Question

我创建了一个带有maps.i的应用程序已经按照我从网上找到的每一步，我已经获得了密钥，应用程序在模拟器上运行良好，我可以看到地图。但是当我加载时singned apk到我的手机地图没有显示...... :( ..有什么想法吗？

Answer 1

这样做（假设keytool在你的路径中）：

类型

keytool -genkey -v -keystore my-release-key.keystore -alias release_alias -keyalg RSA -keysize 2048 -validity 10000

You should see the following prompts:
Enter keystore password:
Re-enter new password:
What is your first and last name?
  [Unknown]:  FirstName Surname
What is the name of your organizational unit?
  [Unknown]:  FirstName Surname
What is the name of your organization?
  [Unknown]:  FirstName Surname
What is the name of your City or Locality?
  [Unknown]:  YourTown
What is the name of your State or Province?
  [Unknown]:  YourTown
What is the two-letter country code for this unit?
  [Unknown]:  UK
Is CN=FirstName Surname, OU=FirstName Surname, O=FirstName Surname, L=YourTown, ST=YourTown, C=UK c
orrect?
  [no]:  yes

Generating 2,048 bit RSA key pair and self-signed certificate (SHA1withRSA) with
 a validity of 10,000 days
        for: CN=FirstName Surname, OU=FirstName Surname, O=FirstName Surname, L=YourTown, ST=Lond
on, C=UK
Enter key password for <release_alias>
        (RETURN if same as keystore password):
[Storing my-release-key.keystore]

此密钥库将位于您运行keytool命令的目录中，在我的情况下，它位于C：\ users \ FirstName

中

现在，要查看生成的MD5指纹，请键入：

keytool -list -alias release_alias -keystore c：\ users \ FirstName \ my-release-key.keystore

你会看到：

Enter keystore password:
release_alias, 08-Sep-2010, PrivateKeyEntry,
Certificate fingerprint (MD5): **:**:**:**:**:**:**:**:**:**:**:**:**:**:**:**

    (** is substituted for my private information, you should see hex values)

这是您从RELEASE密钥生成的新MD5，将其提交到Google API密钥页，您将返回：

Thank you for signing up for an Android Maps API key!
Your key is:
1234567891bcdefg1234567891bcdefg (or whatever yours is)
This key is good for all apps signed with your certificate whose fingerprint is:
**:**:**:**:**:**:**:**:**:**:**:**:**:**:**:**

将该密钥放入XML

Answer 2

您需要创建一个用于签署应用程序的密钥。对于你的这个键，你需要完成所有步骤，就像你使用自动生成的模拟器一样。

当您从eclipse中签署应用程序时，系统会询问您是否要创建密钥，创建密钥并记住存储密钥的位置。

然后转到C：\ Program Files \ Java \\ bin“并运行以下命令：从命令窗口

keytool.exe -list -alias androiddebugkey -keystore“C：\ YourCreatedKey”-storepass android -keypass android

复制MD5证书指纹并将您的Web浏览器导航到：http://code.google.com/android/maps-api-signup.html。按照页面上的说明完成申请并获取Google地图密钥。

在xml布局中使用mapView控件中的获取键。
