Out of memory error when downloading mmpk file

Question

Hi Team,

I am trying to download a mmpk file to my device and then display it. Map size is 93MB.

When i try to call

val portalItemData = portalItem.fetchData()

it throws an exception,

Failed to allocate a 97621424 byte allocation with 25149440 free bytes and 89MB until OOM, target footprint 132745784, growth limit 201326592

If try the sample map download example, its size is 6.4MB. I am able to download it.

Is there any workaround for this?

I'm afraid that if your portal item is secured, it won't be trivial to handle the authentication part (passing the correct token) with your own download implementation. We are going to provide a `ArcGISHttpClient.download()` function as part of our upcoming 200.2.0 release which will handle the authentication part for you. Until then, would you be able to download non-secured (public) portal item data?

Hi Team,

I tried but it throws me a invalid token though its the same auth token I got it when i logged in.

[text={"error":{"code":498,"message":"Invalid token.","details":[]}}]

Let me know if i am missing anything

Hi @Shubham_Sharma , I have tried this URL, just need your confirmation on it. https://www.arcgis.com/sharing/rest/content/items//data?token= Is that API structured is correct?
