Cannot create Pool using the CreatePoolAsync() function #32

Closed syedshahzebhasnain closed 3 years ago

syedshahzebhasnain commented 3 years ago

Hi,

Hoping somebody could help me out with an issue I am facing. I am trying to create pool using the code mentioned in aries-mobileagent xamarin/src/Osma.Mobile.App/Services/PoolConfigurator.cs.

The code fails on this line : await poolService.CreatePoolAsync(config.Key, filename).ConfigureAwait(false);

I keep getting an IO error while trying to create a pool. Hyperledger.Indy.IOException: An IO error occurred. at Hyperledger.Aries.Ledger.DefaultPoolService.CreatePoolAsync

I am following the same pattern in as in this project to write./read genesis.txn file.

I have also verified that the android device has the correct permissions to read write files

Can you confirm me which version of Android you are using here? The recent versions have a new permission system that can fail silently and impact this particular step (we don't have explicit support for this yet).

Hi @horationunez ,

Thanks for the quick response. I did figure out that if my application targets Android 29, the application fails. However, with Android 28, it works fine.

@syedshahzebhasnain this will work with Android 29, but you will need this line in your manifest:
<application android:requestLegacyExternalStorage="true" android:label="YourAppName"></application>

Hi @horationunez , I already had this snippet android:requestLegacyExternalStorage="true" in the manifest file yet I was still getting the same issue.
