In this section, we'll cover the functions shown in the screenshots.
Our SDK provides many more functions that let you configure your
meeting. Refer to our [SDK
reference](https://marketplacefront.zoom.us/sdk/meeting/android/us/zoom/sdk/package-summary.html) for more information.

## Lock the meeting

To block new participants joining your meeting at any time,
pass a boolean value to
`inMeetingService.lockMeeting()` like this:

```java
// Lock the meeting
inMeetingService.lockMeeting(true);

// Unlock the meeting
inMeetingService.lockMeeting(false);
```

Note: You need to instantiate an `inMeetingService` object before
calling this function.

## Lock sharing

If you would like to forbid your participant to share contents, or not
allow them to share anything, firstly, you need to get an
`inMeetingShareController` instance from your `inMeetingService` object.

```java
InMeetingShareController inMeetingShareInstance = inMeetingServiceObject.getInMeetingShareController();
```

Then, simply call `lockShare` function and pass a boolean value
(True/False) to lock participants' ability to share contents.

```java
// Lock share
inMeetingShareInstance.lockShare(true);
// Unlock share
inMeetingShareObject.lockShare(false);
```

## Mute upon entry

If you would like to mute every participant when he/she enters the
meeting room, similar to `lockShare`, firstly you need to get an
`inMeetingAudioController` instance from `inMeetingService` object:

```java
inMeetingAudioController inMeetingAudioInstance = inMeetingServiceObject.getInMeetingAudioController();
```

Then, simply call `setMuteOnEntry` function and pass a boolean value to mute or unmute participants upon entry.

```java
// mute participants upon entry
inMeetingAudioInstance.setMuteOnEntry(true);
// unmute participants upon entry
inMeetingAudioInstance.setMuteOnEntry(false);
```

## Play the enter or exit chime

When a participant enters or exits the meeting room, a chime sound plays. To disable the chime, pass a
boolean value to enable or disable the chime sound.

```java
// enable chime
inMeetingService.setPlayChimeOnOff(true);
// disable chime
inMeetingService.setPlayChimeOnOff(false);
```
