I had the same error. I replaced the line of code, 'import android.support.v7.app.AppCompatActivity;' in line 4 or 5 with 'import androidx.appcompat.app.AppCompatActivity'. All the 6 errors i had eventually vanished including the one about "Cannot resolve v7". i'm still not totally certain that the changes are executable but it is worth a try!!
thankyou,
works wor me
This was what worked for me;
- under "activity_main.xml"
Add
android:id="@+id/quantity_text_view" to TextView 02. Ensure that the package name in "AndroidManifestxml" is the same with "MainActivity.java 3. Under MainAcitivity.java, change "import android.support.v7.app.AppCompatActivity;" to "import android.appcompat.app.AppCompatActivity;"
thanksss, works
