/ 29 января 2020

Я могу вставлять изображения в базу данных Firebase (облачное хранилище), но не могу получать изображения в режиме утилизации, я использую Glide вместо Picaso .. мой buid.gradle (app): 

 apply plugin: 'com.android.application'

  android {
 compileSdkVersion 28
 defaultConfig {
    applicationId "com.example.firestoreexample"
    minSdkVersion 21
    targetSdkVersion 28

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

     proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-       rules.pro'
    }
    }
