a troubleshooting guide for DFInstagram
I can't install any version later than 1.1.1
Google recently stopped supporting 32-bit applications. This meant that we needed to update the application from the old 32-bit version to 64-bit so that it could work with newer phones.
Alternatively, you might have a phone that uses an x86 processing architecture rather than an ARM architecture. We only support ARM architectures because they account for the great bulk of the smartphone market, and maintaining separate versions would be too much work for our small team.
Check this tutorial to find out the processor architecture of your phone.
I get an error saying 'Application appears to be invalid'
Have you made sure that you uninstalled the original instagram app first? If you already have dfinstagram installed, try uninstalling it then reinstalling the newer version.
