Pass your slides on Google Drive using your phone or watch

WatchPresenter is an application that let's you control Google Slides from either your SmartWatch or your SmartPhone.

Note: This is not an official Google product and is not supported by Google in any way.

How it works

The application uses two components to perform its task:

• A Chrome extension
• A mobile app

Users can signal a slide change by several means:

• Tapping on the phone screen
• Clicking on the phone's volume buttons
• Tapping on their Android Wear SmartWatch

The latter two methods do not require the phone screen to be on, hence saving battery and preventing unintentional slide changes.

Whenever the user signals a slide change, the mobile app sends a message to the Chrome extension by using Google Cloud Messaging system. An identifier is used, so that messages from the app are sent to the appropriate destination (the Chrome browser of the user). The identifier is based on the Google Account name, so the user must use the same Google Account on both the browser and the phone.

Modules and file structure

On the project root you will find the following folders:

• 'android': Contains the android App source code. It is an Android Studio project (Gradle build).
• 'chrome': Contains the source code for the Chrome extension. See README file in that folder for more info.
• 'resources': Contains other resources such as icons, etc. Both in source and binary forms.

watchpresenter's Issues

Background audio keeps on playing after notification dismissed

Unable to detect Chrome Extension

Hi all,

I've installed Watchpresenter 2.0.5 onto my Galaxy S6 running Android 5.1.1 and the Chrome extension version 3.3 onto my laptop version of Chrome. When I open the Google slides deck I see the Watchpresenter icon come up at the far right of my address bar, but my phone does not detect the Chrome extension. Both my laptop and phone are on wifi and able to access other internet services normally.

Any ideas?

Edit: I am signed into my Galaxy S6 and Chrome browser under the same Google account

KeyPress service stays up if button pressed immediately after notification dismissed

Moto 360 moving to next slide on random gestures

When moving your arm from being down to up (as if to read the time) it will move to the next slide. Seems over sensitive with the movement and will move on from only a little movement.

Potential issue for integer overflow

Hi

I've found a following suspicious code in android/WatchPresenter/backend/src/main/java/com/zuluindia/watchpresenter/backend/Cleanup.java

In Line 60:
private static final long EXPIRY_MILLISECONDS=63 * 24 * 3600* 1000;

Could this be as follow to avoid integer overflow?:
private static final long EXPIRY_MILLISECONDS=63 * 24 * 3600* 1000L;

This might be a trivial thing but I wanted to report just in case.

Thanks!

Messages not arriving to Chrome on certain WiFi configurations

When using Chrome on some WiFi networks, even though there is Internet connection, the GCM messages are not arriving to Chrome. A pattern of when this is happening could not be found yet

Support for playing videos directly from the app

This goes way beyond just passing slides, but it would be nice to be able to play videos embedded in the presentation

FR: Prevent button presses from switching slides when in call

FR: Avoid app volume change

Some ideas...

@OverRide public boolean onKeyDown(int keyCode, KeyEvent event){ if (keyCode == KeyEvent.KEYCODE_VOLUME_UP){ Toast.makeText(this, "Volume Up", Toast.LENGTH_LONG).show(); return true; } if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN){ Toast.makeText(this, "Volume Down", Toast.LENGTH_LONG).show(); return true; } return super.onKeyDown(keyCode, event); }

FR: Stop passing slides when call is active

In the event of a call, the user is probably not presenting anymore. However, volume key presses are detected if the application is active. This might lead to unwanted slide pass.

Only advances once with volume buttons

It was working fine until recently. Now the volume buttons will only advance once, then no response.

The next slide button in the alert works still.

Throw in Finally

Any exceptions thrown from the try or catch segments are eliminated when an exception is thrown in the finally block
