A lifeline Android can't tell all opened

[Android Central Question]

Don't show all Web open apps or how to be sure are closed

 

[B. Diddy]

Welcome to Android Central! Sorry, can you clarify your question? Are you asking how to tell if apps are closed? With Android, there's no need to completely close an app out of memory. The system will decide when it needs to clear an app from RAM if it needs room to open another app. Android prefers RAM to be mostly full, which is the opposite of Windows, which tends to work better when RAM is mostly empty.
