My Android phone is 422, but the android Development SDK on the PC is 44, so that the program can run on my mobile phone?

It doesn't matter if you don't need content above 4.2.2.
You can modify
<Uses-sdk
Android: minSdkVersion = "17"
Android: targetSdkVersion = "19"/>

My mobile phone is Android 43, and I want to develop mobile phone software 43. After installing the SDK of the following versions, I found that only Android 422 is supported. Can I develop Android 43?

Android 4.3 is compatible with all low-version software and games.
