Today, 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'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?

View 1 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 2 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?
CODE:...................
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.
