Android app won't start, iOS app works fine.. (Xamarin) #5766

blueoceandev created 5 years ago

I am starting work on the mobile portion of our solution.. I have the iOS app starting up and authenticating (literally all I have done was point is update the ApiUrlConfig.DefaultHostUrl to point at our Development instance of our API in Azure). However, on android the app fails to load completely, the splash screen comes up, the application stalls, and then it crashs.. I have attached the android device logger, and get the following exception.

Time Device Name Type PID Tag Message 10-12 19:35:23.544 my_device Error 7061 AndroidRuntime android.runtime.JavaProxyThrowable: Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: .

Again, all I have done to the code that is downloaded from the template is update ApiUrlConfig.DefaultHostUrl to point to our dev API instance in azure, and the code works fine on the iOS emulator.

Is there a specific Android SDK I should be building to ( I have tried, P & 8.1)

Thanks Josh

looks like it doesn't retrieve some Json response from server. try to install the application on a real device and make sure you can navigate to the WebApi address from your internal browser of the mobile.

The Android Emulator can hit the service just fine.. I triple checked all the networking... I tried to use fiddler as a proxy to get some data on the actual request but that failed.. I am not sure if it failed for the same reasons since we have SSL on..

I haven't tried a physical device yet, but there are no signs as to why this would fail in the emulator.

HTTPS can be the issue! See this

It replaces localhost but HTTPS remains.

private const string DefaultHostUrl = "http://localhost:22742/"; //TODO: Replace with PROD url.

That is the first thing I changed, in fact its the ONLY thing I changed in the codebase (see first comment). I am pointing at a deployed development URL that is in Azure and feeds our dev release of our Web UI and works with the iOS build of the exact same soursecode.

Yah just tested on my S9 and it failed the same way.. Here are all the log entries under "MonoDroid"

Are these tickets private? If so, I can send you the URL to our Dev azure deployment.

Confirmed it fails on http as well as https so its not https :(...

Again this is a website that can be hit by anyone on the planet including the mobile device.

Here is a build log if this is useful.. There are a couple of assembly conflicts that things are building despite of, I am not sure I am used to seeing those on most of my other work so maybe they are related? anyway... Let me know what else might be worth looking into.

Hey! Solved your problem.

I've done the below changes in my sample project, to get things done with connecting your WebAPI endpoint, .

ApiUrlConfig.DefaultHostUrl =  "https://xxxxx.azurewebsites.net/";  //you do not need this change.
AbpZeroTemplateConsts.LocalizationSourceName = "RTS"; //you do not need this change.

The crucial change is disabling `Accept-Encoding` header in `AbpApiClient`.

AbpApiClient.cs#L399

Why do you need to disable this line?

Because Azure is sending responses in Gzip format. So the client has to decompress it. No problem until now. The problem is the library used in AspNet Zero Xamarin application (ModernHttpClient) requires to disable the Accept-Encoding request header for Android. You can read the related issue on their GitHub repo.

So the final code must be like below;

private void AddHeaders(string accessToken)
        {
            _client.HttpClient.DefaultRequestHeaders.Clear();

            _client.WithHeader("Accept", "application/json");
            _client.WithHeader("User-Agent", UserAgent);
            // _client.WithHeader("Accept-Encoding", "gzip,deflate");

            if (_applicationContext.CurrentLanguage != null)
            {
                _client.WithHeader(".AspNetCore.Culture", "c=" + _applicationContext.CurrentLanguage.Name + "|uic=" + _applicationContext.CurrentLanguage.Name);
            }

            if (_applicationContext.CurrentTenant != null)
            {
                _client.WithHeader(MultiTenancyConsts.TenantIdResolveKey, _applicationContext.CurrentTenant.TenantId);
            }

            if (accessToken != null)
            {
                _client.WithOAuthBearerToken(accessToken);
            }
}

Note: The owner of the library says it works as expected in IOS but for Android they use OkHttp client which doesn't like Accept-Encoding header. So I commented out the line.

Test the change with IOS & Android and get me back with the results.
