Question

当我在模拟器中运行并安装我的应用程序时，它工作正常。然后我关闭应用程序并开始下一次它开始崩溃。我试图阅读不同的问题，但对我没有帮助

程序读取epub / fb2文件并在屏幕上显示

很抱歉链接，但我无法正确格式化代码，问题是错误

堆栈跟踪

无法找到显式活动类{net.textreaderfb2epub.textReader / net.textreaderfb2epub.textReader.TextReader};你有没有在AndroidManifest.xml中声明这个活动？

我愿意打赌你没有将#!groovy pipeline { agent any // Set log rotation, timeout and timestamps in the console options { buildDiscarder(logRotator(numToKeepStr:'10')) timeout(time: 5, unit: 'MINUTES') } stages { stage('Initialize') { steps { sh ''' java -version node --version npm --version ''' } } } }活动添加到TextReader。尝试在AndroidManifest.xml标记中添加类似内容：

<application>

为什么我的应用程序在首次良好发布后会崩溃？
