How to use FileTransfer.download on Android

Question

I use Phonegap 1.9.0 on Android, but there are few examples on the Internet, so I'm worried about downloading the file.

var ft = new FileTransfer(); ft.download( "http://www.something.com/test.zip", "test.zip", // <- Trouble 1 function(entry) { alert("success"); }, function(err) { alert(err); // <- Trouble 2 } ); 

1. I do not understand the way of specifying the file path suitable for this argument. How to specify a local path? Or is there any necessary Android.permission?
2. The message "Class not found" is displayed. What is the reason?
3. What is the path in the native Java uploaded file?

Answer 1

Yes, Cordova / Phonegap docs are very easy with real-world examples!

• Simon Mac Donald has a great download article: http://simonmacdonald.blogspot.co.uk/2012/04/sorry-for-being-gone-so-long-vacation.html If you want to upload multiple files, check out its contents: https://gist.github.com/3835045

• I think that FileTransfer is only available on the device (maybe in the emulator?), But I also get this error in the browser - maybe someone else can trick the explanation / workaround for this.

• It depends on the platform, but it can be found in the FileSystem.root.fullPath file. If you add file names, you need to add a slash.

 // This worked for me var ft = new FileTransfer(); ft.download( "http://www.something.com/test.zip", // what u download "/sdcard/test.zip", // this is the filename as well complete url // fileSystem.root.toURL() + "test.zip", use ios and others function(entry) { alert("success"); alert(JSON.stringify(entry)); }, function(err) { alert(err); alert(JSON.stringify(err)); } ); 

You can check the directory structure in ADT Eclipse DDMS Perspective -> File Explorer
