如果单独运行，Android应用程序不会在真实设备上运行，但如果连接到系统（调试模式或运行模式），则会在模拟器和设备上运行
我真的很无助，为什么我的应用程序会这样运行，以及如何找出到底出了什么问题 目标：-在用户登录后在后台运行如果单独运行，Android应用程序不会在真实设备上运行，但如果连接到系统（调试模式或运行模式），则会在模拟器和设备上运行,android,service,handler,runnable,Android,Service,Handler,Runnable,我真的很无助，为什么我的应用程序会这样运行，以及如何找出到底出了什么问题 目标：-在用户登录后在后台运行服务（实际完成登录活动并启动服务），然后根据服务中的某些条件生成不同的活动 问题：-如果我在调试模式或运行模式下在emulator上运行此应用程序，那么它工作正常 如果通过连接电缆在电话上使用调试模式运行它，它会再次正常工作，当我断开电缆并将其从电话上启动时会出现问题，它会跳过所有条件，不会生成活动，我可以看到服务正在运行 测试：-我已经在所有可能的模拟器上测试了它，没有任何失败。在设备上，我
服务登录活动服务服务2.3.6姜饼和4.0.4 IC上测试了它，但在两款手机上都失败了
我使用的是：-

注释
- runnable在1分钟后运行
- 这个类中有两个Runnable，它们都根据条件打开不同的活动
- 服务启动timertask以执行所有必需的操作
只是想知道，你怎么知道它没有运行？我可以在“设置”->“应用”->“运行”中看到服务正在运行。然后你应该添加一些日志信息，并使用设备上的logcat进行检查。如果不检查服务的位置，很难知道为什么不运行。这就是问题所在，为了检查logcat，我必须通过数据电缆将设备连接到我的系统。我也试过，然后它的工作方式应该是这样的。你可以有终端模拟器应用程序的logcat，或playstore的logcat应用程序
