String selectQuery = "SELECT * FROM tableimage".ContentValues cv = new ContentValues()./*to write in a database call the getWritableDatabase method */.ByteArrayOutputStream bos = new ByteArrayOutputStream()./*create the object of ByteArrayoutputStream class. Now break the image into the byte parts by calling toByteArray() of ByteOutputStream class and store it in a array */.Find location and check all the tables and its fields using 'DB Browser. The package contains all the required APIs to use an SQLite database in our android applications. Bitmap b = codeResource(getResources(), R.drawable.image) Android tutorial to locate where your SQLite Database gets stored in Android Studio./* In this i have used BitMap class which is used to put the image in a variable. Bitmapfactory class is used to get the image from the drawable folder by calling decodeResource() method. */.tOnClickListener( new OnClickListener().Button button = (Button) findViewById(R.id.button).editText2 = (EditText) findViewById(R.id.editText2).editText1 = (EditText) findViewById(R.id.editText1).textView4 = (TextView) findViewById(R.id.textView4).textView3 = (TextView) findViewById(R.id.textView3).iv = (ImageView) findViewById(R.id.myimage).Below is the updated code for the DBHandler.java file after adding the above code snippet. In this, we are simply adding a new method for reading all the courses from the SQLite database. mdb = new MyDataBase(getApplicationContext(), "imagedata", null, 1 ) Navigate to the app > java > your app’s package name > DBHandler and add the below code to it./*Create the database by calling and ing all the parameters to the constructor of MyDataBase class*/.setContentView(R.layout.activity_main).public void onCreate(Bundle savedInstanceState)./** Called when the activity is first created. */.import java.io.File import java.io.FileOutputStream import java.io.IOException import java.io.InputStream import java.io. public class MainActivity extends Activity If you are having pre built data base than copy it in asset folder and create an new class as DataBaseHelper which implements SQLiteOpenHelper Than use following code.The first thing we must do is logically create our database For this, a Helper class is used in which we define the structure of our database the tables, data types, and primary keys are defined in this Helper made with Kotlin as the programming language: class ListSQLiteHelper(įactory: SQLiteDatabase. Examples of creating a SQLite database in Android This is where the database comes in to store information locally on Android currently the database that Android supports is called SQLite and essentially it is a small file that contains all the data of our application, which we register to be more precise We can make queries as if it were a relational database, because it is a full-fledged database and in this post we will talk about how to use this database in our Android applications. Using SQLite database to store data locally SQLite is a lightweight and open database engine, whose main attraction is that we can easily and securely keep user or application data in a very small file and that differs from other systems such as MySQL in that it does not require the support of a server, it does not require port configuration support and so on and everything, but everything is stored in a single and simple file that is our database and it is open source therefore, you will see it in multiple applications that are not Android only with Android Studio or other similar IDEs. to the user in an organized way of course, for this it is necessary to have a connection to the Internet, or at least to the Intranet if this connection is lost then the application would be unusable since it would not be able to fetch the information and present it to the user. In modern times we have seen how all applications today connect to an external API, server, essentially an external agent to bring data and present it. Databases are an essential tool to keep user data and the application in general safe, organized and accessible at all times this last point is essential and is to be able to access the saved data at all times.
