The reason why you cant open your.BU file is because you dont. You get an annoying pop-up window that says, Windows cant open this file. My-file.BU Youre trying to open a.BU file youve received through an email attachment or a file on your hard drive, but your computer wont let you do it. Please share your ZIP Code to find a nearby Best Buy location , our Samsung representative, wants to know about you so they can assist you better.Here is how I defined my activity in my AndroidManifest.xml to get this to work. BU is not a popular format, which contains surveillance video in a proprietary Samsung format and can only be opened with Samsung products including devices and video software.A Samsung representative at Best Buy can set up a personal demonstration for your next galaxy device. The Definition of BU Files BU is a video format created with a Samsung DVR, for instance a CCTV (closed circuit television) recording system.Bu and.db2 files What I have done is downloaded Samsung Smartviewer 3.0, dowloaded a SML 3.0 player and the manual.MimeType can be set to */* to match any mime type.A universal software viewer saves you the hassle of installing many different software packages on your computer, without the limitation of being unable to view the files. One is a SML (SML Multimedia Presentation file) The other two are a. AVI file that won't play on anything. Our most recent information indicates that BU files are associated with only a single known file type, the Samsung CCTV Video File format, and can be viewed with the Samsung SmartViewer software package (developed by Samsung Electronics).I was handed four files that was produced/recorded/exported from a SAMSUNG SDE-4001.These strings require double escaping, so \. * at the beginning matches any squence of characters. Download File Magic now and try it for yourself.PathPattern is where you specify what extension you want to match (in this example.
I should note that this alone does not allow you to download this filetype in a browser, since this only registers with the file scheme. Kdb file in an app like Linda File Manager, my app shows up as an option. For a more detailed discussion of this issue and a workaround see hereFinally, according to the Android documentation, both host and scheme attributes are required for the pathPattern attribute to work, so just set that to the wildcard to match anything.Now, if you select a. This pattern will fail to match paths that contain a. * is not a greedy match like you would expect if this was a regular expression. One caveat with pathPattern is that. Samsung Bu File Viewer Code Is TheGmail will pass on the MIME type for the attachment unimpeded), the filter will match. But so long as the provider states your MIME type (E.g. This isn't perfect, but is the only way to match the behaviour of file managers like ES File Explorer, and it is limited to intents where the URI/file extension matches.I haven't included other schemes like "http" here, but they will probably work fine on all these filters.The odd scheme out is "content", for which the extension is not available to the filter. The path patterns do apply, for "file" scheme intents.The global mime type pattern match will match all types so long as the file extension matches. The parser code is the other relevant piece of the puzzle.The following filters get pretty close to sensible behaviour. The best, and given the strange logic, possibly the only real documentation is the source code.The intent filter implementation has logic that almost defies description. Attributes within a data element sometimes must go together and sometimes ignore grouping. Absence of a field sometimes is a wildcard and sometimes isn't. None of the pattern matching algorithms follow the same syntax or behaviour. And you will probably also choose to have a custom file extension. have my app handle files on filestorage that were generated by my app and have a particular extensionProbably the best way to go about this task is to specify a custom MIME Type for your attachments. have my app handle attachments shared by my app Most of the solutions posted on stackoverflow didn't work correctly for me. But getting it just right is hard. Converting quicken essentials for mac to windowsIt probably still works if these intent-filter blocks are merged but I haven't verified this. The Gmail app refused to list my app in the chooser if I added the android:host="*" attribute. If somebody gets the pathPattern to respond only to certain patterns I would be thrilled to see how. The pathPattern seems to be more or less ignored for attachments (when using android:scheme="content"). I figured this was a pretty rare event so it would acceptable.I could not find any way to launch my app via the file browser without adding to my intent-filter. I handled this in my activity by displaying a failed state if we could not parse the file. Caveats/GotchasI found that with my above solution, if I opened any file that was a binary type, it would automatically launch my app. A work around solution for email attachments Through testing I found the MIME-Types that Gmail, Outlook, and Samsung Email used and added those to my intent-filter. Thus, you cannot use the android:pathPattern like most have suggested. The ProblemA content URI does not necessarily have to contain the file's extension or name and it will be different between different applications that are providing the content/file.Here are some example content URIs from different email applications for the same email attachment:Gmail -> -> content://com.microsoft.office.outlook.fileprovider/outlookfile/data/data/com.microsoft.office.outlook/cache/file-download/file-2146063402/filename.customextentionSamsung Email App -> content://com.samsung.android.email.attachmentprovider/1/1/RAWAs can see they are all different and are not guaranteed to contain anything related to your actual file. This goes so far that even when I try to view/edit a contact in my contacts list Android asks me if I want to use my app to view the contact, and that is just one of many situations where this occurs, VERY VERY annoying.Eventually I found this google groups post with a similar question to which an actual Android framework engineer replied. I have an intent-filter with a "*/*" mimetype which is the only thing that seems to work and file-browsers now list my app as an option for opening files, however my app is now shown as an option for opening ANY KIND of file even though I've specified specific file extensions using the pathPattern tag. This was the best that I could do in my situation.I've been trying to get this to work for ages and have tried basicly all the suggested solutions and still cannot get Android to recognise specific file extensions. There is currently no elegant solution for associating your app with a specific extension type in Android. I would not recommend adding this to your intent-filter. Hope I saved someone some trouble.I've been struggling with this quite a bit for a custom file extension, myself. If you need a specific file-extension or a mime-type not known by Android however then you're out of luck.If I'm wrong about any of this please tell me, so far I've read every post and tried every proposed solution I could find but none have worked.I could write another page or two about how common these kinds of things seem to be in Android and how screwed up the developer experience is, but I'll save you my angry rantings ). If you are fortunate enough to only need files of a certain mime-type (say text, video or audio), you can use an intent-filter with a mime-type.
