Let us discuss these two topics one by one.<\/p>\n
Android Audio Manager<\/h2>\n
Audio Manager in general plays and controls the volume and ring of a device. Audio Manager in android is a class that provides access to the volume and modes of the device. Android audio manager helps us adjust the volume and ringing modes of devices based on our requirements. The modes that are well known to us, that are Ringing, Vibration, Loud, Silent, etc. Android provides us with AudioManager class to provide control for them.<\/p>\n
Here, to make use of the AndroidManager<\/strong> class, we will first create its object. After we create an object, we can use setRingerMode<\/strong>.<\/p>\n To create its object, we will call the getSystemService()<\/strong> method as follows:<\/p>\n To setRingerMode<\/strong> we will follow the following syntax:<\/p>\n This method takes three types of parameters for each mode, the three modes are:<\/p>\n There are some more methods apart from setRingerMode<\/strong>, that we are enlisting below:<\/p>\n Now that, we have seen the AudioManager class of Android. We will proceed to learn Audio Capture.<\/p>\n So, Android<\/a> comes with a built-in microphone through which we communicate over our phone. This microphone can help us capture audio, store it and play it in our devices. We do it with the help of the MediaRecorder<\/strong> class. This class is used to record Audio as well as Video in Android devices. To use this class, we need to create an object of this class. And after creating the object we would need to set the source, format and output file. To create the object and set the source and all, we will do the following:<\/p>\n After we are done with it, we can start the recording using:<\/p>\n Apart from the start()<\/strong> method, there are some other methods of MediaRecorder<\/strong> class that are: Any doubts in DataFlair’s Android audio manager article till now? Ask in the comment section.<\/em><\/p>\n Now we will implement AudioManger in our application<\/strong><\/em><\/a> as follows:<\/p>\n Step 1:<\/strong> First of all we will create a new project and name it MyAudioManager<\/strong>.<\/p>\n After that, we will open the activity_main.xml<\/strong> file and write the code below:<\/p>\n Step 2:<\/strong> Now we will write the code for MainActivity.java<\/strong> as follows:<\/p>\n Step 3:<\/strong> since we have different color themes, we will now set the color values in color.xml<\/strong>. Open res\/values\/color.xml and write the code below:<\/p>\n Step 4:<\/strong> After writing the code, we will run it, and the following will come:<\/p>\n These will be the three modes:<\/p>\n i) General Mode<\/strong> ii) Silent Mode<\/strong>Private AudioManager myAM;\r\nmyAM = (AudioManager)getSystemService(Context.AUDIO_SERVICE);<\/pre>\n
myAudioManager.serRingerMode(AudioManager.RINGER_MODE_SILENT);<\/pre>\n
