Question

当我启动我的应用程序时，它会打开启动器屏幕并关闭它显示我＆＃34;不幸的是[appname]已经停止＆＃34;，它没有显示日志上的任何消息，它只发生在我的设备（Android）。一旦它显示一条消息＆＃34;目标机器就会主动拒绝它＆＃34;，就像这样...... 它发生在我开始实现推送通知后......我正在使用xam.plugin.pushnotification，firebase api以及我卸载了plugin.pushnotification，但错误仍然在这里有人见过吗？

正在搜索，我在设备日志中看到了这个错误：

（它们不是代码，但stackoverflow只允许我将其作为代码发布.lol）还有其他的东西，但是现在，它们似乎是最重要的调查......

obj中有一个文件夹（不包括在我的proj中），其名称在错误 md583ab84639d21035a23b6a55e87c99374 中提及，里面是mainapplication类...
