I am a beginner Android developer. I using the 'WebView' had tried to make a Android App. However, the speed of the web is too slow. So the Internet search results found GeckoView. But homepage has been difficult for me to understand I do not know English well.
My questions:
Can I use GeckoView instead of the WebView? Is it simple?
Can I use a code library that just adds to the 'build.gradle' in Android Studio?
Is there another altenative?
Gecko view is only experimental. You can't use for production

So your only choice would be a webview. If you are great in javascript, I would recommend you to use react-native. This is how facebook is made, and you can follow extensive documents mentioned here.
