Open url in another application or in browser [Titanium]

I am writing a functionality that needs to open a URL either in the another app [if installed in my phone] or else, in the browser.
To open the URL in browser, I can use Titanium.Platefor.openURL();
To open the app I am creating the intent.
var intent = Titanium.Android.createIntent({
packageName : appUrl,
action : Titanium.Android.ACTION_SEND,
data : url
});
intent.addCategory(Titanium.Android.CATEGORY_BROWSABLE);
Titanium.Android.currentActivity.startActivity(intent);
I have stuck in below things:
How to pass the url to other app to open - I tried passing url using url : 'http://someurl' and data: 'http://someurl' - but didn't help. I got the error: No Activity found to handle Intent
How to find out whether the app is install or not? If yes - ask for the application to open, if no - open the url in browser.
Can anyone help?
Thanks in advance!

You can identify app is install or not using URL schema with Titanium.Platefor.openURL(); method in android. (if app is not installed it will return false).
and for ios there is one method for identify Titanium.Platform.canOpenURL().
and also you can passed something value to application for example if you open google map application with source and destination lat long in ios then call like this
var strUrl = "http://maps.google.com/maps?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude;
if (OS_IOS) {
strUrl = "comgooglemaps://?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude + "&directionsmode=driving";
if (Titanium.Platform.canOpenURL(strUrl)) {
Ti.Platform.openURL(strUrl);
} else {
strUrl = "http://maps.google.com/maps?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude;
Ti.Platform.openURL(strUrl);
}
} else {
var result = Ti.Platform.openURL(strUrl);
Ti.API.info('RESULT = ' + result);
}
one more example.. if you want opening whatsApp application with given message text.
var whatsappUrl = encodeURI('whatsapp://send?text=' + msgBody);
if (OS_IOS) {
if (Ti.Platform.canOpenURL(whatsappUrl)) {
Ti.Platform.openURL(whatsappUrl);
} else {
Ti.Platform.openURL("https://itunes.apple.com/ae/app/whatsapp-messenger/id310633997?mt=8");
}
} else {
var isSuccess = Ti.Platform.openURL(whatsappUrl);
if (!isSuccess) {
Ti.Platform.openURL("https://play.google.com/store/apps/details?id=com.whatsapp&hl=en");
}
}
Hop this is helps you.. :)
Thanks

How to remove file from list after successful upload?

This is my first question on StackOverflow so please bear with my noobness.
I am writing a Cordova app with Ionic Framework and I am trying to upload multiple files from the camera to a server while displaying the uploaded files in a list and showing the progress for each of them. But I can't seem to figure out how to delete the files from the display list after a successful upload. I am trying to use the ID of the File I get after I push it to the array, but those seem to be incorrect sometimes. E.g. the ID in the progress event is different than in the success event and therefore I am removing the wrong file from the list or sometimes no file.
$scope.choosePic = function() {
window.imagePicker.getPictures(
function(results) {
for (var i = 0; i < results.length; i++) {
console.log('Image URI: ' + results[i]);
onSuccess(results[i]);
}
}, function (error) {
console.log('Error: ' + error);
}
);
}
$scope.delete = function ( item ) {
$scope.items.splice($scope.items.indexOf(item), 1);
}
var onSuccess = function(FILE_URI) {
console.log(FILE_URI);
$scope.picData = FILE_URI;
var filename = $scope.makeid();
var length = $scope.items.push({name: filename, image: $scope.picData, progress:0 });
$scope.$apply();
send($scope.picData,filename,length);
};
var onFail = function(e) {
console.log("On fail " + e);
}
send = function(imagedata,filename,length) {
var options = new FileUploadOptions();
var url = window.localStorage['URL'];
options.fileKey="file";
options.chunkedMode = false;
options.mimeType="image/jpeg";
options.headers = {Connection: "close"};
var params = {};
params.APIKEY = window.localStorage['APIKEY'];
params.DEVICEID = device.uuid;
options.params = params;
var ft = new FileTransfer();
var ID = length -1;
ft.onprogress = function(progressEvent) {
if (progressEvent.lengthComputable) {
var perc = Math.floor(progressEvent.loaded / progressEvent.total * 100);
if(!(typeof $scope.items[ID] == 'undefined')){
$scope.items[ID].progress=perc;
$scope.$apply();
console.log($scope.items[ID].name + "Upload progress: " + perc);
}
} else {
}
};
function onUploadSuccess(r) {
//alert("ID = " + ID + " Code = " + r.responseCode + "Response = " + r.response + "Sent = " + r.bytesSent);
//alert($scope.items[ID].name);
console.log("ID = " + ID + " Code = " + r.responseCode + "Response = " + r.response + "Sent = " + r.bytesSent);
$scope.items.splice(ID, 1); // remove uploaded image from list
$scope.$apply();
}
function onUploadFail(error) {
alert("An error has occurred: Code = " + error.code);
//console.log("upload error source " + error.source);
// console.log("upload error target " + error.target);
}
options.fileName=filename+".jpg";
ft.upload(imagedata, encodeURI(url), onUploadSuccess, onUploadFail, options);
}
});
I know this code probably rather clumsy but this the first time I am working with AngularJS and Cordova and the likes of it. Thanks for your help in advance.

Gear SDK SAFileTransfer FILE_IO error

I'm trying to send file from Android host to Samsung Gear device using Samsung Mobile SDK no matter how had I try, always get FILE_IO error.
I was trying all available permissions (on both sides).
Could anyone send me any hint?
Android side:
String filename = "file:///storage/emulated/0/Download/TestRecipe2-25.zip";
if (mGuruAgentService != null) mGuruAgentService.sendFile(filename);
public int sendFile(String fileName) {
if (mFileTransfer == null)
registerForFileTransfer();
if (mFileTransfer != null) {
try {
Log.i(TAG, "Sending file " + fileName);
tx = mFileTransfer.send(mPeerAgent, fileName);
return tx;
} catch (Exception e)
{
Log.i(TAG, "Cannot send file" + e.getMessage());
}
}
return 0;
}
Tizen side:
function fileReceiveInt() {
var newFilePath = "downloads/file.zip";
var receivefilecallback =
{
onreceive: function(transferId, fileName)
{
console.log("Incoming file transfer request form the remote peer agent. transferId: " + transferId + " file name : " + fileName);
try {
gFileTransfer.receiveFile(transferId, newFilePath);
} catch(e) {
console.log("Error Exception, error name : " + e.name + ", error message : " + e.message);
}
},
onprogress: function(transferId, progress)
{
console.log("onprogress transferId: " + transferId + ", progress : " + progress);
},
oncomplete: function(transferId, localPath)
{
console.log("File transfer complete. transferId: " + transferId);
},
onerror: function(errorCode, transferId)
{
console.log("FileReceiveError transferId: " + transferId + " code : " + errorCode);
}
}
try {
console.log('setting recieve interface');
gFileTransfer = SAAgent.getSAFileTransfer();
gFileTransfer.setFileReceiveListener(receivefilecallback);
} catch (err) {
console.log('getSAFileTransfer exception <' + err.name + '> : ' + err.message);
}
}
I will always get onError in tizen with FILE_IO error :(
I was testing gFileTransfer.receiveFile(transferId, ""); for default path, and File:///opt/usr/media/Downloads...
My tizen privileges:
<tizen:privilege name="http://tizen.org/privilege/content.read"/>
<tizen:privilege name="http://developer.samsung.com/privilege/accessoryprotocol"/>
<tizen:privilege name="http://tizen.org/privilege/content.write"/>
<tizen:privilege name="http://tizen.org/privilege/filesystem.read"/>
<tizen:privilege name="http://tizen.org/privilege/filesystem.write"/>
<tizen:privilege name="http://tizen.org/privilege/unlimitedstorage"/>
Thanks in advance for any help.

Change both filepaths and it should work.
Change Android's side to:
String filename = Environment.getExternalStorageDirectory() + "/Download/TestRecipe2-25.zip";
Change Tizen's side to:
var newFilePath = "file:///opt/usr/media/Downloads/file.zip";

How to download and save a file using phonegap/cordova on Android

I am at my whit's end.
I will try to keep it brief.
Using Cordova/Phonegap 3.0 (and get the same results on 2.8.0).
Android version 4.0.4.
Code works on BlackBerry10 (Q10 and Z10).
On Android it errors with a JSON Error (no, I'm not parsing JSON, this seems to come out of cordova's bowels). I will paste the JSON.stringified error object at the end of this.
So, on to code then:
First a filesystem success function:
function onFSSuccess(fileSystem) {
if (fileSystem == null) {
window.alert("fileSystem is null");
}
var root = fileSystem.root;
root.getDirectory("com.app.id",{create:true},gotDir,onError);};
Then a function to handle success with directory retrieval:
function gotDir(d){
DATADIR = d;
doTheDl (d.fullPath + "/update.sql",fileTransfer);
};
Then the actual call to get the filesystem:
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFSSuccess, null);
Then a function to download the file:
function doTheDl (localPath,fileTransfer) {
try {
window.alert ("Downloading to '" + localPath + "'");
fileTransfer.download (
uri,
localPath,
function (entry) {
try {
$("#dbDownloadProgressContainer").text("File saved to " + entry.name + ". Applying script to database...");
dbInitObj.applyUpdateScript(entry);
}
catch (e) {
window.alert ( e);
}
},
function (err) {
window.alert ("ERROROR!!! - " + err);
var errCodeName = err.code;
switch (err.code) {
case FileTransferError.FILE_NOT_FOUND_ERR:
errCodeName ='FILE_NOT_FOUND_ERR';
break;
case FileTransferError.INVALID_URL_ERR:
errCodeName="INVALID_URL_ERR";
break;
case FileTransferError.CONNECTION_ERR:
errCodeName="CONNECTION_ERR";
break;
case FileTransferError.ABORT_ERR:
errCodeName="ABORT_ERR";
break;
default:
errCodeName = "UNKNOWN";
break;
}
window.alert ("Download failed: " + err.source + ", " + err.target + ", " + errCodeName);
},
true
);
}
catch (e) {
window.alert ( e);
}
}
Man, gotta love all these async callbacks...
Next we get to the heart of the matter, trying to READ the downloaded file:
//Bulk of applyUpdateScript script ommited, but eventually it gets here:
function readComplete (evt) {
$("#dbDownloadProgressContainer").text("Parsing script file...");
//Got this gem from here: http://beckism.com/2010/09/splitting-lines-javascript/
var lines = evt.target.result.match(/^.*([\n\r]+|$)/gm);
//var lineIndx = lines.length;
window.setTimeout(function () {
$("#dbDownloadProgressContainer").text("Processing " + lines.length + " statements");
},50);
};
try {
var fileReader = new FileReader();
fileReader.onloadend=readComplete;
fileReader.onerror=function (err) {
//var errStr = translateFileError (err);
window.alert ("FileReader.onerror: " +JSON.stringify (err));
};
fileReader.onloadstart=function (evt) {
window.alert ("FileReader.onloadstart - " + JSON.stringify (evt));
};
fileReader.onload=function (evt)
{
window.alert ("FileReader.onload - Called when the read has successfully completed.- " + JSON.stringify (evt));
};
fileReader.onprogress = function (evt)
{
window.alert ("FileReader.onprogress - " + JSON.stringify (evt));
}
fileReader.onabort = function (evt)
{
window.alert ("FileReader.onabort - " + JSON.stringify (evt));
}
function gotFile (fileEntry) {
window.alert ("Activating reader for file '" + fileEntry.fullPath + "'");
fileReader.readAsText(fileEntry);
};
function noFileFound (fileError) {
alert ("Can not access database update script: code " + translateFileError (fileError));
};
// window.alert ("scriptPath.name = " + scriptPath.name);
DATADIR.getFile (scriptPath.name,null,gotFile,noFileFound);
}
catch (e) {
window.alert (e);
}
NOW, when I hit the reading bits, I eventually get this from the 'onerror' event (rember this is the JSON.stringfied error object:
{
"type":"error",
"bubbles":false,
"cancelBubble":false,
"cancelable":false,
"lengthComputable":false,
"loaded":0,
"total":0,
"target":{
"_readyState":2,
"_error":{
"code":"JSON error"
},
"_result":null,
"_fileName":"file:///mnt/sdcard/com.app.id/update.sql",
"_realReader":{
"error":null,
"result":"",
"readyState":0
}
}
}
Please also note that 'com.app.id' is a place holder for the actual app ID - can't paste that for fear of sensitive names. I did try other folder names as well.
Other notable(?) items:
The download progress event seems to indicate that we are downloading precisely double the actual file size (wtf?)
Results are the same on android device and emulator
BlackBerry10 seems to work fine
Thanks in advance to any clever people....

OK.
This was the solution:
function gotFile (fileEntry) {
fileEntry.file (function (file) {
fileReader.readAsText(file);
});
};
So thanks a BAJILLION to this dude:
http://www.html5rocks.com/en/tutorials/file/filesystem/?ModPagespeed=noscript
In case you missed it, the magic is the call to the "file(...)" function on the fileEntry object.
Why it works on the BB10 WITHOUT it....aarrgggghhh

How android can parse mailto url containing Japanese or Chinese characters

i've tried to parse a mailto url which contains Japanese or Chinese characters by using MailTo.parse(url) but it return null.
it's ok with English characters. How do I resolve that?
There's my code and logcat:
try {
url = URLDecoder.decode(url,"UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d(TAG, "url: " + url);
MailTo mt = MailTo.parse(url);
Log.d(TAG, "body: " + mt.getBody());
Log.d(TAG, "subject: " + mt.getSubject());
07-12 12:50:34.861: D/Fbaku(9484): url: mailto:?subject=幕末の時代を生き抜け！&body=iPhoneとiPod Touch対応の風雲幕末史を一緒にやりませんか？
07-12 12:50:34.861: D/Fbaku(9484): subject: null
07-12 12:50:34.861: D/Fbaku(9484): body: null
Edit: sorry, my mailto url contains a link in body like this: https://stackoverflow.com/posts/17607307
So MailTo.parse(url).getBody() and MailTo.parse(url).getSubject() return NULL
How can i fix it?

try by using toString() method
so change
Log.d(TAG, "body: " + mt.getBody());
Log.d(TAG, "subject: " + mt.getSubject());
to
Log.d(TAG, "body: " + mt.getBody().toString());
Log.d(TAG, "subject: " + mt.getSubject().toString());
