Overview:

With the growing boom of the Android Smartphone, the technology in the iphone app development is also advancing, and the Android developers have to be acquainted with the latest knowledge of the challenges and advancement that is occurring in the Android world. Some of the basic lessons that have to be understood by the Android app developers are as follows:

New and Important Lessons for Developing Android Apps

1. Minimum SDK:

This popular OS comes with its own Software Development Kit (SDK) with its own unique development and design features. Many of the new apps are only compatible with the latest Smartphone and do not function properly in the older versions. So, while designing the application, the developer has to have a good idea of the target audience to cover. If the purpose of the application is to promote the latest Smartphone, then the SDK level will be set of high value featuring the latest development codes, compatible with the new models only. However, if the purpose is for maximum usage of the app, then the minimum possible SDK level has to be selected so that the application can run with a large number of devices, both the old and new ones.
2. User Interface:

Several new features have been added to enrich the user interface of this OS powered devices. ViewGroup is a new HTML coding done for enriching how Android apps will be placed and managed by the user. The grid lines form the basic layout of the display of any app. ViewGroup allows the developer to modify the grid lines so to expand the flexibility and adjustment ability of the device. With large screen Smartphones, this is a vital lesson to learn, as the visualization ability of children, youngsters and adults differ. What need to be done in this respect is to adjust the grid line with respect to the application, so that the color sharpness and color contrast is adjusted automatically when an application runs.

3. Adding the Action Bar:

Adding the Action bar can be intricate for the Android app developers if they are now aware of the basic features and limitations that has to be taken into account before the Action Bar is developed. Action Bar should be able to recognize recent and related activities of users and suggest them with recommendable activities or apps as per their interest’s match. It is supported by Android 3.0 or above and Smartphones with an older version of Android will not function or will not function properly with the Action Bar setting. In case that you want to add the Action Bar in devices installed with older versions of the operating system, then either you upgrade the operating system or include the Android Support Library in the program files of the application.

4. Audio Hardware Setup:

While recording an audio file, it is hard to maintain the frequency of the audio within a given range. Speakers saying something might lower their pitch which is not detectable by the device audio recorder. The coding of ‘public void onReceive’ helps the Android app developer to adjust the frequency setting of the device so that very low frequency of audio can also be detected and recorded.
