Here we are accessing a mysql database and get the table values and show it in the Android side as tables.
These are some tutorials that I have posted on connection with php and getting tablevalues.
1. Android phpmySQL connection redone.
Here we have 3 classes
1. GetDataFromDB.java – Gets value from DB in the form of JSON.
2. Users.java _ Class which holds the one row table object.
3. MainActivity.java _ Which implements these classes and show the tables.
