What project to create for Android?

Question

Android

Hello.
There is a study task - to write any program for android ..
There was an idea - about writing a network sniffer (I realized that it was not strong enough yet) and decided to postpone it.
All the same, in search of ideas ..
(I am mainly interested in applications for the network, for the OS itself, such as tracking system processes, like the AIDA64 program, traffic tracking, password manager).
These applications are of personal interest to me, I wanted to know if the ones listed are suitable for a beginner android project?
I have experience in practicing a finished project in JavaCore / JavaEE (Web Services with jersey framework) +
Mysql
.

Answer 1

about writing a network sniffer (I realized that it is not yet strong enough)

There is nothing particularly complicated there, you can decompile, disassemble existing ones, which also contributes to a deep study of Java, Dalvik, Android.
Task manager like in Windows: list of processes, how much RAM and CPU time each takes, etc., what is the total CPU load, network, etc.
Это к преподавателям вопрос, вообще для учебы обычно осваивают более широкие темы, такие как базы данных, сети.

Answer 2

работа с бд в android отличается от работы с бд в spring
поэтому не смотря на опыт я бы советовал какой то rest клиент
