Android Sqlite Crud And Listview - Android Studio Tutorial

      DESCRIPTION      

✔Enter data(Text , Image) in SQLite
✔Read data(Text , Image) from SQLite in Custom ListView
✔Custom obrolan to update record
✔Update data(Text , Image) by onLongClicking the row of ListView
✔Delete data(Text , Image) by onLongClicking the row of ListView
✔Select Image from gallery using Library , crop/rotate image.

Step 1: Create a new project OR Open your project

Step 2: Create New Activity File>New>Activity>EmptyActivity

Step 3: Add following libraries in build.gradle(Module:app) 

implementation 'com.android.support:design:27.1.0' /*cardview library for our row.xml*/ implementation 'com.android.support:cardview-v7:27.1.0' /*image choosing/cropping library*/ implementation 'com.theartofdev.edmodo:android-image-cropper:2.6.+'

Step 4: Code
