Make sure the cursor is initialized correctly before accessing data from it.

Question

Problem :

I am trying to get the data from my DB.

My code fails on below line:

list[p] = cImage.getString(i);

The error message is as below:

11-27 12:34:59.683: E/CursorWindow(6901): Failed to read row 2, column 0 from a CursorWindow which has 2 rows, 2 columns.
11-27 12:34:59.683: D/AndroidRuntime(6901): Shutting down VM

11-27 12:34:59.693: E/AndroidRuntime(6901):     at android.app.ActivityThread.handleCreateService(ActivityThread.java:2667)

For my call log:

Log.i("image length", list[p].length()+"");

I get few calls before my code breaks. The problem seems to happen only for some of the rows but a error code does not tell me what a problem is

Answer 1

In my case the error was because I didn't include a column in a projection passed into a CursorLoader constructor. Which means I was trying to access the data from the column that didn't exist in my cursor that was returned.

It worked for me.

OR

Try calling the cursor.moveToFirst () before using a cursor. Let me know if that worked.
