Failed to build react native app after linking with ble-plx - react-native

Question

react-native run-android failed after linking with react-native-ble-plx
Task :react-native-ble-plx:compileDebugJavaWithJavac FAILED
This is a newly created app with react-native init, didn't change anything except the min sdk.
Already tried to clean project, set min sdk to 18, tried to build with android studio to get more specific error but still can't understand where is the problem coming from.
The Error i get:
Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.

Answer 1

This issue is similar to this issue.
As mentioned in #Kreator answer it is related to some packages that are not converted to AndroidX.
To fix this issue you can use jetifier.
I have the same issue mentioned in the question and these steps solved it and application run again.
First, use Android Studio's refactoring tool to convert your app re: the Android developer docs
npm install --save-dev jetifier
npx jetify
npx react-native run-android (your app should correctly compile and work)
Call npx jetify run in the postinstall target of your package.json (Any time your dependencies update you have to jetify again)

Answer 2

Problem was that i was using Android Studio Preview, and with that AndroidX and more unsupported packages.

BUILD FAILED in 54s
error Failed to install the app. Make sure you have the Android
development environment set up:

Solution
this was my build.gradle project:
buildscript {
ext {
buildToolsVersion = "30.0.2"
minSdkVersion = 21
compileSdkVersion = 31
targetSdkVersion = 31
ndkVersion = "21.4.7075529"
kotlin_version = "1.6.0" // Update this to your version
}
repositories {
google()
mavenCentral()
}
...
}
I changed the some version to as following:
compileSdkVersion = 29
targetSdkVersion = 29
And now the Build is successful!
