Flutter android 簽名發布后嘗試調試時應用程序崩潰

Question

我是 flutter 的新手，我正在構建一個 flutter 應用程序作為學校項目的一部分。 我和我的團隊正在構建 ios、android 和 web 應用程序版本，我的任務是生成和簽署我的應用程序包以在 google play 中發布。 我能夠成功簽署捆綁包並上傳項目。 我無法在模擬器上測試發布版本，但這是另一個可能相關的問題。

關於這一點，我現在在調試我的應用程序時遇到了問題。 在重命名和配置構建類型之前沒有問題，我只是使用默認應用程序 ID 並在 VScode 中運行調試器。 我的應用程序似乎構建成功（我認為是因為我沒有收到錯誤），但它沒有正確安裝在模擬器上。 我收到一個關於仿真的彈出通知，不幸的是應用程序不斷關閉。 在捕獲日志中，我看到“等待天文台端口可用......”。

我已經重置了模擬器，flutter 清理並重建。 我曾嘗試在 android 工作室（調試）中運行/清理/構建，但無濟於事。

這是捕獲日志。 我沒有將它們全部包括在內，因為看起來應用程序正在正確構建。

這是我的應用程序級別 build.gradle。 請注意我的構建類型。 我不確定這些配置是否正確。 我關注了 https://flutter.dev/docs/deployment/android但他們對如何設置構建類型的解釋有限。

這是我的 android 清單。 我想知道 MainActivy 是否是問題所在。 我不太確定該文件在哪里/究竟是什么，並且在捕獲日志的末尾有一個在啟動 Intent 時對其的引用。 ``

Answer 1

我已經解決了這個問題。 當我更改應用程序名稱/ID 時，我不小心更改了 MainActivity.java class 名稱。 我將 Sensational Science 中的 class 名稱更改為 MainActivity。

package com.sensationalscience.sensational_science

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}
