uri

问题 I'm trying to make an application with sharing of children that are inside the "raw" folder of the application, but I'm not getting it. The file is shared but does not have an .mp3 extension. I was not able to hear Windows Media Player, but I put a .mp3 extension manually. Does anybody have any idea how I do it to get .mp3 extension automatically? Transform / rename a URI into mp3 file. The name of the song comes as it is registered in the file, I believe that if it was possible to rename

问题 I'm using Intent.ACTION_GET_CONTENT to select a file. In the method onActivityResult I get the Uri: Uri selectedfile = data.getData(); How can I use the Uri object selectedfile to open a SQLite database? This does not work: SQLiteDatabase database = SQLiteDatabase.openDatabase(selectedfile.getPath(), null, SQLiteDatabase.OPEN_READONLY); 回答1: You should not try to open a SQLiteDatabase from a Uri. SQLiteDatabase is designed to work directly with filesystem: it needs to lock and unlock the

问题 I want to connect via UPD to my sip server, I have the username, the ip address of the server (domain) and the port (for example 9990).

问题 I'm trying to send an image URI from a Website canvas to application with Javascript. In the Website I'm using the following function that relies on the html2canvas plugin: $("div.imagecapture").click(function() { html2canvas(document.getElementById('paper_trolley_center'), { onrendered: function(canvas) { var strDataURI = canvas.toDataURL("image/jpeg"); console.log('La imagen: '+strDataURI); jsNativeInterface.metodoDemo1(strDataURI); } }); }); The console.log outputs the URI, but the

问题 There are Android and iOS applications, I have dynamical URI and I need to redirect Android and iOS users directly to mobile application via nginx, only if they use this link. But I don't understand how to handle it without "logical and" or "inner if". As I understand I have to solve two conditions: if ($http_user_agent ~* '(iphone|ipod|nokia|аndroid)' ) { rewrite ^ mobile_application://$host$request_id last; } and: set $my_uri sign-up?invitation=$key #this key is dynamical if ($request_id =

问题 Java's URI class defines opaque URIs as follows (emphasis mine). A URI is opaque if, and only if, it is absolute and its scheme-specific part does not begin with a slash character ('/'). An opaque URI has a scheme, a scheme-specific part, and possibly a fragment; all other components are undefined . True to the documentation, an opaque URI returns null for a query param. URI uri = URI.create("stackoverflow:foo?key=value#frag"); uri.isOpaque() == true uri.getScheme() == stackoverflow uri
