Two days ago my Galaxy Note 3 updated to the OS KitKat 4.42. Ever since that update the app freezes after playing a few songs. It also freezes if you close the app and let the music keep playing. Usually when you open the app back up the app will freeze. The only way to fix it is to restart the phone. I do know that one of the new features of 4.42 is music lockscreen features. Don't know if that info helps.

Let me clarify the issue:
1. Once playback is started changing tracks at some point freezing HomeDJ Player;
2. After freezing message box appeared, and screen turned off, screen never comes back;
3. Phone reboots on itself.

Is this kind of symptoms you are experiencing? I was able to reproduce it. Found faulty code and will post a fix after testing for at least a day.

This behavior only appears on KitKat and only on Samsung Note 3 At&T KitKat version.

Solution to avoid freezes is to disable FadeIn and FadeOut for Play/Pause/NextSong in HomeDJ Settings:

Settings->Advanced->Uncheck both checkboxes at the bottom of Advanced section:
Play FadeIn - CHECK OFF
Pause FadeOut - CHECK OFF.

These both options will be removed in the next release.

Thank you.

Done as much clean up as possible. Ran through memory leak check and everything looks ok. Running tests. Even without HomeDJ my Note 3 on KitKat sometimes just restarts. Something went wrong with Samsung KitKat modifications. Other devices on KitKat I have do not have this kind of issues.

Here is an example where people reporting Note 3 sudden restarts and freezes on KitKat:

For those who is experiencing freezing under KitKat Galaxy Note 3 (probably only AT&T variant) problem was detected. The issue is that equalizers used by Android (MusicFX) codecs are not supporting multiple instances of Codec allocated at the same time and not releasing resources, leading to System memory leaks and phone complete freeze. HomeDJ is using multiple instances (max 2) to support gapless playback and cross-fading.

To temporary solve this issue while I am still working on a fix, is to disable control of MusicFX by going into HomeDJ Player settings:
Settings->Advanced->Disable SoundFX - CHECKED.

I am still working on a fix trying to serialize access to coded as well as going to develop HomeDJ own Equalizer application, which will try to support multiple instances of AudioEffect allocated.

Instead of Android build-in MusicFX equalizer, I would recommend to use Equalizer, which can equalize sound even with disabled option to control MusicFX equalizer in HomeDJ Settings->Advanced.

For those who is rooted Viper4Android or DSPManager are the best equalizers out there. They support multiple codecs instances and provide best quality of equalization without loss of volume. Unfortunately for AT&T users it is no longer possible to use these best equalizers, because AT&T locked bootloader and it is not possible to flash any mods or any new ROM or even downgrade from KitKat back to Android 4.3.

Recommended HomeDJ settings while using Equalizer:

Settings->Advanced->Disabled SoundFX (CHECKED)

Settings for Equalizer is to Enable notification. This is to access equalizer from Notification bar, because when HomeDJ SoundFX control is disabled, Equalizer button in the player will not open equalizer.

I will enable this button regardless settings for SoundFX control checked o unchecked in the next release of HomeDJ Streamer.


Thank you.
