推荐答案

您可以使用以下方法来确定调用应用程序。

You can use the following to determine the calling application.

 String callingApp = context.getPackageManager().getNameForUid(Binder.getCallingUid());

要注意的JavaDoc getCallingUid（） 它说：

It's important to note the JavaDoc for getCallingUid() which says:

返回分配给送你正在处理当前事务的过程中，Linux的UID。此流体可以与更高级别的系统服务，以确定其身份，并检查权限。如果当前线程不是当前执行传入的事务，那么它自己的uid返回。

Return the Linux uid assigned to the process that sent you the current transaction that is being processed. This uid can be used with higher-level system services to determine its identity and check permissions. If the current thread is not currently executing an incoming transaction, then its own uid is returned.
