在Android 5.0系统以上，调用getRunningAppProcesses() 方法来获取所有运行的进程是获取不到的，因为谷歌出于安全的考虑，所以在5.0系统以上把这个方法移除了。那么我们又该如何去获取呢？不要急，大家先看看下面一个demo的源码。不过值得注意的是，下面这种方式只适合用于5.0系统以上，以下同样也是获取不到的。以下的直接调用getRunningAppProcesses() 方法即可。
先看看效果图：
下面是MainActivity类的代码，注意里面方法里的这句 List<AndroidAppProcess> listInfo = ProcessManager.getRunningAppProcesses() ，通过它来获取。需要导入一个jar包，该包在文章末尾可以下载得到。
