Cannot get all running Android processes - android

I want to get all running processes in my phone. I have tried this code
ActivityManager am = (ActivityManager)
getBaseContext().getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> pids = am.getRunningAppProcesses();
But this code returns only my process.


ActivityManager am = (ActivityManager)this.getSystemService( ACTIVITY_SERVICE );
List<RunningAppProcessInfo> listProcess = am.getRunningAppProcesses();
for(RunningAppProcessInfo runningProInfo:listProcess){
Log.i("Running Processes", ":"+runningProInfo.processName);
}
Working code.
Hope this helps..

Get Running Applications on a non rooted Android

I've seen many posts about how to get the running processes on Android, but things changed with Lolipop. Now the list is trunked for non rooted devices.
Every post was about to do this kind of code:
ActivityManager am = (ActivityManager) mContext
.getSystemService(Activity.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfo = this.getActivityManager().getRunningAppProcesses();
List<ActivityManager.RunningTaskInfo> taskInfo = this.getActivityManager().getRunningTasks(Integer.MAX_VALUE);
I tried it and the only thing that is retrieved is your current application.
#Stan was talking about developping an accessibility service here in this post: How to check current running applications in Android?
I checked the API, and what I saw is that you could be informed of application launch with an accessibility service, but not if it's still running afterward. So I don't think this is the good way to do it.
Does anyone have an idea about how to do it?

In Android Lolipop your code will not work as from Android L onward getRunningTask will not work. You have to use getAppRunningProcess.
Here is the code:-
public static String[] getActivePackagesCompat() {
final List<ActivityManager.RunningTaskInfo> taskInfo = mActivityManager.getRunningTasks(1);
final ComponentName componentName = taskInfo.get(0).topActivity;
final String[] activePackages = new String[1];
activePackages[0] = componentName.getPackageName();
return activePackages;
}
public static String[] getActivePackages() {
final Set<String> activePackages = new HashSet<String>();
final List<ActivityManager.RunningAppProcessInfo> processInfos = mActivityManager.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo processInfo : processInfos) {
if (processInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
activePackages.addAll(Arrays.asList(processInfo.pkgList));
}
}
return activePackages.toArray(new String[activePackages.size()]);
}

I want to create an application that shows all the applications that were launched

Time and Name of application opened
final PackageManager pm = getPackageManager();
packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
for(ApplicationInfo packageInfo : packages )
{
String name=packageInfo.getClass().getName();
Toast.makeText(ListActivity.this, ""+ name, 0).show();
}

Try this to get the list of running apps.
ActivityManager activity_manager = (ActivityManager) context.getSystemService(Activity.ACTIVITY_SERVICE);
Use getRunningTasks() method from ActivityManager.
final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final List<RunningTaskInfo> recentTasks = activityManager.getRunningTasks(Integer.MAX_VALUE);
for (int i = 0; i < recentTasks.size(); i++)
{
Log.d("Executed app", "Application executed : " +recentTasks.get(i).baseActivity.toShortString()+ "\t\t ID: "+recentTasks.get(i).id+"");
}
Add this permission in the manifest file.
<uses-permission android:name="android.permission.GET_TASKS" ></uses-permission>

How to get PID from package name?

I need create a function but I don't know how to get the PID of the app.
// here return -1 but I need PID to kill process
Integer PID1= android.os.Process.getUidForName("com.android.email");
android.os.Process.killProcess(PID1);

try
restartPackage code
ActivityManager aM = (ActivityManager);
getApplicationContext().getSystemService(getApplicationContext().ACTIVITY_SERVICE);
aM.restartPackage("com.android.email");
Kill BackGround Process Code
ActivityManager aM = (ActivityManager)
getApplicationContext().getSystemService(Catalogue.content_holder.getApplicationContext().ACTIVITY_SERVICE);
aM.killBackgroundProcesses("com.android.email");
Here is code which fetches all running Application and check wether email app is already running or not , if it is running then kill that process
ActivityManager manager = (ActivityManager) getApplicationContext.getSystemService(getApplicationContext.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> activityes = ((ActivityManager)manager).getRunningAppProcesses();
for (int iCnt = 0; iCnt < activityes.size(); iCnt++){
System.out.println("APP: "+iCnt +" "+ activityes.get(iCnt).processName);
if (activityes.get(iCnt).processName.contains("com.android.email")){
android.os.Process.sendSignal(activityes.get(iCnt).pid, android.os.Process.SIGNAL_KILL);
android.os.Process.killProcess(activityes.get(i).pid);
//manager.killBackgroundProcesses("com.android.email");
//manager.restartPackage("com.android.email");
System.out.println("Inside if");
}
}

Detect whether process is system process or not

I am using this method to get running processes
private void getRunningProcess() {
{PackageManager pm=getActivity().getPackageManager();
final ActivityManager manager = (ActivityManager)getActivity().getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> runningProcesses = manager.getRunningAppProcesses();
if (runningProcesses != null && runningProcesses.size() > 0) {
setListAdapter(new ListAdapter(getActivity(), runningProcesses));
}
}
I am getting all processes but I want to show only non-system processes.
Any help will be appreciated.

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<RunningAppProcessInfo> run = am.getRunningAppProcesses();
try it!

Monitoring app launches on android

I need to create an app that is able to check when other apps are opened or closed ("on resume" or "on pause") on the device. I need to check the time of use of each app.
Can I do it without root access in the device?

try this code
ActivityManager activityManager = (ActivityManager) this.getSystemService( ACTIVITY_SERVICE );
List<RunningAppProcessInfo> procInfos = actvityManager.getRunningAppProcesses();
for(int i = 0; i < procInfos.size(); i++){
if(procInfos.get(i).processName.equals("com.android.browser")) {
Toast.makeText(getApplicationContext(), "Browser is running", Toast.LENGTH_LONG).show();
}
}
find the package name using download package name viewer
