Hi, thank you for response. Yes, I have checked External Storage setting for my app and on older Android device it works as expected. From the information I was able to gather I understand that the problem is in new permissions for Android - Qt itself had issue with it: Qt Android Bug Tracker This thread ends with the question: Is there a plan to make this API available in QML? Sadly without answer... Please can somebody confirm that is able to store data on SD card for Android 7.x ? Primary external storage works for my app, but we use quite a lot of data and older devices don't have enough space here. ... View more

It seems that, it is because of the changes in Android API from 4.4 version: Traditional Storage  |  Android Open Source Project  Multiple external storage devices Starting in Android 4.4, multiple external storage devices are surfaced to developers through  Context.getExternalFilesDirs() ,  Context.getExternalCacheDirs() , and  Context.getObbDirs() . External storage devices surfaced through these APIs must be a semi-permanent part of the device (such as an SD card slot in a battery compartment). Developers expect data stored in these locations to be available over long periods of time. For this reason, transient storage devices (such as USB mass storage drives) should not be surfaced through these APIs. The  WRITE_EXTERNAL_STORAGE  permission must only grant write access to the primary external storage on a device. Apps must not be allowed to write to secondary external storage devices, except in their package-specific directories as allowed by synthesized permissions. Restricting writes in this way ensures the system can clean up files when applications are uninstalled. So the question is how to get SD card storage for the app to be able to write data on it. Thank you. ... View more

Hi, thank you for clarification. I see, I have written my last post quite confusing. Workflow with the app is this: SDE geodatabase with the data, generating offline *.geodatabase package with Python every week from main SDE (it is a file up to 1GB), now we try to solve how to get the new package of data to Android tablet: manualy copy the *.geodatabase to Android tablet (we use this now), upload the package to Portal (with Python) and let AppStudio to download it from portal? (Does AppStudio QML SDK have classes for browsing Portal items and dowload them?) copy the package to dedicated web server (with Python) and let AppStudio do download it from it? (HTTPS, Should at least Basic Authentication work with NetworkRequest object?) Well I hope I put it on the right track. Thanks, Zdenek J. ... View more

Hi all, I would like to have one more question: is there any chance to use NetworkRequest object to download files from secured web folder, e.g. HTTPS Basic Authentication? Or I am not sure if it would be possible to upload our files (around 750MB each) to Portal and then downloaded from Portal with portal credentials in the play. Thanks for comments on this.

Hi Stephen Quan​, thank you for this reference, I wasn't able to find it on my own in the help/doc. It is in ArcGIS.AppFramework. There is a Esri Sample using it as well: http://www.arcgis.com/home/item.html?id=bfb0dec97a254a0d9d609a3e3cc95598 - better to search it through AppStudio itself. Thanks, I will give that a try.

Hi, on Android (and Windows7, and it should be everywhere) I've manged the right path for data with help of app.settings.value function. I can't find online help, but ​settings is property of ​App object from AppStudio Framework. This settings is read from json file, which is on Android on <device specifik>/ArcGIS/AppStudio/Settings/<app_id>.json app_id hash string can be found in iteminfo.json in the folder of the app with key id. So my code in app looks like:     Geodatabase {         id: localData         path: app.settings.value("gdbData")     } where "gdbData" is the key in my setting json. ... View more

So, I installed Operation Dashboard on another computer and then copy whole folder with name "oper...app_f464941b06bea132_000a.0003_790a069f1fec1fdc" to the first one (to the same hash folders names). Now OD is possible to start. ... View more

Well, this seems to me like a good point: from manifest file it looks like that the file CoherentUI_Host.exe is downloading separately - from this point of view it make sense. How to get the Dahboard on the computer? ... View more

Hi all, now I have very similar problem with the last release of Operations Dashboard. I am installing on Windows Server 2008 R2 Standard. After downloading whole package I get this "Application validation did not succeed. Unable to continue." error. Detailed log is attached. I delete everything from C:\Users\<username>\AppData\Local\Apps\ folder and from registry according to 41798 - Cannot install Operations Dashboard, but nothing helped. Thank in advanced. ... View more
