If the user already used an "unblacklisted" app and afterwards add it to the blacklist, then the time account already subtracts the past usage time. This could result in a big amount of minus time.
Describe the solution you'd like
The user add apps to a "delayed"-blacklist, which will start blacklisting the apps from the next day on. But this should only be a feature for the settings. If the user add apps during the onboarding to the blacklist, then these apps should be directly added to the blacklist.
Describe the solution you'd like
When the user enters the Time Credit shop, then the camera should capture an image of the user and analyse the mood out of it. This mood will be shown in the mood selection. If the user feels different to the pre-selected mood by the algorithm, then he can change the selection.
If the user changes the selection, a negative feedback will be propagated to the algorithm. However, if the user doesn't change the selection a positive feedback will be propagated.
The user should be able to disable this automatic mood detection in the settings.
Is your feature request related to a problem? Please describe.
The "today"-icon in the bottom menu is, by most of the users, assoziated to a calendar view.
Describe the solution you'd like
Move the "today" menu item to the overflow menu. Then the icon can be removed and text with the description can be shown.
Create a persistence layer in the domain module.
Extend the readme with more detailed information. (e. g. Environment, function, example)
Configurable (at which time do the steps reset daily)
Every new pull-request and their commits should be tested by a continues integration system (e. g. Travis-CI) with automatic static code analysis and junit tests.
To keep the code coverage in glance, a tool for automatic test analysis is also needed (e. g. Coveralls).

at com.edu.uni.augsburg.uniatron.service.AppTrackingService.delegateAppUsage(AppTrackingService.java:184)
Describe the bug
The app usage time for a specified time range is collected for all apps.
Expected behavior
The app usage time for a specified time range should be collectable only for the apps which are blacklisted.
Possible solution
In the AppUsageDao:
@Query("SELECT (SELECT TOTAL(time_in_minutes * 60) FROM TimeCreditEntity "
+ "WHERE timestamp BETWEEN :dateFrom AND :dateTo) - TOTAL(usage_time_in_seconds) "
+ "FROM AppUsageEntity WHERE timestamp BETWEEN :dateFrom AND :dateTo")
LiveData<Integer> loadRemainingAppUsageTime(Date dateFrom, Date dateTo);Requested charts:
Create a service for the stepcounter which reports all taken steps back to the app
The app should track the emotion of the user when a new time credit is traded. Therefor a dialog after choosing the time credit will ask the user of his emotion.
For a great code quality, we would like to use static code analysis tools like:
Use Travis-CI to publish the new master version with a release tag to GitHub Releases and upload the apk to Google Play Store.
More...
Describe the bug
Due to the battery optimization the app functionality is in some cases blocked.
Additional context
Describe the bug
When the TimeCreditShopActivity is being started multiple times, it takes multiple presses on the back button to get back to the app
To Reproduce
Steps to reproduce the behavior:
alternatively to 1-3 you can just start multiple intents of the shopactivity to test it
4. open the Uniatron app
5. press the back button and watch as you have to close multiple instances of the shop activity
Expected behavior
the shop should close after pressing back once
Based on the apps used, their duration and the steps taken throughout the day, a neural network should be able to preview the user's mood. So basically the emotion that the user gives off is used as a rating for the NN. Thus, one can predict to the user how much he should still move and / or which apps help him to a better mood.
Describe the solution you'd like
The user should be able to group the history entries by date, month and year. By clicking on an item, the (generic) detail view will display the data for the specified date or month or year.
Describe the bug
The default of the tracked emoticon in the history view is always the worst.
Expected behavior
The default emoticon should be neutral.
Additional context
This issue exists, because the Emotions.getAverage(...) always enters the if (x >= 0) because the sql query returns 0 if no value exists.
Describe the solution you'd like
The button of the next- and prev-date button should be not visible, when there is no next/prev date to select.
We should exclude the launcher from being tracked or listed in the blacklist #31
Describe the bug
The names of the TOP 5 apps are displayed with their package names and not the label names. This is happening, because the AppUsage is saved with the app package name as identifier. This means, that the HomeViewModel must be updated to return the app label and not the package name.
Expected behavior
The TOP 5 chart on the home screen displayes the app labels.
Screenshots
With a click on a history item, a detailed view should be opened to display more information about this specific day.
A delightful animation for the detail view would be the animation like google's inbox message.
As a delight startup of the detail view would be a vertical bar chart which depicts the usage time of all apps over a day (x-axis = hours of day 0-23; y-axis = time of usage in minutes).
As an example:
An enhanced design to the final app.
In the new version of the home screen, the user can find all the relevant information above the bottom navigation. The time credit shop is reachable through the orange action button. See the Material Design specs.
The user need's to choose a time credit to buy more usage time. Therefor an overview of all possible credits should be available. These credits shoud be grayed out if they were not available due to less steps. In two columns and five rows every credit has enough place. Maybe it should be discussed whether to create the shop inside a dialog or as a standalone activity (@leonpoint @speedyhoopster3 @anja-h ).
The history elements are more structured then before. The emotion is a highlight in front of the element. By clicking on "Details" the detail view #18 can be accessed. To provide a relative date caption, the DateUtils or a library (e. g. timeago) can be used.
The history should be choosable between year, month and day wise.
The user should be guided through the first steps to set up a basic configuration. Therefor the material design uses Onboarding. A sample library can be found on GitHub.
The introduction screen should display a short preview of the main goal of this app.
The second screen let the user choose his fitness level. This should be displayed in a way like the following screenshot. Notice: Only one choice is possible. Maybe a little image should be placed on this screen.
The third screen contains a pre-selected list of all installed apps on the device. The user can directly choose, which apps will be blacklisted. The circles could contain the App-Icons in four columns.
Describe the bug

Describe the bug
Buying time with step credits doesn't work
To Reproduce
Steps to reproduce the behavior:
Was not able to reproduce.
Describe the bug
The steps of the prior day are shown under the current date value
Describe the bug
Sometimes the dialog for choosing the blacklist apps is empty.
To Reproduce
This error comes up very flexible. For now it is not possible to reproduce the
Expected behavior
The blacklist shows up all the installed apps all the time.
Describe the bug
When an amount of new apps is installed by the user, the notification of Uniatron to add these apps to the blacklist is always override by itself. This means, that only the last installed app is possible to add to the blacklist.
Expected behavior
For every new app, a new notification need's to be shown.
Smartphone (please complete the following information):
Describe the bug
Is Nr. 1 intended?
Nr. 2 is fixed when Nr.1 is resolved.
If the 'History' tab is open, taking steps wil create multiple entries
Steps to reproduce the behavior:
Expected behavior
There should be one entry with the sum of the steps taken
Smartphone (please complete the following information):
When the user installs a new app on the device, Uniatron should detect the installed app automaticly and come up with a dialog to ask, if this app should be also "blacklisted"/blocked on above usage time.
Services will not start itself after the phone has been idle for a long time. This might be caused by Samsung battery optimization, or Android Doze.
To Reproduce
Steps to reproduce the behavior:
Install a second Android Stepcounter app (e.g. https://play.google.com/store/apps/details?id=pedometer.steptracker.calorieburner.stepcounter&hl=de )
In the morning, take some steps and watch and other app increase its steps
After a while, open Uniatron and see the recorded steps are 0.
Expected behavior
The app should countt steps no matter the state or time
Suggestions:
Samsung Galaxy S8, Android 8.0.0
Describe the solution you'd like
Some apps like Chrome, YouTube and some others are pre-installed on the android devices. These apps should also be choosable to blacklist them.
Describe the bug
Buying time credits with your steps will not add them in your credits (or show them in the circular view)
To Reproduce
Steps to reproduce the behavior:
Expected behavior
increase in the time remaining, shown in the circular view
Smartphone (please complete the following information):
Lock social/fun apps after a certain amount of usage.
To get a better accurarcy on the step detection, a connection to the users wearable would be helpful. If the wearable is running under the Android Wear OS a direkt connection could be established. Otherwise a web/rest-api need's to be called to collect the data.
For a good user feeling a visually appealing icon is needed.
We should improve the app lock list. It should

Additional context
Add any other context about the problem here.
Describe the solution you'd like
An option in the settings to choose how long the blacklisted apps can maximal be used per day. For example: A dialog to set a maximal value of time per minutes. The user would enter (e. g.) 120 minutes, which relates to a blocking of all apps after this time was reached.
Buying Credit and entering your emotion will change the emotion of every entry of the current day in the History tab
Steps to reproduce the behavior:
Expected behavior
Only the current History entry should be changed
