1. 增加Intent-Filter，使得当前应用会出现在特定文件共享功能菜单里

以下示例代码表示任何类型的文件"共享"(Share via)菜单都会出现当前应用。

           <intent-filter>                <action android:name="android.intent.action.SEND" />                <category android:name="android.intent.category.DEFAULT" />                <data android:mimeType="*/*" />            </intent-filter>

支持的MIME类型：

常见类型：

{".3gp", "video/3gpp"},　　{".apk", "application/vnd.android.package-archive"},　　{".asf", "video/x-ms-asf"},　　{".avi", "video/x-msvideo"},　　{".bin", "application/octet-stream"},　　{".bmp", "image/bmp"},　　{".c", "text/plain"},　　{".class", "application/octet-stream"},　　{".conf", "text/plain"},　　{".cpp", "text/plain"},　　{".doc", "application/msword"},　　{".exe", "application/octet-stream"},　　{".gif", "image/gif"},　　{".gtar", "application/x-gtar"},　　{".gz", "application/x-gzip"},　　{".h", "text/plain"},　　{".htm", "text/html"},　　{".html", "text/html"},　　{".jar", "application/java-archive"},　　{".java", "text/plain"},　　{".jpeg", "image/jpeg"},　　{".jpg", "image/jpeg"},　　{".js", "application/x-javascript"},　　{".log", "text/plain"},　　{".m3u", "audio/x-mpegurl"},　　{".m4a", "audio/mp4a-latm"},　　{".m4b", "audio/mp4a-latm"},　　{".m4p", "audio/mp4a-latm"},　　{".m4u", "video/vnd.mpegurl"},　　{".m4v", "video/x-m4v"},　　{".mov", "video/quicktime"},　　{".mp2", "audio/x-mpeg"},　　{".mp3", "audio/x-mpeg"},　　{".mp4", "video/mp4"},　　{".mpc", "application/vnd.mpohun.certificate"},　　{".mpe", "video/mpeg"},　　{".mpeg", "video/mpeg"},　　{".mpg", "video/mpeg"},       {".mpg4", "video/mp4"},　　{".mpga", "audio/mpeg"},　　{".msg", "application/vnd.ms-outlook"},　　{".ogg", "audio/ogg"},　　{".pdf", "application/pdf"},　　{".png", "image/png"},　　{".pps", "application/vnd.ms-powerpoint"},　　{".ppt", "application/vnd.ms-powerpoint"},　　{".prop", "text/plain"},　　{".rar", "application/x-rar-compressed"},　　{".rc", "text/plain"},　　{".rmvb", "audio/x-pn-realaudio"},　　{".rtf", "application/rtf"},　　{".sh", "text/plain"},　　{".tar", "application/x-tar"},　　{".tgz", "application/x-compressed"},　　{".txt", "text/plain"},　　{".wav", "audio/x-wav"},　　{".wma", "audio/x-ms-wma"},　　{".wmv", "audio/x-ms-wmv"},　　{".wps", "application/vnd.ms-works"},　　//{".xml", "text/xml"},　　{".xml", "text/plain"},　　{".z", "application/x-compress"},　　{".zip", "application/zip"},　　{"", "*/*"}

如果需要匹配特定类型，特定文件，可以用正则表达式，这里给出<data>参考链接：

2.添加相应的处理代码

@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Intent intent = getIntent();Bundle extras = intent.getExtras();String action = intent.getAction();// 判断Intent是否是“分享”功能(Share Via)if (Intent.ACTION_SEND.equals(action)){if (extras.containsKey(Intent.EXTRA_STREAM)){try{// 获取资源路径UriUri uri = (Uri) extras.getParcelable(Intent.EXTRA_STREAM);Log.i(TAG, "uri:" + uri.toString());//解析Uri资源ContentResolver cr = getContentResolver();InputStream is = cr.openInputStream(uri);// Get binary bytes for encodebyte[] data = getBytesFromFile(is);return;}catch (Exception e){Log.e(this.getClass().getName(), e.toString());}}else if (extras.containsKey(Intent.EXTRA_TEXT)){return;}}
