How to Check available space on Android devices using Kotlin?

Kotlin AndroidApps/ApplicationsMobile Development

This example demonstrates how to Check available space on Android devices using Kotlin.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_marginTop="50dp"
      android:text="Tutorials Point"
      android:textAlignment="center"
      android:textColor="@android:color/holo_green_dark"
      android:textSize="32sp"
      android:textStyle="bold" />
   <TextView
      android:id="@+id/textView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_centerInParent="true"
      android:textAlignment="center"
      android:textSize="24sp"
      android:textStyle="bold" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.kt

import android.os.Bundle
import android.os.Environment
import android.os.StatFs
import android.text.format.Formatter
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
import java.io.File
class MainActivity : AppCompatActivity() {
   override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)
      title = "KotlinApp"
      val textView: TextView = findViewById(R.id.textView)
      val stat = StatFs(Environment.getExternalStorageDirectory().path)
      val bytesAvailable = stat.blockSize.toLong() * stat.blockCount.toLong()
      val megAvailable = bytesAvailable / 1048576
      val path: File = Environment.getDataDirectory()
      val stat2 = StatFs(path.path)
      val blockSize = stat2.blockSize.toLong()
      val availableBlocks = stat2.availableBlocks.toLong()
      val format: String = Formatter.formatFileSize(this, availableBlocks * blockSize)
      textView.text = String.format("Available Memory: %s", format)
   }
}

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.q11">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run Play Icon icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
