This is the CyanogenMod 12.1 Gallery2.apk with Material Design compiled directly from CM sources.
Just download and install the apk.
- Compatible with all ROMs Android 5.0+. (tested on Xperia Z Ultra running 5.1 GPe port and Nexus 5 running BoostPop and ParanoidAndroid)
- Does not require root.
Why would you need this?
AOSP ROMs like CyanogenMod and Euphoria OS: already included, will only overwrite the preinstalled version.
Google stock ROMs (Nexus and GPe): not included, feel feel to try.
Other OEM ROMs like TouchWiz: not included, feel free to try.
Other minimalistic ROMs (like BoostPop) that don't bundle the AOSP Gallery: not included, feel free to try.
I take zero credit for this apk. I did not write the code - I merely compiled it from CM's source with integrated libraries. All credit goes to the Android Open Source Project and CyanogenMod.
Since I did not actually write the code, I might not be able to solve any of your issues with it.
No mirrors please!
