为什么在Looper.getMainLooper()中接收垃圾数据)

Question

在Looper.getMainLooper(

public class A1Service extends PresentationService implements
Runnable {
switch(dataId) {
case 0x2b:
Log.d("AAA", "speed_data==>" + speed  +"speed_id:--------"+ Data[0]);//here receiving properdata 
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
Log.d("AAA", "speed_data==>" + speed  +"speed_id:"+ Data[0]);//here receiving junk data         
}
});
break;
case 0x40:
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
Log.d("AAA", "rpm_data==>" + rpm  +"id:--------"+ Data[0]);//here receiving junk data                                        
}
});
break;
Logcat:
speed_data==>537     speed_id:64
speed_data==>17     speed_id:--------43
speed_data==>538     speed_id:64
speed_data==>18     speed_id:--------43
speed_data==>1     speed_id:88
speed_data==>19     speed_id:--------43
speed_data==>1     speed_id:90
speed_data==>20     speed_id:--------43
speed_data==>1     speed_id:92
speed_data==>21     speed_id:--------43
speed_data==>25     speed_id:94
speed_data==>22     speed_id:--------43

我的问题是使用AsyncTask解决的。

像

private class CustomTask extends AsyncTask<Void, Void, Void> {
protected Void doInBackground(Void... param) {
return null;
}
protected void onPostExecute(Void param) {
case 0x2b:
Log.d("AAA", "speed_data==>" + speed  +"speed_id:--------"+ Data[0]);//here receiving properdata 
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
Log.d("AAA", "speed_data==>" + speed  +"speed_id:"+ Data[0]);//here receiving junk data         
}
});
break;
case 0x40:
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
Log.d("AAA", "rpm_data==>" + rpm  +"id:--------"+ Data[0]);//here receiving junk data                                        
}
});
break;
