Android App Fundamentals (Lesson 2)

-
Android apps can be written in Kotlin, Java and C++ languages. The Android SDK Tools compile the code and along with resources and create a package in .APK, an Android Package format. Let's see some special features of Android apps. The Android operating system is a multi user Linux operating system which each app is a different user. System assigns each app a unique Linux user ID. System is in control of setting permissions for each app. Each process runs in it's own Virtual Machine, so one app can't access others data directly. Each app runs in its own Linux process. System shutdowns the process when process is no longer needed or when system needs to recover memory for other apps. App can request permission to access user's contacts, SMS messages, the mountable storage (SD card), camera, and Bluetooth. Without users permission grant apps can't access those services. App Components App components are the building blocks of the Android apps. There are 4 d

Flutter - Create Image Container with Round Corners and Splash Effect

-
Image
Introduction In this article I'm going to explain you about how image with round corners and splash effect is created using Flutter widgets. Before doing some coding, let's see how images are loaded in Flutter and what the splash effect means. Images in flutter In flutter apps, we can load images from network, assets (App resources) or from the file system. Loading images from network is very easy task in flutter using Image.network constructor. Image.network( 'https://raw.githubusercontent.com/flutter/website/master/src/_includes/code/layout/lakes/images/lake.jpg', ) If you want to load images from network and cache it for offline usage, you can use CachedNetworkImage widget. You need to add cached_network_image dependency to use it. Click here to see installation instructions. CachedNetworkImage( placeholder: CircularProgressIndicator(), imageUrl: '

AVR Analog Comparator

Image
Introduction AVR Analog comparator can be used to compare two analog inputs. The Analog Comparator compares the input values on the positive pin AIN0 and negative pin AIN1. When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin AIN1, the Analog Comparator Output, ACO is set. the comparator can trigger a separate interrupt, exclusive to the Analog Comparator. We can select Interrupt triggering on comparator output rise, fall or toggle. Following is a block diagram of comparator and it's logic. Analog Comparator block diagram Registers ACSR (Analog Comparator Control and Status Register) is an 8-bit register which contains configuration bits for Analog Comparator. ACSR (Analog Comparator Control and Status Register) ACIS0, ACIS1 (Analog Comparator Inter
