Google Map Android API v2 无法在 Play 商店应用程序中显示地图 [英] Google Map Android API v2 can't display map in play store application

问题描述

我正在 Android 应用程序中使用 Google Map Android API v2.

I am working with the Google Map Android API v2 in an android application.

它与未签名的 apk 在不同设备上运行良好.但是当我签署了 apk 并将我的应用程序上传到 Play 商店时，下载的应用程序会显示一个白屏而不是地图.

It works fine with the unsigned apk on a different device. But when I have signed the apk and uploaded my application to the Play Store the downloaded application displays a white screen instead of the map.

推荐答案

您使用的是什么类型的密钥库?有两个键.Debug 和 release key.如果您使用调试密钥并上传到 android 市场，地图将显示为空白.在您签署 apk 时使用发布密钥.

What type of keystore you are using? there are two keys. Debug and release key. If you use debug key and uploaded in android market, map will look blank. Use release key when you signed your apk.

发布密钥程序

第 1 步:

例如，您的 apk 名称是 A，您正在为 A.apk 签名并创建密钥库，即 A.keystore 将在某个驱动器位置创建.让我们考虑在 E 驱动器中.

Say for example your apk name is A and you are signing and creating a keystore for A.apk ie A.keystore will be created in some drive location.Let's consider it in E drive.

第 2 步:

现在在C盘定位到jdk(考虑windows并分配C盘)

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

C:Program FilesJavajdk1.7.0in>keytool -list -v -keystore E:A.keystore -alias A

因此它将创建 SHA-1 指纹.

So it will create SHA-1 finger print.
