Добавлял этот код в свой MainActivity.java но ничего не работает, кнопка назад просто делает выход из приложения
@Override
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
мой MainActivity.java
package com.mobile;
import android.os.Bundle;
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
import expo.modules.splashscreen.singletons.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;
public class MainActivity extends ReactActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(null);
// SplashScreen.show(...) has to be called after super.onCreate(...)
// Below line is handled by '@expo/configure-splash-screen' command and it's discouraged to modify it manually
SplashScreen.show(this, SplashScreenImageResizeMode.CONTAIN, ReactRootView.class, false);
}
/**

@Override
protected String getMainComponentName() {
return "main";
}
@Override
protected ReactActivityDelegate createReactActivityDelegate() {

}
};
}
@Override
