Get Information about System Resources with NotiSysInfo
Android, like every other operating system, consumes lots of storage space and Random Access Memory. The validity of third party task killers is for another, very long discussion. But even without killing apps in the background, accessing some information regarding resource consumption is often quite problematic and requires a lot of tapping through settings.
The notification shade seems to be a perfect place to find such information, and XDA Forum Member zsoltz made an application to show RAM usage and free space on your SD Card. You may ask: Why not a widget? The answer is quite simple, as not every launcher supports them. Notifications are fully customizable, so colors can be changed for the selected bars. The service can start at boot, so users don’t need to restart it every time the device starts.
By default, the application refreshes every 10 seconds. You can set up a shorter interval, but keep in mind that more frequent refreshes lead to more battery consumption. NotiSysInfo doesn’t require root or any special prerequisites, so it can be used on every running Jelly Bean or KitKat.
If you want to have information about resources of your device visible, make your way to the application thread to give it a shot.
