Android Install different versions of same app together, possible ?

[raksrules]

I have a rooted android tablet and need to know if I can install same app twice but different versions ?
Say I have hello world_v1.apk and hello world_v2.apk, both residing in the same tablet together.
Is this possible ?
Also both need to work and no force close or anything.

You need to change the name of the apk of one of them. But all apps might not play well with this and might break, so you should just try and see if it works for your app. Instructions for doing this from PC and android can be found in the links below:

Another way : Install Android L if it's available for your tablet and then use the Multi-user option it provides.
I was able to install and use 2 WhatsApp apps in different user profiles this way.
Should work in tablets as well with the multi-user support.

I have a parallel question to this. Say I have a Dual-SIM phone with both numbers active. Can I have Whatsapp on both numbers? Or would I need to install 2 different Whatsapp versions/flavours?

AFAIK WhatsApp only works with one number per installation.
Workaround for your question : Use Multiple User profiles (Android 5/L onwards) and install it on both profiles and you can use both numbers together.

LOL I had an old version and the newer version of Tapatalk installed for pretty long, but thanks to them that their new update was much less horrible so I could peacefully uninstall the old app.
