Write an Android application to compute & verify a cryptographic hash plus other functionality

The chosen developer will design a simple 2-screen Android application whose principle purpose is to compute a Cryptographic Hash Value of a file or text string and verify against a pasted hash value. You may wish to download and test HashDroid; this app has a similar intended purpose. Greater detail is below. However, please review these important guidelines before submitting your proposal: 0. The selection of a developer will be based on best value rather than lowest price. Please consider this when submitting your response. 1. Please include a brief but relevant description of your experience building Android applications. 2. Please include a brief but relevant description of your experience working with cryptographic hash functions. 3. Indicate the full list of hash algorithms that can be supported. 4. Indicate the recommended API Level for an application of this type. Also provide a list of the screen resolutions/devices you will support in building the app at the proposed price. 5. Please include any suggestions or possible omissions from the description of the application below to achieve its intended purpose. 6. Please include what responsibilities are required from me during the development process. Below is a partial design spec highlighting key functionality. The app will consist of just two "screens," which for the purposes of this build description will be labeled Screen 1 and Screen 2. Graphic design decisions are to be determined and may be subject to change. Screen 1: Will feature the application logo, a stylized background, a chooser to select the hash algorithm to be used, and buttons to select a File or Text as the source of the hash value. The File button will launch a chooser so the user can select the file for which he or she wishes to obtain a hash value. The Text button will launch a small text input window in which the user can input their text via the device's keyboard or paste. Screen 2: Upon selecting a file or entering text, the user will be displayed a second screen that will include a progress bar to show the progress of the file hashing process. Upon completion of the process, the progress bar will disapper and the result of the hash function in hexadecimal format will appear. Below the output will be a button that if pressed will copy the output of the hash function to the clipboard. Additionally, there will be an empty text field in which the user may paste a hash from another location. A message below this text box will change depending on whether the current output and the value in the text box match. The three messages are as follows: 1. Paste Hash to Verify (when text box is empty) 2. Values do not match! (when text box has a value but does not match the output) 3. The values match! (when the text box value equals the hash output) Below, two additional buttons will be available to the user that are labeled and function as described below: Button 1: 'More Information' - When pressed, this button will redirect the user to the default web browser to a google query that will contain the hash value. Button 2: 'Get another Hash' - this will bring the user back to Screen 1. At the bottom of Screen 2, the developer must incorporate Google Admob advertising for which I will provide you my account details. Other functionality required: - The user must have the ability to select the app when using the "Share" function everywhere in the operating system. Doing so will bring the user directly to 'Screen 2' where the data to be shared goes through the hashing process. Terms including but not limited to (full terms will be presented to the developer upon their selection for this project): - The app will conform to the Google Core App Quality guidelines. - The app will be fully prepared for build. - The developer will provide all source code for the project in a form that is accessible by either Eclipse or Android Studio.
