Koin DI 在发布签名的 apk 时崩溃
Koin DI crashes with release signed apk
我有一个使用 Koin DI 框架的应用程序。我已经为改造、数据库、存储库等设置了所有模块，并且在调试模式下工作正常。最近我将它上传到 Play 商店，但我发现当我尝试启动该应用程序时它崩溃了。问题是它无法为我的存储库 class 创建实例，这当然有其依赖性。
这是我在 Logcat
上遇到的错误

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？？？
问题已解决。
似乎 httpLoggingInterceptor 的提供程序 return NULL 如果它是调试模式则无法创建单个。所以我将代码更改为
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()
}
现在可以了。
我有一个使用 Koin DI 框架的应用程序。我已经为改造、数据库、存储库等设置了所有模块，并且在调试模式下工作正常。最近我将它上传到 Play 商店，但我发现当我尝试启动该应用程序时它崩溃了。问题是它无法为我的存储库 class 创建实例，这当然有其依赖性。 这是我在 Logcat

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？？？
问题已解决。 似乎 httpLoggingInterceptor 的提供程序 return NULL 如果它是调试模式则无法创建单个。所以我将代码更改为
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()
}
现在可以了。
