My suggestion is to try to install linux (point 1) (maybe with the help of a friend), because it's important to have the latest SDK version and the latest updates. Get detailed information on Adobe Photoshop CC 2019 v20.0.1 for Mac or any other software title from our webshop or just email one of our representatives. You can try to download and run the first Android Develop Studio Beta that ever appeared on the website (0.8.0), I don't think they ever supported 10.7.5, but you can try. Check to see what version of JDK worked on 10.7.5, install it, then install one of the versions of eclipse from Indigo to Mars and then install the above mentioned plugin. AppCleaner finds all these small files and safely deletes them. Installing an application distributes many files throughout your System using space of your Hard Drive unnecessarily. Go with the previous Android Development solution : Eclipse IDE Indigo or higher + ADT bundle plugin. AppCleaner is a small application which allows you to thoroughly uninstall unwanted apps. There you can install the latest version of Android Studio with no hassle.
You don't need to update your Mac OS 10.7.5, it will remain intact, but you will boot on linux to develop Android Apps. You install ubuntu (I recommend Linux Mint 17.2 'Rafaela' - Xfce RC (32-bit) as it's lighter on your CPU and RAM) and dual boot. There are three options from what I see here : Access Microsoft Office for Windows and Internet Explorer Run more than 200,000 Windows apps on your Mac without performance issues Develop & test across.
