当我尝试将图像上传到firebase存储android时调用addOnFileListener

Question

我是 Firebase 存储的新手。只是为了学习它，我正在尝试将图像从 ImageView 上传到 firebase 存储。我的应用程序有一个按钮。当我单击按钮时，图像（来自 drawable）会显示在 imageview 上，此外，单击按钮时图像应该上传到 firebase 存储。到目前为止，我已经在单击按钮时显示了图像，但我无法将其上传到 firebase 存储。addOnFileListener 被调用（我正在通过敬酒检查哪个被调用）这是我的我收到的主要 java 文件和错误。为了以防万一，我还将我的 Firebase 存储设置为公开。我需要进行哪些更改？

    }

    public void showToast(String s) {
        Toast.makeText(this,s,Toast.LENGTH_SHORT).show();
    }
}

这是我收到的错误

这是我的 Firebase 存储规则：

service firebase.storage {
  match /b/savephoto-a1cc3.appspot.com/o {
    allow read,write;
  }
}

这是我的 activity_main 布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.asad.save_photo.MainActivity">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/button"
        android:id="@+id/image" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Button"
        android:id="@+id/button"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

Answer 1

解决了。需要更新 google play 服务并将我的 firebase 存储规则更改为：

service firebase.storage {
  match /b/savephoto-a1cc3.appspot.com/o {
    match /{allPaths=**} {
        allow read, write;
      }
  }
}

Answer 2

它对我有用。 首先，您应该像这样检查规则：

service firebase.storage {
  match /b/fbstorage-fd9ef.appspot.com/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

其次，您需要通过链接检查和更新您的 Google Play 服务：（重要）

https://play.google.com/store/apps/details?id=com.google.android.gms&hl=en

然后重新运行应用程序。祝你好运！

对于我来说，我发现模拟器没有播放服务。所以我从 android studio 的 sdk Manager 安装它并创建一个新的模拟器。最后，它在那个模拟器上运行。希望它会有所帮助。
