How to Make Full Use of Your Android Phone

If you are looking for Android assignment help, we can help develop any application that you can think of and provide you with fully commented source code, and an APK that you can install on your phone or tablet.

Android is programmed in Java, although not using the normal JVM (Java Virtual Machine). The best development environment is Android Studio, as it provides an emulator so you can check your program on your computer before you deploy it on the phone. Developing using an emulator offers much better scope for debugging that running on the phone as you can see the screen at the same time as viewing the code and the values as they are modified. Another advantage of developing using the emulator is that it allows you use a real keyboard instead of the virtual keyboard on the touch screen, which is much faster if you want to enter data.

When you start developing an Android application, you normally should add an activity that matches the type of application you want to write. Unlike developing in normal desktop Java, you don’t define the UI in the code but instead it is designed inside an xml document (or multiple documents if you have more than 1 view). You can use the design view so that you design the GUI using a GUI rather than having to write your own code. You can also include images (drawables) and sounds in a resources folder.

Android uses Gradle to convert all the Java files, and resource files into a single APK file (which operates the same as a JAR file does on the desktop). One complication on programming for Android is that the devices much more than is typically on a desktop, so a desktop application can pretty much assume at least a 1024 x 768 resolution monitor but an Android may be 480 x 800 (or 800 x 480 if the screen is in landscape mode), all the way up to 1440 x 2560, and unless you have multiple devices to test with you may need to use the virtual device manager, and you also need to consider the different versions of the Android operating system which are much more than numerous than Windows 7, Vista and Windows 10.

Android applications also need permissions, it is a good idea to limit them to the minimum set that are required as people are more likely to install an application that does not require granting access to everything under the sun.

Finally you need to sign an application if you wish to make it available to others to download from the Android Play Store, this enables Google to guarantee only you can update the application and to provide a form of liability insurance since they know that you wrote the code and are guaranteeing that it is not a malicious application.
