編輯：導入android.os.CancellationSignal不能在Android上得到解決ORMLite
誤差與4.48ORMLite版本出現。我回滾到4.45並且錯誤停止發生。
我實現了使用ORMLite爲Android在網站上方向下的數據庫。但是，任何時候我嘗試寫到數據庫中，我得到一個異常：

這是在IntentService子發生。以下是該類的一些相關代碼：
private DatabaseHelper databaseHelper;
static {
OpenHelperManager.setOpenHelperClass(DatabaseHelper.class);
}
public DatabaseHelper getHelper() {
if (databaseHelper == null) {
databaseHelper = OpenHelperManager.getHelper(this, DatabaseHelper.class);
}
return databaseHelper;
}
@Override
public void onDestroy() {
super.onDestroy();
if (databaseHelper != null) {
OpenHelperManager.releaseHelper();
databaseHelper = null;
}
}
我可以在我的代碼中導入android.os.CancellationSignal就好了。
我與版本4.48有同樣的問題。 – koso
謝謝你的同樣的問題而且我swings更低的版本 – topxebec
我也遇到過這樣的崩潰。剛剛切換到4.47，現在一切正常 – Robert
