Android openPCM16AudioInMemory

[asacque]

I make extensive use of openPCM16AudioInMemory for AdvancedAudioPlayer in my app and everything goes fine.
But this is true only if I set targetSdkVersion 29 (ver.10) in build.gradle.
As soon I set it at 30 (ver.11), or higher, this is what happens:

Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x28 in tid 7620 (AAudio_1), pid 7564 (mant.yyy)
pid: 7564, tid: 7620, name: AAudio_1 >>> com.xxx.yyy <<<
../lib/arm64/libSPAudioEngine.so (Superpowered::bufferList::update()+40)
../lib/arm64/libSPAudioEngine.so (Superpowered::memoryPcmProvider::hasResponse()+92)
../lib/arm64/libSPAudioEngine.so (Superpowered::playerProcess::processAUTHREAD(float**, bool, unsigned int, float*, ...)+1704)
../lib/arm64/libSPAudioEngine.so (Superpowered::AdvancedAudioPlayer::processStereo(float*, bool, unsigned int, float)+72)
../lib/arm64/libSPAudioEngine.so (SampleTrack::process(float*, float, unsigned int)+124)
../lib/arm64/libSPAudioEngine.so (SPAudioEngine::process(short*, unsigned int)+300)

all this with SDK 2.5.0, but tried with 2.6.0 it's the same.
Moreover, I use #define USE_AAUDIO 1 in SuperpoweredAndroidAudioIO.cpp, to get the least latency, but also because if I set it to 0 it gives:

Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x2f7365722f6b70 in tid 8904 (AudioTrack), pid 8867 (mant.yyy)
pid: 8867, tid: 8904, name: AudioTrack >>> com.xxx.yyy<<<

at the launch, and the app doesn't even get started.

Any clue?
Thanx in advance

Thank you for reaching out!

We were able to reproduce the issue. The SuperpoweredPlayer sample app indeed crashes when using openPCM16AudioInMemory. While the issue gets resolved, as a workaround we recommend using the other open methods of the AdvancedAudioPlayer using the file path:

void open(const char *path, Superpowered::httpRequest *customHTTPRequest = 0, bool skipSilenceAtBeginning = false, bool measureSilenceAtEnd = false);

or

void open(const char *path, int offset, int length, Superpowered::httpRequest *customHTTPRequest = 0, bool skipSilenceAtBeginning = false, bool measureSilenceAtEnd = false);

Closing issue, will fix in future version.

Thank you so much for the rapid answer! Although the workaround could not fit my specific use case (I'm implementing a looper, and saving the real time audio input in a file to be opened, in real time, through the path could be not suitable) I'm happy to know that the issue will be fixed in a future release! Thanx again!

I'm also running into this issue when using audioPlayer.openPCM16AudioInMemory. As a workaround I could set android:allowNativeHeapPointerTagging to false. I prefer not to though.

Any idea when this will be fixed?

Yes, setting android:allowNativeHeapPointerTagging to false is a workaround. We are planning to release a fix soon.
