畢加索和Firebase存儲

我試圖使用Firebase Storage和Picasso在ImageView中加載圖像，但它在logcat中顯示空指針異常。當我錯了please.Below是我MainActiviy.class畢加索和Firebase存儲

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); 


    } 
}

然後，這是我的錯誤logcat中。

當下面的語句活動對象的初始化過程中執行，mStorage尚未初始化，併爲空：

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

變化storageRef聲明刪除初始化：

StorageReference storageRef;

然後在onCreate()中初始化它：

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

由於它的工作，但爲什麼火力地堡的未加載圖像的URL，甚至當我在瀏覽器中複製它不加載爲什麼@qbix –

@LutaayaHuzaifah：你需要使用'getDownloadUrl（）'而不是'getBucket（）'。看到這個例子代碼的答案：http://stackoverflow.com/a/37701878/4815718 –

謝謝@qbix，我已經這樣做，但應用程序加載時，什麼也沒有顯示，它不會崩潰，檢查我的logcat，我已經更新它。我看到它的說法谷歌播放服務已過時，但我剛剛更新它們。代碼中是否有錯誤？ –
