接收电话时，手电筒应用程序并不总是停止

Question

每当收到来电或短信时，我都会尝试关闭手电筒。 它在某些设备（即HUAWEI设备）中运行良好 当我拒绝来电时，我的闪光灯不会熄灭。

 else{
        if(phoneManager.getCallState() == TelephonyManager.CALL_STATE_RINGING){
            if(prefs.getBoolean("call", true)) {
                Log.e("call", "start ->  type:" + prefs.getString("type", ""));
                String tp = prefs.getString("flash_type", "");
                if(!tp.equals(""))
                    flash.startCallFlashLight(getIndex(tp));

                else
                    flash.startCallFlashLight(1);

                lastState = TelephonyManager.CALL_STATE_RINGING;
            }
        }

        else if(lastState == TelephonyManager.CALL_STATE_RINGING &&
                ( phoneManager.getCallState() == TelephonyManager.CALL_STATE_OFFHOOK ||
                        phoneManager.getCallState() == TelephonyManager.CALL_STATE_IDLE)) {
            Log.e("call", "stop");
            flash.stopCallFlashLight();
            lastState = -1;
        }
    }
