error: cannot find symbol import android.support.v7.app.ActionBarActivity;

After having removed the android:allowBackup="false" line from my AndroidManifest.xml file, which prevented me to compile this project, I'm now facing the following compilation issue :

> Task :react-native-android-scanner:compileDebugJavaWithJavac FAILED
/Users/zedtux/Developments/companion/node_modules/react-native-android-scanner/android/src/main/java/com/reactlibrary/RNReactNativeAndroidScannerModule.java:11: error: cannot find symbol

Can you share your code?

Usually, I am getting
Execution failed for task ':react-native-android-scanner:compileDebugJavaWithJavac
when there is not enough free RAM memory. Try rebuilding with closing most of your browser's tabs or even the browser.
