Android 6.0更新导致在init期间DB sqlite崩溃

我在应用程序类文件中创建@L_801_1@的代码正在处理成千上万的设备,但最近我遇到崩溃,很多次,都来自 android 6.0,所以它可能与新的 Android版本有关.此次崩溃只发生在下面给出的3台设备上.请告知如何解决这个问题..

设备：
画布A1(AQ4501_sprout),Dream Uno(Mi-498_sprout),Sparkle V(Sparkle_V_sprout)

崩溃日志：

Caused by: android.database.sqlite.sqliteCantOpenDatabaseException: unkNown error (code 14): Could not open database

    at android.database.sqlite.sqliteOpenHelper.getWritableDatabase(sqliteOpenHelper.java:163)

参考代码(崩溃发生在db.getWritableDatabase())：

//Application class
public class MyApp extends Application {

 @Override
 public void onCreate() {
    super.onCreate();
    dataBaseInit();
 }

 private void dataBaseInit() {
    db = new MyDatabase(getApplicationContext());

    // This will open an reference to database
    dataBaseRef = db.getWritableDatabase();
 }
}

//Database class
public class MyDatabase extends sqliteOpenHelper {

  // All Static variables
  // Database Version
  private static final int DATABASE_VERSION = 1;

  // Database Name
  private static final String DATABASE_NAME = "myDatabase";

  public MyDatabase(Context context) {
     super(context,DATABASE_NAME,null,DATABASE_VERSION);
  }

}

崩溃发生在db.getWritableDatabase().

请告知如何解决这个问题.
