Files under Apps & Plugins
If there could be one smart platform on which developers can roll around and take pleasure in working with developing applications, then it must be obviously the Android platform.
Yup! Developers are delighting on building applications that look and feel great over the several hundreds of devices enfolding different combinations of screen sizes, pixel density and aspect ratios.
Though these diversities provides enumerable challenges to developers, in some way developing apps for androids have become a quite needy and passionate thing in today’s world.
Tips to Beginners:
One best thing with android is it has got an excellent persistence system. Android devices make your applications more vigorous under unsuspected failures and shutdowns.
It is Android’s SQL based storage system that integrates it with user interface classes. It supports the observer pattern in cursor, adapter and view classes thereby enabling the user interface to connect straightly to the results of database queries.
The database classes in Android application development framework is well versed in managing cache and are also reading the entire data model into objects in the memory. However, in order to take the maximum benefit of android app designing, you would definitely have to learn some SQL.
Eclipse, though being an easy learning factor for beginners, getting relaxed with it is quite huge, powerful and perplexing IDE is a greater part of being productive in Android application development. Java, if without the productivity features of Eclipse is of no fun or look.
It is not a rule that you should know a large amount of XML to use visual editing tools for defining layouts and other resources. It is good that you know a little bit of XML and the way android uses XML and the android XML schema, from which it is easy to fix problems that occur in XML in Android applications.
Using Automated Testing
Utilize the Monkey to test your application, which performs a series of activities like simulating random inputs, generating a stream of events and reports application crashes or lack of response. Instrumentation framework and JUnit can be used to write unit tests which can be then run from Eclipse using adb.
Use static analyzers
Static analyzers are quite a significant factor to consider while developing for android devices. Java is good to exhibit meaningful compiler warnings and other warning which are based on static analysis.
With static analyzer methodology, you can overcome all potential bugs prior to leaving your application for development. This could even help your app to earn a 4 star rating instead of a 2-star one.
Make use of the compiler warning to find bugs and also the tools which find most of the problems faced in a typical android app.
Divide large applications
Never, never go with a larger application. Consider dividing them into a bunch of applications and services, since smaller apps only loads faster and use fewer resources. In addition, you will be showing signs of success in each application you come up with instead of the single large one you’re developing.
Design for low power consumption
Making your android app for low power consumption, will help in keeping up the life of your handset’s battery. Apps when cutting down in every ten minutes will sure affect the life of the battery. Hence, design it on lower power consumption rate than that of PCs.
Apart all make you app android-friendly
It is important that you use the application and service lifecycles effectively. Ensure that your application is efficiently stopped and restarted by the android system.
Android’s runtime environment stops frequently and ends the process in order to keep application resource consumption low. It prepares to restart the processes when a user navigates back to an application. All that android expects from an application is co-operating with the way it manages application as they become visible on the screen.
So, these are few tips which would help you greatly in android application development, both as a beginner and as an expert.
