问题描述

我开发一个Android应用程序与11的minSdkVersion和17 targetSdkVersion。 我设计这个应用服务多个屏幕大小。所以我把支持清单中file.I所有屏幕想这个应用程式，以支持所有的密度。

I am developing an android application with minSdkVersion of 11 and targetSdkVersion of 17. I am designing this apps for multiple screen sizes. So i put the support for all the screens in manifest file.I want this apps to support all density.

我的Manifest.xml code：

My Manifest.xml code:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.sample"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="17" />


    <supports-screens
                android:smallScreens="true"
            android:normalScreens="true"
            android:largeScreens= "true"
            android:xlargeScreens="true"
            android:anyDensity="true"/>

    <application
        android:debuggable="true"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:name="CommApp" >


        <activity
            android:name="com.example.android.sample.MainActivity"
            android:label="@string/app_name" 
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
          <activity android:name="HomePage"
              android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
               android:screenOrientation="portrait"></activity>

          <activity android:name="Registering"
              android:screenOrientation="portrait"
              ></activity>

         <activity android:name="ListviewActivity"
              android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
             android:screenOrientation="portrait"></activity>



    </application>

</manifest>

我已经创建的布局文件夹中所有的屏幕尺寸为RES /布局小，RES /布局正常，RES /布局大型，RES /布局XLARGE。 我想运行在屏幕尺寸720x1280的模拟器这个应用中，此设备我创建的所有布局文件的RES /布局XLARGE文件夹。 但在运行它显示了以下错误：

I have created layout folder for all screen sizes as res/layout-small, res/layout-normal, res/layout-large, res/layout-xlarge. I want to run this application in a emulator of screen size 720x1280, for this device I created all layout files in res/layout-xlarge folder. But while running it shows the following error:

Invalid attribute value syntax for android:largescreens: = "true"
            android:xlargeScreens="true"
            android:anyDensity="true"/

我不知道什么是错的？谁能告诉我的解决方案。 先谢谢了。

I do not know what is the wrong? Can anyone please tell me the solution. Thanks in advance.

推荐答案

我有同样的错误与我的属性的格式是这样的：

I had the same error with my attributes formatted like this:

  <supports-screens android:smallScreens            = "false"
                    android:normalScreens           = "false"
                    android:largeScreens            = "false"
                    android:xlargeScreens           = "true"
                    android:requiresSmallestWidthDp = "720" />

错误：

update-manifest:
     [exec] Invalid attribute name: android:smallscreens            

删除等号两旁的空格符号固定它。

Removing the whitespace around the equals sign fixed it.
