i am trying to run a simple sample of getting product details in android, i am using java sample as guide. https://github.com/sphereio/sphere-hello-api/tree/master/java

  SphereClient sphere = SphereClient.create(
                new SphereClientConfig.Builder("xxxxxx", "xxxxxx", "xxxxxxxx", Locale.ENGLISH).build());

i am getting error:

io.sphere.client.SphereClientException: null: null

my build.gradle:

android { compileSdkVersion 22 buildToolsVersion '22.0.1'

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/ASL2.0'
}

defaultConfig {
    applicationId "com.spheretest"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

} dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.android.support:appcompat-v7:22.2.1' compile 'io.sphere:sphere-java-client:0.60.0' }

is there is any android sample i can test run for basic connection to Sphere?

there is an SDK for the commercetools platform that can be used in all JVM languages ("SPHERE JVM SDK": https://github.com/sphereio/sphere-jvm-sdk), but that requires Java 8 language features and is therefore not usable on Android because, well, Android is not a JVM.

The "old" SDK you're trying (and which is unfortunately still used in the Java Hello World example) is technically Android-compatible but I would not recommend using it as it's not maintained any more (https://github.com/commercetools/sphere-play-sdk).

As of today, Android clients are therefore built directly against the HTTP API using an Android built-in HTTP client etc.
The actual answer: You can find a working Android Sample with this Google Glass demo app (GitHub, MIT License): https://github.com/sphereio/google-glass-demo.

One caveat: the available OAuth authorization scopes of the SPHERE API are currently not powerful enough to build a fully native app including checkout directly against the commercetools (SPHERE) API. You will have to consider to either not doing checkout natively (i.e. webview), or (better) running a minimal server-side API shim that whitelists content for the public app and does the OAuth and knows secrets.

For a prototype / proof of concept like the Google Glass demo code above that isn't an issue nevertheless.

In the mean time, we've worked on a better support for mobile. For example, we created a Hello World for Android, that you can use as starting point for your mobile application: https://github.com/sphereio/commercetools-android-example

In the near future, we will continue to extend the support of mobile platforms.
