AndroidProcesses

A small Android library to get the current running processes

What is this library for?

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

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.

Android Nougat

Google has significantly restricted access to /proc in Android Nougat. This library will not work on Android 7.0. Please star this issue. To get a list of running processes on Android Nougat you will need to use UsageStatsManager or have root access. Really Google?

Usage

Get a list of running apps:

List<AndroidAppProcess> processes = AndroidProcesses.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 (AndroidProcesses.isMyProcessInTheForeground()) {
  // do stuff
}

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

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

Limitations

System apps will not be included on some Android versions because they have a higher SELinux context.
This is not a full replacement of getRunningAppProcesses(). The library does not provide a processes' pkgList, lru, or importance.
This is currently not working on the N developer preview.
