captions of fields for measures should be the same during entering and presentation

• 01 Scan Date //filled automatically
• 02 Scan Location
• 03 Height
• 04 Weight
• 05 MUAC
• 06 Head Circumference
• 07 Oedema

List of measures should be sorted with latest on top, oldest on the bottom of the list

As a data scientist working with the database I want a simple way to determine what kind of data point I have when I see just the ID.

Therefore we already implemented the following schema:
UUID of App_object-type_epoch ms_random string

but for person it is the last name instead of "person"
and for measures it should be "manual" or "scan" instead of "measure"

sometimes the qrcode of a person is set to null. It looks like it happens sometimes when swiping down on the person list.

• remove swipe down as it is not necessary anymore with LiveData´
• make sure there are no direct reads / writes to Firebase Database outside of Sync
• throw Exception and make call to Crashlytics when loading a person with qrcode null

try {
    methodThatThrows();
} catch (Exception e) {
    Crashlytics.logException(e);
    // handle your exception here
}

• All Strings that are shown to the user must be in strings.xml
• As a user i want to be able to choose my main language (default from system language)
• the app should be able to display hindi हिन्दी letters

feed list of local files to upload service at startup?
How does Service maintain it's list of files for uploading? Through restarts?

as a user i want to see names, height and weight of the children in the overview

the personaldata in the recyclerview should show the height and weight from the last measures where both were not null or 0.0

see Crashlytics Issue and Stacktrace below

steps to reproduce:

• start App (online)
• add manual measures
• wait a few minutes

• check qr code v132-test1

the growth chart is over-expanded because of the scan measurement.
scan measurement should be current timestamp / days of age

as a user when i save a manual measurement i want the screen to change to the GROWTH tab to see the measurement on the chart

• saving a manual measurement should switch tab/fragment to GROWTH
• newly added measurement should appear to show the user the progress
• if there is only one measurement it should show up as a big black dot

as a user i want to know where a child was scanned the last time.

currently lastLocation is not set in measures:
https://console.firebase.google.com/u/0/project/child-growth-monitor-dev/database/firestore/data~2Fpersons~2Fc99eac07f31db1e7_test10_1529077465187_J04sSXrt2CLyyIbs~2Fmeasures~2Fc99eac07f31db1e7_measure_1529077530408_bOedQdTFsxQBRQ7P

how to reproduce: set location in manual measurement - it is not saved

only write/overwrite lastLocation on person when location of measure is not null or ""

make manual measure input easier

default values/input formats should be:

• height: 0.0 cm
• weight: 0.0 kg expandable to 12.595 kg
• muac: 0.0 cm
• head circumference: 0.0 cm

currently when entering manual measures floats are not exact

height: 95
headCircumference: 56.9
muac: 26.1
weight: 22.6

the backend saves:

height: 95
headCircumference: 56.90000152587891
muac: 26.10000038146973
weight: 22.60000038146973

All values must be saved exactly with the precision that they have been entered, minimum of one digit after the point:

height: 95.0
headCircumference: 56.9
muac: 26.1
weight: 22.6

for values above 120 and values with less then .1 precision a tooltip (similar to currently "please input height" etc. should appear:

• tooltip for height:

- value in kilograms
- at least one digit after the decimal point
- i.e. 12.595

• tooltip for height, muac, head circumference:

- value in centimeters
- use millimeter precision
- i.e. 95.6

example 1 to 2

first test device v1.3.2 created persons

data was synced to firebase.

second test device 1.3.1 did not get the new person data (incompatible to Room?)

1. Use default camera app (intent) to take picture of the document?
2. check for barcode using https://firebase.google.com/docs/ml-kit/read-barcodes
3. show picture to the user and ask if the document is clearly readable
4. save picture in local storage
5. notify FirebaseUploadService of a new file to upload

https://console.firebase.google.com/u/0/project/child-growth-monitor-dev/crashlytics/app/android:de.welthungerhilfe.cgm.scanner/issues/5b41de696007d59fcdef2131?time=last-hour&sessionId=5B41DCBE0270000126040F39759146DD_DNE_0_v2

• the local room database should be a complete copy of the cloud firestore database after syncing
• locally stored data should be uploaded to cloud firestore when a connection is available

• use MPAndroidChart "Time Chart" but with multiple lines like the "Multiple Lines Chart" Example
• start with Age/Height --> Length/height-for-age

include the following files as a static asset into the app:
for girls: http://www.who.int/childgrowth/standards/lhfa_girls_p_exp.txt
for boys: http://www.who.int/childgrowth/standards/lhfa_boys_p_exp.txt

• draw lines from day 0 to current age in days + 100 for the data in the following columns
  • P3
  • P15
  • P50
  • P85
  • P97

It should look something like this for a child that is 5 years old. For younger children the chart is cut off.
http://www.who.int/childgrowth/standards/cht_lhfa_girls_p_0_5.pdf

• also draw a thick black line for the measurements of the child

do the same with

• "Age / Weight" --> "Weight-for-age"

• Weight-for-age (girls)

• Weight-for-age (boys)

• "Height / Weight --> "Weight-for-height"

• Weight-for-height (girls)

• Weight-for-height (boys)

• new chart "Weight-for-length"

• Weight-for-length (girls)

• Weight-for-length (boys)

• new chart "Head circumference-for-age"

• Head circumference-for-age (girls)

• Head circumference-for-age (boys)

• new chart "Arm circumference-for-age"

• Arm circumference-for-age (girls)

• Arm circumference-for-age (boys)

add progress bar to RecorderActivity

• set visible and to 0 percent in BABY_FULL_BODY_FRONT_SCAN, BABY_LEFT_RIGHT_SCAN, BABY_FULL_BODY_BACK_SCAN
• set to 50 percent when FAB is touched to start recording (fab = red)
• set to 100 percent when the FAB is touched again to stop recording

100% probably will not be visible because the progressbar should be hidden again in the onboarding steps: BABY_FULL_BODY_FRONT_ONBOARDING, BABY_LEFT_RIGHT_ONBOARDING, BABY_FULL_BODY_BACK_ONBOARDING
i will use it to show progress in data collection instead of just using it through the FAB.

The Progress Bar should be visible on top of the camera picture, something like this:

As this problem is not easily reproducible, add some more information to the crashlytics reports:
https://firebase.google.com/docs/crashlytics/customize-crash-reports

• log the user
• log current internet connection state
• log seconds since last connection state change
• log if a sync is currently happening
• log for how long the sync is taking or how long the last sync took

As a User logged into the App i want to make sure that all scan artefacts are being uploaded and that data that is saved in the cloud will be automatically deleted from the device.

To upload all files the app should check the contents of the local storage and build a log table in the local Room database from it.
This log is then used to check if a file was successfully uploaded.
if the file gets set the "delete" flag it can be deleted from the local storage.

• table in room database
  • id
  • type (consent,pcd,rgb)
  • full path and filename
  • hash value (SHA-1)
  • file size
  • date of successful upload
  • CreatedBy
  • boolean delete
• sync with Firestore upload only (don't download logs from other devices)
• is used by the FirebaseUploadService as source of work

after fresh install measures are empty
looks like measures are only uploaded but not downloaded
all measures should be available from the start and be updated via LiveData

the current state should be

after a crash while scanning the app tries to restart into PersonalDataFragment and crashes again because context/person is missing.

• fix https://console.firebase.google.com/u/0/project/child-growth-monitor-dev/crashlytics/app/android:de.welthungerhilfe.cgm.scanner/issues/5b1ea2a86007d59fcd878669?time=last-seven-days&sessionId=5B218ED101D90001111DE39F9369A52A_DNE_0_v2

As a user i want to see the growth for the next 100 days from now on so i can see how the child should be developing

• show chart from day 0 to current day + 100

The service will be used to store and sync:

• picture of the consent of parents with QR code
• scan artefacts
  • mp4 video files from RecorderActivity
  • .vtk or .pcd files with point clouds from RecorderActivity

TODOs:

• use local storage for getting consent pictures
• if consent picture is not available from local storage get it from Firebase Storage
• make it optional to delete files from local storage after sync

• manual measurement show and save automatically
• scan measure save automatically

as a user i want to update the scan location to my current location

RecorderActivity
// TODO better icon for fab

same timestamp for scan and manual measures that belong together

As a nutritionist i need to know which user added which measurement in order to document the nutrition survey and do statistical analysis on accuracy of measurements.

save currentUser with each document (person/measurement)
every person document/dataset and every measures document/dataset should have the userID of the creator of the document/dataset

the UUIDs saved with each object in their ID can change. Also Users can switch phones. In any case we have no relation between UUIDs and logged in user, so we need additional createdBy fields.
String createdBy = mAuth.getCurrentUser().getEmail();

• in Room database Person

• in Room database Measure

• where is the mapping between Room database and Firestore?

as a user i want to know when i have filled out all fields in order to save current persons data.
as i user i want to know that the persons data has been saved so i can scan and measure the person.

the save button (btnNext in fragment_personal.xml) in the CreateDataActivity

• when pressed while active (green) should save person and go to measures tab
  if easy to do:
• should turn from grey to green when all mandatory fields are filled

also it should give positive affirmation
when person is saved blend in:

• mark as deleted
• deleted by
• remove from local storage
• person
• measures

currently male/female/other
remove other

When trying to login while offline please add an error message/toast
"can not connect"

second manual measurement added

still just one measurement on chart

switching between MEASURES and GROWTH does nothing - switching to PERSONAL...

...triggers a rerender

as a admin i want to delete persons and their measurements that have been created for test purposes.

the problem is to sync the deletion with the local Room databases of the clients

delete from local storage in FirebaseUploadService: // TODO deleteAfterUpload

• RecorderActivity: true (pc/rgb)
• Personal Data Consent: false

remove google_maps_key from repository

• logout
• login
• add person
  • check firebase database for person
  • check firebase storage for consent
• add manual measures
• add scan measures
• save existing person with/without changes (#70)

• trace performance of scanning process (frames per second)
• trace upload performance
• trace writeToFile performance

When a new entry to the Room DB is saved and the device is online (WiFi or mobile-network) the app should immediately sync it to Firestore.

• sync every 5 minutes
• sync when connection changes
• make time period of period sync (5m) part of settings
• user setting for sync (WiFi or mobile / WiFi only)
• Firebase Remote Config for time period (default 5m)
• Firebase Remote Config for sync connection (default WiFi or mobile)

all files should be stored offline and the service #6 should be notified.

• app uses only local database
• document structure in this issue

store sync timestamp in database instead of user preferences

see also #18

In Android Studio Menu:

Analyze --> Inspect code...

• remove all errors
• check warnings

• measure line should only show measures of type: "manual"

x and y labels

• set labels for x and y-axis
  • age --> days
  • height --> cm
  • weight --> kg
  • MUAC --> cm
  • Head circumference --> cm

implement the other charts

• "Age / Weight" --> "Weight-for-age"

• Weight-for-age (girls)

• Weight-for-age (boys)

• "Height / Weight --> "Weight-for-height"

• Weight-for-height (girls)

• Weight-for-height (boys)

• new chart "Weight-for-length"

• Weight-for-length (girls)

• Weight-for-length (boys)

• new chart "Head circumference-for-age"

• Head circumference-for-age (girls)

• Head circumference-for-age (boys)

• new chart "Arm circumference-for-age"

• Arm circumference-for-age (girls)

• Arm circumference-for-age (boys)

Scanning process:

scan QR code, enter personal data, scan, manual measurement.

problem: location is not updated when phone has been moved

https://developer.android.com/training/data-storage/room/migrating-db-versions

the app should work without internet connection and update immediately on database changes without user interaction
