How to call a Link a Native Android Module Library in React Native-CodePudding

I've been tring to use an Android Library Module but my React Native project fails building whenever I add it as a dependancy :

build.gradle

dependencies {
    . . .
    implementation project(path: ':TestLibrary')
    . . . .
}

The Native Class :

package com.my_native_class;

public class MyNativeClass extends ReactContextBaseJavaModule {
    public MyNativeClass(ReactApplicationContext reactContext) {
        super(reactContext);
    }

    @NonNull
    @Override
    public String getName() {
        return "MyNativeClass";
    }

    @ReactMethod(isBlockingSynchronousMethod = true)
    public Integer myNativeMethod() {
        return new TestLibClass().testLibClassMethod();
    }
}

The Module Library Class I'm trying to call :

package com.testlibrary;

public class TestLibClass {
    public Integer testLibClassMethod() {
        return 123;
    }
}

How can I go about calling an Android Module Library?

Thank you all in advance.

CodePudding user response：

It's telling you the problem- your dependency requires SDK version 32, you're compiling against 31. Fix your manifest (or React Native's equivalent) to specify compileSdkVersion as 32.
