Can I access android MediaProvider (Images & Videos) databases directly from my code rather then through a content provider ?
I'm planning to have my own Cursor implementation so inside it I want to access the media databases directly, possible or android does not allow it ?

Just found out that I don't need content providers if I don't need to share data with other applications. But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.
View 2 Replies View RelatedI understand, at least on paper, the basic difference between the Content Provider and just directly accessing the SQLiteDatabase. I have a functioning prototype for my application, and currently it is just directly hitting the database. I don't really have any experience using the Content Provider pattern, but I have found out that I will need to share some data with another application.
I will only be sharing about 2 out of a dozen or so tables, so I was wondering if I should be just completely redoing the data layer to follow the Content Provider pattern, or just expose only those tables via a Content Provider for the sake of the other application and still directly access the database in the primary application.
One of the issues I ran into with my prototype was that I have some fairly complex transactions, and the code I wrote to get that working is not designed particularly well and isn't reusable at all. As I add more functionality to this app, I'm going to need a better designed data access layer, before I set off writing my own, does anyone know of any good resources with design patterns for this type of thing already? Also, if I need to go the Content Provider route, am I going to have solid control over the database transactions?
Does anyone know of a direct api that allows access to CPU usage statistics for different applications/tasks running inside android? All I can find is data available by accessing a file "/proc/stat" but this seems a little cumbersome. ActivityManager holds data about processes/tasks etc but no CPU usage stats.

View 4 Replies View Relatedinformation on direct access to GEARS geolocation functions from an Android application. To date, I have not found any. geolocation includes three Android-specific public Java classes, AndroidGpsLocationProvider, AndroidRadioLocationProvider, and AndroidWifiLocationProvider. The fact that they are Android-specific and that they are public lead me to conclude that I should be able to use these classes in my application. However, not surprisingly, when I try to access these classes, my application fails (see log below) because, among other things, I have no way to correctly identify nativeObject in the java classes. At the very least, I would like to understand the purpose of the three Android-specific public Java classes, and how we should use them.

View 4 Replies View RelatedI've just published an app to Google Play. It is an app that allows people (mostly tourists) in my area to easily find businesses around them. One functionality that my app offers is to make a phone call to these companies by tapping a button in the app, including emergency numbers.
Google Play says that the app requires "direct phone access, it can call phone numbers without your intervention, which can lead to a high phone bill, but not emergency numbers". This doesn't completely fit my intention.
My app would work just fine if it had to ask the user every time it wanted to make a call, and it doesn't call anything when no buttons are tapped, plus I DO want the app to be able to call emergency numbers (with the user's consent off course).

I work on a cruise ship and we're continually crossing time zones. Currently, to alter the time zone on my (rooted) HTC OneX, I need to pull down the notifications tray, select settings, scroll down and select date and time, then select time zone. I can't use the Auto function, as the network time on the ship (satellite) is only available over Wi-Fi, for which I have to pay an exorbitant rate.
I'm looking for an app that will allow me one-tap access to changing the time zone. 'Time Zone Widget Light' almost does the job, as a tap on the widget scrolls through pre-set time zones, but this only allows me to step forward, and sometimes I need to go backwards as well (sadly our ship itineraries refuse to follow pre-set time zones, although I'm working on it!)

I am using the following versions - android sdk1.1 and sqlite 3.0.
I would like to ask you smart people if anyone has seen any documentation regarding web access to a database from within an Android application. I would like to create a (FREE) application where the users can share information (rants/complains) around the globe. Each user will be able to see a little globe in his phone with locations of other users and some specific information about them.
Architecturally, I am thinking "database in my GoDaddy host, exposing a web service", and the web service accessed from the Android application. But I see no documentation about accessing web services. I can also go XML, maybe, but I am not seeing what mechanisms exist in the Android for over-the-web XML access.
I have a feeling I am mis-understanding something big in the picture. Can someone point me to docs, or knows something about this topic? (the iPhone has a Lighter app where you can see people lighting around the globe. Mine is similar, but people would not be lighting, instead they will be "complaining/ranting").
I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods:
Method 1:I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth.
Method 2:I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects.
My questions are:
Which method is faster?
Which method is easier on the phone's battery?

I'm creating a Thread and in that thread I open a database connection using the DBHelper, perform an update on a field in my database and close it. I create a separate one in the Thread because if the View is closed the global one for that view is closed, causing my Thread update to throw an error. The thread is in a View, that also has it's own instance of the DBHelper and opens the database onCreate closes it onPause opens it onResume closes it onDestroy The instance in my Thread is throwing this but not all the time :error code 5: database is locked Is there a known practice I should implement so I don't get this error?
View 9 Replies View RelatedI have different background threads in my application, one doing periodical database updates, another responsible for doing long searches and so. Obviously some are just reading from database while others are writing as well. Once in a while I get "database is locked" exception. I need to know the safe way of reading/writing from/to database on different threads. As well I've found "isDbLockedByCurrentThread()" and "isDbLockedByOtherThreads()" methods on SQLiteDatabase. Should I use them every time I want to access the database? What if the database is locked? Should I pause the current thread and retry a few milliseconds later?
View 5 Replies View RelatedI am creating an android app that is basically a listing of information on Mushrooms. I get this information from an sqlite database. I have a global singleton with a services class inside it in which I use to access my db. Almost every activity accesses the db. Is it better to leave my db open all the time or open and close it as I need the data? If the best practice is to leave it open all the time, where do I need to make sure to close it and what is the worst case scenario if I left it open when the activity was destroyed?

View 3 Replies View RelatedI have four tabs (reports, review reports, map and settings). I have an sqlite database populated with report information. I wish to have the database accessible throughout the application. The reports tab successfully adds data to the database however using the same methodology crashes the application.

In the reports tab the following code is used to launch the database...

In the onCreate() method of the Review Tab - Where I wish to review reports - I try to access to the database through the call calling the return report method

View 2 Replies View RelatedI am adding a local database as a cache to a remote web service in my android application to answer queries. I used ArrayAdapters before for list views to display the results from the web service. Now with a database cache, the result could be either a Cursor(from database) or a List(from web), which means the adapter can be CursorAdapter or ArrayAdapter too. Creating two adapters for one query doesn't seem to be a good idea. So I am wondering what would be the best way to refactor my current code to add this database feature?
