Hi guys, im getting this error in the app, and i cant understand what is happening. Tangem is offline? Its something in my app or device? The message is too generic.

Execution failed for task ':app:checkDebugAarMetadata'.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
Could not find com.github.tangem.tangem-sdk-android:android:3.8.2.

Hi, We has problems with the Tangem SDK version in the Flutter Tangem SDK.
for the moment I solved It in iOS using the github repository equals to the Tangem App Pod File.

But in Android I can´t found the way to use your actual version, how I can use
tangemCardSdk = "release-app_5.4-315"
in the build.gradle of Flutter Tangem SDK?.

The actual Flutter Tangem SDK build.gradle code

`group 'com.tangem.tangem_sdk'
version '1.0-SNAPSHOT'

buildscript {
ext.kotlin_version = '1.8.0'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:7.1.2'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

}

allprojects {
repositories {
google()
mavenCentral()
maven {url 'https://jitpack.io'}
}
}

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
compileSdkVersion 33

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

defaultConfig {
    minSdkVersion 21
}

}

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

implementation "com.github.tangem.tangem-sdk-android:android:3.8.2"
implementation "com.github.tangem.tangem-sdk-android:core:3.8.2"

implementation 'com.squareup.moshi:moshi:1.12.0'
implementation "com.squareup.moshi:moshi-kotlin:1.12.0"
kapt("com.squareup.moshi:moshi-kotlin-codegen:1.12.0")

implementation 'androidx.appcompat:appcompat:1.6.1'
implementation 'androidx.core:core-ktx:1.10.1'

}
`

Here you can see the issue:

tangem/tangem-sdk-flutter#20

Version

3.6.2

Issue:

Attempt to remove support for legacy support libraries causes a warning and performance issue:

The following legacy support libraries are detected:
app -> com.github.tangem.tangem-sdk-android:android:3.6.2 -> at.favre.lib:armadillo:0.9.0 -> com.android.support:support-annotations:28.0.0

Steps to reproduce:

• Apply the latest dependency com.github.tangem.tangem-sdk-android:android:3.6.2
• In the gradle.properties file apply android.enableJetifier=false

Suggestions:

Update the legacy dependency at.favre.lib:armadillo:0.9.0 to at.favre.lib:armadillo:1.0.0+

Thanks.

Using:

implementation "com.github.tangem.tangem-sdk-android:core:3.8.2"
implementation "com.github.tangem.tangem-sdk-android:android:3.8.2"

When I try to get something signed using TangemSdk.sign , after successfully signing and getting the CompletionResult.Success , also the CompletionResult.Failure is invoked unexpectedly.

To be clear, the the Success part works OK and has the correct signature. So things seem to work fine, until the Failure is also triggered. It doesn't cause problems when the failure is ignored, but if a failure message is displayed or some code is run when Tangem signing fails, it breaks the proper operation.

The code I receive in the Failure TangemSdkError is 50002 .
Perhaps this has something to do with cards setup with the older Tangem app. Perhaps not.

Could you please check?

Thanks for fixing #225 but now it seems sources for tangem-sdk-android/android is not included in version 3.7.1. this is necessary for other platforms SDK's like react-native

Hi There,

I am unable to download the lib from android studio always getting the above error. added all the steps specified in the below document still facing the issue. Can you please help me to fix this asap

Document Link : https://developers.tangem.com/getting-started/android

Description

For the TlvTag enum there are InteractionMode and WriteFileMode which both have a value of 0x23. I just want to reassure if that's correct.
There is also a duplicate CardIdManufacturerSignature which is not really an urgent issue but may be a nit to fix with next push.

I've got a Nokia 8.1 running Android 11. When trying to scan my STELLAR-card the error 30001 is shown.

I verified that the card works by scanning with another phone (wileyfox, android 7).

Initially the error occured in the official Tangem App. I tried to verify if it's a problem with that app and built a dummy react-native app using https://github.com/XRPL-Labs/tangem-sdk-react-native (which is the one dowloaded through npm i tangem-sdk-react-native). But that showed the exact same dialog and also failed with error 30001.

Please add documentation of how to achieve equivalent of https://docs.ethers.io/v5/api/signer/#Signer-signMessage

Version

3.7.0

Issue:

Can't find dependecy for the 'android' path.

dependencies {
    implementation "com.github.tangem.tangem-sdk-android:core: 3.7.0" // Ok
    implementation "com.github.tangem.tangem-sdk-android:android: 3.7.0" // Don't exist
}

I'm using the Android SDK in my app, with a card that has created a wallet through the Tangem Android app.
When I scan the card successfully, I get 2 CardWallet's. Since my app is based on Ethereum, I'm looking at the one with curve secp256k1
My public key for this wallet is :
0x03a2eeec0b16a6287903f5b426c06ced04b03c1305c50d9e40625cb5f7f3748e4d
The corresponding address would be:
0x85ebce013Acd634eaA2cFD2C6AF88B9c1dEF0679

But this is not the address I'm seeing in the Tangem App under Ethereum Mainnet. The one in the Tangem app is:
0x5623bEda.....f071395b

In settings of my Card : isHDWalletAllowed=true
cardWallet.derivedKeys is empty

How can I get the public key that corresponds to the address seen in the Tangem app, so my app and the Tangem app would use the same address?

I tried deriving more public keys from wallet.extendedPublicKey, but not hit any matches (what is the derivation path)? Do you have any working code for it?

Any help appreciated, since I'm stuck on this problem for 2 days.

I am using

implementation "com.github.tangem.tangem-sdk-android:core:3.6.2"
implementation "com.github.tangem.tangem-sdk-android:android:3.6.2"

Thanks
