问题：安卓手机插入OTG摄像头时，如何禁用摄像头自带的MIC？

AudioManager am = (AudioManager)getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
am.setParameters("MIC_CHOOSE=1");
//am.setParameters("MIC_CHOOSE=primary_mic");
/*
am.setParameters("input_source=4;routing=-2147483584;format=1");
*/
try {
    Class audioSystemClass = Class.forName("android.media.AudioSystem");
    Method setForceUse = audioSystemClass.getMethod("setForceUse", int.class, int.class);
    setForceUse.invoke(null, 0, 0);      // setForceUse(FOR_RECORD, FORCE_NONE)
    } catch (Exception e) {
        e.printStackTrace();
    }
}
