Android :: Scripting Environment For Application - No Way Of Accomplishing
Oct 13, 2009
I'm trying to make my app scriptable. Specifically, I need to expose a few Java APIs and make callbacks settable via user-written scripts. Ideally I'd like to hide some of the complexity away in a DSL, but there's no way of accomplishing what I want neatly without some form of user scripting, so I may accept another alternative if it meets my requirements. Initially I looked into Scala as that is my main language of choice, but the Scala interpreter is just a wrapper around its compiler, which I'm told won't run well if at all on the phone.
I've also tried JRuby, which worked under Cupcake. There appears to be a regression in the form of a Dalvik bug that prevents it from working under Donut, however:

I've also seen the Android Scripting Environment. Am I correct in assuming that this only supports running full interpreters and not embedding scripting languages into apps?

I'd like to use python scripts as plugins for an app I'm developing. This seems to be possible by interacting with android-scripting-environment (ASE), as is done by Locale, but I haven't found any documentation about this. How you execute ASE scripts from your own app?

Downloaded ASE from Google code, and was looking through tutorials, and available scripts. I found a script I wanted to try, however copy pasting it is removing all whitespace (and this is a Python script. Is there a simple way to download a script from the Internet into the Android Scripting Environment?

I've been quietly lurking around, enjoying my simple 2.2 leak Droid X. But, I've always known that eventually I want to root it and install ROMs and themes and whatnot. The problem is, I don't know the correct sequence of hacks/mods to get to my desired end product. I also don't know what the current best method is for accomplishing each part of the sequence. My desired end product would be something like a rooted Droid X with Vanilla Froyo and flyX and whatever other speed tweaks are available. I'd also like to keep my apps and settings that I have now, if that's possible. What I'm asking for is a simple list of things to do to get to that end product. I don't need the detail of how to do each one, I can figure that out myself (of course, if you want to provide links, that's be appreciated too).

I am searching for some method of extending Android application with scripting support. All I need is something similar to Lua's C api - I should be able to bind a few functions (classes not necessary) and run a script with a parameter to do some actions and produce result. Android api bindings are unnecessary (even unwanted for security reasons). I have searched this group and google for a lib like this, but no success. Sure there is Android Scripting Environment, but it runs Lua and Python normal interpreter as a separate C process. The Java port of Lua interpreter, which I could possibly compile for Android, doesn't seem to be ready yet, but I may be wrong. I have also looked at JRuby, which looks good except it is large and it may be hard to limit script's access to Java classes, or to set it up properly. Also, Android seems to have some Javascript interpreter (with Webkit) - maybe there is a way to use it inside app? So here is my question: How can I add scripting to my app?

Hey I've been playing with my droid and I was wonder whether there are any scripting apps. Something like python on the phone? Is it possible? Is there anything like that?

Does anyone know of a web browser app, or a script for a web browser, that would allow an Android user to update all four of the windows in the web browser (from a pre-configured list of URLs) with a single input to the smartphone? With such an app, one could update four pages in the background, where 3G or "Edge" network speed would not be very important, and then. later on, quickly view/review all four web pages once the time-consuming data fill was complete. My job situation does not allow me to pull out the smartphone and play with it for several minutes to do this -- I could however start the process then come back in a few minutes and quickly toggle through four-screens of already loaded web info.

I have an XML based file format that I'm using to store and load instances of objects. I'm interested in adding some scripting support to those objects so that they can respond to events. That said, I also don't want to cripple performance. Are there any well known scripting options for Android - maybe even ones where while loading, I can pre-compile and cache the scripts?

I have some knowledge about Human computer interaction and some basic knowledge programming scripts (Python) that run from start to finish and automate some tasks I want to do or calculations. In the past I built interfaces in HTML with PHP behind it. I would like my python scripts to evolve from the command line and build some applications with GUIs that would allow the user to drag files and push buttons to initiate operations and check progress graphically. Since I write my scripts in Python I looked at some of the options (Tkinter, wxPython, PyQt) but I can't make a decision between them to invest my time learn one and not the other. My criteria: Has a introduction for programmers for GUI (what are the differences from a script, examples of some simple interfaces). A framework that would allow me to run my programs on the platforms I use most (Windows) but that can also run on Mac and maybe Linux, without too much modification. If not the same, similar to how you program GUI for Android and/or Nokia smartphones. I'm planning to write some programs for these platforms in the near future so I would like to carry over some of the lessons here onto those platforms, if possible. I did find this previous question but none of the answers are satisfactory. Does any of the frameworks fit these requirements better than the others or are they essentially similar and I would be happy with any of them?

I've got an iphone app and I'm looking to port some of the data-layer objective-c code to a scripting language which can also run on an android phone. Any suggestions on what to use? I'd also like to be able to push new scripts to the app for bug fixes. Not sure if this is against the iphone SDK agreement or not.

I read an article from the web on SL4A (which is also known as Android Scripting Environment). The site from where i got an article is: http://infoworld.com/d/developer-world/php-development-comes-google-android-652. But i got the theoretical knowledge only for SL4A (ASE). Anybody having practical idea or practical example, pleas suggest to me. Which are the scripting language supported by ASE? How do i download script?

I'm looking into a solution that needs apps to be dynamically extensible. One way could be an extension language or scripting engine. I've seen the Android Scripting Environment, but this needs the actual C scripting engine (Python or Lua) running as a separate process. I would like the runtime to be a Java app itself, like JavaScript using Rhino (and not using a WebView). Another way is to download Java code dynamically. But, Android does not support jar downloading and dynamic classloading, since these bytecode class files are not used directly.

I was just wondering if there was an Android environment that would let you run Android OS inside/alongside Windows, like Virtual PC basically, and let you have full connectivity just like if you were using your phone. I'm not sure what the utility could be right now but it sounds interesting to me.

I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
int a = 1 / 0;
}
Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

Reading the sensor API (http://developer.android.com/reference/android/ hardware/SensorManager.html) The section about ACCURACY speak about calibration:
"calibration with the environment is needed"
How do it calibrate?! Is this software calibration? Phone specific calibration??
I don't see any methods to calibrate.
Using the HTC Magic the compass often give me crazy values like if I was on the magnetic pole. I feel pretty scared and hide under a tinfoil hat just in case...
So any url, doc or explanation!

I would like to use self defined Environment variables in my source code.
I use System.getenv() to do this and the code line looks like this. Log.d("MyTest","== MyEnv " + System.getenv("AP") + " ANDROID_ASSETS:" + System.getenv("ANDROID_ASSETS"));
Before I execute my code I define my AP variable with export: export AP="12345" and the this is my output of set command
ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=9,32768
ANDROID_ROOT=/system
AP=12345
Then I execute my code and I get this line from logcat
D/MyTest( 5363): == MyEnv null ANDROID_ASSETS:/system/app
The value for my defined Environment variable is null. Any suggestions on why it didn't work?

i am trying to look into android goldfish code and probably make some changes in it. As it is a long way to go for me i am actually unable to decide the tools that i need to set up. I come from an IDE based programming experience so am always trying to find a walk through tutorial to get goldfish kernel code in eclipse CDT to browse and code but no luck.I have followed the post source.android.com/source/building-kernels.html and built the kernel accordingly.wiki.eclipse.org/HowTo_use_the_CDT_to_navigate_Linux_kernel_source but am still not confident of my setup.

i read kubuntu 11.10 finally has integrated phone capabilities and is going to be heavily geared towards mobile devices URL....and development of Android execution environment for the android os that allows you tu run .apk in linux if so i think this would be full of win for kubuntu with it being the first linux distro with integrated phone capabilities and if the AEE was available that would just be the coolest phone ever
