Android 6.0 更新导致 DB sqlite 在 init 期间崩溃

Question

我在应用程序类文件中创建数据库的代码可在数千台设备上运行，但最近我多次遇到崩溃，全部来自 android 6.0，因此它可能与新的 android 版本有关。此外，此崩溃仅在以下给定的 3 台设备上出现。请告知如何解决此问题..

设备:Canvas 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.SQLiteConnection.open(SQLiteConnection.java:207)

    at android.database.sqlite.SQLiteOpenHelper.getDatabaseLocked(SQLiteOpenHelper.java:223)
    at android.database.sqlite.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:163)

引用代码(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);
  }

在 db.getWritableDatabase() 发生崩溃。

请告知如何解决此问题。

我在 list 中添加“android.permission.WRITE_EXTERNAL_STORAGE”权限后仍然遇到问题，但仍然像上面一样崩溃。
