How to play YouTube videos & music in the background on Android (root)24
Anyway, developer Pyler was up for fixing this rusty little bolt of Android's, and not only did he nail it, he made it super-easy for everyone with a rooted device and the Xposed framework installed. If yours doesn't meet these requirements, you'll have to think long and hard whether voiding your warranty is a worthy trade-off for seamless YouTube streaming.
Should you choose to do so, look up an up to date guide on rooting your smartphone - we can't write one for each smartphone on each Android version out there - and installing Xposed. In most cases, it's a walk in the park. When you're ready to proceed, turn your attention to the slideshow. Thanks, Pyler - you seriously made our lives better!
