In Android 6.0 Marshmallow I query for the foreground app with the following code but there was a problem with incoming notifications because it shows foreground app to the app which sends notification. The problem exists only in Marshmallow (5.X works correctly).
// API 21 and above
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public static String getProcessNew(UsageStatsManager mUsageStatsManager, Context c) throws Exception {
String st = null;
try {
long endTime = System.currentTimeMillis();
long beginTime = endTime - 1000 * 10;
// We get usage stats for the last minute
List<UsageStats> stats = mUsageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, beginTime,
endTime);
// Sort the stats by the last time used
if (stats != null) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : stats) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
st = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
} catch (Exception e) {
Log.d("main", "Wxxxxexx " + e);
}
return st;
}
and then notification problem is solved using solution from this answer UsageEvents.
As solution in answer I put the code and its working to get Foreground app but it delayed by 3 seconds. My service is checking foreground app and is repeating every 500ms but whatsapp package detects after 3 seconds of starting whatsapp. this is code of UsageEvents i use from above solution.
if (BuildV >= 23) {
long endTime = System.currentTimeMillis();
long beginTime = endTime - 1000 * 10;
UsageEvents usageEvents = mUsageStatsManager.queryEvents(beginTime, endTime);
UsageEvents.Event event = new UsageEvents.Event();
while (usageEvents.hasNextEvent()) {
usageEvents.getNextEvent(event);
}
if (st.equals(event.getPackageName())
&& event.getEventType() == UsageEvents.Event.MOVE_TO_FOREGROUND) {
pack = st;
}
}

I need to know when a specific app is in the background (not foreground).
I was able to get package name of all the applications running in the background with this code:
ActivityManager activityManager = (ActivityManager) getApplicationContext().getSystemService(ACTIVITY_SERVICE);
// Process running
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager mUsageStatsManager = (UsageStatsManager)getSystemService(USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
// We get usage stats for the last 10 seconds
List<UsageStats> stats = mUsageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000*10, time);
// Sort the stats by the last time used
if(stats != null) {
SortedMap<Long,UsageStats> mySortedMap = new TreeMap<Long,UsageStats>();
for (UsageStats usageStats : stats) {
mySortedMap.put(usageStats.getLastTimeUsed(),usageStats);
Log.d("RunningAppProcessInfo","Package name : "+usageStats.getPackageName());
}
}
}
But now how do I check if the specific app is on the list or not?
Thanks
If you want to check Specific Package than check below code I have added code in below method.
ActivityManager activityManager = (ActivityManager) getApplicationContext().getSystemService(ACTIVITY_SERVICE);
// Process running
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager mUsageStatsManager = (UsageStatsManager)getSystemService(USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
// We get usage stats for the last 10 seconds
List<UsageStats> stats = mUsageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000*10, time);
// Sort the stats by the last time used
if(stats != null) {
SortedMap<Long,UsageStats> mySortedMap = new TreeMap<Long,UsageStats>();
for (UsageStats usageStats : stats) {
mySortedMap.put(usageStats.getLastTimeUsed(),usageStats);
Log.d("RunningAppProcessInfo","Package name : "+usageStats.getPackageName());
if(usageStats.getPackageName().equals("package name")) {
Log.d("Package ","Package name : Success");
}
}
}
}
I'm working an app called 'Prevent Uninstall', in this app user creates 4 digit pin and I'm going to save this pin in sharedpreferences. My requirement is when user clicks uninstall button of any application a popup or window should be displayed to confirm the pin which is already created in my application. So is it possible?, if possible please help me, i got stuck at this point.
hello guys finally i have found a solution below..
first get the current activity on foreground
public boolean isConcernedAppIsInForeground() {
ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> task = manager.getRunningTasks(5);
if (Build.VERSION.SDK_INT <= 20) {
if (task.size() > 0) {
ComponentName componentInfo = task.get(0).topActivity;
for (int i = 0; pakageName != null && i < pakageName.size(); i++) {
if (componentInfo.getPackageName().equals("com.google.android.packageinstaller")) {
currentApp_for = pakageName.get(i);
return true;
}
}
}
} else {
for (int i = 0; pakageName != null && i < pakageName.size(); i++) {
if (retriveNewApp().equals("com.google.android.packageinstaller")) {
currentApp_for = pakageName.get(i);
Log.e("DSSDSDCSDC", currentApp_for + " LLLLLL::::");
return true;
}
}
}
return false;
}
To get the current activity on foreground above api level 21+ use this code
private String retriveNewApp() {
String currentApp_for_ = null;
if (Build.VERSION.SDK_INT >= 21) {
UsageStatsManager usm = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
List<UsageStats> applist = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
if (applist != null && applist.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<>();
for (UsageStats usageStats : applist) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp_for_ = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
Log.e(">>>>>>>>>><<<", "Current App in foreground is: " + currentApp_for_);
} else {
Log.e("CCC>>C>C>C>", "User not given the permission: " + currentApp_for_);
}
}
return currentApp_for_;
}
Important permission
<uses-permission
android:name="android.permission.PACKAGE_USAGE_STATS"
tools:ignore="ProtectedPermissions" />
now check the current activity is in foreground or not using service
if (isConcernedAppIsInForeground()) {
if (!currentApp.matches(previousApp)) {
// if matches do your activity here..
startActivity(newIntent(context,Draw_Lock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
previousApp = currentApp;
}
}
}
Note: When user clicks on uninstall button of any app alert dialog popups which is known as 'com.google.android.packageinstaller' activity check weather this activity is in foreground or not using service class
It seems Google finally closed all doors for getting the current foreground application package.
After the Lollipop update, which killed getRunningTasks(int maxNum) and thanks to this answer, I used this code to get the foreground application package since Lollipop:
final int PROCESS_STATE_TOP = 2;
RunningAppProcessInfo currentInfo = null;
Field field = null;
try {
field = RunningAppProcessInfo.class.getDeclaredField("processState");
} catch (Exception ignored) {
}
ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> appList = am.getRunningAppProcesses();
for (RunningAppProcessInfo app : appList) {
if (app.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND &&
app.importanceReasonCode == 0 ) {
Integer state = null;
try {
state = field.getInt( app );
} catch (Exception ignored) {
}
if (state != null && state == PROCESS_STATE_TOP) {
currentInfo = app;
break;
}
}
}
return currentInfo;
Android 5.1.1 and above (6.0 Marshmallow), it seems, killed getRunningAppProcesses() as well. It now returns a list of your own application package.
UsageStatsManager
We can use the new UsageStatsManager API as described here but it doesn't work for all applications. Some system applications will return the same package
com.google.android.googlequicksearchbox
AccessibilityService (December 2017: Going to be banned for use by Google)
Some applications use AccessibilityService (as seen here) but it has some disadvantages.
Is there another way of getting the current running application package?
To get a list of running processes on Android 1.6 - Android 6.0 you can use this library I wrote: https://github.com/jaredrummler/AndroidProcesses The library reads /proc to get process info.
Google has significantly restricted access to /proc in Android Nougat. To get a list of running processes on Android Nougat you will need to use UsageStatsManager or have root access.

private String printForegroundTask() {
String currentApp = "NULL";
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager usm = (UsageStatsManager)this.getSystemService("usagestats");
long time = System.currentTimeMillis();
List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000*1000, time);
if (appList != null && appList.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : appList) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
} else {
ActivityManager am = (ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> tasks = am.getRunningAppProcesses();
currentApp = tasks.get(0).processName;
}
Log.e("adapter", "Current App in foreground is: " + currentApp);
return currentApp;
}
Use this method for getting foreground task.
U will need an System Permission "android:get_usage_stats"
public static boolean needPermissionForBlocking(Context context){
try {
PackageManager packageManager = context.getPackageManager();
ApplicationInfo applicationInfo = packageManager.getApplicationInfo(context.getPackageName(), 0);
AppOpsManager appOpsManager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
int mode = appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS, applicationInfo.uid, applicationInfo.packageName);
return (mode != AppOpsManager.MODE_ALLOWED);
} catch (PackageManager.NameNotFoundException e) {
return true;
}
}
IF user enable this in setting -> Security-> app with usage access. After that u will get foreground task. Similar process Clean matser by Cheetahamobile

Take a look at https://github.com/ricvalerio/foregroundappchecker, it might be what you need. Provides sample code, and takes away the pain of having to implement cross version foreground detector.
Here are two samples:
AppChecker appChecker = new AppChecker();
String packageName = appChecker.getForegroundApp();
Or regularly check:
AppChecker appChecker = new AppChecker();
appChecker
.when("com.other.app", new AppChecker.Listener() {
#Override
public void onForeground(String packageName) {
// do something
}
)
.when("com.my.app", new AppChecker.Listener() {
#Override
public void onForeground(String packageName) {
// do something
}
)
.other(new AppChecker.Listener() {
#Override
public void onForeground(String packageName) {
// do something
}
)
.timeout(1000)
.start(this);
Google limited this functionality for system apps only. As been reported in a bug ticket, you will need the REAL_GET_TASKS permission to access there.
Applications must now have ...permission.REAL_GET_TASKS to be able to
get process information for all applications. Only the process
information for the calling application will be returned if the app
doesn't have the permission. Privileges apps will temporarily be able
to get process information for all applications if they don't have the
new permission, but have deprecated ...permission.GET_TASKS Also,only
system apps can acquire the REAL_GET_TASKS permission.
Just throwing out a potential optimization to what I imagine is a heavily copy-pasted bit of code for detecting the top-most application on Android M.
This
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager usm = (UsageStatsManager)this.getSystemService("usagestats");
long time = System.currentTimeMillis();
List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000*1000, time);
if (appList != null && appList.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : appList) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
}
Can be simplified to this
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager usm = (UsageStatsManager) context.getSystemService(
Context.USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
List<UsageStats> appStatsList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY,
time - 1000 * 1000, time);
if (appStatsList != null && !appStatsList.isEmpty()) {
currentApp = Collections.max(appStatsList, (o1, o2) ->
Long.compare(o1.getLastTimeUsed(), o2.getLastTimeUsed())).getPackageName();
}
}
I found myself using this code in a 2 second loop, and wondered why I was using a complex solution that was O(n*log(n)) when a more simple solution was available in Collections.max() which is O(n).
public class AccessibilityDetectingService extends AccessibilityService {
#Override
protected void onServiceConnected() {
super.onServiceConnected();
//Configure these here for compatibility with API 13 and below.
AccessibilityServiceInfo config = new AccessibilityServiceInfo();
config.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED;
config.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
if (Build.VERSION.SDK_INT >= 16)
//Just in case this helps
config.flags = AccessibilityServiceInfo.FLAG_INCLUDE_NOT_IMPORTANT_VIEWS;
setServiceInfo(config);
}
#Override
public void onAccessibilityEvent(final AccessibilityEvent event) {
if (event == null ) {
return;
} else if(event.getPackageName() == null && event.getClassName() == null){
return;
}
if (activityInfo != null){
Log.d("CurrentActivity", componentName.flattenToShortString());
}
}
private ActivityInfo tryGetActivity(ComponentName componentName) {
try {
return getPackageManager().getActivityInfo(componentName, 0);
} catch (PackageManager.NameNotFoundException e) {
return null;
}
}
#Override
public void onInterrupt() {
}
}
}//`enter code here`uses-permission android:name="android.permission.BIND_ACCESSIBILITY_SERVICE" />
<uses-permission android:name="android.permission.GET_TASKS" />
Then start the service and app accessibility on in your device
setting->accessibility->App
on that service.
Please try to use getRunningServices() instead of getRunningAppProcesses() method.
ActivityManager mActivityManager = (ActivityManager) getSy stemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> appProcessInfoList = mActivityManager.getRunningServices(Integer.MAX_VALUE);
I use the code below to get the application package name.
But when I swipe the notification bar, it will take the name of the application package running in the notification bar.
Or where applications are updating the new version, it will take the name of the application package.
I tried it on Android 5 get exact results open application package name.
So how to get the name of the application package is currently running on Android open 6
public static String printForegroundTask(Context context) {
String currentApp = "Null";
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager usm = (UsageStatsManager) context
.getSystemService("usagestats");
long time = System.currentTimeMillis();
List<UsageStats> appList = usm.queryUsageStats(
UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
if (appList != null && appList.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : appList) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp = mySortedMap.get(mySortedMap.lastKey())
.getPackageName();
}
}
} else {
ActivityManager am = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
currentApp = am.getRunningTasks(1).get(0).topActivity
.getPackageName();
}
return currentApp;
}
whenever I try to query the Usage Stats of the UsageStatsManager I can correctly get the last running app. However, if I pull down the status bar and there is a new notification, the last used app (based on UsageStats) will change to that of the notification. As a result, I get false alarms that the foreground application has changed.
I can't seem to find a way to filter those specific draws. Any ideas?
Right now, I query for the foreground app with the following code. The problem exists only in Marshmallow (5.X works correctly).
UsageStatsManager mUsageStatsManager = (UsageStatsManager) rotationManager.getSystemService("usagestats");
long time = System.currentTimeMillis();
// We get usage stats for the last 10 seconds
List<UsageStats> stats = mUsageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 2, time);
// Sort the stats by the last time used
if (stats != null) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : stats) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
foregroundApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
You can query the usageEvent to check if the last active app's event is UsageEvents.Event.MOVE_TO_FOREGROUND.
After you get the foregroundApp, you can refer to the following code:
UsageEvents usageEvents = mUsageStatsManager.queryEvents(time - 100 * 1000, time);
UsageEvents.Event event = new UsageEvents.Event();
// get last event
while (usageEvent.hasNextEvent()) {
usageEvent.getNextEvent(event);
}
if (foregroundApp.equals(event.getPackageName()) && event.getEventType() == UsageEvents.Event.MOVE_TO_FOREGROUND) {
return foregroundApp ;
}
In android 6.0 os, getUsageStats function giving list size zero. For confirmation, you can check any lock app from play store. Those app are not working in android 6.0.
Take a look at https://github.com/ricvalerio/foregroundappchecker, it might be what you need. Provides sample code, and takes away the pain of having to implement cross version foreground detector.
