According to my application i create the database with two tables. when i inserting the data in 1 table then it runs correctly after that when i save data in the second table then it gives the exception of illegal state exception (database cannot be open). Please give me the solution.
Im doing an app which uses sqlite db file in assets folder, There is a screen in my app having a button 'check for update'. Client has given me an URL link to update db file(which gives a sqlite file). When user clicks on the button i need to upgrade the old db file with new db file from URL.
I have seen other posts similar to this one but none of the solutions listed work for me. When I use the following command: adb pull /data/data/com.mydomain.myappname/databases/MyDatabase.db / home/me the following error results. failed to copy '/data/data/com.mydomain.myappname/databases/ MyDatabase.db' to '/home/me/MyDatabase.db': Permission denied I have no problems with the emulator. I am using a Dev Phone 2.
Well I updated with the official 2.1 but behold when i try to load joeys recovery it refuses to open the bin file. I want to install a custom rom built from his site to remove all the bloat and install live wallpaper etc. I have been reading for 2 hours and I can't find a fix. I even tried downloading an older version of swupgrade.
All of the tickets are electronic tickets (pdf) saved in my gmail, and I thought I would be able to open up the files and just let them scan my phone. Yet when I tried to open the file, it pulled up the PDF viewer app and then told me it wasn't able to open it. Why is this? I also just tried saving the attachment to my sd card from the gmail app and open it from there, but I couldn't figure out how to save an attachment from an email to my phone. Any help here would be great.
I have a ListActivity that uses a CursorAdapter to fill the rows in the view. I wrote a database helper class that gives me back results for common queries I make for my app, and it uses an SQLiteOpenHelper implementation I wrote to open the database. I use the open helper to open the database and get a cursor to pass to my CursorAdapter.
Here's a code snippet:
The problem I'm having, that I didn't have before I implemented the open helper (before I just opened the database directly without a helper), is when I click on an item, which takes me to another activity, and then go back to this activity. When it initializes everything is fine, and my list is populated fine, but when I go back from the activity that follows, the list is empty and in the LogCat I see "Invalid statement in fillWindow()".
It appears from a few post I've seen that the reason is, when I requery the cursor, the database is closed. But I'm not closing it! I'm scratching my head on this one.
I am getting an error from Logcat saying that a certain column (in my SQLiteOpenHelper subclass) does not exist. I thought I could upgrade the database by changing the DATABASE_CREATE string. But apparently not, so how can I (step-by-step) upgrade my SQLite Database from version 1 to version 2? I apologize if the question seems "noobish", but I am still learning about Android. @Pentium10 This is what I do in onUpgrade:
How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.
To create/open a database instead of making use of the SQLiteOpenHelper (because I want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, I am getting this exception for that line of code:

Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am I just using SQLiteDatabase.openDatabase the wrong way?) Would it help if I create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that I passed in?) If creating the file manually is the way to go, is it just an empty file, or do I have to write something to it?
I'm a novice user writing my first android application. I have the need to upload a file to a webserver from the device. I googled enough before joining this forum and not at one place did I find a suitable solution. I would like to know how to launch the file browser when user clicks on the "Browse" button to upload a file.
When I create a instance of the SQLiteOpenHelper, I always need a "Context" to be passed as its constructor's argument. To use this "Context", in my service layer class, I extends Activity class, though I do not display this activity on the screen because it is my service layer. I always get NullPointer exception when I open the SQLiteOpenHelper in my service layer class, Is it because my service layer class extends the Activity class but I did not show this activity on mobile screen? (That's there is no intent to my service layer class), if it is so, how to get rid of it if I wanna open a SQLiteOpenHelper in my service layer class which do not need to extends Activity, but need a Context object to pass to SQLiteOpenHelper?
I have a paid app on the market. -I uploaded an upgrade -The market download manager hangs on 'Starting Download' when I try to download the newest version. Has anyone experienced this? (If the problem is resolved shortly, I'll post here.)
I have recently updated my HTC One to 4.2.2 but since doing this my gallery doesn't open up on the tiles page now, it just goes straight to the albums page, so no highlights etc. Is it an option that got reset?
While iterating through my contacts database, the first Name (GIVEN_NAME) always returns an integer while the last Name (FAMILY_NAME) always returns null. I am running on HTC Incredible. What am I doing wrong? Code...
I have been trying to update from 1.6 to 2.1 these last few days. Depending on the USB port I either get an error when PC Companion, or Update Service is in the preparation stage, something like: All components needed to continue could not be found. Or I get to the stage when you turn off the phone and restart it with the backbutton pressed which leads to XP wanting to find drivers for SEMC usb flash. By looking through other communities I found those drivers could be found in: C:Program Files (x86)Sony EricssonUpdate ServicesetupdriversUSBFlashDriver.zip. I could initually install those to one USB port, but when trying to download the update through Update Service I get yet another error that the task could not be completed.
No matter what I do I am unable to open a file, either in my app's data directory or on the sdcard and also in a folder on the sdcard. To test I placed a test.txt file in all three directories.When I do listfiles, I get the correct list of files set in an array. I've even tried getting the list and filtering out a specific file and try opening it that way and just trying the first item in the array. Is there some security that may be set that is making it so I cant open files? This is not the emulator, it is on a device.
I need to somehow backup my applitcations database to a file so that it can later be retored using that file. The only way I would do it would be by reading every table to an xml ffile but it seems soo ineficient. The data does not have to be humand readable.
Is it possible to take a csv file stored in the res/raw resource directory and use it to populate a table in the sqlite3 database? My thought was that, if there was a way to do a bulk import for the entire file into the table then that would be cleaner and faster than iterating over each line in the file and executing individual insert statements...
but I'm having trouble applying those statements in my Android application. My first thought was to try something like the following...but no luck:
Using Local XML file as a database for a android app?
I am trying to build a app with flash using a xml file as database, to read the xml from a external file from the local directory isn't a problem, the problem is how to write data from flash to the xml file.
