安装iap本机-iap后，iap本机应用程序无法运行

Question

我有一个其他工作的反应-本地应用程序，但需要包括在应用程序内的购买，以使它被接受在应用商店。在Googling上搜索了一小会儿之后，它看起来就像是一种本能的反应-iap几乎是唯一的选择。

第一误差

在遵循安装步骤这里之后，我在Android中得到以下错误：

e: C:_path_to_my_project_\node_modules\react-native-iap\android\src\play\java\com\dooboolab\RNIap\RNIapModule.kt：(215，37)：类型错配:推断类型是字符串？但是String被认为是

正如链接中所述，错误将抛出在RNIapModule.kt文件中，我将从下面链接一个摘录(完整的代码将我推过字符限制，但自安装以来我没有更改它)。

我从指令中撤消了所有更改，似乎唯一阻止我获得此错误的是没有在android/app/build.gradle中添加存储规范，当然，在前面提到的错误之前，也出现了错误。

二次误差

在构建部分的高处，我看到了另一个错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':react-native-iap:compilePlayDebugKotlin'.

> Compilation error. See log for more details

错误日志：An unexpected packet was received before the handshake.

RN和IAP版本

React原生版本: 0.63.4

iap本机-iap版本：^8.0.5

RNIapModule.kt代码

只是抛出错误的函数块：

...
   @ReactMethod
    fun getItemsByType(type: String?, skuArr: ReadableArray, promise: Promise) {
        ensureConnection(
            promise,
            object : EnsureConnectionCallback {
                override fun run(billingClient: BillingClient) {
                    val skuList = ArrayList<String>()
                    for (i in 0 until skuArr.size()) {
                        skuList.add(skuArr.getString(i))
                    }
...

Answer 1

skuList.add(skuArr.getString(i).orEmpty())

请尝试添加.orEmpty()
