Sideload Android OTA Update Using ADB

Pre-Work

  1. Make sure you backup any personal data such as photos before applying update.
  2. Get the latest adb tool from the Android SDK Platform-Tools package.
  3. Add adb to your PATH environment variable or, as the instructions below assume, change into the directory containing the executable.
  4. Enable USB debugging for your device as described here.

On Machine

  1. Change into the directory containing the adb executable.
  2. Download the latest OTA image (appropriate for your device) from https://developers.google.com/android/ota into the adb directory.

Summary of 'Clean code' by Robert C. Martin

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.


General rules

  1. Follow standard conventions.
  2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
  3. Boy scout rule. Leave the campground cleaner than you found it.
  4. Always find root cause. Always look for the root cause of a problem.

Design rules

// Three mostly separate examples: Adding, reading/listening, and removing multiple items from firebase
// Firebase V3.0.0
// one school has many courses and many studens
// one course has many students and is in only one school
// one student is in many courses and only one school
const db = firebase.database().ref('test');
const userId = firebase.auth().currentUser.uid;
