On the off chance that you have to step up your Android diversion, quit shying far from the internal functions of the Android SDK and begin get to know it.

2. Attempt to get over the Fear Of Missing Out (FoMo)
Android is huge, huge. You can't learn it totally end-to-end in multi month or two or something like that. The more you learn, you will discover significantly increasingly new things coming your direction. As a novice, it's consummately ordinary to have a dread of pass up a major opportunity.
In any case, endeavor to get over it. Take in the things that you truly need to learn so as to begin with the application you are as of now building and after that gradually extend your viewpoint.

Most engineers don't haul out time to peruse what different designers are composing. They simply invested a large portion of their energy composing what they definitely know.
In any case, that won't enable you to develop as a designer. That would not expand your insight. You should begin taking a gander at other open-source applications and libraries and begin learning. 30 minutes of code perusing ordinary is a decent begin. You will be shocked to find such huge numbers of new things you had no clue about.

4. Think about adapting more dialects
I am not instructing you to learn Spanish or Chinese, but rather to learn new programming dialects. You have to keep yourself refreshed with what is going on in the business as opposed to binding yourself just with Android constantly.

This will open up your viewpoint and will enable you to enhance your Android advancement abilities altogether. Decide to learn no less than one new programming dialect consistently. In any case, don't simply skim over the dialect for a week and abandon it. Endeavor to get into the profundities of the dialect and how it functions inside.
