I want to search a db and toast a specific column on the startup of the phone. The app keeps crashing and getting an exception even though I feel as the code is correct.
@Override
public void onReceive(Context ctx, Intent intent) {
Log.d("omg", "1");
DBAdapter do = new DBAdapter(ctx);
Log.d("omg", "2");
Cursor cursor = do.fetchAllItems();
Log.d("omg", "3");
if (cursor.moveToFirst()) {
Log.d("omg", "4");
do {
Log.d("omg", "5");
String title = cursor.getString(cursor.getColumnIndex("item"));
Log.d("omg", "6");
// i = cursor.getInt(cursor.getColumnIndex("id"));
Toast.makeText(ctx, title, Toast.LENGTH_LONG).show();
} while (cursor.moveToNext());
}
cursor.close();
}
The frustrating part is that I don't see any of my "omg" logs show up in logcat. I only see when my application crashes.
I get three lines of errors in logcat.

For anyone interested, here is my DBAdapter fetchAllItems code:
public Cursor fetchAllItems() {
return mDb.query(DATABASE_TABLE, new String[] { KEY_ITEM, KEY_PRIORITY,
KEY_ROWID }, null, null, null, null, null);
}
