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 23
buildToolsVersion "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'


}

        android:layout_height="wrap_content"
        android:text="Check this out"

        />

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,请尝试以下操作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.
