with version 0.5 this app become one of the top 10 to have ;)

great job

Andorko, what kernel changes needs to be done to get RDS working? Does this change require a RDS capable app or will or work "just like before" with non-RDS apps?

Also I've found a way to change the kernel so that the original Radio app works so that whatever workaround you used to not being turned off after 3 seconds are no longer needed.

It seems that on the 2.2 ROM the radio triggers the use of a different device ID for headset which likely some firmware on our phones cannot handle. So what I did was that I catched and changed the radio headset id and changed in to the normal headset id.

In arch/arm/mach-msm/qdsp5/snd.c:

Change:

		mutex_lock(&snd->lock);

		switch (cmd) {

		case SND_SET_DEVICE:

				if (copy_from_user(&dev, (void __user *) arg, sizeof(dev))) {

						MM_ERR("set device: invalid pointer\n");

						rc = -EFAULT;

						break;

				}


				dmsg.args.device = cpu_to_be32(dev.device);

				dmsg.args.ear_mute = cpu_to_be32(dev.ear_mute);[/code]


To:[code]		mutex_lock(&snd->lock);

		switch (cmd) {

		case SND_SET_DEVICE:

				if (copy_from_user(&dev, (void __user *) arg, sizeof(dev))) {

						MM_ERR("set device: invalid pointer\n");

						rc = -EFAULT;

						break;

				}


				// FM_STEREO_HEADSET -> HEADSET

				if(SND_DEVICE_FM_STEREO_HEADSET_ZTE == dev.device)

						dev.device = 3;


				dmsg.args.device = cpu_to_be32(dev.device);

				dmsg.args.ear_mute = cpu_to_be32(dev.ear_mute);

After this the stock Japanese unmodifed radio app works again. (I was actually looking for some way to boost the volume in the kernel when I stumbled upon this)

Is it therefore possible to direct the FM radio output to a more general audio output ? --- thereby opening up the possibilities of internal speaker or Bluetooth --- though obviously, you'd need the headset connected to have an antenna ...

I really don't know if this opens any new doors but I believe this is the device ID the radio identifies itself with in 2.1 but someone would need to do "cat /proc/kmsg|grep snd_set_device" to be sure and I am bit sick and tired of reflashing at moment. The first number is the device and without headset inserted it reports 6 and with it inserted it reports 3 but once you start the unmodified radio app it reports 32 and there is a check for that in the code that isn't present in the 2.1 kernel. (just removing the check results in a total reboot if you start the radio app, but changing the device id to 3 (headset) works like a charm.

I have made a second RDS test version:

-The tuning and and seeking is faster

-More stable RDS StationText, it handles dynamic StationText too.

You can download it from my download page (it is on the bottom of the page)

Excellent news -- I'll give it a try today!

Thanks for your efforts!

Please could you offer your RDS kernel patches to the ROM devs?

Or post them here so that we can point Paul, KK and the rest to them?

My donate threshold is when I have RDS radio on Pauls MCR 2.2 but using a Paul-provided kernel on one of his kitchen roms

Thanks

January 24, 2011

HUMPH.

This may just be me because I have NOT plugged headphones in [looking for mine!]

But nothing happens when I use the "circle" at the top or the "wheel" at the bottom - the frquency does not change.

What is the problem please?

If you don't put the headphones in, then all the controls are disabled.

Just to let everyone know, kaltkaffe has fixed the problem with the original FM Radio app in Japanese Jellyfish R9.

Of course I will share my kernel modifications with the ROM devs, but, because it is a kernel modification it should be bug-free before it is put into the newest ROMs.

January 24, 2011

My modifications are more than just listening to radio on 2.2. There is RDS in the fm chip, and i hope there is TMC too. But to use this features , fm driver in the kernel have to be modified.

January 24, 2011

You did great job!!! Works great! no issue until now.

If you accept feature requests, i will love to be able to assign names on the 'stored' stations, and also to be able to store more than 5 stations.

Also, can i install this app along with the stock fm app?

Thanks!

The not working loudspeaker was really bugging me, so I installed the Android SDK and started playing with a simple app.

My goal was to play a mp3 file through the loudspeaker, while the headphones are connected.

What this app does:

Plays a predefined (marchin.mp3, not attached, use your own) from sdcard. Shows a very simple app with a toggle button. Upon toggle app switches playback between wired headset and loudspeaker.

I'm actually not sure, if andorko can adapt this, but I hope so. I'm attaching all related code in codetags in this post.

@andorko and other devs

feel free to use (a credit if this works would be nice though :lol: )

If you for some reason don't want to read through all the code, I added the most relevant bits at the end of this post.

@all

If anyone wants to try this in android sdk, fell free. But be aware that I'm not attaching the mp3 I used.

You need to place a "marchin.mp3" on your root sdcard directory or adapt the code.

		}


		// Get the button from the view

		playerButton = (Button) this.findViewById(R.id.play);

		playerButton.setText(R.string.on_label);

		playerButton.setOnClickListener(this);


		// Begin playing selected media

		player.start();

	}



	private void speaker_On() {

		/* Without setting MODE_IN_CALL setSpeakerphoneOn does have NO EFFECT!!

		 * Dirty workaround.

		 */

		mAudioManager.setMode(AudioManager.MODE_IN_CALL);

        mAudioManager.setSpeakerphoneOn(true); 


        playerButton.setText(R.string.on_label);

        Toast.makeText(this, isOn, Toast.LENGTH_LONG).show();

        Log.d(TAG, isOn);

	}


	private void speaker_Off(){

		/* Set Mode back to normal

		 * 

		 */

	    mAudioManager.setMode(AudioManager.MODE_NORMAL);

        mAudioManager.setSpeakerphoneOn(false); 


        playerButton.setText(R.string.off_label);

        Toast.makeText(this, isOff, Toast.LENGTH_LONG).show();

        Log.d(TAG, isOff);

	}


	// Toggle between the play and pause

	private void toggle() {

		if(mAudioManager.isSpeakerphoneOn()) {

		  speaker_Off();

		} else {

		  speaker_On();

		}	

	}


  @Override

  protected void onDestroy() {

      super.onDestroy();

      // TODO Auto-generated method stub

      if (player != null) {

          player.release();

          player = null;

      }

I'm on MCR 2.2 R7. I don't know if this works on 2.1.

If you're too lazy to read all this code. Relevant stuff:

Set "android.permission.MODIFY_AUDIO_SETTINGS" in Manifest.

Set "mAudioManager.setMode(AudioManager.MODE_IN_CALL);" before setting "mAudioManager.setSpeakerphoneOn(true);"

Without MODE_IN_CALL setting Speakerphone doesn't work. This is a dirty workaround. I don't know how the phone will behave, when playing mp3/radio(if andorko can adapt this) through Speakerphone and getting a call in. Didn't test this.

But maybe this leads some dev onto the right path. (Or it actually works flawlessly this way).

The not working loudspeaker was really bugging me, so I installed the Android SDK and started playing with a simple app.

This trick doesn't work with the fm radio. If i play radio and an mp3 simultaneusly on the headphones and then execute the :

mAudioManager.setMode(AudioManager.MODE_IN_CALL);

mAudioManager.setSpeakerphoneOn(true);

then the mp3 plays through the speakerphone but the radio disappears.

January 24, 2011

Bummer :lol:

Sounds like the mp3 sound is re-routed correctly and the fm sound is not.

Why are you playing an mp3 file anyway? I only used this method cause I wanted to try the toggling and i didn't have the radio source code to try directly.

anyway, thanks for trying andorko

I'm off to bed now, getting late here. gn8

I was playing an mp3 with the "Music" player just for testing that i didn't make a mistake in the code.

You are great!! it work very well now. Only 1 (really little) thing i see if i start with rds disabled the app tells me "RDS: loading..." there should be "RDS: disable".

Do you plan more with the rds-feature? as i said it seems to be very stable yet. i dont know if anyone else found a bug, but i think you could remove the testversion line, center the rds line and resize ist a little bit bigger.

I hope you solve the loudspeaker problem. ;-)

Thank you very much for your time and the great app!

EDIT: I found a Bug: i click on the arrow of the volumne-circle (highest volumne). then i click on the "turn on/off button" and turn again on with klicking on "turn on/off" butten volumne seems to be 0. if i klick on the volumecircle i volumne is again normal. i think the volumne should be evertime the state in the circle.

I believe this is the device ID the radio identifies itself with in 2.1 but someone would need to do "cat /proc/kmsg|grep snd_set_device" to be sure

Confirmation for you:
