Android 无法绑定/连接到作为AAR库一部分创建的远程服务

我创建了一个生活在图书馆内的服务。然后，该库包含在另一个试图启动该服务的项目中。我正在使用AIDL进行交互，但是当我尝试连接到服务时，我的onConnected方法从未被命中

从日志文件中，我可以看到以下错误：

D/ActivityManager: bindService callerProcessName:com.something.services.dummyproject, calleePkgName: com.something.services.dummyproject, action: com.something.services.dummyservice.IDummyService

W/ActivityManager: Unable to start service Intent { act=com.something.services.dummyservice.IDummyService cmp=com.something.services.dummyproject/com.something.services.dummyservice.IDummyService } U=0: not found

D/ActivityManager: bindService callerProcessName:com.something.services.dummyproject, calleePkgName: com.something.services.dummyservice.service, action: null

W/ActivityManager: Unable to start service Intent { cmp=com.something.services.dummyservice.service/.DummyService } U=0: not found

DummyService.java文件如下所示：

非常感谢您对我无法连接到该服务的任何帮助

嗨。谢谢你的回复。当我尝试这样做时：Intent Intent=newintent（MainActivity.this，com.something.services.dummyservice.dummyservice）；setAction（IDummyService.class.getName（））；bindService（intent、mConnection、Context.BIND\u AUTO\u CREATE）；我在A/S“无法解析DummyService”中收到错误。因此，我认为这意味着我在库中的服务在我的项目中是不可见的？我有，但即使我明确说明了整个路径，这也会失败，这让我认为，与您编写的内容（即我调用的应该是DummyService.class）一样，我的应用程序根本看不到我库中的服务。谢谢你的建议！只是在我的应用程序（包括库）运行时尝试了这一点。我得到以下错误：“错误：未找到；未启动服务。”无。电话是：com.something.services.dummyservice.dummyservice（注意，我将dummyservice移到子文件夹服务之外以使其更简单，然后重新构建并将我的库重新添加到我的应用程序中）对不起。没有/adb shell am startservice com.something.services.dummyservice.dummyservice
