Question

在我的应用程序中使用谷歌地图版本2.当我在真实设备中通过eclipse运行应用程序意味着它显示地图。但是当我将应用程序导出为已签名的apk并在播放商店上传我的apk时。然后我下载从Play商店上传的apk文件，我在我的设备上运行但它只显示空白页面。我不知道问题是什么。任何知道。请帮助我解决这个问题。

Answer 1

您必须要求signed apk with SHA-1

第1步：

Now locate to jdk in C drive(Considering for windows and assigning C drive)

C:\Program Files\Java\jdk1.7.0\bin>keytool -list -v -keystore E:\A.keystore -alias A

So it will create SHA-1 finger print

第2步：

    Go to google api console.
    Generate new api key for android you have to used this SHA-1 and current playstore package name.
    Put Api key into your map.

我希望这对你来说已经足够了。如果查询发表评论。

Answer 2

因为当您签署应用程序时， SHA1指纹会发生变化。

所以当你使用已签名的应用程序时，请选择eclipse在签署过程中给你的SHA1并将其写入Google API CONSOLE中的允许应用程序

Answer 3

您需要使用密钥库创建地图密钥。

1）所以使用你的密钥库而不是debug.keystore生成sha-1。

2）转到google api console

3）为android生成新密钥

4）并使用您的包名称

传递这个新的SHA-1

5）将那个地图密钥放在你的代码中

Answer 4

这是因为在您导出应用程序的签名apk之后，其SHA1指纹会发生变化。

所以你需要这样做：

1) Generate sha-1 using your keystore rather debug.keystore.

2) Go to google api console

3) generate new key for android

4) and pass this new SHA-1 with your package name

5) put that map key in your code

并使用这个： https://code.google.com/apis/console/?pli=1

Answer 5

您正在使用调试密钥并导出apk。使用释放键。希望这可能有所帮助。

Google Map Android API v2 can't display map in play store application

Answer 6

要使用谷歌地图导出APK，您必须在导出时使用释放键而不是debug.keystore。

使用此方法为Google Maps API v2生成发布密钥。

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:

   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):
  Re-enter new password:

C:\Program Files\Java\jdk1.6.0_45\bin>keytool -list -v -alias release_alias -ke

Certificate fingerprints:
     MD5:  your md5 Fingure print
     SHA1: your SHA1 fingure print
     Signature algorithm name: SHA1withRSA

现在使用SHA1 fingure print在API控制台上注册应用程序
