Android没有这样的表例外

我开始了一个新项目。在这里，我想将数据保存到数据库中，但由于某些原因，我总是会遇到此异常。希望你能帮助我。 也许重要的是要知道所有这些都是在一个片段中运行的

04-04 20:06:39.535  20756-20756/de.company.packageE/SQLiteLog﹕ (1) no such table: trailinfo

至少在这里，我想与数据库进行交互：

TrailInfoDbHelper dbTrailInfoHelper;
    private SQLiteDatabase dbTrailInfo;         // DB for Trail Info

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }

        dbTrailInfoHelper = new TrailInfoDbHelper(getActivity());
        dbTrailInfo = dbTrailInfoHelper.getWritableDatabase();      // WritableDatabase for the TrailInfo

    }

private void trackingStart() {

        // Getting start Values for new Trail
        long startTime = c.getTime().getTime();        // The Time when the Trail was started

        // Write the Data into ContentValue
        ContentValues values = new ContentValues();
        values.put(TrailInfo.COLUMN_NAME_TRAILINFO_STARTZEIT, startTime);

        // Store Data in Database and recieve the TrailID
        Id = dbTrailInfo.insert(TrailInfo.TABLE_NAME, null, values);
        Toast.makeText(getActivity(), "New ID: " + String.valueOf(trailId), Toast.LENGTH_SHORT).show();

    }

定义所有静态的代码

import android.provider.BaseColumns;

public class TrailContract {

    public TrailContract() {}

    public static abstract class TrailPoints implements BaseColumns {
        public static final String TABLE_NAME = "trailpoints";
        public static final String COLUMN_NAME_TRAILPOINTS_TRAILID = "trailid";
        public static final String COLUMN_NAME_TRAILPOINTS_TIME = "time";
        public static final String COLUMN_NAME_TRAILPOINTS_LAT = "lat";
        public static final String COLUMN_NAME_TRAILPOINTS_LNG = "lng";
    }

    public static abstract class TrailInfo implements BaseColumns {
        public static final String TABLE_NAME = "trailinfo";
        public static final String COLUMN_NAME_TRAILINFO_SUCHHUND = "suchhund";
        public static final String COLUMN_NAME_TRAILINFO_AUSLEGEZEIT = "auslegezeit";
        public static final String COLUMN_NAME_TRAILINFO_STARTZEIT = "startzeit";
        public static final String COLUMN_NAME_TRAILINFO_ENDZEIT = "endzeit";
        public static final String COLUMN_NAME_TRAILINFO_ADRESSE = "adresse";
        public static final String COLUMN_NAME_TRAILINFO_ORT_LAT = "ort_lat";
        public static final String COLUMN_NAME_TRAILINFO_ORT_LNG = "ort_lng";
        public static final String COLUMN_NAME_TRAILINFO_RUNNER = "runner";
        public static final String COLUMN_NAME_TRAILINFO_BEGLEITPERSON = "begleitperson";
        public static final String COLUMN_NAME_TRAILINFO_TRAILLEGER = "trailleger";
        public static final String COLUMN_NAME_TRAILINFO_TRAILLEGER_DETAILS = "trailleger_details";
        public static final String COLUMN_NAME_TRAILINFO_GERUCHSTRAEGER = "geruchstraeger";
        public static final String COLUMN_NAME_TRAILINFO_GERUCHSTRAEGER_DETAILS = "geruchstraeger_details";
        public static final String COLUMN_NAME_TRAILINFO_ABGANG = "abgang";
        public static final String COLUMN_NAME_TRAILINFO_UMGEBUNG = "umgebung";
        public static final String COLUMN_NAME_TRAILINFO_WITTERUNG = "witterung";
        public static final String COLUMN_NAME_TRAILINFO_TEMPERATUR = "temperatur";
        public static final String COLUMN_NAME_TRAILINFO_BODEN = "boden";
        public static final String COLUMN_NAME_TRAILINFO_UEBUNGSSCHWERPUNKTE = "uebungsschwerpunkte";
        public static final String COLUMN_NAME_TRAILINFO_UEBUNGSSCHWERPUNKTE_DETAILS = "uebungsschwerpunkte_details";
        public static final String COLUMN_NAME_TRAILINFO_SCHWERPUNKT_BEWAELTIGT = "schwerpunkt_bewaeltigt";
        public static final String COLUMN_NAME_TRAILINFO_MOTIVATION_DES_HUNDES = "motivation_des_hundes";
        public static final String COLUMN_NAME_TRAILINFO_TEAMARBEIT = "teamarbeit";
        public static final String COLUMN_NAME_TRAILINFO_BLIND = "blind";
        public static final String COLUMN_NAME_TRAILINFO_LAENGE = "laenge";
    }

}

你试过其他类似问题的解决方案吗？我把代码贴在上面@Der定义的地方Golem@Selvin是的，我尝试了我找到的所有解决方案，但没有一个有效公共静态最终int数据库_VERSION=1。。。我不这么认为。。。同时写下你试图解决的问题。。。类似的问题在一周内被问了10次，试图通过增加数据库版本、重新安装应用程序和在活动中初始化数据库来解决。但如果我是对的，则不会创建数据库，因为不会调用OnCreate
