You can use SQL transactions in Android like this. It's better to insert multiple rows into the database in larger batches then making single commit (write into SQLlite datafile which is very slow) for every inserted row.

public void insert(List students)
{
    SQLiteDatabase db = sh.getWritableDatabase();
    ContentValues cv = new ContentValues();

    db.beginTransaction();

    try {
        for (Student s : students) {
            cv.put(StudentHelper.FIRSTNAME,s.getFirstName());
            cv.put(StudentHelper.LASTNAME,s.getLastName());
            cv.put(StudentHelper.ADDRESS,s.getAddress());
            cv.put(StudentHelper.GPA,s.getGpa());

            db.insertOrThrow(StudentHelper.TABLE_NAME, null, cv)
        }
        db.setTransactionSuccessful();
    } finally {
        db.endTransaction();
    }
}
