如何在异常处理程序中映射 proguard？

如何解决如何在异常处理程序中映射 proguard？

我实现了一个 Exeption Handler 来捕获应用程序上的所有异常。

class ExceptionHandler : Thread.UncaughtExceptionHandler {
    private val LINE_SEParaTOR = "\n"
    override fun uncaughtException(thread: Thread,exception: Throwable) {
        val stackTrace = StringWriter()
        exception.printstacktrace(PrintWriter(stackTrace))
        val errorReport = StringBuilder()
        errorReport.append("************ CAUSE OF ERROR ************\n\n")
        errorReport.append(stackTrace.toString())
        // Todo: Report log
    }
}

我收到了一份 NPE 报告，如下所示。但我不知道它是什么，因为它被混淆了

java.lang.NullPointerException
    at l.d(java-style lambda group:2)
    at androidx.lifecycle.LiveData.b(LiveData.java:6)
    at androidx.lifecycle.LiveData.c(LiveData.java:8)
    at x.r.x.j(mutablelivedata.java:4)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

Exampleviewmodel 报错的那一行是这样的：

fun callAPI(requestBody: MyRequestBody): Job = viewmodelScope.launch {
    try {
        val response = repository.fetchAPI(requestBody)

        if (response.isSuccessful) {
                _responseBody.value = response.body()
        } else {
            val msg = "callAPI() ${response.code()}: ${response.message()} ${response.errorBody()!!.string()}"
            when {
                response.code() >= 500 -> {
                    _toastMsg.value = msg
                }
            }
        }
    } catch (e: java.lang.Exception) {
        _toastMsg.value = "${e.toString()}"
    }
}

该函数使用了一个如下所示的参数：

@Parcelize
@Keep
data class MyRequestBody(
        val aData: String,val bData: String,val cData: String,val dData: String,val eData: String,val fData: String,val gData: Int,val hData: String?,val iData: String?,val jData: String?,val kData: String?
):Parcelable{
    override fun toString(): String {
        return "${aData},${bData},${cData}..."
    }
}

如何映射数据以便我可以看到它们的原始名称？哪个部分会导致 NPE？ （我猜响应 perce 是空的？） 我不知道如何在应用程序以及 LiveData、mutablelivedata 上进行映射。
