I'm trying to do a simple talk-through using libpd with android studio.

adc~ -> *~ 0.5 -> dac~

However, I do not have an android phone, so I'm using an Android Studio emulator (Nexus 4, api 23).
I can't get any input from my laptop microphone (or from my earphones built-in microphone when I try that).
Is there something I'm missing?
I know when using Record_Audio directly in Android studio, you need to add permission.
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
Is my issue something along these lines?
Or is it a limitation with using emulators?
I've read many questions on forums about it, but not many are recent and there seems to be many conflicting answers also.

All the best

Firstly, my targetsdkversion was API 23. As pointed out:
"Requesting permissions in API 23+ is something that needs to be done in the app itself, not in the pd-for-android library."
So I changed the target sdk version to 22.

Additionally, I had not added permission to my manifest to use the microphone. So adding this line to the Androidmanifest:
<uses-permission android:name="android.permission.RECORD_AUDIO" />

Finally, I forgot to change the number of input channels from 0 when changing the source source from a osc~ to adc~. So my initPD method now looks like:
int sampleRate = AudioParameters.suggestSampleRate();
int inpch = AudioParameters.suggestInputChannels();
PdAudio.initAudio(sampleRate, inpch, 2, 8, true);
