There are a number of "ifs" to an answer.
- If you are already comfortable developing apps for Android (more so than developing for Windows, or OS-X, or iOS, or the web, or even Excel macros), and
- If you will be doing this as a hobby, and
- If you have a solid grasp of chromatography principles, then
Yes, it would be an interesting project.
On the other hand,
- If you're looking at Android as "the platform of the future", or
- If you expect to make any money at it, or
- If you will have to learn chromatography in the process,
then you will be disappointed.
- On a global basis, Android is ahead of iOS as a smart phone operating system (probably not true for tablets), but in a lab environment it is far far less common than Windows.
- Android apps (and iOS apps, for that matter) are typically either free or priced at a few dollars (the most expensive programs run around $30). There aren't that many chromatographers in the world who be allowed to use an Android app at work to make it pay.
Sorry!
By the way, your English is fine.
