Aug 18, 2010

I have an minor issue when taking a photo. I have a button that invokes the camera, successfully takes a photo, and returns to my entry form. My only problem is the database leak that occurs when pressing the button to call the camera.

General :: Google Voice - Multiple Threads For Same Contact Created

Jul 21, 2012

I recently returned to android. I was hoping this issue with google voice had been worked out, especially as I am about to do a full convert/port to google voice.

So the same contact will text me but often times google voice will create multiple threads making it very annoying to sift through them on the Voice SMS Inbox. It does this also on my browser window. Its not 100% of the time, but almost seems like if its a text on another day, another thread is made. Is there a way to fix this or merge the threads under the same contact?

Android :: Multiple Successive Queries To A Database

Apr 10, 2009

Has anyone other than me needed to make consecutive queries to a sqlitedatabase? My application works sometimes but other times (about 98% of the time), the app will crash. What I'm doing is using the sqlitedatabase.query(..) to return a cursor which I parse, I make multiple successive queries to the database and parse different recordsets/cursors.

My question would be does a sqlitedatabase need to recover or clean up after a .query is issued?

Android :: Android - Accessing Single Database From Multiple Activities In Application

Dec 15, 2009

I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different parts of the data in real time.

Currently, I have each activity open its own DBManager object (the helper class I created to manage the database). This is causing problems though and I would like a slightly more global access solution so I don't have to keep opening/closing/creating a database.

I'm considering several options, and would like to hear pros and cons of each as well as other suggestions.

Singleton style. Have a wrapper class that returns a reference to the only database manager so any activity that needs it can use it.

Static Manager. Have the manager class be entirely static members and have it open the database on load. Easily accessible by anyone that needs it (which is everyone).

Merger between 1 and 2. I could make a database manager class that initializes the member singleton instance of the database and all of the data manipulation methods were static. Then I wouldn't even need a reference to the singleton to access the database.

Android :: Sharing Sqlite Database Between Multiple Android Activities

Oct 12, 2009

Can two or more Android Activities open an sqlite3 database for write?

I have two Activities that need to insert data into the same sqlite database. When the second Activity calls SQLiteOpenHelper.getWriteableDatabase() an IllegalStateException is thrown with the message "SQLiteDatabase created and never closed".

I've been able to avoid the Exception by making my database object a singleton but I'm thinking there must be a better way.

Android :: Android ContentProvider Database Query Multiple Tables

May 7, 2010

I'm writing an RSS reader for Android. I've faced a certain difficulty which the problem I can't resolve since databases aren't my expertise.. So i figured out maybe one of you could help me out! I currently have 3 tables (Categories, links and feeds). My goal is too link a feed to multiple categories. Therefor I'm using a Link table. My databases is an Android ContentProvider (sqlite) and looks like the following:

| Categories | | Links | | Feeds |
|------------| |---------| |-------|
| _ID | | Category| | _ID |
| Title | | Feed | | Title |
| URL |

I currently wrote the following code in my FeedListActivity to retrieve a list of links and their feeds.

CODE:.................

Now my question:

I was wondering how I could optimize this database layout, code or query so I would get my entries in a more efficient way. Because i believe this link table or the query to retrieve links isn't needed! Or am i doing this the correct way?

Android :: Android - Inserting - Updating Multiple Records To SQL Database

Jun 24, 2010

I've just started working with SQL and Android and from what I can see, updates and inserts back to the database need to be handled individually?

I can retrieve a Cursor containing multiple records, but if I wanted to apply an update to each record in the cursor, I can only see how to do this individually, using ContentValues and Update(), and then the cursor requires reloading??

Same with if I wish to create multiple new records, these appear to be required to be inserted individually? Can I not create a List and bulk insert?

To me this seems slow and cumbersome, and there has to be something I'm not yet aware of (searching for answers is failing me... likely due to using incorrect terms being new to android/java)

Here's a very simple example of what I basically what I want to achieve, however there must be a better way to achieve this functionality. (I know there are some other bad practises in here, just creating a quick eample)

Android :: Android - Use One SQLiteOpenHelper Class For Multiple Database Files

Nov 20, 2010

My app uses two databases (separate files). To handle these databases I have created two Helper classes which extend SQLiteOpenHelper, one for each database.

I am now going to add a third database and wonder whether I need to create yet another Helper class (and if I used a 4th and a 5th database would I need even more Helper classes), or can I use the same Helper class for multiple databases?

The problem that I see with trying to use just one Helper class is that I can't see how to pass the name of the individual database files to the Helper. At present the name of the database is hard-coded as a Static field of each of the Helper classes, but if I had only one Helper class I would need to be able to pass the different names in to the Constructor when creating the separate Helper objects; the problem is that the SQLiteOpenHelper Constructor seems to be called by Android with just one parameter: the Context.

I'm new to Android programming, and I wanted to pull list options from a column of the SQLite database for the user to select. How would I go about doing this? Like, say the database table to be read is called countries, and the columns were ID, country, and capital. How would I let the user pick from the list of capitals and have the application return the information in that row?

Android :: Interacting With Remote Databases

Jun 9, 2009

Lets say Im creating an Android app for a company that already provides some sort of online service. I want my android app to extend this online service and I want the app to interact with my remote databases, would I embed a web browser in my application or directly connect to my remote database from within my code? If I am directly connected to a database from within code and not through a web browser, would that be a security risk since the connection info would be distributed in the code?

Android :: ADB Access To Application Databases Without Root

Jan 16, 2010

Can anyone tell me, is it possible to use the ADB to pull and push a database from an app, without root privileges on the phone? For example, I know the location on my rooted magic and dream is:
/data/data/com.xxxx.xxxx/databases/xxxx

I know that you can use ADB without root, but when trying to use the shell - you can't view that location without root privaliges. But I have been told you can use push and pull if you know the file you want? Basically I want to pull a database from MY app on a non rooted phone modify it and push it back on. Only trouble I have is, the two phones I have are both root and I don't have access to a non root one to try it out.
