Cordova developer needed.

We developed a mobile app made by cordova(monaca), but there are few bugs. please resolve it. monaca: [login to view URL] /* The bugs are as follows. */ #1. Cannot download all the movie files from the host. We download the movie files(mp4) from the host with File transfer plugin(File API) which monaca provide. It succeeded when the number of the movie files are less then about 20, but it fails when they are more than about 20. * There are 151 movie files in the host now. Save destinaiton: [login to view URL] We guess the reason is memory leak from the fact that the app suddenly crash when the downloading process. #2. Cannot generate the thumbnail from the movies. We generate the thumbnail image from the movies which was saved in app with the file transfer plugin(File API). Concretely, The way to generate is to use video tag and html canvas, save the image object to the app. * Save destinaiton: [login to view URL] /* The specification of the app. */ The simple app to see the movies which download from the host we provide. * The user needs to download the movies from the host with Sync button. /* System requirements. */ ・Xperia Z2 Tablet (Android OS Tablet) ・Don't need to support iOS for now /* Due date & Budget */ Due date: within 2 days (03/30) Budget: Please give us your estimation. * We attached the source code.
