Development starts once the designs have been approved and sent across to the developer with the color codes, pictures and in the case of the icons the developer requires either png or tff depending on whether it is single color or multi colors.

1. Most common problems faced by a developer
1. Designer changes the design and developer has to change complete coding
Development starts once the designs have been approved and sent across to the developer with the
color codes, pictures and in the case of the icons the developer requires either png or tff depending
on whether it is single color or multi colors.
2.Number of devices with different screen sizes :
The launch of a new mobile device every few months with varied screen sizes has increased the
work load of the developers. The app is first made on a particular screen size say for a smart phone,
but since tablets and notes are also available in the market , the developer has to change the layout
and increase the screen size, font size for all the different screen sizes.
3.Android is releasing the new versions on a very little time interval developer need to keep update
for these updates:
Android version started with the release of Android alpha in November 2007. If we look at the
history of android version updates, a new version is released atleast twice a year.
When a new version is updated on a mobile phone the developer has to change the codes
accordingly for the app to be compatible with the new version.
4. Project is never complete
There are some clients who are not clear about the screens at first so they use hit and trial method to
arrive at their final choice of screens and every time a change is made, the developer has to make
those changes to show it to the client. This increases the work pressure and hence the work is never
really complete.
5. Understanding the code of someone else
Developers mostly use API's . Using an API is easy, but understanding someone else's code takes
time. It requires careful studying of the codes and coming up with solution to use them in the app.
A few apps would require two different API's which is double the work because after understanding
both, they have to be linked to each other.
6. Offline working of App
Applications either operate offline or work with internet access. But offline working of an app
requires that the database that is being maintained on the device end be synced with the database on
the server end so the effort and work is more.
7. If Server end is handled by different company and there is always a communication gap
The problem that arises here when the data is not available in house is that the data that is available
is not as per our need. There is always a compromising factor involved, whereas the in- house data
is easier to understand as it has been developed by someone among us.
8. Optimization issue
The most challenging task for a developer is to optimize the codes that is to write smaller codes
instead of the bigger ones which uses less space in the app and easier to download and use. The less
heavy the file the easier it is to download and update.
