我有一个Android应用程序，它指定了两个AIDL文件和一个服务。这个服务应该从另一个应用程序调用AIDL上定义的方法。我已经按照Android Documentation on AIDL实现了AIDL文件和服务（见下面的代码）。
然后，我创建了一个非常简单的客户端应用（如下所示）来绑定到服务并调用AIDL文件中定义的方法。然而，bindService总是返回false，并指出找不到Intent。以下是我尝试在客户端正确引用Intent的一些事情：

Intent intent = new Intent("a.b.c.service");
intent.setPackage("a.b.c");

---

Intent intent = new Intent("service");
intent.setPackage("a.b.c");

---

Intent intent = new Intent();
intent.setClassName("a.b.c", "a.b.c.services.MyService");

---

Intent intent = new Intent();
intent.setClassName("a.b.c.services", "a.b.c.services.MyService");

---

Intent intent = new Intent();
intent.setClassName("a.b.c", ".services.MyService");

---

Intent intent = new Intent();
intent.setAction("service");
intent.setPackage("a.b.c");
intent.setClassName("a.b.c", ".services.MyService");

---

Intent intent = new Intent();
intent.setAction("service");
intent.setClassName("a.b.c", ".services.MyService");

如果我从服务所在的同一应用程序尝试，我可以使用以下命令，它将正常工作：

Intent intent = new Intent(this, MyService.class);

但由于这是一个远程服务，我无法从客户端应用程序访问MyService类，因此无法找到任何使其工作的方法。
我想知道通过很多StackOverflow职位没有任何运气。
Android: Binding to a remote service如何使用AIDL远程服务来处理不同客户端的并发请求？Android Bind Service returns false every time
在这种情况下，我应该如何说明我的意图？
