Symbol class not found ActionBarActivity (Android Recycle View)… here is a solution to the problem.
Symbol class not found ActionBarActivity (Android Recycle View)
I’m having some issues building gradle: I don’t understand what the problem is, I read a lot about that but I can’t find a solution:
I’ve already: downloaded the Repository
, put in dependencies and the latest SDK version
.
I tried creating a CardView
in HomeActivity.xml
. I also have MyViewHolder.java
, PageAdapter
.java and ‘MyObject.java so: I need some help
If you want other files, I’ve made 3 TabLayout. The code is in MainActivity.java.

Solution
According to documentation ActionBarActivity has been deprecated and removed from the support library in favor of extending your activity: from AppCompatActivity
import android.support.v7.app.AppCompatActivity;
public class YourActivity extends AppCompatActivity
Application/build.gradle
android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
defaultConfig {
applicationId 'your_app_id'
minSdkVersion 16
targetSdkVersion 27
versionCode 1
versionName "1.0"
}
}
dependencies {
implementation 'com.android.support:appcompat-v7:27.1.0'
}
