Too small buffer size in Android demo

[nshmyrev]

Here you use minimal buffer size, sometimes it can be 80 ms. If recognizer is slow and can't manage in 80 ms samples can get lost and accuracy will degrade.

Its recommended to use bigger buffer, maybe 0.5 seconds to not compromise latency.

Do you mean we need to hardcode it to 0.5 seconds?

[nshmyrev]

It can be max(minBufferSize, 0.5 * sample_rate)

Would you mind creating a PR to fix it?

[nshmyrev]

Sure, I'll submit one a bit later
