Android - 无法在 MapView 示例中找到 com.google.settings 的提供商信息

Android - Failed to find provider info for com.google.settings in MapView Example

提问by sarmad

I'm trying to implement the MapView example which is defined in Android Hello Views example but now I'm facing this error:

我正在尝试实现在 Android Hello Views 示例中定义的 MapView 示例，但现在我遇到了这个错误：

Failed to find provider info for com.google.settings

Any idea why this is happening?

知道为什么会这样吗？

The MapView example doesn't set API key by default. So you must set it. Here is step by step:

MapView 示例默认不设置 API 密钥。所以你必须设置它。这是一步一步：

1. Get MD5 from your system

   %JAVA_HOME%\bin\keytool.exe -list -alias androiddebugkey -keystore "%userprofile%\.android\debug.keystore" -storepass android -keypass android
   

2. Get API key by pasting the generated MD5 to this page:
   http://code.google.com/android/maps-api-signup.html

3. Paste the generated API key to {your_project_root}/res/layout/map.xml

   <com.google.android.maps.MapView
       android:id="@+id/myMapView"
       android:layout_width="fill_parent" 
       android:layout_height="fill_parent"
       android:enabled="true"
       android:clickable="true"
       android:apiKey="paste_generated_api_key_here"
   />
   

4. In AndroidManifest.xml, make sure that you have the folowing tag into your applicationtag:

   <uses-library android:name="com.google.android.maps" />
   

   and also the folowing tag into your manifesttag:

   <uses-permission android:name="android.permission.INTERNET" />
   

5. Refresh your project and run

1. 从您的系统中获取 MD5

   %JAVA_HOME%\bin\keytool.exe -list -alias androiddebugkey -keystore "%userprofile%\.android\debug.keystore" -storepass android -keypass android
   

2. 通过将生成的 MD5 粘贴到此页面来获取 API 密钥：http:
   //code.google.com/android/maps-api-signup.html

3. 将生成的 API 密钥粘贴到{your_project_root}/res/layout/map.xml

   <com.google.android.maps.MapView
       android:id="@+id/myMapView"
       android:layout_width="fill_parent" 
       android:layout_height="fill_parent"
       android:enabled="true"
       android:clickable="true"
       android:apiKey="paste_generated_api_key_here"
   />
   

4. 在AndroidManifest.xml 中，确保您的标签中有以下application标签：

   <uses-library android:name="com.google.android.maps" />
   

   以及以下标签到您的manifest标签中：

   <uses-permission android:name="android.permission.INTERNET" />
   

5. 刷新您的项目并运行

Note:

笔记：

• The path of keytool.exe, debug.keystore and map.xml may differ on your system.
• If you publish your app, be sure to register another API key.
• If you don't set API key properly, your app will fail on phone and the error message probably is "... has stopped unexpectedly. Please try again. - Force close"

• keytool.exe、debug.keystore 和 map.xml 的路径可能因您的系统而异。
• 如果您发布应用程序，请务必注册另一个 API 密钥。
• 如果您没有正确设置 API 密钥，您的应用程序将在手机上失败，并且错误消息可能是“ ...已意外停止。请重试。-强制关闭”

If you've made sure you have INTERNETpermission, and have correctly generated API key, and have put it in android:apiKey, and the same error still happens, here's one more thing to check: is your application signed with the same certificate that you used for Maps API key?

如果您已确定您拥有INTERNET权限，并正确生成了 API 密钥并将其放入 中android:apiKey，但仍然发生同样的错误，那么还有一件事需要检查：您的应用程序是否使用与地图相同的证书进行签名API 密钥？

Android build tools use different certificates for debug builds and for release builds. If you've generated MD5 checksum and API key for release certificate (the one that you use in "Export Android Application" wizard to generate .apk), it won't work in debug builds--and vice versa.

Android 构建工具使用不同的证书进行调试构建和发布构建。如果您为发布证书生成了 MD5 校验和和 API 密钥（您在“导出 Android 应用程序”向导中用于生成 .apk 的那个），它在调试版本中将不起作用，反之亦然。

You can find out where your debug keystore is located in Eclipse's Preferences > Android > Build page. You can generate MD5 checksum and API key for it the same way as for your release certificate. Default password for debug keystore is "android".

您可以在 Eclipse 的 Preferences > Android > Build 页面中找到调试密钥库的位置。您可以按照与发布证书相同的方式为其生成 MD5 校验和和 API 密钥。调试密钥库的默认密码是“android”。

Here's official docs about debug keystore

这是关于调试密钥库的官方文档

One more thing to check:

还有一件事要检查：

I just had this problem (or rather, my problem was that the map was not showing up). I had skimmed through the map view tutorial and pasted the "uses-permission" tag inside the application tag by mistake. It needs to be directly under the manifest tag, like this:

我刚刚遇到了这个问题（或者更确切地说，我的问题是地图没有显示出来）。我浏览了地图视图教程并错误地将“uses-permission”标签粘贴到了应用程序标签中。它需要直接在 manifest 标签下，像这样：

<?xml version="1.0" encoding="utf-8"?>
<manifest [...]>
  <uses-sdk [...] />
  <uses-permission android:name="android.permission.INTERNET" />

  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <uses-library android:name="com.google.android.maps" />
    [...]
  </application>
</manifest>

A very simple mistake, but it took me a while to find. Hopefully this helps someone else!

一个非常简单的错误，但我花了一段时间才找到。希望这对其他人有帮助！

I have only encountered this issue on the emulator and I have found that the only way around this error is to restart the emulator.

我只在模拟器上遇到过这个问题，我发现解决这个错误的唯一方法是重新启动模拟器。

Just review Hello, MapView :

只是回顾你好， MapView：

Make sure you have included into AndroidManifest.xml line for permissions:

确保您已将权限包含在 AndroidManifest.xml 行中：

<uses-permission android:name="android.permission.INTERNET" />

Also, have you got Google Map API Key?
Put it into MapView layout definition:

另外，你有Google Map API Key吗？
将其放入 MapView 布局定义中：

<com.google.android.maps.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:apiKey="Your Maps API Key"
/>
