Я хочу создать базу данных из SDCard, используя SQLiteCipher, но не дает мне обновленную дату и время из ExternalStorage / RemovableSDCard в Device File Explorer.
DBHelpers.Java
public class DBHelpers extends SQLiteOpenHelper {
private static DBHelpers instance;
public static final int DATABASE_VERSION = 1;
public static final String DATABASE_NAME = "Data.db";
private static final String TEXT_TYPE = " TEXT";
private static final String SQL_CREATE_ENTRIES = ...;
private static final String SQL_DELETE_ENTRIES =
"DROP TABLE IF EXISTS " + ...;
public DBHelpers(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
static public synchronized DBHelpers getInstance(Context context) {
if (instance == null) {
instance = new DBHelpers(context);
}
return instance;
}
public void onCreate(SQLiteDatabase db) {
db.execSQL(SQL_CREATE_ENTRIES);
}
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL(SQL_DELETE_ENTRIES);
onCreate(db);
}
MainActivity.java
SQliteDatabase database;
SQLiteDatabase.loadLibs(getContext());
String password = "password";
String path = "/storage/sdcard1/";
database = SQLiteDatabase.openOrCreateDatabase(path+"Data.db",password,null);
