    App Debugging & Inspection Tool for Android

    Project mention: Looking for Android alternative to an iOS Jailbreak Tweak | reddit.com/r/androidroot | 2021-03-04

    Hello, I recently found this tweak http://cydia.saurik.com/package/com.shmoopillc.flexible/ but it only works on jailbroken iPhones. It basically lets you use Apple's "FLEX" debugger in any application, meaning you can use it in applications that you haven't made yourself. This basically lets you "inspect element" on any app you want. I found a similar debugging tool for Android (https://github.com/willowtreeapps/Hyperion-Android) but I was wondering if there was any way to tweak this tool and use it on apps you don't own? Thanks.
