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

Hexadecimal color code for transparency

How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.

All hex value from 100% to 0% alpha:

In Google Developer Console inside your app project, on the Credentials section, you must create a new "Service Account" "Client ID", if you have not already. And download the p12 file. You need the service account key file, generated in the Google APIs Console into the same directory and rename it to key.p12.

On Google Play Developer Console you have to give permissions to "YOUR_SERVICE_ACCOUNT_EMAIL@developer.gserviceaccount.com" for uploading apks.

Installation

Download Google APIs Client Library for Python (google-api-python-client): https://code.google.com/p/google-api-python-client/ or use pip:

$ pip install google-api-python-client

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git
