Android :: Attempts To Save Data In Database Aren't Working
Nov 5, 2010
We've been developing an Android app at work for a few months now and recently acquired Droid Incredibles (API ver. 8) to replace our HTC Dev Phones (API ver. 4).
DANG are these some sweet new toys, but unsurprisingly, they've got a few quirks...
1) It's normal for my user to let the program run for long periods without any input, but he'd still need the display to work the entire time. Can anybody suggest a function call or setting or something that will prevent the Incredible's screen from dimming while my application is running??
2) On the Dev phone, I was able to copy my application's database file (thousands of uses, that) onto the SD card's root directory and fly. I could view the directory on my PC via USB; when I released the SD card from the PC, my application was perfectly happy with it and obediently read from and wrote to the database; and I didn't have to remove the SD card, ever. That doesn't seem to be the case with the newer, better phone, though. My application seems to be reading my start up parameters properly, but all attempts to save data in my database aren't working so well unless I'm just doing something wrong. Can anybody point me to documentation specifically geared toward the Incredible?

On my motorola droid and other andriod devices there is a known issue where if you enter too many incorrect pattern attempts it ask's for your google email/password but doesnt accept it. Even though its the correct password, the only fix is a hard reset. Is that bug still around on the incredible or has google fixed it?

In an HTML page, I have at one place, <a name="updates"></a>, but in a WebView, when I click on <a href="#updates">updates</a>, it doesn't jump to the correct place. It works fine if I load that page in a browser. It does nothing but mark that link as visited in the WebView. Is there some setting that I'm not correctly configuring?

My friendstream and facebook app aren't working. Whenever I open friendstream it loads for a minute or two and then just tells me I have to force close it. And as for facebook the actual app works, but when I try to use the widget it tells me problem loading gadget. But if I delete it, reinstall it, and don't download the update it works fine. Is this just me or is it a problem with the app?

So I'm trying to make Google play music save on my sdcard and I'm having a problem with the script. First the phone I have is the DROID RAZR MAXX and I just did a FDR because of a root problem and now that I have it rooted the scripts aren't working. My script text is this
"Mount -o bind sdcard-ext/MusicCache sdcard/Android/data/com.google.Android.music"
The error it shows is like this:
exec sh '/mnt/sdcard/MusicScript.txt'
card/MusicScript.txt'
/mnt/sdcard/MusicScript.txt[2]: Mount: not found

Recently my Eclipse IDE seems it has stopped letting me use the common shortcuts like Ctrl + Shift + O and it is not prompting me with suggestions when I hover my mouse over an error.

I have a samsung galaxy grand and I so like it but I am quite disappointed as some of its features aren't working. For instance, the automatic feature for making calls. The instruction says that if you put the device on your ear, it will automatically prompt you to contacts where you can make calls.

I have a activity with 3 imagesViews and a Button. Clicking on the ImageView shows an AlertDialog with a list of images (located in /res/drawable) that the user can select. I've hit a wall where I don't know how to store the images to the database that were selected in the ImageViews.

I have just started on a new application that will use SQLite for persistance and Im a bit confused over the usage of a context when utilizing the SQLiteOpenHelper.
I have a base class called Storable, which my models extend if they need to be persisted. i had intended to use a synchronized singleton database adapter, but I can't for the life of me understand how to utilize the SQLiteOpenHelper as it requires a context, which my models don't appear to possess.
I'm aware that I can get around this by not using the SQLOpenHelper - but if this restriction is in place, I would assume its to prevent people creating apps "the wrong way" for android.
What is the best practice way for saving models in the database?

In my android application,I want to save some photos uploaded from a server on my database and then reuse them later. I think I should save them in a binary format and save their links into the database. Is it the better solution? Can you give some code or an example? now I only uploaded the image and display it directly using an ImageView but I want to make it available in my application when the user is offline.

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done? (I'm trying to create a leader board or global scoreboard for my Android game on my server.)

I created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

I am experiencing a problem where when the android device wake up from sleep, the Activity would take forever to get redrawn(and have to terminate it most of the time). I am not sure why, but when I comment out the code below where it retrieves an object from the database based on id stored in the bundle, the problem goes away.
Not sure why the db transaction is causing an issue.
secondly, is it better to store the object in bundle instead of storing its id and retrieving it from db in onCreate?
CODE:...............

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.
this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

I am currently looking in to developing an application for the android platform. I have some information that is stored within the SQLite Database of Android.
What I want to be able to do is to perform a query to the database table and populate a TableLayout with the information from the database table.
I have tried to find this on the Internet but have not had much luck. If anyone can help me to get about doing this would be great.

I am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.
1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.

I am trying to design a sqlite database that will store notes. Each of these notes will have common fields like title, due date, details, priority, and completed.
In addition though, I would like to add data for more specialized notes like price for shopping list items and author/publisher data for books.
I also want to have a few general purpose fields that users can fill with whatever text data they want. How can I design my database table in this case?
I could just have a field for each piece of data for every note, but that would waste a lot of fields and I'd like to have other options and suggestions.
