Android Studio 2.1.2与Firebase不工作 [英] Android Studio 2.1.2 with Firebase NOT WORKING

问题描述

每当我尝试启动Firebase时，总会有这些错误。

  W / GooglePlayServicesUtil：Google Play服务已过时。需要11020000，但找到8489470 
 W / FA：服务连接失败：ConnectionResult {statusCode = SERVICE_VERSION_UPDATE_REQUIRED，resolution = null，message = null} 
 E / FA：丢弃数据。 E / FA：无法获取应用程序实例ID 
 E / FA：无法将当前屏幕发送至服务
 E / FA：丢弃数据。无法将事件发送到服务
  

我得到的是与Google Play服务相关的内容，但我无法弄清楚如何解决这个问题，我正在运行Android Studio 2.1.2，并且SDK中没有针对Google Play服务的更新

编辑：我的应用程序Gradle一个模拟器）

  apply plugin：'com.android.application'
 
 android {
 compileSdkVersion 26 
 buildToolsVersion26.0.0
 
 defaultConfig {
 applicationIdcom.example.sc.voxcinemascamp
 minSdkVersion 15 
 targetSdkVersion 26 
 versionCode 1 
 versionName1.0
} 
 buildTypes {
 release {
 minifyEnabled false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt' ），'proguard-rules.pro'
} 
} 
} 
 
依赖关系{
编译fileTree（dir：'libs'，i nclude：['* .jar']）
 testCompile'junit：junit：4.12'
 compile'c​​om.android.support:appcompat-v7:26.0.0-alpha1'
 compile' com.google.firebase：firebase-core：11.0.2'
 
} 
 
应用插件：'com.google.gms.google-services'
  

解决方案

现在很清楚。您需要更新您的模拟器来安装Play Services 11，或者将您的Firebase依赖关系降级为与您的模拟器上安装的Google Play Services相匹配。

我宁愿建议更新模拟器，请勿降级由于模拟器而在您的应用中使用的Play服务。

whenever I try initiating firebase, there's always these errors

W/GooglePlayServicesUtil: Google Play services out of date.  Requires 11020000 but found 8489470
W/FA: Service connection failed: ConnectionResult{statusCode=SERVICE_VERSION_UPDATE_REQUIRED, resolution=null, message=null}
E/FA: Discarding data. Failed to send app launch
E/FA: Failed to get app instance id
E/FA: Failed to send current screen to service
E/FA: Discarding data. Failed to send event to service

I get it's something related to Google Play Services but I just cant figure out how to fix it, I'm running Android Studio 2.1.2 and there's no update for Google Play Services in the SDKs

EDIT: My App Gradle (I'm using an emulator)

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"

    defaultConfig {
        applicationId "com.example.sc.voxcinemascamp"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
    compile 'com.google.firebase:firebase-core:11.0.2'

}

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

解决方案

So, it's clear now. You need either update your emulator to get Play Services 11 installed on it, or downgrade your firebase dependency to match Google Play Services installed on your emulator.

I would rather suggest to update emulator, don't downgrade Play Services used in your app because of emulator.
