将自己的应用加入系统的打开方式和分享列表中

1、分享列表中显示自己的应用
在用系统默认的分享功能都会调用系统中可分享的应用的一个列表，但是如何使自己的应用加入这个列表呢？首先需要配置androidmanifest.xml,在分享页面的activity加入下边的filter
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
这样就可以过滤分享文本的时候自己的应用出现在列表中。
接受内容，在对应的activity中intent中获取相关的数据
title = intent.getStringExtra(SHARE_IMG_TITLE);
(Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM)
具体的mimeType类型有
{".3gp", "video/3gpp"},
{".apk", "application/vnd.android.package-archive"},
{".asf", "video/x-ms-asf"},
{".avi", "video/x-msvideo"},

2、打开方式中增加自己的应用
安卓中的文件打开一般都会让选择打开方式，看到所有文件的打开方式中都有QQ，而QQ是直接发送给了好友，其实也算是一种分享，具体方法和分享类似只是filter名字是view
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
