Spotlight: Memory Locker prevents Android apps from being killed by RAM management

Having trouble with your smartphone's multitasking, due to low RAM memory or the way its Android build handles app management? Grab Memory Locker and fear not. This app prevents running applications from being killed by Android's memory management subsystem. Android sometimes kills any running application because of low memory.

For example, some Android users, especially ones using low memory devices, have problem with the OS killing the launcher. Surely you must have had that happen, when your launcher is killed and then it takes some time to restart. In such cases Memory Locker can reduce the risk or outright prevent it from being killed.

Being a power user app, Memory Locker lets on select which applications they want to prevent from being killed. This means the feature is also useful for widgets on your home screen, because it minimizes the risk of widgets stopping to run.

Memory Locker works by modifying files in the /data directory, and also controls system files in the root folder for setting the oom_adj value for all running processes. All locked (memory-protected) applications are automatically locked after each reboot, so you do not need to lock your applications again after each reboot.

Memory Locker is free and can be downloaded from Google Play.
