毕加索和Firebase存储

我试图使用Firebase Storage和Picasso在ImageView中加载图像，但它在logcat中显示空指针异常。当我错了please.Below是我MainActiviy.class毕加索和Firebase存储

package oerrride.we.huzykamz.imageretrieval; 

import android.net.Uri; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.widget.ImageView; 

import com.google.android.gms.tasks.OnSuccessListener; 
import com.google.firebase.storage.FirebaseStorage; 
import com.google.firebase.storage.StorageReference; 
import com.squareup.picasso.Picasso; 

import oerrride.we.huzykamz.testingappfirebase.R; 

public class MainActivity extends AppCompatActivity { 
    public FirebaseStorage mStorage; 
    ImageView img; 

    StorageReference storageRef = mStorage.getReferenceFromUrl("gs://askdoctor-546bf.appspot.com"); 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mStorage= FirebaseStorage.getInstance(); 

     img =(ImageView) findViewById(R.id.img); 
     StorageReference spaceRef = storageRef.child("askdoctor/namasuba.jpg"); 
     String url = spaceRef.getBucket(); 


     System.out.println("Here is the print of url : "+url); 
     Picasso.with(MainActivity.this).load(url) 
       .error(R.mipmap.ic_launcher). 
       resize(50, 50) 
       .placeholder(R.mipmap.ic_launcher).into(img); 


    } 
}

然后，这是我的错误logcat中。

当下面的语句活动对象的初始化过程中执行，mStorage尚未初始化，并为空：

StorageReference storageRef = mStorage.getReferenceFromUrl("gs://askdoctor-546bf.appspot.com");

变化storageRef声明删除初始化：

StorageReference storageRef;

然后在onCreate()中初始化它：

mStorage= FirebaseStorage.getInstance(); 
mStorageRef = mStorage.getReferenceFromUrl("gs://askdoctor-546bf.appspot.com");

由于它的工作，但为什么火力地堡的未加载图像的URL，甚至当我在浏览器中复制它不加载为什么@qbix –

@LutaayaHuzaifah：你需要使用'getDownloadUrl（）'而不是'getBucket（）'。看到这个例子代码的答案：http://stackoverflow.com/a/37701878/4815718 –

谢谢@qbix，我已经这样做，但应用程序加载时，什么也没有显示，它不会崩溃，检查我的logcat，我已经更新它。我看到它的说法谷歌播放服务已过时，但我刚刚更新它们。代码中是否有错误？ –
