Firebase自定義應用程序設置

customApp= new FirebaseApp(getApplicationContext(),"My News",<to be filled>); 
    storage = FirebaseStorage.getInstance(customApp);

我是firebase的新用戶，自定義應用程序的確切用途是什麼。Firebase自定義應用程序設置

我想創建一個自定義應用程序，使用Firebase將大文件上傳到谷歌雲存儲。這是爲我推薦的自定義應用程序嗎？

如果你是新的火力地堡，機會是你不需要定製FirebaseApp。相反，只需使用FirebaseStorage.getInstance().getReference()，如Firebase Storage documentation所示。

不需要使用customApp;

簡單，我們可以使用

storage = FirebaseStorage.getInstance("gs://<Google cloud storage bucket name>");

如果我們想要存儲的引用然後

mStorageRef = storage.getReferenceFromUrl("gs://<Google cloud storage bucket name>");

@Override 
public void onCreate() { 
    super.onCreate(); 
    FirebaseOptions options = new FirebaseOptions.Builder() 
      .setApiKey("AI...3LnY") 
      .setStorageBucket("gs://f...t") 
      .setApplicationId("1:356....:android:f......232") 
      .build(); 
    customApp = FirebaseApp.initializeApp(getApplicationContext(),options,"MyApp"); 
    //storage 
    storage = FirebaseStorage.getInstance(customApp);`enter code here`

}

我們可以使用上面代碼中說明的firebase customApp –

偉大的答案弗蘭克van puffelen先生。它的工作對我來說（進口從谷歌Cloud Storage值。）

mStorageRef = FirebaseStorage.getInstance("gs://c......s").getReference();

從谷歌雲存儲的文件下載到使用火力本地設備。

final StorageReference downloadRef; 
     downloadRef = mStorageRef.getRoot().child(downloadPath); 

     try { 
      File output = new File(Environment.getExternalStorageDirectory() + File.separator + Config.MY_VIDEOS_PATH); 
      if (!output.exists()) { 
       output.mkdir(); 
      } 
      localFile = new File(output, downloadId); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 


     // Download and get total bytes 
     downloadRef.getFile(localFile) 
       .addOnProgressListener(new OnProgressListener<FileDownloadTask.TaskSnapshot>() { 
        @Override 
        public void onProgress(FileDownloadTask.TaskSnapshot taskSnapshot) { 
         showProgressNotification(title, "", 
           taskSnapshot.getBytesTransferred(), 
           taskSnapshot.getTotalByteCount()); 
        } 
       }) 
       .addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() { 
        @Override 
        public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) { 
         Log.d(TAG, "download:SUCCESS"); 
         // Send success broadcast with number of bytes downloaded 
         broadcastDownloadFinished(downloadPath, taskSnapshot.getTotalByteCount()); 
         showDownloadFinishedNotification(downloadPath, (int) taskSnapshot.getTotalByteCount()); 

         // Mark task completed 
         taskCompleted(); 
        } 
       }) 
       .addOnFailureListener(new OnFailureListener() { 
        @Override 
        public void onFailure(@NonNull Exception exception) { 
         Log.w(TAG, "download:FAILURE", exception); 
         Log.w(TAG, "download:FAILURE", exception.getCause()); 

         // Send failure broadcast 
         broadcastDownloadFinished(downloadPath, -1); 
         showDownloadFinishedNotification(downloadPath, -1); 

         // Mark task completed 
         taskCompleted(); 
        } 
       });
