How to Analyze & Manage Memory on Android Like a Boss
Analyze & Manage Memory on Android Like a Boss
This Blog is all about memory management in Android. It provides information about how you can analyze & reduce memory usage while developing an Android app.
Memory management is a complex field of computer science and there are many techniques being developed to make it more efficient. This guide is designed to introduce you to some of the basic memory management issues that programmers face.
Memory Management in Android
Android is a Linux based operating system. It uses native open source C libraries which power Linux machines. All the basic operating system operations like I/O, memory management and so on are handled by the Linux kernel. Like Java and .NET, Android uses its own run time and virtual machine to manage application memory. Unlike either of these frameworks, the Android run time also manages the lifetime processes.
Each Android application runs in a separate process within its own Dalvik instance, relinquishing all responsibility for memo

Message of Issue: "Screen overlay detected - To change this permission setting you first have to turn off the screen overlay from Settings > Apps"
Scope of issue: This only applies to Android M (6.0/API v23) Or Over
Explanation: Other apps installed on the users device may be utilizing a screen overlay on your phone (e.g. Twilight, Red Moon, etc...)
Screen overlays are virtual layers that cover part or all of screen while another app is in the foreground.
It may be dangerous for android to allow you to to change a sensitive setting while an overlay is active because you may prone to 'tap-jacking'
(i.e. a malicious application displays a fake user interface that seems like it can be interacted with, but actually passes interaction events such as finger taps to a hidden user interface behind it.).
Therefore to improve security, android doesn't allow you to change sensitive settings while an active overlay is detected, unless the user permits the app to do so.
Use keytoolKeytool is part of Java, so make sure your PATH has Java installation dir in it.
Get APK Certificate Signature
First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA or something.RSA, but there should only be one .RSA file).
