Andorid和IOS如何检测麦克风是否被占用

[jzp12]

for android :

public static boolean checkIfMicrophoneIsBusy(Context ctx){
        AudioRecord audio = null;
        boolean ready = true;
        try{
            int baseSampleRate = 44100;
            int channel = AudioFormat.CHANNEL_IN_MONO;
            int format = AudioFormat.ENCODING_PCM_16BIT;
            int buffSize = AudioRecord.getMinBufferSize(baseSampleRate, channel, format );
            audio = new AudioRecord(MediaRecorder.AudioSource.MIC, baseSampleRate, channel, format, buffSize );
            audio.startRecording();
            short buffer[] = new short[buffSize];
            int audioStatus = audio.read(buffer, 0, buffSize);

            if(audioStatus == AudioRecord.ERROR_INVALID_OPERATION || audioStatus == AudioRecord.STATE_UNINITIALIZED /* For Android 6.0 */)
                ready = false;
        }
        catch(Exception e){
            ready = false;
        }
        finally {
            try{
                audio.release();
            }
            catch(Exception e){}
        }

        return ready;
    }

这个方法对部分机型无效，比如小米。。
