AudioManager in Android with Example

  • Last Updated : 06 Sep, 2021

AudioManager is a class provided by Android which can be used to control the ringer volume of your Android device. With the help of this Audio Manager class, you can easily control the ringer volume of your device. Audio Manager Class can be used by calling the getSystemService() method in Android. When you create Audio Manager Class then you can use setRingerMode() method to change the ringer volume of your device. The setRingerMode() method takes an integer parameter to set the ringer profile of your device. There are three different integer parameters that need to be passed in setRingerMode() method are as follows: 

RINGER_MODE_NORMALThis mode will set your device mode to Normal/General mode.
RINGER_MODE_SILENTThis mode will set your device mode to Silent mode.
RINGER_MODE_VIBRATEThis mode will set your device mode to vibrate mode. 

Example

This is the Simple Example where we are creating Ringtone Manager App. This app will help you to change the current state of your device from General to Vibrate and then to Silent Mode. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.

Step 2: Add permissions in the AndroidManifest.xml file

Add below line in AndroidManifest.xml file. 

<uses-permission android:name=”android.permission.ACCESS_NOTIFICATION_POLICY” />

Step 3: Add google repository in the build.gradle file of the application project if by default it is not there

buildscript {

 repositories {

    google()

    mavenCentral()

}

All Jetpack components are available in the Google Maven repository, include them in the build.gradle file

allprojects {

 repositories {

    google()

   mavenCentral()

 }

}

Step 4: Modify the strings.xml file

Below is the code for the strings.xml file.

XML




<resources>
    <string name="app_name">GFG Ringtone Manager</string>
    <string name="vibrate_mode">vibrate_mode</string>
    <string name="silent_mode">silent_mode</string>
    <string name="ring_mode">ringtone_mode</string>
    <string name="welcome_to_ringtone_manager_app">Welcome to Ringtone Manager App</string>
    <string name="current_mode">Current Mode</string>
</resources>

Step 5: Working with the activity_main.xml file

Below is the code for the activity_main.xml file. Comments are added inside the code to understand the code in more detail.

XML




<?xml version="1.0" encoding="utf-8"?>
<!--XML Code for your activity_main.xml-->
<RelativeLayout
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
     
    <!-- Textview to display the heading of the app-->
    <TextView
        android:id="@+id/idTVHeading"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_marginTop="50dp"
        android:layout_marginRight="20dp"
        android:text="@string/welcome_to_ringtone_manager_app"
        android:textAlignment="center"
        android:textColor="@color/green"
        android:textSize="20sp" />
     
    <!-- Textview to display the current mode
         of the Ringer mode-->
    <TextView

        android:layout_marginTop="60dp"
        android:text="@string/current_mode"
        android:textAlignment="center"
        android:textAllCaps="true"
        android:textColor="@color/black"
        android:textSize="20sp"
        android:textStyle="bold" />
 
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/idTVCurrentMode"
        android:layout_marginTop="80dp"
        android:orientation="horizontal"
        android:weightSum="3">
         
        <!-- width of image button is 0dp because
             we have mentioned weight=1-->
        <!-- tint represents the color of icons
             of image button-->
        <!-- all icons of image button are placed
             in drawable folder-->
        <ImageButton
            android:id="@+id/idIBVibrateMode"
            android:layout_width="0dp"
            android:layout_height="100dp"
            android:layout_margin="10dp"
            android:layout_weight="1"
            android:background="@color/green"
            android:contentDescription="@string/vibrate_mode"
            android:src="@drawable/ic_vibrate"
            android:tint="@color/white" />
 
        <ImageButton
            android:id="@+id/idIBSilentMode"
            android:layout_width="0dp"
            android:layout_height="100dp"
            android:layout_margin="10dp"
            android:layout_weight="1"
            android:background="@color/green"
            android:contentDescription="@string/silent_mode"
            android:src="@drawable/ic_silent_mode"
            android:tint="@color/white" />
 
        <ImageButton
            android:id="@+id/idIBRingtoneMode"
            android:layout_width="0dp"
            android:layout_height="100dp"
            android:layout_margin="10dp"
            android:layout_weight="1"
            android:background="@color/green"
            android:contentDescription="@string/ring_mode"
            android:src="@drawable/ic_ringtone_mode"
            android:tint="@color/white" />
    </LinearLayout>
</RelativeLayout>

Step 6: Working with the MainActivity.java file 

Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

        // current mode will store current mode

        currentmode = audioManager.getRingerMode();
 
        switch (currentmode) {
            case AudioManager.RINGER_MODE_NORMAL:

            case AudioManager.RINGER_MODE_VIBRATE:
                currentStateTV.setText("Vibrate Mode");
            default:
                currentStateTV.setText("Fail to get mode");
        }
 
        silentIB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 
                // the below code is to check the permission that the access
                // notification policy settings from users device..
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !notificationManager.isNotificationPolicyAccessGranted()) {
                    Intent intent = new Intent(android.provider.Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
                    startActivity(intent);
                }
 
                // set ringer mode here will sets your ringer mode to silent mode
                audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                Toast.makeText(MainActivity.this, "Silent Mode Activated..", Toast.LENGTH_SHORT).show();
                currentStateTV.setText("Silent Mode Activated..");
            }
        });
 
        vibrateIB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // set ringer mode here will sets your ringer mode to vibrate mode
                audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
                Toast.makeText(MainActivity.this, "Vibrate Mode Activated..", Toast.LENGTH_SHORT).show();
                currentStateTV.setText("Vibrate Mode Activated..");
            }
        });
 
        ringtoneIB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // set ringer mode here will sets your ringer mode to normal mode
                audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
                Toast.makeText(MainActivity.this, "Ringtone Mode Activated..", Toast.LENGTH_SHORT).show();
                currentStateTV.setText("Ringtone Mode Activated..");
