java– 谷歌登录签名apk无法正常工作

好吧一切正常,直到我生成签名的apk.我在谷歌开发者页面上讲述了整个过程

1.我生成了带有keyhash和包名称的Google-services.Json文件
2.包括所有类级别和应用程序级别的依赖关系

// top-level build file where you can add configuration options common to all sub-projects/modules. buildscript {repositorIEs {    jcenter()}dependencIEs {    classpath 'com.androID.tools.build:gradle:1.3.0'    classpath 'com.Google.gms:Google-services:2.0.0-Alpha6'    // NOTE: Do not place your application dependencIEs here; they belong    // in the indivIDual module build.gradle files}} allprojects {  repositorIEs {     jcenter()   }  }

应用程序gradle文件

apply plugin: 'com.androID.application'apply plugin: 'com.Google.gms.Google-services'androID {compileSdkVersion 23buildToolsversion "23.0.0"defaultConfig {    applicationID "com.example.skmishra.finalGooglesignin"    minSdkVersion 14    targetSdkVersion 23    versionCode 1    versionname "1.0"}buildTypes {    release {        MinifyEnabled false        proguardfiles getDefaultProguardfile('proguard-androID.txt'),          'proguard-rules.pro'    }   }} dependencIEs {compile filetree(dir: 'libs', include: ['*.jar'])compile 'com.androID.support:appcompat-v7:23.1.1'compile 'com.Google.androID.gms:play-services:8.3.0'}

解决方法:

据我了解,您已在开发人员控制台中提供了调试SHA1,
然后你签了apk并更改了SHA1.
如果是这种情况,请尝试以下 *** 作obtain the release SHA1 from the keystore并将旧的SHA替换为.

1.打开终端并将目录更改为JDK bin目录.在路径中包含已安装的JDK版本,对我来说是 – jdk1.8.0_101(输入javac -version来获取Java版本)：

苹果电脑

    cd /library/Java/JavaVirtualMachines/<your_JDK_version>.jdk/Contents/Home/bin

视窗

    cd C:\Program files\Java\your_JDK_version\bin 

2.使用keytool获取版本SHA1：

    keytool -List -v -keystore <keystore_name> -alias <alias_name>

3.转到project’s credentials page并将SHA1替换为密钥库的版本SHA1.
