项目中遇到这样的需求，要求监听耳机插拔状态变化，进行埋点上报处理，把实现代码分享一下。

public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();
    private boolean isHeadsetOn;
    private boolean isRegisteredAudioReceiver = false;
    private BroadcastReceiver INSTANCE;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    protected void onResume() {
        super.onResume();
        isHeadsetOn = getAudioState();
        Log.d(TAG, "[ouyangyj] isHeadsetOn = " + isHeadsetOn);
        registerAudioReceiver();
    }

    @Override
    protected void onPause() {
        super.onPause();
        unregisterAudioReceiver();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
    }

    private boolean getAudioState(){
        AudioManager audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
        return audioManager.isWiredHeadsetOn();
    }

    private void registerAudioReceiver(){
        Log.d(TAG, "[ouyangyj] registerAudioReceiver");
        if(INSTANCE==null){
            INSTANCE = new HeadSetPlugListenner();
        }

        IntentFilter filter = new IntentFilter();
        filter.addAction("android.intent.action.HEADSET_PLUG");
        // 或者使用Intent.ACTION_HEADSET_PLUG
        if(INSTANCE!=null && !isRegisteredAudioReceiver){
            try{
                registerReceiver(INSTANCE, filter);
                isRegisteredAudioReceiver = true;
            }catch (Throwable throwable){
                Log.d(TAG, "[ouyangyj] register audio receiver error!" + throwable);
            }
        }
    }

    private void unregisterAudioReceiver(){
        Log.d(TAG, "[ouyangyj] unregisterAudioReceiver");
        //使用完毕后，取消注册
        if(INSTANCE!=null && isRegisteredAudioReceiver){
            try{
                unregisterReceiver(INSTANCE);
                isRegisteredAudioReceiver = false;
            }catch (Throwable throwable){
                Log.d(TAG, "[ouyangyj] unregister audio receiver error!" + throwable);
            }
        }
    }

    class HeadSetPlugListenner extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.hasExtra("state")) {
                if (intent.getIntExtra("state", 2) == 0){
                    Log.d(TAG, "[ouyangyj] 耳机拔出");
                    //拔出
                }else if (intent.getIntExtra("state", 2) == 1) {
                    //插入
                    Log.d(TAG, "[ouyangyj] 耳机插入");
                }
            }
        }
    }
}

注意点：1、在AndroidManifest.xml文件中添加权限

          <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

2、注册和解注册的位置，根据实际情况做处理，防止内存泄露。
