trouble in Android Message

要使用NeuroSky的MindWave來抓一些腦波資料，他提供的Android API利用handler回傳message來回傳mindwave所抓到的腦波訊息。

在使用上我需要將EEG訊號儲存在Sqlite中，因為raw data的偵測與傳送速率是512 Hz，且官方所給的範例使用的handler是UI thread handler。自己寫的程式使用此handler來儲存資料會使得UI thread產生ANR的問題。

因此想先將偵測到的message儲存在一個容器內，然後呼叫另一個thread批次的儲存在Sqlite中。

然後慘劇就發生了，不曉得為什麼容器內的message會被當作垃圾回收！

handler程式碼如下：

    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {
            case 0:
                Log.i(TAG, "got Message 0");
                break;
            case TGDevice.MSG_STATE_CHANGE:
                switch (msg.arg1) {
                    case TGDevice.STATE_IDLE:
                        break;
                    case TGDevice.STATE_CONNECTING:
                        SensingActivity.setState("Connecting...");
                        break;
                    case TGDevice.STATE_CONNECTED:
                        SensingActivity.setState("Connected.");
                        SensingActivity.getTGDevice().start();
                        break;
                    case TGDevice.STATE_NOT_FOUND:
                        SensingActivity.setState("Can't find");
                        break;
                    case TGDevice.STATE_NOT_PAIRED:
                        SensingActivity.setState("not paired");
                        break;
                    case TGDevice.STATE_DISCONNECTED:
                        SensingActivity.setState("Disconnected mang");
                }
                break;
            case TGDevice.MSG_POOR_SIGNAL:
                //signal = msg.arg1;
                SensingActivity.setState("Poor Signal: " + String.valueOf(msg.arg1));
                break;
            case TGDevice.MSG_RAW_DATA:
                //msgBuffer.add(msg);
                msgBuffer[index] = msg;
                Log.e(TAG, "In: msg.what = " + msgBuffer[index].what + ", msg.when = " + msgBuffer[index].getWhen() + ", number = " + index);
                index++;
                break;
            case TGDevice.MSG_HEART_RATE:
                break;
            case TGDevice.MSG_ATTENTION:
                //msgBuffer.add(msg);
                //msgBuffer[index++] = msg;
                msgBuffer[index] = msg;
                Log.e(TAG, "In: msg.what = " + msgBuffer[index].what + ", msg.when = " + msgBuffer[index].getWhen() + ", number = " + index);
                index++;
                SensingActivity.setAtt(String.valueOf(msg.arg1));
                SensingActivity.setp1(msg.arg1);
            case TGDevice.MSG_MEDITATION:
                //msgBuffer.add(msg);
               // msgBuffer[index++] = msg;
                msgBuffer[index] = msg;
                Log.e(TAG, "In: msg.what = " + msgBuffer[index].what + ", msg.when = " + msgBuffer[index].getWhen() + ", number = " + index);
                index++;
                SensingActivity.setMed(String.valueOf(msg.arg1));
                SensingActivity.setp2(msg.arg1);
                break;
            case TGDevice.MSG_BLINK:
                msgBuffer[index] = msg;
                Log.e(TAG, "In: msg.what = " + msgBuffer[index].what + ", msg.when = " + msgBuffer[index].getWhen() + ", number = " + index);
                index++;
                break;
            case TGDevice.MSG_RAW_COUNT:
                //tv.append("Raw Count: " + msg.arg1 + "\n");
                break;
            case TGDevice.MSG_LOW_BATTERY:
                //Toast.makeText(getApplicationContext(), "Low battery!", Toast.LENGTH_SHORT).show();
                break;
            case TGDevice.MSG_RAW_MULTI:
                //TGRawMulti rawM = (TGRawMulti)msg.obj;
                //tv.append("Raw1: " + rawM.ch1 + "\nRaw2: " + rawM.ch2);
            default:
                break;
        }
 
        //if (msgBuffer.size() &amp;gt; maxBufferSize - 1) {
        if (index &amp;gt;= maxBufferSize) {
            index = 0;
            //Fixme
//            int i = 0;
//            for(Message mm : msgBuffer) {
//                Log.d(TAG, "check message msg.what = " + mm.what + " number = " + i);
//                i++;
//            }
            for (int i = 0; i&amp;lt;maxBufferSize; ++i) {
                Log.d(TAG, "Out: msg.what = " + msgBuffer[i].what + ", msg.when = " + msgBuffer[i].getWhen() + ", number = " + i);
            }
            // 儲存db資料
            if (OneOrTwo == 1) {
//                t1 = new SavingData(Buffer1);
//                while (t2 != null &amp;amp;&amp;amp; t2.myThread.isAlive()) ;
                //Buffer2 = Collections.synchronizedList(new ArrayList&amp;amp;lt;Message&amp;amp;gt;());
                Buffer2 = new Message[maxBufferSize];
                msgBuffer = Buffer2;
                OneOrTwo = 2;
            } else {
//                t2 = new SavingData(Buffer2);
//                while (t1.myThread.isAlive()) ;
                //Buffer1 = Collections.synchronizedList(new ArrayList&amp;amp;lt;Message&amp;amp;gt;());
                Buffer1 = new Message[maxBufferSize];
                msgBuffer = Buffer1;
                OneOrTwo = 1;
            }
        }
 
    }

在第34~36行，我們將message存放到Array中，然後馬上將Array的內容印出來檢查

當Array的內容儲存到一定的數量，我們再將Array所有的內容印出來再次檢查，如第84~86。Log的結果卻發現在84~86的傾印的內容有一大堆的message變成空值，這個問題抓了很久一直找不到解決的方法，是哪一個細節忽略掉了呢? 做成紀錄先

EventLog如下，line 1 ~ 100是存入容器時的log，line 101 ~ 200是批次列印時的結果。發現在批次列印時，容器內的message物件都不是原來的物件了(從msg.when推測出來)

如果改成每收到一個message就發動一個thread去做存檔的工作，一樣會發生message物件不見得問題，覺得是我忽略了某一個基礎的問題，唉~

@Override
public void handleMessage(Message msg) {
    switch (msg.what) {
        ...
        case TGDevice.MSG_RAW_DATA:
            Log.e(TAG, "In: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + msgCount++);
            new SavingData2(msg);
            break;
        case TGDevice.MSG_ATTENTION:
            Log.e(TAG, "In: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + msgCount++);
            new SavingData2(msg);
            SensingActivity.setAtt(String.valueOf(msg.arg1));
            SensingActivity.setp1(msg.arg1);
        case TGDevice.MSG_MEDITATION:
            Log.e(TAG, "In: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + msgCount++);
            new SavingData2(msg);
            SensingActivity.setMed(String.valueOf(msg.arg1));
            SensingActivity.setp2(msg.arg1);
            break;
        case TGDevice.MSG_BLINK:
            Log.e(TAG, "In: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + msgCount++);
            new SavingData2(msg);
            break;
        ...
        default:
            break;
    }
}

另外改成每收到一個message就發動一個thread去做存檔，因為thread會自己排程很難去控制他的順序，所以又會有後產生的message先存檔的問題，造成資料庫中的資料順序不對，可以看下面的log節錄，TGDeviceHandler產生的順序和SavingData Thread執行的順序。

修改程式碼，在thread中檢查是否有正確的接收到message物件。SavingData.java的程式碼如下

public class SavingData2 implements Runnable {
    private final String TAG = getClass().getSimpleName();
    Message msg;
    Thread myThread;
    private long counter;
    private static long threadCount = 0;
 
    public long getCounter() { return counter; }
    public static long getThreadCount() { return threadCount; }
 
    ReentrantLock lock = new ReentrantLock();
 
    SavingData2(Message msg) {
        this.msg = msg;
        this.counter = threadCount++;
        Log.i(TAG, "Out1: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + counter++);
        myThread = new Thread(this);
        myThread.start();
    }
 
 
    @Override
    public void run() {
        lock.lock();
        Log.i(TAG, "Out: msg.what = " + msg.what + ", msg.when = " + msg.getWhen() + ", msgCount = " + counter++);
        SensingActivity.getDB().insert(msg);
        lock.unlock();
    }
}

我分別在line 16跟25放一個Log來檢查物件，發現在建構子中的物件的確由傳遞進來，然而在run()執行緒中的物件則會變得不確定，如下面的log輸出，因此可能解決這個問題的方法是另外使用一個物件來存放message的內容，不要直接使用message物件。這算是系統的bug還是我的物件導向沒學好XD
