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() > maxBufferSize - 1) {
if (index >= 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<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 && t2.myThread.isAlive()) ;
//Buffer2 = Collections.synchronizedList(new ArrayList<Message>());
Buffer2 = new Message[maxBufferSize];
msgBuffer = Buffer2;
OneOrTwo = 2;
} else {
// t2 = new SavingData(Buffer2);
// while (t1.myThread.isAlive()) ;
//Buffer1 = Collections.synchronizedList(new ArrayList<Message>());
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)

[補充]
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。

[補充2]
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
