Should I be optimistic about my profession and growth as an android developer, or should i start gaining experience in other domains?

I am currently a Junior Android Developer in a small company which is a subsidiary of a bigger company (TATA) . I currently hold a working experience of 3+ years but in last 5 years , I have mainly explored Android App development the most. I did courses in it, then internships, then switched jobs to reach a decent salary package (more than INR 10 lakh per annum).

Recently I have been pretty worried regarding my career choices and i can't seem to be optimistic about my role as a mobile engineer. I joined my current company 4 months ago, but my switch this time gave me a hike of -10% (you read that right, it was a negative increment since previous company was asking me to relocate and i had no choice but to take this offer)

This switch made me worried not just because of the salary decrement but as a worthy candidate too. I know my tech stack well , but this time, I had very less options. I feel that the demand of a mobile engineer seems to be very less and I am not sure if its only me or for everyone in the same space as I am.

So , are jobs of Native Android Development really dying? My goal is to reach at premium salaries of INR 80-90 lakhs or 1-2 crores per annum, so can I reach there while just being a good android engineer? I am not sure what to run for. Please help

Some paths that i came to conclusion are for me, based on my limited knowledge are :

CONTINUE ON YOUR PATH : Stay in 1 place , grow as an engineer, get your salary/ role increase slowly and you will probably be able to reach that amount in 5-6 years

SWITCH YOUR PATH TO OTHER TECH SKILL : Do web frontend/backend courses in your free time, then grab a job of 4-6 LPA , start as a basic web dev, grow into senior dev and then reach that amount in 5-6 years (coz frontend/backend devs are the real deal?)

SWITCH YOUR PATH TO HIGHER STUDIES : do courses to crack foreign exam papers, then take out all your savings and got to foreign to pursue some masters in management, then do a job there and get settled / come back to India and grab a better paying job as a manager, then grow/switch into lead managerial roles and earn the goal amount in 5-6 years (coz foreign studies are the real deal/ foreign countries give fair wages to skill?)

GET INTO BUSINESS : start a business of something , grow it, reach that amount in 5-6 years (coz doing business is the real deal and only way to get lots of money in black/white)

Which do you think is the most accurate/realistic?
