打开方式显示自己的APP

先说一下格式，待会设置的mimeType格式：

统一格式：

• 视频：video/*
• 音频：audio/*
• 图片：image/*
• 全部：*/*

详细格式：

• rar：application/x-rar-compressed
• jpg：image/jpeg
• zip：application/zip
• pdf：application/pdf
• doc：application/msword
• docx：application/msword
• wps：application/msword
• xls：application/vnd.ms-excel
• et：application/vnd.ms-excel
• xlsx：application/vnd.ms-excel
• ppt：application/vnd.ms-powerpoint
• html：text/html
• htm：text/html
• txt：text/html
• mp3：audio/mpeg
• mp4：video/mp4
• 3gp：video/3gpp
• wav：audio/x-wav
• avi：video/x-msvideo
• flv：flv-application/octet-stream

……

1、举例：视频文件打开方式显示自己的APP：

<activity android:name="com.xaehu.livehd.MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <intent-filter tools:ignore="AppLinkUrlError">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="video/*" />
    </intent-filter>
</activity>

2、接收：

Intent intent = getIntent();
String action = intent.getAction();
if (Intent.ACTION_VIEW.equals(action)) {
    Uri uri = intent.getData();
    if(uri != null){
        //路径：
        //String url = uri.getPath();
        //真实路径：
        //String url = getRealFilePath(this,uri);
    }
}

附：获取真实路径方法：

public static String getRealFilePath( final Context context, final Uri uri ) {
    if ( null == uri ) {
        return null;
    }
    final String scheme = uri.getScheme();
    String data = null;
    if ( scheme == null ){
        data = uri.getPath();
    }
    else if ( ContentResolver.SCHEME_FILE.equals( scheme ) ) {
        data = uri.getPath();
    } else if ( ContentResolver.SCHEME_CONTENT.equals( scheme ) ) {
        Cursor cursor = context.getContentResolver().query( uri, new String[] { MediaStore.Images.ImageColumns.DATA }, null, null, null );
        if ( null != cursor ) {
            if ( cursor.moveToFirst() ) {
                int index = cursor.getColumnIndex( MediaStore.Images.ImageColumns.DATA );
                if ( index > -1 ) {
                    data = cursor.getString( index );
                }
            }
            cursor.close();
        }
    }
    return data;
}

完。
