Hibernate应用程序，但让他们在短时间内定期醒来 -- tasker 领域 和 battery-life 领域 和 automation 领域 android 相关 的问题

Many of us Android users have probably already heard of Greenify xe2x80x93 an app that can automatically hibernate apps as soon as you turn off the screen. That even works while keeping their GCM functionality working xe2x80x93 so whenever a cloud message for them comes in, they get awake again.

Unfortunately, that wakeup only works with GCM. Now I want to hibernate a non-GCM app, but have it awaken in intervalls (eg. de-hibernate it all 30 min for 1 min, then auto-hibernate it again).

Is this possible xe2x80x93 and if so, how?

My device is rooted, the XPosed framework is installed, and tasker available as well xe2x80x93 so solutions involving one or more of those criteria are perfectly welcome as well.

Oh well, oh my xe2x80xa6 question almost included the answer. Still needs some testing (I've just set it up now), using tasker which has a Greenify plugin:

• Condition:
  • Event xe2x80xba Display xe2x80xba Display Off
• Task:
  1. Task xe2x80xba Wait: 20 s (just in case)
  2. Task xe2x80xba Anchor: (Name, optional step)
  3. Plugin xe2x80xba Greenify xe2x80xba Hibernate: Pick the app
  4. Task xe2x80xba Wait: 30 min (or however long you want to have the app hibernated)
  5. Plugin xe2x80xba Greenify xe2x80xba Wakeup: Pick the app againxc2xb9
  6. Task xe2x80xba Goto: Action Number, 2
• Exit Task:
  • Plugin xe2x80xba Greenify xe2x80xba Wakeup: Pick the app againxc2xb9

Note: That's how I would set it up. Had to skip the exit task as Tasker won't let me add one. So that's the crux here: I have to trust Tasker to restore the "previous state" correctly. If that doesn't work, I'll have to create a second profile for Event xe2x80xba Display: Display On (which would, being an EVENT, fire when the display will be turned on xe2x80x93 it's not a state) and have a single task to do what otherwise the exit task would do.

Note 2: In order for this to work, you need to add the "target app" to Greenify's hibernation list first (i.e. tell Greenify it should hibernate it when turning the display off). If you don't do that, it won't ever be hibernated at all.

xc2xb9 _{if your app doesn't react on the wake-up command, see Xavier's answer for an alternative shell command to try}

I found out some of the hibernated apps wouldn't respond to the Greenify Wake command, instead I used the start service command to "wake" the target application (without opening its UI)

Profile Context

• Event xe2x80xba Display xe2x80xba Display Off

Task

• Click "+" to add new Action

• Task xe2x80xba Wait: any preset e.g 20s (like above)

• Task xe2x80xba Anchor: (Name, optional step)

• Plugin xe2x80xba Greenify xe2x80xba Hibernate: Pick the app

• Task xe2x80xba Wait: 30 min (or however long you want to have the app hibernated)

• Code >> Run Shell [ Command (am startservice -n com.package.name/.service name , Tick "Use Root"]

  NB: service name is just a declared service in Android manifest that starts an application without opening UI i.e in background, there are also tools to use if you're not sure of the service name)

• Tap back to exit from this task

• Click "+" to add another action

• Task >> Goto [Action Number, 2 (anchor task)]

  Like @Izzy said you can rely on Tasker 'previous state' to reset the config, because adding an exit task is not probable

My workaround simply involves starting the service of the hibernated app (IMO=waking the app) because sometimes the app won't wake up using the Greenify wake option as I previously encountered :)
