Question

I have used this code to get all list apps installed from user. But this code can not get all list app installed only get a part. Examle my phone have app Facebook, Messenger, Telegram ... But this code can not get those apps. My code:

private fun getInstalledApps(context: Context): ArrayList<AppInstall> {
        val mainIntent = Intent(Intent.ACTION_MAIN, null)
        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER)
        val pkgAppsList: List<ResolveInfo> =
            context.packageManager.queryIntentActivities(mainIntent, 0)
        Log.d("TEST_LIST", pkgAppsList.size.toString())
        val res: ArrayList<AppInstall> = ArrayList<AppInstall>()
        for (i in pkgAppsList.indices) {
            val name =
                pkgAppsList[i].activityInfo.applicationInfo.loadLabel(context.packageManager)
                    .toString()
            val drawable =
                pkgAppsList[i].activityInfo.applicationInfo.loadIcon(context.packageManager)
            val bitmap: Bitmap? = drawableToBitmap(drawable)
            val idApp = pkgAppsList[i].activityInfo.packageName
            val appInstall = AppInstall(name, bitmap, idApp)
            res.add(appInstall)
        }
        return res
    }

Is there any other way to get all the apps installed on the phone ?. Thank you !

Did you [add a suitable `` element to your manifest](https://developer.android.com/training/package-visibility/declaring?hl=en#intent-filter-signature)? — CommonsWare, Aug 30 '23 at 10:35
Try using `PackageManager.MATCH_ALL` flag in the `queryIntentActivities()` call, instead of passing `0` as the second parameter and see if that helps. — David Wasser, Aug 30 '23 at 11:29

You need to use the queryUsageStats method if the UsageStatsManager which will return a list of apps over the given interval.

To do so you will need permissions for Usage Access to be set in the manifest. See this question for reference:

android:name="android.permission.PACKAGE_USAGE_STATS"
