Introduction

I exclusively use Google Voice for texting but find the features of other sms apps to be much better than the Google Voice apps. It seems other do as well since it is built into Cyanogenmod now. I decided to go back to stock and missed the option of using other sms apps with Google Voice. This is based largely off the Voice+ module from Cyanogenmod, but implements its own hooks to know when an sms message is being sent, or Google Voice message is being received.

Installation

  1. Install Google Voice from the play store if you don't have it already
  2. Install the XVoice+ apk from the downloads section at the end of this post
  3. Enable XVoice+ in Xposed
  4. Run the XVoice+ app and select your Google Voice account
  5. Disable "Text Notifications" in the Google Voice app settings to avoid double notifications
  6. Reboot your phone to enable the Xposed module

Note: It my take a few minutes after rebooting before your messages start showing in your sms app of choice. A toast will show when the service is up and running.

On a tablet

I don't have a modern tablet but Link_of_Hyrule put together a small guide about how he got it working.

How it works

Sending

The VoicePlusService runs on startup and listens for a NEW_OUTGOING_SMS so that it knows when a message is being sent. Cyanogenmod made this a system-wide intent, but it is not available on all other roms. Instead, I made my own intent. I hook all outgoing sms messages through the SmsManager and stops them from being sent. Instead I send my custom NEW_OUTGING_SMS intent that is picked up by the OutgoingSmsReceiver which then starts the VoicePlusService. The handling of sending the message via Google Voice is the same logic used in the Cyanogenmod app.

Receiving

Receiving message is done by hooking into the Google Voice app's PushNotificationReceiver. This means that we know of the message as soon as the Google Voice app does. Conveniently, this notification happens even when notifications in Google Voice are turned off, so you don't need to briefly see the Google Voice notification, have it disappear, and then see the sms notification. Once we see we have an incoming Google Voice message, we broadcast another custom intent that is picked up by a IncomingVoiceReceiver which starts the VoicePlusService.The service then handles the message and broadcasts a system wide RECEIVED_SMS intent that is used by all sms applications.

My Testing

I only have a Verizon Galaxy Nexus to test this on. Luckily this can run 4.0.4 through 4.4.x. I'll update this as I get a chance to try new aosp versions.

Side Effects

Because of the way some system apps are being overwrote, I expect that some things will break.

  • All outoging SMS messages from apps that use the SmsManager will be intercepted and sent via Google Voice. To send via your carrier, select "Disable" within XVoice+
  • The app grants itself permission for BROADCAST_SMS which does not appear in the list of permission since it is a system level permission.
  • The app grants itself WRITE_SMS permisson on 4.4+ so that it can save messages in the sms history

Known Issues

  • Receiving emoji causes apps to crash
  • Receiving long messages causes apps to crash
