For an Android app, usually Google Play Market is used as a distribution platform (market).
To do so, you need to generate .apk in Android Studio, create an application in Play Market console, put your .apk into the Play Market applicaiton.
You can also use third-party distribution platforms, like Firebase App Distribution, the process is more or less the same there.

Regarding Iroha SDK for Android app, it doesn't affect the distribution process, so you can you it without any issues

OK, thanks for quick and accurate answer.

Hello, I am developing an Android app and trying to use the iroha-java client. Right now I am facing an issue that I can't send Queries. Transactions work fine, but queries always produce errors when sent with IrohaAPI.query(myQuery).

The errors are always "Unsupported value: iroha.protocol.QueryResponse.query_hash" even though everything seems correct. If I pass clearly incorrect values like say wrong username the response is "Unsupported value iroha.protocol.QueryResponsr.error_response" so I believe I pass everything correctly but I may be wrong. Can you possibly help with that? It would be much appreciated.

What versions of iroha and iroha-java are used? Could you also share some code. Have you followed examples or iroha-java tests?
16:49:46@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
Iroha-java is : 'com.github.hyperledger.iroha-java:client:6.0.0'. Iroha itself is the latest stable release from dockerhub so 1.1.1 . I have followed the examples
16:51:14@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
val api = IrohaAPI( "IP", 50051)
16:51:31@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
val myQuery = Query.builder("test2@ImpiloLogTest", 1).getAccountAssetTransactions("test2@ImpiloLogTest" , "login_attempt#ImpiloLogTest" , 5 , null).buildSigned( Utils.parseHexKeypair("key1","key2"))
val res = api.query(myQuery)

I wasn't really able to reproduce the issue:
(Kotlin)

val keyPair = Ed25519Sha3().generateKeypair()
val domainName = "ImpiloLogTest"
val accountName = "test2"
val accountId = "$accountName@$domainName"
val assetName = "login_attempt"
val assetId = "$assetName#$domainName"
println(
        iroha.api.transaction(
                Transaction.builder(GenesisBlockBuilder.defaultAccountId)
                        .createDomain(domainName, defaultRoleName)
                        .createAccount(accountName, domainName, keyPair.public)
                        .createAsset(assetName, domainName, 0)
                        .sign(defaultKeyPair).build()
        ).blockingLast()
)

println(
        iroha.api.query(Query.builder(accountId, 1L)
                .getAccountAssetTransactions(accountId, assetId, 5, null)
                .buildSigned(keyPair))
)

Maybe there are some Android related stuff or dependencies mess taking place.
@mrZizik have you ever encountered the error described?

09:12:29@gitter_sorabot:matrix.orgsorabot (Gitter) Bogdan Mingela via telegram
Could you share your genesis block or code of transactions as well?
09:19:25@gitter_sorabot:matrix.orgsorabot (Gitter) Bogdan Mingela via telegram
I think there is an issue that QueryResponse cannot be assigned, could you just print or log api.query(myQuery)? what language are you using in your Android project? Kotlin or Java with lombok etc?
09:19:51@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
First of all thank you for taking the time to help me. Secondly now that you mention it there was a dependecy issue with the following files and resolved it like this '''packagingOptions {
pickFirst 'META-INF/INDEX.LIST'
pickFirst 'META-INF/io.netty.versions.properties'
}'''
09:21:11@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
To be specific we are using flutter and the android project itself is in Kotlin, but this shouldn't prove an issue
09:29:40@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
If you mean the transactions that work with no issue, the code is exactly the same as it is in the examples just with our information.
09:32:34@gitter_sorabot:matrix.orgsorabot (Gitter) Bogdan Mingela via telegram
Could you try using QueryAPI instead of IrohaAPI for your query? There are different return value types of the methods. I'm just interested in a class scope of the issue. So just do smth like as an experiment
val queryAPI = QueryAPI(api, "test2@ImpiloLogTest", Utils.parseHexKeypair("key1","key2"))
val res = queryAPI.getAccountAssetTransactions("test2@ImpiloLogTest", "login_attempt#ImpiloLogTest" , 5)

Great, thanks! we will do it!
09:42:06@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
@mingela I tried using it the new method and the result is still an error albeit a different one. """ UNAVAILABLE: io exception"""
09:42:13@gitter_sorabot:matrix.orgsorabot (Gitter) Sara via telegram
Thank you!
09:42:58@gitter_sorabot:matrix.orgsorabot (Gitter) Bogdan Mingela via telegram
Are you sure Iroha peer is available?
10:03:10@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
Aa , there is a small issue with that right now, let me fix it and I'll get back to you. Thanks a lot!

Hello.
10:50:34@gitter_sorabot:matrix.orgsorabot (Gitter) Ali Abdulmadzhidov via telegram
Looks valid

https://github.com/mrZizik/iroha-android/blob/iroha_pure_java_version/app/src/main/java/jp/co/soramitsu/irohaandroid/data/transfer/TransferRepositoryImpl.kt

Here is example of Query from iroha-sample app.

Maybe your assetId or accountId are wrong. Also you should check version compatibility between iroha and iroha-java lib
17:49:19@gitter_sorabot:matrix.orgsorabot (Gitter) Michael Kontoulis via telegram
Hmm ,assetsid and account seem to be fine, I can do this fine through the python client @mingela can you tell me what version of iroha and java library you used when you tried to reproduce the error?
17:54:23@gitter_sorabot:matrix.orgsorabot (Gitter) Bogdan Mingela via telegram
Iroha-java 6.1.0, Iroha both 1.1.0 and 1.1.1 work
20:36:25@gitter_sorabot:matrix.orgsorabot (Gitter) Ali Abdulmadzhidov via telegram
if you say which versions are you using, i can set up them locally on my system and try it.
