="android:appComponentFactory"
But with these two lines project sync with multiple error and Android Studio says
Compilation failed; see the compiler error output for details.
If I have to add more detail to the question please let me know.
you should replace the target class.
eg.
import android.support.v7.app.AppCompatActivity;
replace to :
import androidx.appcompat.app.AppCompatActivity;
