Backwards Compatibility of Google APIS in Android - android

I am trying to import sample code with
Build target: Google APIS 1.6
minSDK: 4
I have downloaded the Android API 4 but the lowest Google APIS version I find on the SDK Manager is 8.
Eclipse creates a blank project with no classes and throws AndroidManifest.xml file missing!
Theres a few things I dont understand:
When I create a project using Google APIS only the Google APIS version is important? I forget about Android API?
Are Google APIS versions backwards compatible?

Google API SDK should be available from 1.6 and up version.
They contain the basic SDK for the version, and additional APIs such as C2DM.
Not sure what you mean with backwards compatbility. An 2.2 version SDK should be able to use 1.6. API calls.

Understanding ability to use AndroidX in old Apps

I would like to use AndroidX if I can (instead of the support library). I read that it is backwards compatible, and people have been using it with API 21. Due to some limitations with one of our vendors... our app is built to only work on Android SDK 5, API 21. When I search for AndroidX packages in the Nuget Package Manager in Visual Studio.. the Dependencies listed are MonoAndroid.Version=v9.0. Does this mean I cannot migrate to AndroidX for my project?
AndroidX can work on API 21. MonoAndroid.Version=v9.0 is not indication of the API level, this is Microsoft's version number that has nothing to do with Google SDK version numbers.
So yes, you can migrate, I have migrated one project that targets API 21.

Is it possible to support newer android sdk versions in react-native?

I was following setup guide for android in react-native documentation
and have it up and running correctly using suggested SDK v23
However there are much newer SDK versions available, I would like to set v23 as a minimum SDK version, but use latest one as my main one.
Being new to android I'm not sure on how to achieve this, what steps should I take? I can see option to edit sdk versions in some xml files and can download latest one using Android Studio.
As a side note, what are my limitations of using SDK v23? Will it not work on newer devices, do I loose out on performance etc... ?
According to some sources React Native does support up to API level 25, but there seems to be some disagreement on the issue. So according to official sources, React Native only supports Android API level 16 to level 23.
I haven't used React Native myself, but assuming versioning works the same as native development, an application with a compileSdkVersion lower than the version it is running against will run fine. The only limitations on the application would be that it would be unable to access the new features and APIs introduced by those higher SDK versions.
For example, Android 8.0 (API level 26) introduced a new Picture-in-Picture API, but the method used to enter picture-in-picture mode would not be available in code compiled against API level 23. Some new features may effect performance (usually positively), but an application compiled against API level 23 won't perform any worse on on a device running on API 26 than one running on API 23.

Android 1.6 Google API missing from SDK manager

I'm building an application for Android 1.6 that uses Google's MapActivity. However, I can't seem to find the Google API level 4 in SDK manager. I only have Google API for levels 13 and 14.
What should I do?
Thanks

Can't find android sdk 2.3.4 in SDK manager

I'm having problems finding the 2.3.4 sdk in the Android SDK Manager download list. I updated the SDK tools to r11 and my platform-tools to r5 but 2.3.4 won't show up. Is there something I'm missing?
Check out Android 2.3.4
API Level
"The Android 2.3.4 platform does not increment the API level — it uses the same API level as Android 2.3.3, API level 10.
To use APIs introduced in API level 10 in your application, you need compile the application against the Android library that is provided in the latest version of the Google APIs Add-On, which also includes the Open Accessory Library.
Depending on your needs, you might also need to add an android:minSdkVersion="10" attribute to the element in the application's manifest. If your application is designed to run only on Android 2.3.3 and higher, declaring the attribute prevents the application from being installed on earlier versions of the platform.
For more information about how to use API Level, see the API Levels document."
Google didn't release 2.3.4 into the SDK because it contains only bug-fixes. It doesn't add or change any APIs, so there is no need for an update on 2.3.3.

Android build target, duplicates, which to choose?

When creating a new android project, the build target has two choices:
Android 2.2, Android Open Source Project
AND
Google API's, Google Inc.
Both show Platform as 2.2 and API level 8
Which to choose (and why)?
The AVD with Google API's contains google Api's like GoogleMaps.
For example:
If you application uses GoogleMaps, then you will have to use an AVD with Google API's.
