While we run application on devices, how do we compare application version will support running device os version or not. To compare app version to device version we should know what is the current device version on programmatically. To get current device version we will use android Build.VERSION class which contains properties like SDK_INT, RELEASE name...
In this below example code we will learn how to get device SDK Version and API details
Let get started
1. Create android application in android studio
2. In this example we have two widgets Button and TextView, On tap on button we will write code for get SDK version details and add them to TextView.
Let update xml file with below code
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".SDkVersion">
<TextView
android:id="@+id/txt_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginBottom="50dp"
android:text=""
android:textAlignment="center"
android:textColor="@android:color/holo_green_dark"
android:textSize="32sp"
android:textStyle="bold"
app:layout_constraintBottom_toTopOf="@+id/button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Info"
android:onClick="getInfo"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

3. Write code to get device sdk and API details on button click
Update activity with below code
package rrtutors.com.androidtopactivity
import android.os.Build
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import android.widget.TextView
class SDkVersion : AppCompatActivity() {
lateinit var txt_info:TextView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_sdk_version)
txt_info=findViewById(R.id.txt_info)
}
fun getInfo(view: View) {
val versionAPI = Build.VERSION.SDK_INT
val versionRelease = Build.VERSION.RELEASE
txt_info.text = "API Version : $versionAPI\nVersion Release : $versionRelease"
}
}
|
4. Run application on your device/emulator. On Button click you will get the current device api version
