Android Question Access AudioRecord Methods

[Nataly]

Hello, I'm trying to access the getBufferSizeInFrames using java object. Here 's the code:

Dim joAudioRecord As JavaObject
joAudioRecord = joAudioRecord.InitializeStatic("android.media.AudioRecord")
Dim frames As Int = joAudioRecord.RunMethodJO("getBufferSizeInFrames", Null)
Log(frames)

But I got the following error:
java.lang.IllegalArgumentException: Expected receiver of type android.media.AudioRecord, but got java.lang.Class<android.media.AudioRecord>

Although I tried to get the getMinBufferSize method same way and It worked. Here's the code:

Dim joAudioFormat As JavaObject
joAudioFormat = joAudioFormat.InitializeStatic("android.media.AudioFormat")
Dim joAudioRecord As JavaObject
joAudioRecord = joAudioRecord.InitializeStatic("android.media.AudioRecord")
    
Dim SampleRate As Int = 8000
Dim channelConfig As Int = joAudioFormat.GetField("CHANNEL_IN_MONO")
'Dim channelConfig as Int = joAudioFormat.GetField("CHANNEL_IN_STEREO")
Dim audioFormat As Int = joAudioFormat.GetField("ENCODING_PCM_16BIT")
'Dim audioFormat as Int = joAudioFormat.GetField("ENCODING_PCM_8BIT")

Dim buffSize As Int = joAudioRecord.RunMethod("getMinBufferSize", Array As Object (SampleRate, channelConfig, audioFormat))
Log(buffSize)

Why am I getting such error and how can I avoid it?
Thank you,
Nataly

Why am I getting such error

Because it is not a static method.

and how can I avoid it?

You need to get a reference to the action AudioRecord object. This is all that I can say based on the information you posted.

Why aren't you using AudioStreamer?

How can I do that?

Because I want to access methods such as getBufferSizeInFrames, to help me in configuring opus codec.
