Running ver 6.0.1 . i get this message every time i boot the phone as of last night. android is starting... optimizing app 1 of 1 . this goes on for quite a while - i would say somewhere in the area of 15 minutes.. Android is starting... optimizing app 1 of 1. - bad app installation - android system software update is not optimized apps properly. full load your phone. turn off, disconnect from ac. start and wait for the optimization process to come to an end. check settings>battery for app using most battery. deinstall that and reboot.. Android 5.1 random restarts and optimize app showing 1-1031 of 1031 messages. can you please clarify what you mean when you wrote "optimize the apps after restart"? re: android 5.1 random restarts and optimize app: android 5.1.1 is starting to roll out. it will go ota to the google play devices first but the images are.
It goes through the motorola loading screen with the stitching animation but whe my lock screen should appear a white pop up appears infront of a black screen saying, "android is starting: optimising app 1 of 1" where it gets stuck.. After doing some digging it seems like this happens when android has a problem optimizing one or more apps, so it stubbornly retries all of them. so i uninstalled apps one-by-one and rebooted, and the problem went away after uninstalling supersu.. What optimize apps does is convert the apps' opcode to art-compatible way. lollipop moved to android runtime with the release of lollipop which insures that apps run faster. one of those methods is ahead of time complication, which is what this screen is about..
