Bhai Eclipse abhi deprecated ho gaya hai, use Android Studio, but wo thora heavy hai.
And jo link 400mb ka hai wo 32bit Windows ka hai, aur 2nd link 64bit ka.
Agar source code app ka available hai to haan, otherwise no.
I wish I could post other parts too, but I'm too busy nowadays, and also main forums par nahi aata ab, so no posting
but aap ko Google par buhat se tutorials mil jaenge...
Sorry guys for late reply, I was and still am too busy.. :'(
