PhoneGap resolveLocalFileSystemURI

Question

I am trying to resolve this filesystem uri shown below:

/var/mobile/Applications/9483756B-8D2A-42C5-8CF7-8D76AAA8FF2C/Shift.app/iqedata/5977e2e9239649d5a7e3b8a54719679f/06e2b8896e51472789fcc27575631f94.jpg

Can any body tell me how to resolve this uri in PhoneGap and get the FileEntry by using the method showing below?

window.resolveLocalFileSystemURI(Url, resOnSuccess, resOnError);

I have tried to add "file://" or "//" before the uri but it doesn't work.

Thanks.

Solution

PhoneGap will not let you read files outside of the [APP HASH]/Documents or [APP HASH]/tmp folders. Unless you can find a way to initialize your app with your data in one of these folders, you will have to get your data another way. I have found the below code to work. Basically it downloads the local file into your temp folder and gives you the file entry.

window.requestFileSystem(LocalFileSystem.TEMPORARY, 0, function(fs){
    fs.root.getFile("temp", {create: true, exclusive: false},
      function(entry){
        fileTransfer.download(
                Url, // the filesystem uri you mentioned
                entry.fullPath,
                function(entry) {
                    // do what you want with the entry here
                    console.log("download complete: " + entry.fullPath);
                },
                function(error) {
                    console.log("error source " + error.source);
                    console.log("error target " + error.target);
                    console.log("error code " + error.code);
                },
                false,
                null
        );
    }, function(){
        alert("file create error");
    });
}, null);

Thank you so much. This stuff has driven me crazy and your solution works perfectly. And another trick is the uri should start with file:///var/blablabla

Glad it worked! I usually build my paths starting with location.href, which already has the file:///. That way I don't have to hard code the whole path.

Great! Thanks for letting me know.

window.resolveLocalFileSystemURI works fine in android for me. But does it would differ for ios. Please let me know.

@UnchartedSpace its giving me error as "ReferenceError: fileTransfer is not defined" how to resolve this for run your code?

@SaurabhAndroid You should post your code and problem as a new question. In the question, be sure to give your PhoneGap version along with some sample code and context, and which plugins you have installed.

@SaurabhAndroid FileTransfer is a different plugin than File... you are probably missing that.
