Development of a simple Android application

An Android application is a mini-game that identifies a user based on a set of criteria and decides whether to launch the application or open the specified url in a webview (or customtabs). Identification criteria. IF: 1. GEO. The ability to set the required geo of users, for example, people only from Russia. 2. The user is using a mobile phone. 3. The phone has a sim card of one of the specified cellular operators (list of operators) The Internet can also work via WIFI, but the presence of a sim card in the device is required. 4. Mobile phone NOT Google Pixel TO: The application opens a webview (or customtabs) and loads the url. (The condition is met if all criteria are true) ELSE: the native application (mini-game) is launched (The condition is met if at least one of the criteria is false). Mandatory need: 1. Store user login cookies. 2. Remember what was shown to the user and show it further. 3. In the menu, have a Policy button. Policy opens in webview (or customtabs). GEO, Mobile operators, Policy, and URL are conveniently stored in Firebase (or somewhere else) for quick adjustments without changing the application. MINI game. Any variation on the theme of volcanoes will do. - You can make an analogue of the sapper game on windows, but instead of mines there are different volcanoes. - Game - extinguish volcanoes. Several volcanoes that are about to explode and they must be extinguished with water, earning coins. - Guess which volcano will explode. Many different volcanoes are slightly animated. Some of them are mined. Guessed - earned a coin. - Volcano miner. I chose the first volcano, tap on it and help it erupt. We earn points, open other volcanoes. Any flight of fancy. A simple, small 2d arcade game about volcanoes will do, the main thing is uniqueness. In addition to coloring books, puzzles, and quizzes. We can help with graphics if that's a problem. You cannot use code that has already been used in other applications. Those. code must be unique. Graphics must be unique, if they are taken from open sources, they must be redone. I can provide a designer. Please, write immediately proposals with the price.
