Hi,

Problem in showing progress bar while executing insert statement in android. While
calling this try block its showing blank screen. Not even xml is called while executing this statement.

try {
    while ((str = in.readLine()) != null) {
    try {                           
         db.execSQL(str);                   
    } catch (Exception e) {

    }
}   

Thanks,
