FirebaseStorage.getInstance（String url）..这个网址是什么？

时间：2018-10-17 05:04:28

标签： android firebase firebase-storage

在尝试访问Firebase存储时，应用程序崩溃。我正在调用另一个具有FirebaseStorage的所有方法和声明的Java类文件。每当我尝试访问此类文件时，都会在FirebaseStorage.getInstance（）方法中收到错误消息。 我想知道是否还有另一种方法可以明确提及该URL，以直接访问存储桶而不是访问应用程序的上下文。

PS：我从一个片段中打开此类，这可能是崩溃的原因。 有什么想法吗 ？ 谢谢：）

UploadImage.java 

public class UploadImage extends MainActivity{

private String path;
private StorageReference storageReference;

public UploadImage(String path){
    this.path = path;
    this.storageReference = FirebaseStorage.getInstance("gs://databasereal-bb774.appspot.com").getReference();
}

public void upload(){
    Uri file = Uri.fromFile(new File(path));
    StorageReference imageRef = storageReference.child("ParamedicImages");

    imageRef.putFile(file)
            .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    // Get a URL to the uploaded content
                    Log.d("Uupload","Uploaded");

                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    Log.e("failed upload", exception.toString());
                }
            });
}

}

例外

FirebaseStorage.getInstance（String url）..这个URL是什么？

您需要以URL方法传递Firebase存储桶中的FirebaseStorage.getInstance()

来自文档

FirebaseStorage getInstance (String url)

  • it返回FirebaseStorage，并使用默认FirebaseApp和自定义存储桶进行初始化。

参数

  • url gs：//指向您的Firebase存储桶的网址。

编辑

您需要更新您的firebase-storage依赖项

implementation 'com.google.firebase:firebase-storage:16.0.3'
