推荐答案

您将获得的.keystore 或 .jks 文件生成的同时使用，你必须为应用程序创建指纹这是后来用于生成的谷歌开发者控制台。

You will get .keystore or .jks file while generating signed APK.In fact using that you have to create the finger print for your application which is later used to generate Android Key in Google developer console.

现在你必须做的就是使用命令生成的SHA-1证书指纹

Now what you have to do is use the command to generate the SHA-1 certificate fingerprint

 keytool -list -v -keystore "path_to_jks_file.jks" -alias androiddebugkey -storepass android -keypass android

在 path_to_jks_file.jks 你应该给你生成时签署了您的 .jks 文件的路径APK。

In that path_to_jks_file.jks you should give the path of your .jks file that you got when generating signed APK.

，并从谷歌开发者控制台的Andr​​oid键，然后在清单中添加它

And get your android key from google developer console then add it in manifest

和记得签约配置添加到您的的build.gradle

And remember to add the signing configuration to your build.gradle

signingConfigs {
        release {
            storeFile file("myreleasekey.jks")
            storePassword "password"
            keyAlias "MyReleaseKey"
            keyPassword "password"
        }
    }
