Re: [android-developers] SQLite DB location on Windows PC
If you are running the app on the emulator it is stored within the filesystem that is stored within the emulator device image. If you are running the app on a physical device it is in fact stored on the device at the location you have shown.

Not sure what you are asking... you have listed the correct path to your database files... So, unless you can be more clear, you have answered your own question...

[android-developers] SQLite db shared between activities
Hello! I'm curious why the SQLite db requires a Context object, and what I should do to share the same instance of a db object between many activities? Should I initialize it in the first activity and use it across the application, or may be any activity should reinitialize the db with itself as db context? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] SQLite db shared between activities
I agree with Kostya. I used singleton pattern in my application. Initialize instance of db class in subclass of Application.Now i can use same object through out application.

[android-developers] sqlite db readonly when setting uses-sdk android:minSdkVersion=8 /
Hi All, I have run into a weird issue. I work with a database located on / sdcard/ and for some reason whenever I add uses-sdk android:minSdkVersion=8 / to the manifest sqlite opens the db as read only. It gets a bit weirder too. The below code opens the db and checks if the db is readonly, which returns false: db = SQLiteDatabase.openDatabase(/sdcard/test.db3, null, SQLiteDatabase.OPEN_READWRITE); Log.i(LOGTAG, Database status: + db.isReadOnly()); but if I try to write any data it bombs with: INFO/Database(6576): sqlite returned: error code = 8, msg = prepared statement aborts at 24: [INSERT INTO tags(type_id , tag) VALUES(?, ?);] ERROR/Database(6576): Error inserting type_id =1 tag=TestTag ERROR/Database(6576): android.database.sqlite.SQLiteException: error code 8: attempt to write a readonly database If I remove the uses-sdk tag from manifest everything works fine. I verified this behavior on the emulator and NexusOne running 2.2.1. Is this a known issue? Is there a workaround? Any help will be greatly appreciated.

[android-developers] SQLite DB, Cursors, CursorIndexOutOfBoundsException problems!! Help!
Hi all,
I just wrote my own DbAdapter by modifying the example DbAdapter in
Notepad tutorial. The problem came when I tried to fetch data from the
Database using my DbAdapter. I got :
android.database.CursorIndexOutOfBoundsException: Index -1 requested,
with a size of 1. Below is a snippet of my code that I was trying to
play around with the DB:
//rep,index are both some random integers that
I'm trying to store in a row
ex_rowId = mDbHelper.createExSet(rep, index,
1);
if(D) Log.d(TAG, rowid that was used for insertion:
+ ex_rowId);
Cursor c = mDbHelper.fetchExRow(ex_rowId);
if(c == null)
Log.d(TAG, HOLY-cursor null);
//a cursor's lifecycle is automatically taken care of
startManagingCursor(c);
int repIndex =
c.getColumnIndex(BtDbAdapter.KEY_EX_REP);
if(D)
{
Log.d(TAG,HOLY-column rep index: +repIndex);
Log.d(TAG,HOLY_column count:
+c.getColumnCount()+
row count: +c.getCount());
}
int i=0;
for(;ic.getColumnCount();i++)
{
Log.d(TAG,Column names:
+c.getColumnName(i).toString());
}
int repCount = c.getInt(repIndex);
if(D) Log.d(TAG, HOLY-rep count: +repCount);
In summary, the code above first creates a new row, which stores some
values into a row. Then it fetches the same row by using the returned
row id. At last I am trying to retrieve the values from the cursor.
Below is the debug print log:

[android-developers] SQlite DB
Hi All, I have been working on one application where it has to access the number of missed calls. i am facing the problem that the before the database of missed call get updated, the DB getting accessed so getting the old value. I am setting one Listener that will be called when the call ends, and i am reading the DB but still the DB has not yet upadated. Some times the DB is getting updated before i read the value but sometime not. Please post solution. Is there anything like i can wait till the DB update. Or just the delay kind of thing, i can give before reading the DB. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] SQLite db issue : no such column
Hi all, just to start I'm working on my application for the android
challenge for 2 months. Tutorial has been done successfully and
another thing I'm a C/C++ developper.
I'm stuck with this issue for 1 week, I have done many thing but I
can't find the error ! Maybe the error is so big that I can't see it,
well if someone see ;)
Here is my code :
public static final String KEY_NAME = name;
public static final String KEY_TYPE = type;
public static final String KEY_FILTER = rfilter;
public static final String KEY_ROWID= _id;
private static final String DATABASE_CREATE1 =
create table things (_id integer primary key autoincrement,
+ name text not null, type integer not null, rfilter
integer not null);;
private static final String DATABASE_NAME = data;
private static final String DATABASE_TABLE = things;
private static final int DATABASE_VERSION = 2;
private SQLiteDatabase mDb;
private final Context mCtx;
public ThingDbAdapter(Context ctx) {
this.mCtx = ctx;
}
public ThingDbAdapter open() throws SQLException {
try {
mDb = mCtx.openDatabase(DATABASE_NAME, null);
} catch (FileNotFoundException e) {
try {
mDb = mCtx.createDatabase(DATABASE_NAME,
DATABASE_VERSION, 0, null);
mDb.execSQL(DATABASE_CREATE1);
} catch (FileNotFoundException e1) {
throw new SQLException(Could not create database);
}
}
return this;
}
public void close() {
mDb.close();
}
public long createNote(String name, int type, int rfilter) {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_NAME, name);
initialValues.put(KEY_TYPE, type);
initialValues.put(KEY_FILTER, rfilter);
return mDb.insert(DATABASE_TABLE, null, initialValues);
}
public boolean deleteNote(long rowId) {
return mDb.delete(DATABASE_TABLE, KEY_ROWID + = + rowId,
null) 0;
}
public Cursor fetchAllNotes() {
return mDb.query(DATABASE_TABLE, new String[] {
KEY_ROWID, KEY_NAME, KEY_TYPE, KEY_FILTER}, null,
null, null, null, null);
}
public Cursor fetchNote(long rowId) throws SQLException {
Cursor result = mDb.query(true, DATABASE_TABLE, new String[] {
KEY_ROWID, KEY_NAME, KEY_TYPE, KEY_FILTER}, KEY_ROWID
+ = + rowId, null, null,
null, null);
if ((result.count() == 0) || !result.first()) {
throw new SQLException(No note matching ID: + rowId);
}
return result;
}
public boolean updateNote(long rowId, String name, int type, int
rfilter) {
ContentValues args = new ContentValues();
args.put(KEY_NAME, name);
args.put(KEY_TYPE, type);
args.put(KEY_FILTER, rfilter);
return mDb.update(DATABASE_TABLE, args, KEY_ROWID + = +
rowId, null) 0;
}
As you can see I respect totaly the Notepad tutorial. And I'm having
this error :
SQLException no such column rfilter.
Why is the rfilter column missing. I have created this column
previously !!
Please help a desperate C/C++ programmer :)
Kind Regards,
Olivier K.
