Android Question MediaSessions

[Jmu5667]

Hi All

Does anyone have any sample code, I image it would use JavaObjects, showing how to use the MediaSessions Class. I am specifically referring to http://developer.android.com/refere...(android.media.session.MediaSession.Callback) to receive the media button events.

I would be happy to share my code when I have this solved as i know that others @lemonisdead have had issues with the same.

Regards

John.

I can't seem to find the MediaSessionCompat Class in the latest android-support-v4 jar file. Does anyone have any idea where it may be? The documentation doesn't say.

 

[stevel05]

OK that's because there is a new V4 file in the V7 folder! Now I've found it

Hello
Thanks again for all the work and research you did. Please, don't take it bad it is not a request at all but, on the Nexus 7 and Wiko mentioned above, I don't get any more results (even after having used your latest code). As I wasn't really working on it (but more testing for John), I will wait to see if he has got the same results.

 

[stevel05]

Just tried it again, it's still working here. Did you add the line:

session.RunMethod("setFlags",Array(3))

in service create?

 

[lemonisdead]

Absolutely (I copied/pasted the whole code).

 

[stevel05]

I have android 6 on my Nexus, could be the difference. Let's see if John has any luck.

hi guys, I am out of the office at the moment, I will try it later on tonight or first thin in the moring.

 

[stevel05]

I just tried it on my Sony Experia (Android 5.1.1) it work's intermittently in Debug mode, but seems OK in release mode.

Good Morning all,

I picked up a HTC ONE M7 yesterday, it has Lillipop 5.02 (21) in it. attached is a simple program using steve's sample code. I have MiKey in the headphone socket and the intents are being captured. It appears to work quite well in release mode. Please try it on your devices. There is no entry in the manifest file for the media which is nice.

I had a look at which discuss's the mediaSessionComat class. As steve mentioned there is a JAR for this and it will enabled backward campatability for API < 21 to handle the media button capture. This is the ideal solution. I am not too sure how to work with the additionalJar etc.

Regards

John

Hi John. I have looked at this today, and it is working with compat, but it's very unreliable. I'll have a look tomorrow and see if it can be improved. I think something may be stealing the clicks. Sometimes it records all of them, sometimes one or two and othertimes none.

 

[stevel05]

Can you try this out, I don't think it's my hardware that is causing the issue, but I don't want to be chasing it down if it is.

Morning Steve

I get the following when I compile. Which jar file are you using ?

This is the one that I have and I have it in in 'C:\Users\John Murphy\Documents\B4A\Additional Libraries'

Sorry, yes I forgot to say, it the android-support-v4.jar that will be in the v7 support directory of your SDK.

Hi Steve, my v7 support does not have that file, it's only in the v4 folder

 

[stevel05]

Hi John, It's in the Android support library V23.1.1, you'll need to update it through the SDK manager, It should then be there.

Hi Steve

Thanks for the update. I did find a support-v4-23.1.1-sources.jar (google search) buried in the SDK folders. This is what I get when I compile:

Hi John,

It's not the -sources jar you need. On my system it's in the SDK folder: android-sdk\extras\android\support\v7\appcompat\libs\android-support-v4.jar.

This is the folder that you are referring, are yours the same ?

Regards

John.

 

[stevel05]

Yes looks the same size at least. Did you overwrite the previous one in your additional librariess folder?

 

[stevel05]

Just a thought, do you have an android-support-v4.jar in your core libraries folder?
