java - 无法将图像上传到azure blob存储android

Question

我正在尝试将图像上传到 azure blob 存储。我正在使用 azure 的 java SDK。我已经引用了这些库。这是我的代码..

public void uploadImage(View view) {
    // Do something in response to button click
    try
     {
     String storageConnectionString = 
                RoleEnvironment.getConfigurationSettings().get("StorageConnectionString");
        CloudStorageAccount storageAccount =
                CloudStorageAccount.parse(storageConnectionString);

            // Create the blob client
            CloudBlobClient blobClient = storageAccount.createCloudBlobClient();

            // Retrieve reference to a previously created container
            CloudBlobContainer container = blobClient.getContainerReference("classifieds");

            // Create or overwrite the "myimage.jpg" blob with contents from a local file
            CloudBlockBlob blob = container.getBlockBlobReference("myimage.png");
             InputStream ims = getAssets().open("myimage.png");

            int len =ims.available();
            blob.upload(ims,(long)ims.available());
     }
     catch(Exception ex)
     {
         System.out.println(ex);
     }
}

这是我的错误日志

当您的代码作为云服务运行时，您只能使用RoleEnvironment类。由于您在 Android 应用程序中运行代码，因此您无法使用此类。

如果连接设置位于配置文件中，您可能需要使用其他方法来从该配置文件中读取。
