Quick start for developers could be updated

[benryder1988]

I just did a clean install of Android Studio, and encountered the following three issues that had to be resolved before the app would compile and launch:

1. Warning messages:
   [XmlResourcesTransformer] No mapping for: android/support/FILE_PROVIDER_PATHS
   Failed to find Build Tools revision 29.0.2

Steps to fix were:

• Open Settings > Appearance & Behaviour > System Settings > Android SDK > SDK Tools
• Click on Show Package Details
• Go to Android SDK Build Tools, select version 29.0.2 and click apply, then finish

2. Warning message:
   Failed to find Platform SDK with path: platforms;android-28

Steps to fix were:

• Open Settings > Appearance & Behaviour > System Settings > Android SDK > SDK Platforms
• Click on Show Package Details
• Go to Android 9.0 (Pie), select Android SDK Platform 28 and click apply, then finish

3. Warning message:
   Missing NDK version 21.0.6113669

Steps to fix were:

• Open Settings > Appearance & Behaviour > System Settings > Android SDK > SDK Tools
• Click on Show Package Details
• Go to NDK (Side by side), select 21.0.6113669 and click apply, then finish

These three steps could be combined into the following instructions for the quick start documentation:

• Open Settings > Appearance & Behaviour > System Settings > Android SDK
• Click on Show Package Details
• Go to SDK Tools > Android SDK Build Tools, and select version 29.0.2
• Go to SDK Tools > NDK (Side by side), and select 21.0.6113669
• Go to SDK Platforms > Android 9.0 (Pie), and select Android SDK Platform 28
• Click apply, then finish

Hi @benryder1988, thanks for raising this issue - would you be able to create a PR against this repo that I can review?

Hi, I also faced similar issues while setting up, I followed steps in here. But I am still facing an issue when I run gradlew :app:installBetaDebug:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:kaptBetaDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
   > java.lang.reflect.InvocationTargetException (no error message)

Not sure what the issue is, but I am having jdk 11 in android studio.
