For the last few days, I’ve been having a problem with my Samsung Galaxy S II mobile phone running Android 4.1.2 (JellyBean) in that the Google Play store (which is used to download/update apps) just kept crashing. Sometimes it’ll load and showing a “Loading” screen before turning black and closing, other times it’ll just flash a black screen. I also got the “com.google.process.gapps has stopped working” when restarting the phone.
I did try going into Settings->Application Manager and stopping the Play Store, clearing the cache, uninstalling the updates: all with the same results. What did fix it however, was going into Settings->Application Manager selecting “All” finding “Download Manager” (which was right at the bottom of the alphabetical list!) and selecting “Enable” (for some reason, it was disabled). Reopen the Google Play Store and all seems well.
I’ve got no idea why the “Download Manager” became disabled nor why the Android PlayStore uses it.
