Firestore Android保存失败-无法访问Firestore后端

google-cloud-firestore kotlin firebase android

有人看到在Android上用Firestore保存文档有问题吗?好像发生在 'com.google.firebase:firebase-firestore:17.0.x'

尝试这样做一个简单的保存:

val db = FirebaseFirestore.getInstance()

db.collection("users").document("user1").set(user)
    .addOnSuccessListener {
        Log.d(TAG, "Save OK")
    }
    .addOnFailureListener {
        Log.e(TAG, "Save Failed")
    }

但这两个倾听者都没有被召唤。我在日志中看到的唯一错误是:

Firestore后端。

com.google.firebase:firebase-firestore:16.0.0 似乎解决了问题。

弱点生成.gradle-

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'kotlin-kapt'

def dbflow_version = "4.2.4"

android {
    compileSdkVersion 28
    buildToolsVersion '28'
    defaultConfig {
        applicationId "ce.test"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {
            java.srcDirs = ['src/main/java', 'src/main/java/ce.test/models']
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    implementation 'com.android.support:preference-v7:28.0.0-alpha3'

如果设备无法访问Firestore后端,则不会调用成功侦听器和失败侦听器。成功/失败侦听器仅在数据提交给Firebase服务器或被Firebase服务器拒绝后才会被调用。

这不是强制性的,但我建议您使用Firestore的最新版本。为此,请更改以下代码行:

 implementation 'com.google.firebase:firebase-firestore:17.0.1'

到

implementation 'com.google.firebase:firebase-firestore:17.0.4'

相反,您应该在文件末尾添加以下代码行:

apply plugin: 'com.google.gms.google-services'

也请不要忘记生成.gradle(项目)文件,以下代码行:

classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.2'
