Android截屏

本篇文章主要介绍了关于Android方面的截屏操作，下面是主要的代码，最近也思考一个问题，怎么实现一个截屏后，把图片发送至一个服务器端呢，正在思考中希望有哪位有识之士给解答，有源码的更好，谢谢了！！

Android截屏代码如下：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="your.record.namespace"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk android:minSdkVersion="15" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>    <application        android:icon="@drawable/ic_launcher"        android:label="@string/app_name" >        <activity            android:name=".Record_GifActivity"            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>
