Return new Employee(Utility.getPhoto(blob), name, age) īefore inserting image and retrive image from SQLite Database we use these below methods. Int age = cur.getInt(cur.getColumnIndex(EMP_AGE)) String name = cur.getString(cur.getColumnIndex(EMP_NAME)) Public class InsertandRetriveBlobData extends Activity, null, null, null, null, null, null) īyte blob = cur.getBlob(cur.getColumnIndex(EMP_PHOTO)) To get all Name,Photo,Age we use Corresponding getXXX() methods.Īt the time of retriving photo we will get blob array of image.at that time we need to convert byte array to image.for that purpose we use getPhoto() method in Utility class which will convert our blob array into Bitmap image and retrun Bitmap image.Īndroid Activity(InsertandRetriveBlobData.java) RetriveEmpDetails() method which is retrieve Employee Details from Database and return Employee Object. You can view the database either through. ![]() we have created a login and signup page in android studio using java where we will save all the user information such as email and password in the SQLite database. The database we are using is SQLite that comes with android. In the file manager, you can check the database of the user which is in text file format. The Android SDK that we are going to use here is the set of development tools to develop applications for the android platform. In this article, we will look at an example to perform Login and Registration in Android using SQLite. Here we can see before inserting image into database,we should be convert your Bitmap image to byte array for that we are using Utility class getBytes()method. Login and Registration in Android and SQLite. param sleepAfterYieldDelay if > 0, sleep this long before starting a new transaction if. throw an exception if that is not the case. that there are no nested transactions (beginTransaction has only been called once) and will. InsertEmpDetails() method which is taken Employee Class as parameter and it store all Employee information into Employees Table. returns a new transaction will have been created but not marked as successful. Now modify the code in activitymain.xml as follows: 1. This will ensure that the Book table can be successfully created when the database is created. ![]() While retrieving that image you will get byte convert that byte to bitmap by which you will get original image. The execSQL () method of SQLiteDatabase is used to execute this table creation statement, and a Toast pops up to indicate that the creation is successful. Convert that image to byte array & store that byte to DB. Here we See One Example which is Store Employee Details Likeįor Employee Name we use text datatype and for Employee Age integer datatype.But to Store Employee Photo which datatype ? at that time we use BLOB datatype. To store any image in sqlite database you need to store that image in byte array instead of string. At that point of time in SQLite ( BLOB) type is prefer and this will be store binary data nothing but a byte array data.(Converting our image to byte array and store into SQLite) So many people are confuse which data type is best for insert large amount of data(like images) in to database.
