Description

Summary: Drakma Require Crashes Android Example App

Steps to Reproduce:

1) Successfully install and run Android app without Drakma;
2) Install Drakma Dependencies and link:
2a)http://weitz.de/drakma/#install
http://common-lisp.net/projects/usocket/releases/
http://weitz.de/flexi-streams/
http://weitz.de/chunga/
http://www.cliki.net/cl-base64
http://www.cliki.net/puri
https://github.com/edicl/cl-ppcre.git
git://gitorious.org/trivial-gray-streams/trivial-gray-streams.git

The only .asd I didn't link is cl-ppcre-unicode.asd; I did link cl-ppcre.asd

3) uncomment this code in app.lisp:
  (pushnew :drakma-no-ssl *features*)
  (require :drakma)
4) mocl --android LispContacts app.lisp
5) cd LispContacts/jni && ndkbuild

6) Run||Debug the app in ADK on a Nexus 7
7) App starts, then crashes with:
Fatal signal 11 (SIGSEGV) at 0xdeadbaas (code=1), thread 28736 (le.lispcontacts)

Approach 2, MOCL Repl

mocl repl --android /tmp
This repl is an experimental work in progress. See documentation for further
details. You can quit this repl via (rt:quit).

* (pushnew :drakma-no-ssl *features*)

(:DRAKMA-NO-SSL :MOCL :ASDF2 :ASDF :ANSI-CL :COMMON-LISP :LITTLE-ENDIAN :ARM
 :ANDROID :LINUX :UNIX)
* (require :drakma)

NIL
* (print (drakma:http-request "http://wukix.com"))
Warning: Compile-time evaluation failed at RT::TYPEP-CLASS.

NIL

Expected Results:

App doesn't crash; REPL successfully completes request;

Actual Results:

App Crashes when Drakma is (require)'d; REPL fails with compile time error;

Notes:

So yea, has anyone gotten Drakma to work on Android?

Comments

Drakma has worked in the past on Android. What is your Android version? I will try to reproduce it.

4.3 on a Note 3 and 4.3.1 on a Nexus 7.

Thanks for taking a look.

It looks like mocl is having some weird issue with the latest version of trivial gray streams. In the meantime you can use this previous version:

https://git.gitorious.org/trivial-gray-streams/wukix-trivial-gray-streams.git

That should fix the main issue here.

Other than that, please be aware of the following:
1) wukix.com now redirects all HTTP requests to HTTPS, which conflicts with the :drakma-no-ssl requirement. Do your drakma requests against something that accepts HTTP, e.g. http://cliki.net (works for me)
2) Android applications that use networking functions will need the permission "android.permission.INTERNET" added to the app manifest (AndroidManifest.xml). Please make sure you have this or drakma requests will not work.

Edit:

The above URL is the git url for cloning, the gitorious page itself is at https://gitorious.org/trivial-gray-streams/wukix-trivial-gray-streams

Awesome, that seems to have fixed the issue for me. Thanks.
