Error with running App with react-native-ble on Android in debug mode

Hi,

I'm attempting to run App on react-native-ble on my Adroid, but I recieve this error. How would I fix it?

AndroidManifest.xml:9:5-11:41 Error:
uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library

Suggestion: use tools:overrideLibrary="com.geniem.rnble" to force usage

1. Does this only happen when you run in debug mode?
2. Assuming you aren't using an emulator (which wont work), it sounds like your phone's OS is outdated. Have you tried updating it?

Yes, I'm not using the debug mode. I believe the reason is caused because my phone OS is outdated.

So I purchased Android this tablet.

The OS it's using is Android 6.0.

I also downgraded to React Native v0.38.0. After linking react-native-ble, I get the same error:

AndroidManifest.xml:9:5-11:41 Error:
uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library

I can't image that the OS is out of date.
