Music cannot be played after compilation on android.

[ТН Н]

I'm using SoundLoader. Everything works on windows and linux. After compilation on android - silence

[planckp...@gmail.com]

1) Always search for a solution before you post.

2) Working on Windows/Linux is often necessary but not sufficient for working on Android. The assumption in the post is flawed.

3) If you post, post a small runnable example. "It doesn't work" is not actionable by anybody else.

OK so you'll do it right next time.

Search in the box above for         soundloader test case

The first thread is from a week ago it discusses this issue, about half way though is a working test case. Start from that.

Kivy doesn’t play MP4 audio on Android. Try OGG. If that doesn’t work, try WAV (not recommended ‘cause it makes the largest files).

I looked everywhere. I asked questions on two forums, they did not answer. There is nothing specific in my code.

Builder.load_string('''

            pos_hint:{'center_x': .5, 'y': .8}
            on_release: root.enable()

class Start(Screen):
    def enable(self):
        sound = SoundLoader.load('Music/music.mp3')
        sound.play()
sm = ScreenManager(transition = NoTransition())
sm.add_widget(Start(name = 'one'))

class MyApp(App):  
    def build(self):
        return sm

MyApp().run()

Is this what happened?

- MP3 = Silence

- WAV = Sound, but not the file you loaded

If so, try converting your audio to an Ogg Vorbis file and compressing it.

Read the comments in that post so that buildozer.spec is correctly edited.

mp3 is not available via Soundloader on Android, use ogg or wav

No, wav is also silence. Did as you said, the result is the same :-(

Maybe when compiling, you need to add a request for permission to play audio or something similar?

I found that topic. The test case didn't work. After the change .spec (instead of kivy, I wrote kivy == 2.0.0), the application generally began to crash at startup.

All you have to do is:

1) install Buildozer  https://buildozer.readthedocs.io/en/latest/installation.html

2) Create a new directory containing the example as main.py , and the .wav

3) Follow the instructions https://buildozer.readthedocs.io/en/latest/quickstart.html

4) after 'buildozer init' make the two changes to buildozer.spec, and only those changes.

Check the buildozer log for fatal errors, it is very verbose but fatal errors are usually clear, warnings can usually be ignored.

To be actionable we need an error message that says why it is failing.

Without that I cannot suggest anything.

[ТН Н]

In the test example, where there is nothing but a button that turns on the music, it worked. Do you think the problem is in the main program or the buildozer.spec file?

[planckp...@gmail.com]

That is great, I did not know till now that the test worked for you. We can move forward.

The conclusion you make is reasonable.

I expect it is not the .spec , and you can test this by using the .spec from the test for your app (assuming .wav)

If you do this in your app's directory do a 'buildozer appclean' first.

I don't know the cause of the issue without debugging your app for you, which I don't do for anybody.

I will help you to learn how to do it.

The way to debug an app on android is to look at the logcat output of Buildozer ( see quickstart).

The phone must be connected via USB, with 'Developer mode' and 'USB Debugging' enabled.

Search in the logcat for 'Traceback', following that you will see a Python stack trace, the last line of which is the most important.

It will perhaps say something like file or symbol not found, but of course you need the real message.

It seems to me that there is no, so I tried to use adb logcat, crawled all over the Internet, tried all the ways, but nothing helped with the fact that adb saw the smartphone(ubuntu itself sees).

This should be something like:

List of devices attached
0A051FDD40019P  device

So adb does not see the phone.

The issue is presumably in the phone debug settings since Ubuntu see the phone.

The usual ones I described in my previous post, but some phone models are different (I don't know about this).

No idea, all I can suggest is reboot both the computer and the phone. But you probably tried that.

FYI I will not be available for about a week.

The situation has become even more interesting: I managed to make the device display via adb devices, but buildozer android deploy run logcat still doesn't see it.
