如何在 React Native 中調用原生 Android 模塊庫的鏈接

Question

我一直在嘗試使用Android 庫模塊，但是每當我將其添加為依賴項時，我的React Native項目都無法構建：

build.gradle

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

本機 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();
    }
}  

我試圖調用的模塊庫 Class ：

package com.testlibrary;

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

我如何 go 關於調用 Android 模塊庫？

謝謝大家。

以下是每當我調用npx react-native run-android時的 StackTrace ：

它告訴您問題所在 - 您的依賴項需要 SDK 版本 32，您正在針對 31 進行編譯。修復您的清單（或 React Native 的等效項）以將 compileSdkVersion 指定為 32。
