AndroidProcesses

A small library to get the current running processes on Android

Why would I need this?

Android 5.0+ killed getRunningTasks(int) and getRunningAppProcesses(). Both of those methods are now deprecated and only return your application process. You can get a list of running apps using UsageStatsManager, however, this requires your users to grant your application a special permission in Settings. It has been reported that some OEMs have removed this preference.

This small library can get a list of running apps and does not require any permissions.

Usage

Get a list of running apps:

List<AndroidAppProcess> processes = ProcessManager.getRunningAppProcesses();

Get some information about a process:

AndroidAppProcess process = processes.get(location);
String processName = process.name;

Stat stat = process.stat();
int pid = stat.getPid();
int parentProcessId = stat.ppid();
long startTime = stat.stime();
int policy = stat.policy();
char state = stat.state();

Statm statm = process.statm();
long totalSizeOfProcess = statm.getSize();
long residentSetSize = statm.getResidentSetSize();

PackageInfo packageInfo = process.getPackageInfo(context, 0);
String appName = packageInfo.applicationInfo.loadLabel(pm).toString();

Check if your app is in the foreground:

if (ProcessManager.isMyProcessInTheForeground()) {
  // do stuff
}

Get a list of application processes that are running on the device:

List<ActivityManager.RunningAppProcessInfo> processes = ProcessManager.getRunningAppProcessInfo(ctx);

Limitations

System apps may not be visible because they have a higher SELinux context than third party apps.

Some information that was available through ActivityManager#getRunningAppProcesses() is not available using this library (pkgList, lru, importance, etc.).
