Android is an operating system that is built basically for Mobile phones. It is based on the Linux Kernel and other open-source software and is developed by Google. It is used for touchscreen mobile devices such as smartphones and tablets. But nowadays these are used in Android Auto cars, TV, watches, camera, etc. It has been one of the best-selling OS for smartphones. Android OS was developed by Android Inc. which Google bought in 2005. Various applications (apps) like games, music player, camera, etc. are built for these smartphones for running on Android. Google Play store features more than 3.3 million apps. The app is developed on an application known as Android Studio.
The App components are the building blocks of Android. Each component has its own role and life cycles i.e from launching of an app till the end. Some of these components depend upon others also. Each component has a definite purpose. The four major app components are:
Activities: It deals with the UI and the user interactions to the screen. In other words, it is a User Interface that contains activities. These can be one or more depending upon the App. It starts when the application is launched. At least one activity is always present which is known as MainActivity.
So before working on real-world projects, it is suggested to create some sample projects in android studio and get a taste of project creation as well as execution. Here, you will find the 100+ Android Project Ideas with source code and stepwise explanation.
ne of the best ideas to start experimenting you hands-on Android projects for students is working on Android based Function Generator. This Android-based function generator features an output range of audio frequency signals around 20Hz-20,000Hz emitted through the audio port of mobile phones (usually, 3.5mm audio jack). The functions available on the Android-based function generator include sinewave, square-wave, triangular-wave, and sawtooth-wave, all within the 20Hz to 20,000Hz range. To test the signals generated by this function generator, you can use a digital storage oscilloscope (DSO) and Windows PC-based CRO software . Lastest MCA Projects Topics Titles Ideas 2022 2023
You can amplify the signals using an amplifier if you want to interface the function generator with other external devices. However, you must ensure that you use an appropriate protection circuit to avoid damaging your mobile device.
