我有两款Android手机，分别是Sumsung Galaxy s3（Android 4.4.2，Kitkat，API19）和Nexus 6p（Android 6.0.1，Marshmallow，API23）。 这是我的DatabaseHelper课程：

public class DatabaseHelper extends SQLiteOpenHelper {

private static final String LOG_TAG = DatabaseHelper.class.getSimpleName();

public DatabaseHelper(Context context) {
    super(context, DatabaseContract.DATABASE_NAME, null, DatabaseContract.DATABASE_VERSION);
    Log.v(LOG_TAG, "DatabaseHelper() executed.");
}

@Override
public void onCreate(SQLiteDatabase db) {
    Log.v(LOG_TAG, "onCreate() executed.");
    Log.v(LOG_TAG, DatabaseContract.PerformanceTable.PERFORMANCE_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.PlayerTable.PLAYER_TABLE_CREATION);
    Log.v(LOG_TAG, DatabaseContract.TeamTable.TEAM_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt3Table.Pt3_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt2Table.Pt2_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt1Table.Pt1_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.StealTable.STEAL_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.BlockTable.BLOCK_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.OffRebTable.OFFREB_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.DefRebTable.DEFREB_TABLE_CREATION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.AssistTable.ASSIST_TABLE_CREATION_QUERY);

    db.execSQL(DatabaseContract.PerformanceTable.PERFORMANCE_TABLE_CREATION_QUERY);
    db.execSQL(DatabaseContract.PlayerTable.PLAYER_TABLE_CREATION);
    db.execSQL(DatabaseContract.TeamTable.TEAM_TABLE_CREATION_QUERY);
    db.execSQL(DatabaseContract.Pt3Table.Pt3_TABLE_CREATION_QUERY);
    db.execSQL(DatabaseContract.Pt2Table.Pt2_TABLE_CREATION_QUERY);

    db.execSQL(DatabaseContract.AssistTable.ASSIST_TABLE_CREATION_QUERY);
    db.execSQL(DatabaseContract.TurnoverTable.TURNOVER_TABLE_CREATION_QUERY);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    Log.v(LOG_TAG, "onUpgrade() executed.");

    Log.v(LOG_TAG, DatabaseContract.PerformanceTable.PERFORMANCE_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.PlayerTable.PLAYER_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.TeamTable.TEAM_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt3Table.PT3_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt2Table.PT2_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.Pt1Table.PT1_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.StealTable.STEAL_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.BlockTable.BLOCK_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.OffRebTable.OFFREB_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.DefRebTable.DEFREB_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.AssistTable.ASSIST_TABLE_DELETION_QUERY);
    Log.v(LOG_TAG, DatabaseContract.TurnoverTable.TURNOVER_TABLE_DELETION_QUERY);

    db.execSQL(DatabaseContract.TeamTable.TEAM_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.PlayerTable.PLAYER_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.Pt3Table.PT3_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.Pt2Table.PT2_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.Pt1Table.PT1_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.StealTable.STEAL_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.BlockTable.BLOCK_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.OffRebTable.OFFREB_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.DefRebTable.DEFREB_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.AssistTable.ASSIST_TABLE_DELETION_QUERY);
    db.execSQL(DatabaseContract.TurnoverTable.TURNOVER_TABLE_DELETION_QUERY);
    onCreate(db);
}
}

所涉及的每个安装都是干净安装：卸载应用程序并安装它，因为它是新的 在API19（Sumsung Galaxy 3）上，onCreate()中的DatabaseHelper方法在应用启动时执行，请参阅相关日志：

但是，在Google Nexus 6P上，即使执行或创建onCreate()，也未执行DatabaseHelper方法。请参阅相关日志：

09-19 14:59:14.178 15504-15504/com.leontheprofessional.bballscoreboard V/DatabaseHelper: DatabaseHelper() executed.

这里只有一条线。

更奇怪的是：
从Nexus6P获取db文件后，我发现这些表是先前设计的：只有3个在那里，并且列比当前列少得多。当我尝试通过player将ContentProvider对象插入数据库时​​，我收到SQLiteException错误说＆＃34;没有这样的列...＆＃34;
卸载之前的应用程序后，每个安装都是干净。
卸载后，我尝试备份此应用程序的数据（使用package.name）以查看是否仍然保留了数据库残留，但是生成的back_up_data.ab文件中没有一个项目。 我尝试在Nexus6P上运行命令adb uninstall <yourpackagename>，但它是一样的：一旦安装了应用程序，保留了以前版本的数据库，onCreate（）方法永远不会被执行。
出了什么问题？
