How To Increase The Android APK Version Number In Android Studio

Problem :
While updating the android app in google play store I am seeing an error message as You need to use a different version code for your APK or Android App Bundle because you already have one with version code 1.

Solution : 

1) Open your android application in Android Studio .
2) Open build.gradle(Module: app)
3) Increase the version number and version name as shown in the below code
2) Go to Generate Signed Bundle Or APK  and choose APK option and finish .Your latest apk will be generated in \app\release folder in your local .

android {

compileSdkVersion 29    

buildToolsVersion "29.0.3"   

defaultConfig 

{

applicationId "com.app.digitalcashkourse"        

minSdkVersion 15        

targetSdkVersion 29        

versionCode 2

versionName "2.0"

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

}

buildTypes {

     release {
