Cleanup Android project (Minor refactorings, etc.) (#1244)
* (Android) Get rid of double bangs by using Kotlin view binding Instead of holding a nullable reference to the WebView, we are now accessing the WebView using the view binding utility of Kotlin's Android Extensions. Further reading: https://kotlinlang.org/docs/tutorials/android-plugin.html * (Android) Enable WebView debugging in debug builds This enables debugging the app's WebView using Chrome's DevTools. https://developers.google.com/web/tools/chrome-devtools/remote-debugging/webviews * (Android) Make MainActivity.kt adhere to common Kotlin conventions * (Android) Update dependencies and improve formatting of Gradle files This updates the Kotlin plugin to 1.3.21 and the Gradle plugin to 3.3.2 * (Android) Remove unnecessary ConstraintLayout container Layout files should generally have as few nested layers as possible, because every layer affects the performance. * (Android) Use JSONObject class to construct a JSON string It is way safer to construct a JSON string using classes that are meant for doing that, instead of concatenating raw strings. * (Android) Suppress JavaScript lint warning * (Android) Use Kotlin string templates instead of concatenating strings * (Android) Add missing SuppressLint import
