Android: Push Messages, Download ZIP files, Webview

We are reposting this project as communications with the bidder have not been sucessful, and we need to add two important items to the project. This project is for a tablet device with a screen resolution of 1080p. It will run on an Android device running 4.2 or newer. It is a two part project: Main App: This app must contain a full-screen WebView, with double-tap zoom turned off and objects scaled correctly. -Receive & send Google CCS messages. Upon receiving a push message, the application will need to download the specified URL in the message (the URL being a remotely hosted ZIP file). The password-protected ZIP file needs to be downloaded and extracted to the sdcard directory. Once the ZIP file is extracted, the app needs to send a “download confirmed” message to the CCS server. The filename of the zip file should be stored in a string that is accessible when the app is closed and reopened at some point. -Detect if a USB Flash drive is inserted. If it contains an .apk file: copy it to the sdcard directory and launch the Secondary App. If contains [login to view URL], call a blank function (placeholder). -Developer should setup a simple working CCS server example (PHP is preferred). -NEW: When an HTML form inside Webview is submitted (could be 20-30 a day), store the contents in a text file/CSV and upload them when a network connection is available. (this is to capture leads when the device is out of network range). -NEW: When a user holds two fingers in the upper left corner of the screen for a period of 5 seconds, load a specific URL in Webview. Secondary App: -A separate application will also need to be developed which, when opened, will close the Main App and copy a .apk file from the sdcard directory and replace the existing Main App .apk file (in other words: very basic application updating functionality).
