谷歌地图Android的V2 - 空白屏幕空白、屏幕、地图、Android
我实现谷歌地图Android版。我创建了一个测试应用程序，并插入到该应用程序的所有的权限等，并应用完美地工作。
I am implementing google maps for android. I created a test application and inserted all the permissions etc in that application and the application worked flawlessly.
但是，当我试图复制相同的code到我的实际应用它显示我对Android activity.Although我在谷歌API控制台。
But when I try and copy the same code to my real application it shows me blank screen on the android activity.Although I've updated the package name in the google api console.
下面是我的测试项目清单如下：
Here's what my Test Project Manifest Looks Like :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mapstutorial"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<permission
android:name="com.example.mapstutorial.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
<uses-permission android:name="com.example.mapstutorial.permission.MAPS_RECEIVE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<uses-library android:name="com.google.android.maps" />
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="my api key"/>
<activity
android:name="com.example.mapstutorial.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
和这里就是我真正的项目清单如下：
and here's what my real project manifest looks like :
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.shop.shoppinglist"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" />
<permission android:name="com.shop.addtask.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<permission android:name="com.shop.shoppinglist.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="com.shop.addtask.permission.MAPS_RECEIVE"/>
<uses-permission android:name="com.shop.shoppinglist.permission.C2D_MESSAGE" />
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:allowBackup="true"
android:theme="@style/AppTheme" >
<uses-library android:name="com.google.android.maps"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>
<activity
android:name=".Login_Activity"
android:label="@string/title_activity_main"
android:theme="@style/Theme.Sherlock"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
我更新包的名称以 com.shop.addtask 在我的控制台指纹，但它仍然让我看到白色screen.What可能会导致这个问题？该 apikey 我用的是在这两个应用程序一样。但是，它适用于测试应用程序不在真正的应用程序。
I updated the package name to com.shop.addtask in my console fingerprint but still it shows me the white screen.What could cause the problem ? The apikey I've used is same in both of the applications. But it works on test application not on the real app.
在谷歌地图Android的V2控制台
在我使用中提到的控制台相同的API密钥。
I've created the api key using the fingerprint
I've switched on google maps android v2 in the console
I am using the same api key as mentioned in the console.
所以，这些事情是正确的，这个问题不能由其中一人引起的。
So these things are correct and the problem cannot be caused by one of them.
推荐答案
2可能的原因：
1 这部分：
<uses-library android:name="com.google.android.maps"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>
应该结束申请前右标记。
2 最有可能的，你有你的钥匙某种问题。尝试生成一个新的通过删除 debug.keystore 文件夹，然后运行项目。然后通过控制台重新注册。
2. Most likely you have some sort of problem with your key. Try to generate a new by deleting the debug.keystore folder and running a project. then register it again via the console.
您可以使用本指南我写来做到这一点：
you can use this guide I wrote to do just that:
谷歌地图API V2关键
更新：
选中此为第二个：
<permission android:name="com.shop.addtask.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
看起来您在此处设置的包是不是你的应用程序的软件包，应该是：
it looks that the package you set here is not the package of your application and should be:
<uses-permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE"/>
<permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
