[android-developers] android database connectivity problem
Hi,
I am trying to do a database connectivity in my android emulator, the
problem is i am doing a servlet program that includes a sqlite
connectivity in it.
After compiling the java files,generating the classes.dex, I am adding
META-INF and classes.dex into a classes.zip file with the respective
jars in the lib directory.Later a war file is generated from (WEB-
INF,META-INF,index.html the database file).The war is then uploaded.
But when i download the war file and run it from the i-jetty server, I
am getting the following error: org.sqlite.jdbc
java.lang.ClassNotFound Exeption.
The jars have been uploaded in the android emulator by an application
written in an activity class along with the respective database i am
trying to work on.
It is working properly on the Jetty server with the class paths set
with the jars and classes,but not on the I-Jetty server in the phone.
Eventually the I-Jetty server is able to run all servlet programs that
doesn't include a database connectivity.
I have tried to do the database connectivity with hsqldb database but
the result is the same.
I have been trying for days but couldn't get this database
connectivity from my android emulator working, Could anyone please
help me, Here is my code,
try{
out.println(html+
head+
titleDataBase/title+
/head+
body+
h1DataBase tbl_countries : /h1);
Class.forName(org.sqlite.JDBC);
//Class.forName(SQLite.JDBCDriver).newInstance();
Connection conn
=DriverManager.getConnection(jdbc:sqlite:webapps/DbTest/
TestData.db);
Statement stat=conn.createStatement();
stat.executeUpdate(drop table if exists tbl_countries;);
stat.executeUpdate(create table tbl_countries (id INTEGER
PRIMARY KEY AUTOINCREMENT, country_name TEXT););
PreparedStatement prep = conn.prepareStatement(insert into
tbl_countries(country_name) values (?););
prep.setString(1, Australia);
prep.addBatch();
prep.setString(1, Srilanka);
prep.addBatch();
prep.setString(1, USA);
prep.addBatch();
conn.setAutoCommit(false);
prep.executeBatch();
conn.setAutoCommit(true);
out.println(table border=1);
out.println(tr);
out.println(thbid/b/th);
out.println(thbcountry_name/b/th);
out.println(/tr);
ResultSet rs = stat.executeQuery(select * from
tbl_countries;);
while (rs.next())
{
out.println(tr);
out.println(td+rs.getString(id)+/
td);
out.println(td+rs.getString(country_name)+/td);
out.println(/tr);
}
rs.close();
conn.close();
}
catch(Exception e)
{
out.println(h2+e.getMessage()+/h2);
String str=e.toString();
out.println(h2+str+/h2);
}
out.println(/table/body/html);
}
Thanks,
Ritam Roy Choudhury

[android-developers] Android Database Example Error
I am not sure where to send this but I was hoping someone in this group could help me. I was looking at this example http://developer.android.com/guide/topics/data/data-storage.html#db. If you look at the constructor it is named different than the class. I assume this is a bug unless I am missing something. I thought that I would point this out so that it can be fixed if need be to avoid any confusion for future developers. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Android Database and PC Applications
Hi all, I am currently doing some research on a program that I would like to develop for the Android platform. The android device will store information for the program using the internal SQLite3 Database. I also would like to to develop a program in either C# or Java (preferably C#) that will synchronise the data between the android and the PC. The idea is that the PC application will get the data out of the SQLite3 Database. How can I get a PC application ideally in C# to be able to get the information out of the android device, is there a way that I can use the ADB without having to have the Android SDK installed on the PC. Another way I was thinking is that the PC application runs a service that I develop on the Android platform that exports the database into a CSV file to be stored on the SD card, however, I am still going to need to use ADB to get the data in order to avoid the user having to put the phone into Disk Drive instead of Sync Mode.
