android development tools (adt) plugin. Other development
tools are available, including a native development kit for
applications or extensions in c or c++, google app
inventor, a visual environment for novice programmers, and
various cross platform mobile web applications frameworks.
Memory management
Since android devices are usually battery-powered, android is designed to manage memory (ram) to keep power consumption at a minimum. When an android app is no longer in use, the system will automatically suspend it in memory – while the app is still technically "open," suspended apps consume no resources (e.g. battery power or processing power) and the device and sit idly in the background until needed again. Ensuring background apps don't consume power needlessly
Note:
Some Apps Take Too Much RAM Which Makes Device Slow,Lag,Hang &
