PHP for Android: prototyping Android apps in php
Download as ODP, PDF4 likes6,312 views
The document discusses the use of PHP for developing Android applications, detailing methods to run PHP on Android through static compilation and linking to the Bionic library. It introduces SL4A (Scripting Layer for Android), which enables access to Android APIs via JSON RPC calls and provides examples of PHP scripts running on Android. Additionally, it mentions community involvement and resources for sharing scripts and development materials.

PHP for Android: prototyping Android apps in php
- 1. PHP for Android Prototyping Android apps in php Cesare D'Amico cesare@wyrd.it
- 2. Cesare D'Amico freelance php dev Hi, nice to meet you! cesare@wyrd.it Twitter: __ce (double underscore) http://cesaredami.co/
- 4. Genetically modified php :)
- 5. We're going to talk about... + PFAf SL4A
- 6. Android
- 7. Android • built on top of a linux kernel • native libc (Bionic): 0.5 * sizeof(GNU libC) • runtime (Dalvik VM) + system libs • application framework • Java!
- 8. How can we make php run on Android? 1. static compilation with Glibc (over 7MB)... fat! 2. linked to Bionic: smaller (~2MB), but tweaks needed
- 9. How can we make php run on Android? 3. SL4A to the rescue!
- 10. SL4A – scripting layer for Android • Google project, led by Damon Kohler • Open Source • exposes Android API • quite active
- 11. SL4A: installation As easy as: 1) enable “Unknown sources” under Applications settings 2)
- 12. PHP for Android project • led by Iván Mosquera, software engineer at Irontec (the people behind IronPython and other OS projects) • Open Source • Started in 2009 • php-for-android on Google Groups
- 13. PFA: installation The PFA apk just installs other components: • php_rX.zip: – php binary • php_scripts_rX.zip – scripts and PFAf • php_extras_rX.zip • Android.php + php.ini
- 15. SL4A: how does it work? Provides Android facades Makes the Android API available through JSON RPC calls
- 16. PFA: let's try it
- 17. PFA: let's try it <?php require_once('Android.php'); $droid = new Android(); $droid>vibrate();
- 18. PFA: let's try it SOOOO easy! :-)
- 19. PFA: let's try it Let's try something else:
- 20. PFA: let's try it <?php require_once('Android.php'); $droid = new Android(); $name = $droid>getInput('Hi!', 'What is your name?'); $droid>makeToast('Hello '. $name['result']);
- 21. PFA: let's try it
- 22. PFA: access phone features
- 23. PFA: access phone features <?php require_once('Android.php'); $droid = new Android(); $droid>viewContacts();
- 24. PFA: access phone features Many more features available; API full list: http://j.mp/9btqUG Examples: smsSend, sendEmail, cameraCapturePicture, viewHTML, bluetoothConnect, contactsGet, viewMap... (perhaps not *everything* available yet)
- 25. PFA: writing scripts Directly on the phone!
- 26. PFA: writing scripts SOOOOO slow and unusable! :-(
- 27. PFA: writing scripts Including local files: <?php include('/sdcard/proj/...'); ?>
- 29. PFA: including remote code <?php require_once('Android.php'); $droid = new Android(); include('http://www.wyrd.it/ droid.php.txt'); <?php $droid>makeToast("There's a starman waiting in the sky!"); remote.php droid.php.txt
- 30. PFA: including remote code
- 31. PFA: including remote code include('http://www.wyrd.it/ droid.php.txt'); Secure Handy ? This is here for testing purposes ONLY!
- 32. PFA: including remote code Don't forget that PFA, although yet useable in many respects, is still alpha software. In the future we'll be able to distribute scripts in apk format, without using allow_url_fopen
- 35. PFAf: PFA framework Base php class: ScriptAbstract; apps extend this class and implement init() States-based: put on a stack the next action you want to execute function currentAction(){ ... $this>setNextAction('next'); } function nextAction() { ... }
- 37. PFA wants you! You can help by writing scripts and sharing them: http://www.phpforandroid.net/scripts ...and there are good examples there! Take a look at the wi-fi scanner and the web server ;)
