Android studio 不支持 4.4.4 版本

Question

I have a problem with android studio SDK. I know that API 19 supports all versions 4.4+ Android 4.4 APIS , but my application cannot support android version 4.4.4 . And you can see on the image

I have already installed the API 19 , but still not working. Same is and for the android 5.0.2 version.

My Manifest file

Answer 1

Now it looks clear. Your manifest contains

<uses-feature
    android:name="android.hardware.nfc"
    android:required="true" />

Which rejects app from being installed on devices which don't have NFC.
