Android devices can be connected to several different dock devices. These include car or home docks and digital and analog docks. Therefore, when the device dock changes, it throws the intentionACTION_DOCK_EVENT

If the device is connected, it can be docked in any of the four types of dock:

  • Car
  • Desktop
  • Low-screen (analog) table
  • High quality (digital) table

        mContext = getApplicationContext();
        IntentFilter ifilter = new IntentFilter(Intent.ACTION_DOCK_EVENT);
        Intent dockStatus = registerReceiver(null, ifilter);

You can extract the current docking status from EXTRA_DOCK_STATE additionally:

        int dockState = (dockStatus == null ?
            Intent.EXTRA_DOCK_STATE_UNDOCKED :
            dockStatus.getIntExtra(Intent.EXTRA_DOCK_STATE, -1));
        boolean isDocked = dockState != Intent.EXTRA_DOCK_STATE_UNDOCKED;
        boolean isCar = dockState == Intent.EXTRA_DOCK_STATE_CAR;

Whenever a device is docked or undocked, the ACTION_DOCK_EVENT action is broadcast. To track changes in the device dock state, simply register the broadcast receiver in the application manifest, as shown in the following snippet below: action android: name = "android.intent.action.ACTION_DOCK_EVENT"

Hope this helps.
