Determining Whether a Given Application Is Running
Published? true
FormatLanguage: WikiFormat
Problem:
How do i know if mine or some other app is running?
Solution:
The system activity manager maintains a list of all active tasks. This provides the name of all running tasks and can be interrogated for various system specific information
Discussion:
This method takes the name of an application and returns true if the ActivityManager thinks it is currently running.
import android.app.ActivityManager;
import android.app.ActivityManager.RunningAppProcessInfo;
public boolean isAppRunning (String aApplicationPackageName)
{
ActivityManager activityManager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
if (activityManager == null)
{
return false; // should report: can't get Activity Manager
}
List<RunningAppProcessInfo> procInfos =
activityManager.getRunningAppProcesses();
for(int idx = 0; idx < procInfos.size(); idx++)
{
if(procInfos.get(i).processName.equals(aApplicationPackageName))
{
return true;
}
}
return false;
}
