Cannot install whatsapp in android 2.3.4 I've a quite old version of android in my smartphone. I use whatsapp regularly, except yesterday where I had to try to update, and I couldn't do it because I don't have enough space on my smartphone. I've removed whatsapp and try the reinstallation but it doesn't work... Is there anything I can do? I read that there's probably some procedure I could try using both root privileges (that I have) and an emulated terminal.

This is not the first time that happens, usually I just remove apps that I don't use, but now I don't really know what to do.

Any suggestions?
You should know that WhatsApp is no longer supported on devices running android 2.3 and below. Newer updates​ won't simply install. The support had to end on june, and we're on june. 

You should consider upgrading to a newer phone.

However, in some exceptions, WhatsApp can be installed when you download directly the APK file.

Try downloading the file from here.
