获取当前进程号和当前进程名

                    int pid = Process.myPid();//import android.os.Process不然会报错！
                    String processName = "";
                    ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);

                    List<ActivityManager.RunningAppProcessInfo> list = activityManager.getRunningAppProcesses();
                    for (ActivityManager.RunningAppProcessInfo runningAppProcessInfo : list){
                        if (runningAppProcessInfo.pid == pid){
                            processName = runningAppProcessInfo.processName;
                        }
                    }
                    Log.i(TAG,"当前进程号:" + pid);
                    Log.i(TAG,"当前进程名称:" + processName);
