问题描述
抱歉，我知道论坛上已经存在类似的问题，但是似乎没有一个问题与我在这里遇到的问题完全相同。我刚刚完成了Android教程课程，并且构建并发布了我的第一个应用程序-我是新手，所以如果我做过一些愚蠢的事情，请原谅我！
我的应用程序可以在笔记本电脑上正常工作-在具有各种SDK版本的各种仿真器上，并且在通过USB电缆插入笔记本电脑时也可以在真实设备上运行。但是，当我将其上传到GooglePlay商店（等待3天以供审核！）时，当我将其下载到与通过USB连接的设备相同的设备上时，它不起作用。
该应用程序在打开第一页之前就崩溃了，并且我可以得到的唯一错误信息是GooglePlay提供的错误信息-包括在下面。问题似乎出在我的解析初始化中，但我不知道是什么或为什么？任何帮助将不胜感激！

解决方法
在调试中将minifyEnabled设置为true。也许minifyEnabled删除了一些不应删除的代码。由于它在仿真器上工作正常。然后在本地调试代码。
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
debug {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
