android calling crash

[wangdu89]

Using a HUAWEI mate9 cell phone, a few minutes after a phone call, the program is crash.
1: compiled without webrtc, the phone will not be crash, but the echo is very large
2: compilation uses webrtc, not speexdsp, nor crash, but webrtc noise initialization fails
In audio session, I found this error: "WebRtcNs_Init failed with error code =
-1"

Please provide any additional information below.

Is there any progress?
