I'm trying to install CCleaner on my v2.2.1 Android phone and I'm getting the message "there is an error parsing the package". I also have a language learning app that refuses to install too. I guess it is because they both require a more recent Android version. So my question is, how can I bypass this incompatibility and install them on my phone? Processing power is obviously not an issue. These are mostly text driven applications and won't have any demanding graphics or realtime performance that could not be achieved on an older device. My phone is rooted. Any suggestions are welcome.
