Starting Android development on my phone

I have been creating blog posts from my phone and doing a little coding.  I have been wondering, though, if I could do android app development work on my phone.  I want to do this for the same reasons that I post to this blog from my phone.  With young kids and other responsibilities I don't have much time to sit in front of a computer.

So using what I had learned from blogging and other activities on my phone I decided to give it a try.

First I needed to learn how to build my apps from the command line.  I have done all my previous Android development using Eclipse.  The machine I am working on is running Ubuntu.  I did some reading and found out it was pretty easy.

First off, in the project folder I needed to be able to run the android command to setup the project.  To do that I had to add the android sdk directory to my path.  After doing that I got an error about tools.jar missing.  After some Googling and trying different things I ended up installing openjdk 7.  This resolved the issue.  Then I also needed to install ant.  I had no issues with that.

After that setup I ran the android command in the project folder passing some arguments specifying a target and some other things.  I already had some emulators setup from my previous development work, so I was able to use one of those as the target.

Then all I had to do was run 'ant clean' and then 'ant debug' and it created an apk for me.

Now I needed to be able to do that from my phone.  I setup ssh on the Ubuntu machine and I was able to connect from my phone using the ssh client app that I use.  The one I use now is just called SSH Client.

Then I setup the project as a github repository.  Using an app called SGit I am able to check out the repository on my phone and make changes to the code using an app called Quoda.  Then I commit and push the changes.  Then I ssh to the Ubuntu machine, run 'git pull', 'ant debug', and a new apk is generated.  The folder where it is generated is in my Dropbox folder, so then from my phone I can download it in the Dropbox app.

There are a lot of apps involved there and it takes a long time to get anything done.  This works okay, but I would like to cut out some of this process and maybe automate some things.  I will blog again after I look into some ways of automatically building the apk etc.

This post has been mostly written for a while, but I forgot to publish.  I am almost finished with a followup post.  I may publish that today as well.

Getting Hidden App Data From Your Google Drive

Some Android applications use space on your Google Drive to store data.  You can't see this data by browsing drive the normal way.  You can get access to it if you get the access token from the app and do a few other things.

I use an app to keep some notes and other things.  They require getting the paid version of the app to backup your data.  I wanted to see if I could get it myself without paying for the app.  I found out how to do this from this Stackoverflow post  The example there uses php. Since I have been learning Python recently, I decided to see if I could do the same thing with Python.

 There is a pretty good explanation of why you need to go through all the steps you need to go through to get your data in the accepted answer for that post, so I won't go into too much detail about that here.

My First Memories of Coding

The first time I remember writing code was in grade school in the computer lab.  We were learning Basic.  I'm not sure how old I was, but it would have been sometime in the late '80s or early '90s.  I remember they had us write a program that would take some numbers from the user and print out the average.  I had to ask how to do division. I had only seen it with the standard division symbol in math class, not the forward slash.  Soon after that I was able to get Basic on my home PC.  Actually I think it was included in MS-DOS.

At school and in the beginning at home I was using Basic where you had to use line numbers to write your code.  Then to edit a line you had to retype that line with the number.  Soon after that I was able to get QBasic and a book to help me get started.

Python control of Broadlink RM2 wifi remote

I recently got a Broadlink wifi remote.  I have been playing around trying to send commands to it with python.  I found code on github that does most of what I need.  It looks like the device itself doesn't learn any remote codes.  It is all in the app.  The code I found can send codes to the device and get codes from learning mode. I have a bunch of buttons programmed in the app already.  I wanted to see if I could get those codes.  I think I got them today.  The app, called eControls, allows you to backup your setup.  Today I was able to get my backup file from their backup site. Tomorrow I will try to use the codes from the backup.
