Android Audio Manager is a class in Android that helps you to implement the above-stated functionalities. So first, you need to create an Android Audio Manager class object and then use the setRingerMode() method.<\/p>\n
So, now let\u2019s see an example of the same.<\/p>\n
For creating the Audio Manager object, we need to use the getSystemService() method.<\/p>\n
Code:<\/strong><\/p>\n Now set the setRingerMode() as follows:<\/p>\n Code:<\/strong><\/p>\n So, as discussed earlier, you can have several ringing modes for your device. Now for this, you need to use the modes present in Audio Manager.<\/p>\n RINGER_MODE_NORMAL \u2013 It sets the device in its normal state of ringing. When activated, the device will play ringtones and notifications at the volume level set by the user. This is the default mode for most devices and is used when the user wants to hear audible alerts.<\/p>\n RINGER_MODE_VIBRATE<\/strong> \u2013 This mode sets the device to vibrate without playing any sound. The device will vibrate for incoming calls and notifications, making it suitable for environments where loud ringtones might be disruptive. This mode is often used in meetings or quiet places.<\/p>\n RINGER_MODE_SILENT \u2013<\/strong> This mode silences all ringtones and notifications. No sound or vibration is produced, ensuring complete discretion.<\/p>\n Till now, you just got to know about setRingerMode(), but there are more methods present. Let\u2019s see each of them below.<\/p>\n It displays the device’s current ringing mode. It returns one of the three modes: RINGER_MODE_NORMAL, RINGER_MODE_VIBRATE, or RINGER_MODE_SILENT. This helps you understand whether the device will ring, vibrate, or remain silent when there is an incoming call or notification.<\/p>\n It tells us the current audio mode of the device, such as MODE_NORMAL, MODE_RINGTONE, MODE_IN_CALL, or MODE_IN_COMMUNICATION. Knowing the audio mode is useful for managing audio settings and behaviours during different scenarios, like phone calls or media playback.<\/p>\n This method returns the current volume index for a particular audio stream in your device. For instance, it can give you the current volume level of the media, ringtone, or notification stream. It helps in understanding and adjusting the current audio levels for different types of audio outputs.<\/p>\n This method provides the maximum volume index a particular audio stream can have. This is useful for setting volume levels programmatically, ensuring you don’t exceed the maximum allowable volume for any stream type.<\/p>\n You can adjust your device\u2019s volume using this method. The direction parameter can be ADJUST_RAISE, ADJUST_LOWER, or ADJUST_SAME, and the flags parameter can specify additional behaviour, such as showing a volume UI. This allows for dynamic volume control based on user interactions or specific app requirements.<\/p>\n It is used to check if your device is playing a piece of music or not. It returns true if music is playing and false otherwise. This is particularly useful for applications that need to manage audio playback or interruptions, ensuring a smooth user experience.<\/p>\n As you know about Audio Manager, it\u2019s time for us to explore Android Auto Capture. Android Auto capture is beneficial in terms of communication.<\/p>\n Any android comes with an inbuilt microphone to support calls, conversations, and recording. These all features are possible only due to the Audio capture.<\/p>\n Now to implement the Audio capture, we use the MediaRecorder class. The MediaRecorder class helps us to record both audio as well as video.<\/p>\n To use the MediaRecorder class, you need to use the object of the class. After the object is created successfully, you can specify the source, file format, and output file.<\/p>\n Below is an example that will guide you through the process of implementing Audio Capture.<\/p>\n Code:<\/strong><\/p>\n Similar to Audio Manager, Audio capture also has many methods involved in it. You already saw that the start() method is used to start the recording, but now let\u2019s see some more practical methods.<\/p>\n It is used to stop the ongoing recording.<\/p>\n Whenever we need a recorder instance, we use the release() method.<\/p>\n It prepares the recorder before the actual recording begins.<\/p>\n It sets the source microphone from where the recording will occur.<\/p>\n It specifies the source from where the video will be recorded.<\/p>\n It specifies the format we want our audio file to be.<\/p>\n It sets the encoding format for the audio.<\/p>\n It specifies the path where we want our output file to be.<\/p>\n So, now let\u2019s see how you can implement AudioManager in your android application. We will develop an app to change your ringing modes and view the current mode. Now, let\u2019s see steps of how you need to build such a kind of application.<\/p>\n 1:<\/strong> Open your Android Studio and create a new Project.<\/p>\n 2:<\/strong> Select an empty activity and proceed.<\/p>\n 3:<\/strong> Provide a name to your application and then select API level 22 and proceed.<\/p>\n 4:<\/strong> From Android Marshmallow, you need to give access to do not disturb mode. To this, you need to add the below permission in your manifest file. After you successfully add this permission then only you can change the ringing modes.<\/p>\n Code: AndoridManifest.xml<\/strong><\/p>\n Step 5:<\/strong> Now, you need to create four buttons. Three to access the various ringing modes and one to display the current mode. Paste the below code in your activity_main.xml file and then proceed.<\/p>\n Code: activity_main.xml<\/strong><\/p>\n Step 6:<\/strong> Now, go to your MainActivity.kt file and paste the below code there.<\/p>\n Code: MainActivity.kt<\/strong><\/p>\n So, after you are done with the above steps, simply run your application and notice the following as output.<\/p>\n First, since my android version is above Marshmallow, I need to allow the Do Not Disturb mode in my application.<\/p>\n Now open your application again.<\/p>\n Next, check your current mode.<\/p>\n Now test switching between the three different modes and check if they are working.<\/p>\nlateinit var my_audio_manager:AudioManager\r\n\/\/creating an instance of the Audio Manager class\r\nmy_audio_manager = getSystemService(Context.AUDIO_SERVICE) as AudioManager\r\n<\/pre>\n
