fix(home screen): screen time corrected by filtering only today's values
Check it out now.
Launcher apps are being filtered out.
In my case, I have 46 minutes shown in the launcher and 41 minutes in Digital Wellbeing.
I've already tried the combination of the changes you've made. So far no luck. I read somewhere that timezone plays a role and should be taken into consideration. Need to test that theory.

An important thing I didn’t notice yesterday is that I accidentally counted time only for the launcher apps instead of filtering them out. 🤦♂️ That’s why you have 0 minutes. With that being fixed. It seems promising. Will test it and play with it further.

I will take a look in a bit and see what mine comes up with on my phone. Testing it on android studio sucks.
firstTimeStamp seems to be having issues and always coming back as 0 where as lastTimeStamp gives data maybe that is what needs using? i could be wrong
Below is the code I am using, along with a blacklist.xml to blacklist apps I don't want displayed in the usage.
I had to blacklist com.opera.browser because it behaves strangely, always showing background hours and not just the time it's actively being used.
fun getTotalScreenTime(context: Context): Long {
val packageManager = context.packageManager
val blacklist = parseBlacklistXML(context)
val currentPackageName = context.packageName // Get current app's package name
// Get start of today in the correct timezone
val startOfToday = Calendar.getInstance().apply {
timeZone = TimeZone.getDefault()
set(Calendar.HOUR_OF_DAY, 0)
set(Calendar.MINUTE, 0)
set(Calendar.SECOND, 0)
set(Calendar.MILLISECOND, 0)
}.timeInMillis
val currentTime = Calendar.getInstance().apply {
timeZone = TimeZone.getDefault()
}.timeInMillis
val usageStatsManager = context.getSystemService(USAGE_STATS_SERVICE) as UsageStatsManager
// Get launcher apps (home screen apps)
val launcherApps = packageManager.queryIntentActivities(
Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME), 0
).map { it.activityInfo.packageName }.toSet()
// Query usage stats for today
val usageStatsList = usageStatsManager.queryUsageStats(
UsageStatsManager.INTERVAL_DAILY, startOfToday, currentTime
) ?: return 0L
return usageStatsList
.filter { usageStats ->
val packageName = usageStats.packageName
// Exclude launcher apps, blacklisted apps, and current app
packageName != currentPackageName &&
!launcherApps.contains(packageName) &&
!blacklist.contains(packageName) &&
usageStats.totalTimeInForeground > 0 &&
// Ensure usage happened today
startOfToday <= usageStats.lastTimeUsed
}
.sumOf { it.totalTimeInForeground }
}
private fun parseBlacklistXML(context: Context): List<String> {
val packageNames = mutableListOf<String>()
// Obtain an XmlPullParser for the blacklist.xml file
context.resources.getXml(R.xml.blacklist).use { parser ->
while (parser.eventType != XmlPullParser.END_DOCUMENT) {
if (parser.eventType == XmlPullParser.START_TAG && parser.name == "app") {
val packageName = parser.getAttributeValue(null, "packageName")
packageNames.add(packageName)
}
parser.next()
}
}
return packageNames
}
fun formatMillisToHMS(millis: Long, showSeconds: Boolean): String {
val hours = millis / (1000 * 60 * 60)
val minutes = (millis % (1000 * 60 * 60)) / (1000 * 60)
val seconds = (millis % (1000 * 60)) / 1000
val formattedString = StringBuilder()
if (hours > 0) {
formattedString.append("$hours h ")
}
if (minutes > 0 || hours > 0) {
formattedString.append("$minutes m ")
}
// Only append seconds if showSeconds is true
if (showSeconds) {
formattedString.append("$seconds s")
}
return formattedString.toString().trim()
}
Another option is to just ignore all this and use launcher screen on/off time to calculate the total screen time. Won't even need the screen time permission. 😅
@CreativeCodeCat ... Does it work with the Opera being blocked? And if, how much is the time off in comparison to the digital wellbeing?
Because so far I have only one minute difference.

Ya that will work fine when you just want to track whole time but myself I am also displaying each apps usage time.

I installed Opera a few hours ago, and it still works fine. How can I replicate the issue? Could you describe it in more detail? @CreativeCodeCat
After a full day of testing on both my phone and the Android emulator, everything is working as expected. The difference is usually just a minute. @tanujnotes, give my latest changes a try!
PS: I have Opera installed, and no problems so far.
fun getTodaysScreenTime() {
viewModelScope.launch {
val startOfToday = Calendar.getInstance().apply {
timeZone = TimeZone.getDefault()
set(Calendar.HOUR_OF_DAY, 0)

set(Calendar.SECOND, 0)
set(Calendar.MILLISECOND, 0)

val currentTime = System.currentTimeMillis()
val usageStatsManager = appContext.getSystemService(USAGE_STATS_SERVICE) as UsageStatsManager
val packageManager = appContext.packageManager
// Get launcher apps
val launcherIntent = Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME)
val launcherApps = packageManager.queryIntentActivities(launcherIntent, 0)
.map { it.activityInfo.packageName }
.toSet()
val stats = usageStatsManager.queryUsageStats(
UsageStatsManager.INTERVAL_DAILY,
startOfToday,
currentTime
)
val today = Calendar.getInstance()
val todayYear = today.get(Calendar.YEAR)
val todayDayOfYear = today.get(Calendar.DAY_OF_YEAR)
val totalTimeInMillis = stats
.filter { stat ->
// Exclude launcher apps
!launcherApps.contains(stat.packageName) &&
// Filter for today's stats
Calendar.getInstance().apply {
timeInMillis = stat.firstTimeStamp
}.let { statCalendar ->
val statYear = statCalendar.get(Calendar.YEAR)
val statDayOfYear = statCalendar.get(Calendar.DAY_OF_YEAR)
statYear == todayYear && statDayOfYear == todayDayOfYear
}
}
.sumOf { it.totalTimeInForeground }
val formattedTime = appContext.formattedTimeSpent(totalTimeInMillis)
screenTimeValue.postValue(formattedTime)
}
}
this is if i don't block opera that's why I have it blocked atm.
Launcher (1) is unblocked and Launcher (2) is blocked

Interesting! Which version of Opera do you have? Are you referring to the standard Opera browser from Google Play? Are you using any plugins? I’d like to replicate the issue so I can inspect the data.
I do have Opera installed, but as you can see from my previous messages, it doesn’t seem to affect anything.
ya just the basic opera from play store no plugins. it could be fairphone tbh.
@OndrejKulhavy Have you pushed the latest changes in your repo? Edit: I've copied the code in your comment. Will update tomorrow. Thank you!
Unfortunately, that didn't work for me (Pixel, Android 15).
I'm trying an alternate way to get the screen time which shows promise (using UsageEvents instead of UsageStats). Let's see how it goes.
