Question

我有一个Android应用程序，我想从Azure下载blob存储。我有一个连接字符串，但当我尝试解析它，我的应用程序给我错误和我的应用程序崩溃。我怎么能解决这个问题？

解析连接字符串的Activity：

package com.berkkarabacak.mspproje;

import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;
import com.microsoft.azure.storage.*;
import com.microsoft.azure.storage.blob.CloudBlobClient;
import com.microsoft.azure.storage.blob.CloudBlobContainer;
import com.microsoft.azure.storage.blob.ListBlobItem;

public class Checkactivity extends ActionBarActivity {
String tcnumara;
    public static final String ConnectionString =
            "DefaultEndpointsProtocol=http;"
                    + "AccountName=CENSORED;"
                    + "AccountKey=CENSORED";

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
            setContentView(R.layout.checkheartbeat);

        try
        {
            // Retrieve storage account from connection-string.
           CloudStorageAccount storageAccount = CloudStorageAccount.parse(ConnectionString);

        catch (Exception e)
        {
            // Output the stack trace.
           e.printStackTrace();
        }


    }

    }

logcat的：

查看您的gradle build file，您似乎正在使用Java存储库而不是Android存储库。如果您查看Android存储库的GitHub登录页面，应该有通过Gradle构建导入Android aar的说明。
