I have to admit that my Asus tablet doesn't have a security, allow apps function within.
Any ideas on what other function might do this?

Rusty ANDROID VERSION no B4A Version

 

[Rusty]

oops. Being illiterate is really tough
Thanks. I'll try it on a "newer" device

[MarcoRome]

If you see in your log you have this message:

java.lang.NoClassDefFoundError: android.app.usage.UsageStatsManager

So i think that you utilize device with Android Version < 5.0

 

[Rusty]

You are right, it is. It is a 4.4.2
I'm trying it right now on 6.0 (Marshmallow).
Thanks!

 

[DonManfred]

Thanks. I'll try it on a "newer" device

https://developer.android.com/reference/android/app/usage/UsageStatsManager.html
Device must be Api 21+

 

[Rusty]

Thanks Don,
I installed it on a Marshmallow tablet (api 23) and it works great
Good work!
Rusty

Hello,

I'm using it for blocking access to the standard webbrowser on devices with Android 5, Android 6 and Android 7 and it works nice.

One question remains: one needs to Add you App to the Exceptionlist in Android Security settings, Settings/Security/Allow app use of Usage stats

is it possible to read the settings and, if needed, go to the settings screen?

 

[DonManfred]

is it possible to read the settings

not that i know of.

You can use this code:

Dim usage1 As List = usm.queryUsageStats(starttime,endtime)
    Log("Return if list is populate: " & usage1.Size)
    Dim check As Int = usage1.Size
    If check = 0 Then
        Msgbox("In Android 5.0 or above, permission must be granted for Lock to work correctly. Scroll to find ProtectYourApp and turn it ON","Look requires permission")
        ToastMessageShow("In Android 5.0 or above, permission must be granted for Lock to work correctly. Scroll to find ProtectYourApp and turn it ON", True)
        Dim StartIntent As Intent
        StartIntent.Initialize("android.settings.USAGE_ACCESS_SETTINGS", "")
        StartActivity(StartIntent)
        'Per Notifiche
        Dim In As Intent
        In.Initialize("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS", "")
        StartActivity(In)
    End If

Maven artifact not found: android.arch.lifecycle/livedata-core

open B4A SDKManager and install them enter "livedata" in the searchfiel and install all found items.

For any other issue create a new thread in the Questionsforum.

Both on version : 1.1.0

Good evening

Thank you very much for this useful Library!

I have a probably simple to fix issue:
while working with this Library, it is very verbose because it creates many log-entries if queryAndAggregateUsageStats or queryUsageStats is called, e.g:

…
Usage stats for: org.omnirom.omnijaws
Usage stats for: com.skype.raider
Usage stats for: com.google.android.ext.services
Usage stats for: com.android.providers.telephony
Usage stats for: com.android.providers.calendar
Usage stats for: com.android.providers.media
…

This makes it hard to debug the application which uses this Library.

Could you eventually provide us with the code so that we can remove the log() calls ourselves (and of course publish it again),
or could you please publish a version that does not create any Log() entries itself?

Thanks a lot for your support,
kind regards,
Thomas

Sorry, but unfortunatly i lost the source last year due to a HDD Crash.

Sorry, but unfortunatly i lost the source last year due to a HDD Crash.

Thank you very much for your answer to this old subject / new question!,
I'm very sorry that you had suffered this damage.

If I find some time, I'll try to decompile it and test how it looks like. Maybe the effort is bearable

Kind regards, Thomas
