Emulator over gRPC Examples

Thanks to Erwin Jansen for these samples and this readme. (I just formatted this and threw it in a gist to make it more shareable and readable)

Samples can be downloaded here: https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android/android-grpc/docs/grpc-samples

Caveats: Experimental feature!!

This is currently an experimental feature, and as such there are some things lacking that might be important if you want to use this in production:

A mind dump of resources for learning Android Development

Brief Overview

I learned from a combination video tutorials (CasterIO) , online classes (Udacity) , blogs (medium posts) , forums (/r/androiddev) , and the developer.android documentation, codelabs, and javadocs. Also, I follow anyone I learned from on Twitter so I could get more insight into the android ecosystem. I got a copy of the Android Big Nerd Ranch book but I’m not much of a book person when I’m on my computer, I mostly just google and SO stuff instead.

Udacity Courses

I got my start learning through Udacity’s courses which were made in partnership with Google

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

1. List All System Images Available for Download: sdkmanager --list | grep system-images

2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"

Context

Reverse Proxy?

• Node and Apache are not mutually exclusive. Apache (or NGINX if preferred) can be set up as a reverse-proxy for the Node server. This means that requests would go to Apache first, then forwarded on to the Node server.
  • Reasoning for this can be found: https://linuxtogether.org/configuring-reverse-proxy-for-node-using-apache-mod-proxy/

Or just use Node

• We had the opportunity of setting up a fresh Digital Ocean server running CentOS 7, and opt'd for this for simplicity and for the fun experience of learning how to set up a fresh CentOS 7 Server to be used with the MERN stack.
• In our scenario, Node can listen on port 80 and we should be good to go...

C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.

Git cheat list

• specifying revisions: http://schacon.github.io/git/git-rev-parse.html#_specifying_revisions

• list of all affected files both tracked/untracked (for automation)

  git status --porcelain
  

• name of the current banch and nothing else (for automation)
