The new version of React Native has issued support for RTL devices:
https://facebook.github.io/react-native/blog/2016/08/19/right-to-left-support-for-react-native-apps.html
I managed to fix this by adding to MainApplication.java
:
import com.facebook.react.modules.i18nmanager.I18nUtil;
public class MainApplication extends Application implements ReactApplication {
@Override
public void onCreate() {
super.onCreate();
// FORCE LTR
I18nUtil sharedI18nUtilInstance = I18nUtil.getInstance();
sharedI18nUtilInstance.allowRTL(getApplicationContext(), false);
....
}
}
