這個人不斷踢我的應用程序凍結，任何方法來解決這個問題？GC_CONCURRENT問題
這裏是我的代碼：

此問題的罪魁禍首就是這行代碼
case R.id.bKitchen:

SQLHandler kitchen = new SQLHandler(StartMoving.this);

kitchen.open();
String returnedRoom = kitchen.getRoom(currentRoom);
while (notavailroom) {
if (returnedRoom.equals(currentRoom)) {
inc++;
returnedRoom = kitchen.getRoom(currentRoom);
}else{
notavailroom = false;
kitchen.addRooms(currentMove, currentRoom);
roomName.setText(currentRoom);
Button b = new Button(StartMoving.this);
b.setText(currentRoom);
row.addView(b);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
addRooms.addView(row);
main.setVisibility(View.VISIBLE);
roomButtons.setVisibility(View.INVISIBLE);
}
}
kitchen.close();
} catch (Exception e) {
// TODO Auto-generated catch block
SQLHandler kitchen = new SQLHandler(StartMoving.this);
currentRoom = "Kitchen" + inc;
kitchen.open();
kitchen.addRooms(currentMove, currentRoom);
roomName.setText(currentRoom);
Button b = new Button(StartMoving.this);
b.setText(currentRoom);
row.addView(b);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
addRooms.addView(row);
main.setVisibility(View.VISIBLE);
roomButtons.setVisibility(View.INVISIBLE);
kitchen.close();
}
break;
時kitchen button是什麼，我基本上想要做的就是按它首先檢查數據庫，如果給出的按鈕文本存在於數據庫中，如果不存在，則默認名稱被賦予按鈕並保存到數據庫中，但如果名稱存在，則其他名稱將通過遞增給出int inc使名稱currentRoom = "kitchen " + inc;
這裏也用於處理數據庫
