middleware-launcher-android's Issues

Helipad uploader throws an exception if no internet connection is available

We should catch this to avoid disrupting the user experience, as it's expected in mobile scenarios.
Add support for SwissbitTSE connected via USB

This is fixed partly by #62.
On newer Android versions this does not work though as manually getting permission from the user is needed to access files on a USB device.
Make LogLevel configurable via Start intent

Trigger Helipad Upload before shutdown

We should trigger a helipad upload before stopping the launcher service here

Issue in fiskaltrust.Middleware.Interface.Client.Grpc

It seems like the dependencies must ne updated in this library.
Compiling a release APK which is using your fiskaltrust.Middleware.Interface.Client.Grpc nuget package is causing issues in production :
System.TypeInitializationException: The type initializer for 'DefaultProxyCache`3' threw an exception. ---> System.ArgumentException: Get Method not found for 'Name'
After we updated all referenced libs to their latest version the issue disappeared.
Together with the issue we discovered another issue, probably related to your reply logic
IPOS client is intialized like this
var retryOptionsGrpc = new RetryPolicyOptions { ClientTimeout = TimeSpan.FromSeconds(2), DelayBetweenRetries = TimeSpan.FromSeconds(1), Retries = 2 };
return GrpcPosFactory.CreatePosAsync(new GrpcClientOptions { Url = new Uri(cashBoxConfiguration.Url), RetryPolicyOptions = retryOptionsGrpc }).Result;
And this is causing this :
System.TypeInitializationException: The type initializer for 'DefaultProxyCache`3' threw an exception. ---> System.ArgumentException: Get Method not found for 'Name'

and so on ;-)
Improve documentation about how to use Swissbit TSE

We should add a section to the README on how the TSE devicePath is resolved and about current USB limitations.
Check android 13+ compatibility

We need to investigate how changes regarding background service handling and file system permissions in newer android versions will affect us.
Tasks

Check if the android launcher works on latest android versions 13 and 14
Test with Fiskaly SCU on emulator using the middleware-demo-android
Test with Swissbit SCU (@TSchmiedlechner can this be done on the emulator? - No)
Document encountered problems in this issue
Data should be uploaded to Helipad when the background service is closed

We should try to upload data when the service is closed to make sure that this still happens, even if the user quits the service after < 5 minutes.
If no internet connection is available, this should be ignored.
Please add Intent Communication possiblity

On Android it is a regular thing for users to enable Airplane Mode.
Once Airplane Mode is enabled the communication to the middleware is impossible for obvious reasons.
To address this a more Android native way should be implemented to make interprocess / inter-app communication possible.
The most common used pattern is communication through intents.
Of course communication to the internal queue will be go down with the Airplane Mode as well. In a closed environment on a single Android device, a direct communication to the queue and scu through a library instead of a http / http2 layer will be needed to solve this issue as well.
Possibility to operate launcher without needing intents

Background

We have a new customer who is interested in implementing the middleware on android. Their software can't use the android intent functions. Using chrome isn't an option either. Normally in these kind of architectures byodc is the best solution, but the cutstomer wants to use a hardware TSE in the german market.
Feature

It would be great if there was an option to use the android launcher without needing intents. The dealer/operator would then be responsible for the running middleware service on the android device.
