我在eclipse中创建了一个应用程序，并且每当我想打开它时它都会继续崩溃。应用程序应该能够在收到特定措辞的文本消息时关闭手机。它确实需要root权限。另外我运行它的方式是按下eclipse上的运行按钮，它表明我没有编码错误，所以你可以看到我很丢失。
这是日志文件：

答案 0 :(得分：2)
java.lang.ClassNotFoundException: Didn't find class "com.rabazid.abzsmspoweroff.SmsLoggerActivity"
您缺少我认为的类定义。
答案 1 :(得分：1)
这很可能是构建问题
如果使用构建计算机构建此代码，则可能是在构建过程中排除了代码。
如果您没有使用构建机器..那么您可以尝试的一件事是删除bin / gen目录并重新生成所有文件。如果你查看bin目录并按照com.rabazid.abzsmspoweroff.SmsLoggerActivity路径，那么你将看到它是否包含在你的apk中。 bin目录中的所有内容都是应用于最终二进制文件的内容。另外要检查的是你的程序规则。
如果一切顺利，那么你应该在各自的路径中看到com.rabazid.abzsmspoweroff.SmsLoggerActivity。
