AIDL消费者获取Java包名

问题描述

我揭露过机制的一些API。客户端需要绑定到AIDL和同步调用方法。有没有一种方法，我可以检索客户端的Java包名？

I am exposing some API through AIDL mechanism. Clients need to bind to the AIDL and call methods synchronously. Is there a way I can retrieve the client's Java package name?

例如，如果我公开的方法布尔isFooAvailable（）作为AIDL API，从isFooAvalable的实现中，我能确定该应用程序的Java包名称绑定到AIDL服务？

For example, if I expose a method boolean isFooAvailable() as AIDL API, from within the implementation of isFooAvalable, can I determine the Java package name of the app that binds to the AIDL service?

推荐答案

是的，你可以在执行中找出包名称如下：

Yes, you can find out the package name from within the implementation as follows :

IAidl.Stub mBinder = new IAidl.Stub() {

    @Override
    public boolean isFooAvailable() throws RemoteException {

       String pkgName = "";
        int pid = Binder.getCallingPid();

        ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> processes = am.getRunningAppProcesses();

        for (ActivityManager.RunningAppProcessInfo proc : processes) {

            if (proc.pid == pid) {

                pkgName = proc.processName;
            }
        }
       // package name of calling application package
       Log.e("Package Name", pkgName);
       return false;
    }
}

通过PID查找包的名称是最好的办法相比，UID。

Finding package name through PID is the best approach compared to UID.
