I am having one more problem now...
I am using this below java file to create a database and table on the click event of Create DB Button( till here it is working fine) and then below this Create DB button, there is one more button named Send Button... and on the click event of Send Button I am opening another activity which contains a edit text and a button called Insert(this is also working fine for me) and on the click event of this Insert Button... I have to insert the value that we are typing into edit text box into the table that we have created previously.... but I am not able to figure it out why it is not inserting into table that we have created previously... what wrong I am doing please let me know.... Below are the codes....
