Question

我开发了一个与谷歌相关的小应用程序。
地图显示并且一切正常，但是当我在Play商店的个人帐户上上传相同的应用程序时，当我下载时，地图没有显示。 - 它与SH1指纹有关或与地图键有关吗？
请帮助我的朋友，因为我没有找到任何解决方案，但我在谷歌搜索中输入了正确的关键字。
提前感谢您

你必须使用ReleaeKey来谷歌地图发布应用程序，否则它将在地图上显示空白页面，因为你正在使用调试键，当你直接从PC调试应用程序时运行。所以使用Release键。

这样做：

           C:\Program Files\Java\jdk1.6.0_45\bin>keytool -genkey -v -keystore "C:\Users\cp
 01\.android\releasekey.ketstore" -alias release_alias -keyalg RSA -keysize 2048
-validity 10000
 Enter keystore password:

[Unknown]:

[Unknown]:
   What is the name of your City or Locality?

What is the name of your State or Province?
[Unknown]:
What is the two-letter country code for this unit?
[Unknown]:
Is CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown correct?
[no]:  yes

 a validity of 10,000 days
    for: CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknow

  Enter key password for <release_alias>
    (RETURN if same as keystore password):

     Signature algorithm name: SHA1withRSA
     Version: 3

这是制作发布密钥库和生成SHA1 fingreprint的完整过程，现在将此SHA1代码添加到Google API控制台上的注册APP。
