Commercetools Sphereio SphereClient爲空

Question

我想運行一個簡單的例子獲取Android產品詳細信息，我使用java示例作爲指南。 https://github.com/sphereio/sphere-hello-api/tree/master/java

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

我得到錯誤：

io.sphere.client.SphereClientException: null: null 

我的build.gradle：

的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' 
    } 
} 

} 依賴關係編譯fileTree（包括：['* .jar']，dir：'libs'） compile'c​​om.android.support:appcompat-v7:22.2.1' compile'io.sphere：sphere-java客戶端：0.60.0' }

是否有任何android示例我可以測試運行基本連接到球體？

Answer 1

沒有爲commercetools平臺的SDK可以在所有的JVM語言（ 「SPHERE JVM SDK」：https://github.com/sphereio/sphere-jvm-sdk）中使用，但需要的Java 8語言特性因此在Android上不可用，因爲Android不是JVM。

您嘗試使用的「舊」SDK（不幸的是，它仍然用於Java Hello World示例中）在技術上與Android兼容，但我不推薦使用它，因爲它不再被維護（https://github.com/commercetools/sphere-play-sdk）。

截至今天，Android的客戶端，因此直接內置反對使用HTTP API一個Android內置的HTTP客戶端等
實際的答案：你可以找到與此谷歌眼鏡演示應用工作的Android樣品（GitHub上，麻省理工學院執照）： https://github.com/sphereio/google-glass-demo。

需要注意的一點是：SPHERE API的可用OAuth授權範圍目前還不足以構建完全原生的應用程序，包括直接針對commercetools（SPHERE）API簽出。您將不得不考慮是否本地執行結賬（即webview），或者（更好地）運行最小化服務器端API Shim，將公共應用的內容列入白名單，並執行OAuth並知道祕密。

對於像上面的Google Glass演示代碼這樣的原型/驗證概念，這不是問題。

與此同時，我們也爲移動設備提供了更好的支持。 例如，我們創建了一個Hello World爲Android，你可以作爲出發點使用移動應用程序： https://github.com/sphereio/commercetools-android-example

在不久的將來，我們將繼續擴展的移動平臺的支持。
