i was wondering if there was an app for android that is like cydia. i want an app that has a huge collection of tweaks, hacks, roms, scrips, apps, themes; just like how cydia (for ios) has. im not looking for apps like app-toid or 1-market.
Xposed Framework is an alternative to Cydia on Android.
but that doesn't work on Android 5.0 just yet. An Alpha-Version was just made available. The installation process is different though and it is still buggy. Only works on Arm7 chips so far.
I guess Cyndia App is already available over the PlayStore for Android.
PS: Correct me if, you are talking about something else.
There are many app repositories available for android besides the play store. A Google search will reveal them. There are apps on the play store that only work with rooted devices, too. The iPhone is more closed than an android device. For the iPhone, Cydia is the source for alternative apps. That problem does not exist with android.
