[App] BTmono - v1.2 - ICS Fixes - Yum

bedoig · Feb 11, 2011

My first Android application! BTmono

Description:

Simple app to stream audio to your bluetooth mono headset.

Released as donationware, so if you like it show your appreciation

Requires Android 2.2 or higher. Tested on stock HTC Evo 4G ROM (2.2) and CM7 RC1.

Notes:
- Make sure your headset is connected BEFORE clicking 'On'
- To use with Skype you must enable BTmono AFTER starting a Skype call.
- To reduce static, set the 'Media Volume' slider to max and reduce the 'Bluetooth In-Call Volume' via your phone/headset.
- This version contains a workaround for a bug in Android 2.2 which causes a system crash under certain circumstances. If you are on 2.2, do NOT disable Bluetooth while the stream is running or your phone WILL reboot (sorry - tell your phone manufacturer to move to 2.2.1+). The bug has been fixed as of Android 2.2.1.

Features:
- Widget!!
- Automatically enable Bluetooth on app launch (user can still choose not to allow this). Make sure your headset is actually CONNECTED before hitting 'On.'
- In-app 'Media Volume' control. Adjust the 'Bluetooth In-Call Volume' using the physical buttons on your phone or headset.
- Ongoing Status Bar notification while the program is running.
- Skype support (if enabled after call is started)

To-do:
- Possible - map headset button to 'next track'
- Other features?

Changelog:

v1.2
- fix crash on ICS
- fix status bar icons on Android 3.0+
- utilize new bluetooth "in-communication" mode for Android 3.0+. *Should* integrate better with VOIP apps, etc.
- automatically detect if user is on Gingerbread or greater - no need to select the Android 2.2.1+ setting in preferences. If you are on 2.2.1 you still need to select this for a cleaner shutdown when you press Off. There was no API level change between 2.2 and 2.2.1 so I can't (easily) do it for you automatically.

v1.1.1
- choose Android's color

v1.1
- Auto reconnect after phone call

v1.0
- Widget!
- Rewrite to eliminate disconnects (hopefully)
- Option for better shutdown on 2.2.1+

v0.3.1
- user prefs - Auto-On

v0.3
- small UI change - Android says hi

v0.2
- added in-app 'Media Volume' control
- added bluetooth check on startup
- added ongoing activity notification

v0.1 - initial release

Sweet. How does music sound when going through this? Also, are you saying there is no way to alter the media vlume when this is running?

Description:

Requires Android 2.2 or higher. Tested on stock HTC Evo 4G ROM (2.2) and CM7 nightlies.

Notes:
- Turn on bluetooth and set media volume to desired level before running the app (will do this automatically in future releases if there is demand for it).
- This version contains a workaround for a bug in Android 2.2 which causes a system crash under certain circumstances. The bug has been fixed as of Android 2.2.1, so future releases will include an Android version check and alternate (better) shutdown method for 2.2.1+.

To-do:
- Check if Bluetooth is enabled at app launch (and enable it if it's not).
- Widget. Thanks pure_energy1 @ XDA for reminding me.
- possible (if requested) - disable bluetooth when you turn off streaming.
- possible (if requested) - set media volume to predefined level before enabling bluetooth stream.
- Version check and different shutdown for 2.2.1+
- Other features?

I've been looking for something like this, thank you!

Sound quality blows, but that's just the way it is. It's mainly just for people who have an old mono headset laying around and want to listen to podcasts, etc.

Unfortunately, there is no way to change 'Media' volume while it's running. You can adjust 'Bluetooth In-Call' volume, but if your media volume is muted you won't hear anything.

please don't

Turn on bluetooth and set media volume to desired level before running the app (will do this automatically in future releases if there is demand for it).

please dont do this! applications that alter volumes are really bad. user does not know about it , and then in a quiet room later you will suddenly be balsted with some sounds, when u turn off BT.
also another app could be running at the same time, and you have no way of knowing what the user wants.

karl999999 · Feb 11, 2011

skype

As for the microphone, I hadn't really considered that. I was thinking of this as purely a means of getting audio from the phone to the BT headset. Does Skype not work with a BT headset using the standard headset profile?

i hope u can also do mic.
no skype unfortunately (on my galaxy s) does always use the phones speaker and cant use the headset :-(
so i was waiting for an app like that for a long time.

karl999999 · Feb 11, 2011

another question:
why must the sound quality be bad?

just because its mono? or because of BT? i dont understand

Point taken. I could save the unadjusted level and restore it to that when disabling though.

I'll look into the mic. I figured Skype would work with a headset by default.

The telephony/headset profile uses low quality audio. OK for calls, sucks for music. If you need high quality audio you'll need to get an A2DP headset.

karl999999 · Feb 11, 2011

i hope this will be a configurable option [yes/no]
because if another program is running also (mutlitasking) then setting the level back to what it was before , may also be wrong and confuse the user.
if the user has meanwhile changed the volume in another program.

Well, the easiest thing would be to just leave it how it is

So unless other people want the option to set media volume, I'll just leave it alone.

I'd at least love the auto turn bluetooth on(if off), and then auto turn off(or leave on if it was on originally).

nice one : )

I found 2 apps like this for 5$, but it doesn't worth it because the sound quality
But now I will test it for a few days, and if I can use it with my white eares, I'll send you some money

Or you can just add an advertisement line to the bottom : ) And if you promote it enough, than you can get some money for your work - just think about the Angry birds, they have a lot of income from ads

My BT works with music without an app...

Maybe not all BT have a media profile?

Now what would be really cool and worth while, is an app that I can choose exactly what audio goes through the BT. Just for example have my navigation directions through the BT but music through the audio port.

Sent from my PC36100 using XDA App

Great app! Why does it require froyo though?

Isn't it supported in eclair?

beepsilver · Feb 12, 2011

I'm an unrooted Evo user with stock 2.2 ROM. I installed the program and tried it with a non-A2DP Plantronics bluetooth. I ran into problems when I received a phone call while listening to streaming music--the phone call came through, and the music went silent in the bluetooth, but the music switched back to the phone and continued to play. When the phone call was complete, the music did not resume in the bluetooth. I had to manually go back and turn off/on the BTMono app to resume.

A more significant problem is when I physically turn off the bluetooth while BTMono is streaming music for me, the phone autorestarts....it apparently did not like that action. I do not know if physically turning off the bluetooth headset while BTMono is turned on, but not streaming music would result in an autorestart.

Thanks, and please let me know if I can make adjustments on my phone or if this is an app issue that can be worked out.

Agreed, I would be interested to have a choice of "what" is sent to BT. Navigation to BT is a big boon to me a well - this is a good start!

Suggestion, some way to tell when BTmono is "on" would be great, .e.g. tray indicator or app icon changes color.

Cheers

Good ideas everyone! Keep them coming.

I'll address everyone's specific questions/comments late on Sunday or Monday. Got a busy weekend

sounds good - may have to give this a quick go

alphaeagle777 · Feb 12, 2011

To control the media volume you could use audio manager, I tried and it work
