Android: Documentation improvement for fresh starters #116

Open dagosi opened 5 years ago

dagosi commented 5 years ago

I recently started using RubyMotion, and it was't as easy as the documentation stated. I had to make use of the Slack channel to ask for help, and Amir jumped to the rescue.

I was getting this error:

clang: error: no such file or directory: './build/Development-23/obj/local/x86/Users/daniel/code/motion/Hello/app/main_activity.rb.x86.o.s'

Tasks: TOP => build
(See full trace by running task with --trace)

As you can see, it does not say very well what the issue was (well... a non-existent directory/file, but why?) Not to mentioned that I followed step by step the tutorial on the website.

After battling with Amir on this, he pointed something very interesting out. It seems that the Indie plan on includes the 27 API. This is something that the documentation does not explicitly say, which led me to waste a couple of hours of my time.

Also, I noticed that some other new developers are having the same issue about this. Would be better to have a more detail documentation on this step.

Because Amir was really helpful with me setting things up, I would like help with this if necessary. Please let me know.

I am also discovering RubyMotion, but with an old project I'm picking up and trying to build, and the error messages were not very clear too:

Tasks: TOP => build

I have now understood a few things thanks to @amirrajan šŸ˜„

First, I had to bump the api_version to one that is actually supported by rubymotion (22 here)

Also, the building step causing problems was the loading of lib jars, so I removed them from the Rakefile:

# -*- coding: utf-8 -*-
$:.unshift("/Library/RubyMotion/lib")
require 'motion/project/template/android'

begin
  require 'bundler'
  Bundler.require
rescue LoadError
end

Motion::Project::App.setup do |app|
  app.name = 'My app'
  app.package = 'com.my.app'
  app.icon = 'logo_icon'
  app.api_version = '22'

# I commented out those:
  app.vendor_project jar: 'vendor/android-support-v4.jar'
  app.vendor_project jar: 'vendor/android-pdfview-1.0.2.jar', native: ["vendor/x86/libvudroid.so", "vendor/armeabi-v7a/libvudroid.so"]
  app.vendor_project jar: 'vendor/volley.jar'
  app.vendor_project jar: 'vendor/httpcore-4.3.3.jar'
  app.vendor_project jar: 'vendor/httpmime-4.3.6.jar'

 # ....

end

Now I have to understand how to load them an other way or to replace their usage by native calls.

At some point, the build was stuck because I had no emulator running (I thought I had typed rake device) but it would be more clear to show a "no emulator" message.

The last thing I still don't understand is the Could not find rake-10.4.2 in any of the sources but it doesn't seem to have any impact on rake actually running šŸ˜…

Here is something @wndxlori typed up I grabbed in the slack channel awhile ago. I am on a new computer so I will edit when I reinstall Andriod. Just dropping this here in the meantime.

That setup was for RailsConf 2017. It was still working early 2018, but Iā€™m certain needs updates now.
