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?

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?
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?
View 1 Replies View RelatedToday, the focus of a cell phone's capabilities is drifting away from plain making a phone call.
And somehow, this shows in the API's too. Therefor I'm wondering: if I want to write an app that e.g. pitches up, records, scrambles... an incoming call - you know, the voice on the other side -, what aspect of the API should I use?
I looked into Android, into Windows Phone, iPhone... (briefly), but had no luck. Is this just unintended usage?
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?

View 4 Replies View RelatedDoes 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.

View 1 Replies View RelatedI 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?
View 2 Replies View RelatedMy application needs to perform some activities in background (like interacting with the network and check the location and some other stuff), having or not the main activity visible. Which is the best way to achieve this? Should I write a service for each kind of job? Or just one service that performs everything? I am aware that I will need to launch threads / asynctasks in any case because the service runs on the same thread of the UI, but maybe having several services is a more clear and readable structure.

View 3 Replies View RelatedI'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.

View 1 Replies View RelatedI am creating an app which allows for many different Activities to be started from a TabActivity(up to ~25). Most of the activities require data from the sqlite database, so when onCreate is run, an AsyncTask creates an SQLiteOpenHelper object(which will open a readable/writable database), runs a query, data is retrieved, and everything is then closed.
I was just testing messing around to see if i could break something, so i added every Activityto the TabActivity's TabHost. I then started mashing each tab as quickly as possible.
I noticed that very quickly i began to see in the LogCat: Caused by: android.database.sqlite.SQLiteException: database is locked: BEGIN EXCLUSIVE; and the app proceeded to die.
Typically there will only be about 4-6 tabs(i can just limit the user anyway) for the TabHost. I haven't been able to break anything with a small amount of tabs to mash, but i am still worried that maybe i am accessing the database in a poor way.
How can i prevent my SQLiteDatabase objects to cause a lock?
If i create a ContentProvider will that eliminate the possibility of database locking?
Do you have any suggestions for changes I could make for accessing data from an SQLiteDatabase?
I ended up taking the approach of using the Application class and storing 1 SQLiteOpenHelper and trying my best to keep it synchronized. This seems to be working great - i put all my 25 activities in the TabHost and mashed away on them with no errors.
I am calling ((SQLiteDbApplication)getApplication()).setDbHelper(new DBHelper(this, Constants.DB_NAME, null, Constants.DB_VERSION_CODE)); method(shown below) in every onCreate() in my activities
Any further suggestions to this approach or to the changes i made using this Application class?

I'll come up with any excuse to get a chance to write my first Android application. I've never done much with it except for a couple of tutorials.
I've got a Windows application that controls a device, and the computer isn't necessarily right next to it. I think it would be great to be able to use my Droid to issue the device commands, but I'm not sure where exactly to start. I don't have a problem writing the GUI code or Java required to send commands to the PC, but it's the wireless connection to the PC that I don't know how to approach.
Bluetooth seems like a good choice. I have a USB-Bluetooth adapter, but no Bluetooth API on Windows. Can anyone suggest one? From reading other questions here on SO, it sounds like the 2.0 SDK has some sort of Bluetooth API, so that's good.
Another option is to use 802.11, and then write a web page / service that would allow the phone to issue commands to the device.
