Koin DI与发布签名的apk崩溃

Question

我有一个使用Koin-DI框架的应用程序。我已经为改装、数据库、存储库等设置了所有模块，在调试模式下运行良好。最近我把它上传到Play Store上，但当我试图启动应用程序时，我发现它崩溃了。问题是它不能为我的Repository类创建一个实例，当然这个类有它的依赖项。这是我在Logcat 上得到的错误

既然Koin设置正确(因为它在调试模式下工作(，为什么会发生这种情况？？？

Answer 1

问题解决了。httpLoggingInterceptor的提供程序(如果是调试模式则返回NULL(似乎无法创建单个。所以我把代码改成

single<Interceptor> {
val httpLoggingInterceptor = HttpLoggingInterceptor()
httpLoggingInterceptor.level = HttpLoggingInterceptor.Level.BODY
return@single httpLoggingInterceptor
}
.....
single {
val httpClientBuilder = OkHttpClient().newBuilder().apply {
connectTimeout(60, TimeUnit.SECONDS)
readTimeout(60, TimeUnit.SECONDS)
writeTimeout(60, TimeUnit.SECONDS)
addInterceptor(get<HeaderInterceptor>())
if (!BuildConfig.DEBUG) addInterceptor(get<Interceptor>())
}
return@single httpClientBuilder.build()
}

现在它起作用了。
