What do you mean it was created on iOS? Could you try opening it with an empty password, maybe the db you are using is not encrypted?
Also it would be helpful to know the device and Android version you are using.

[YingW1012]

The password is right

The encrypted database is created with IOS app

Can open with SQLite studio(an app on Mac OS)

It was tested using the Android emulator

The API used is 30

[davidmartos96]

Is it a database that you copy from assets? Can I see the code where you do that?
What I meant with the DB being created on iOS is, how did you extract it from the app storage to now open it on Android or in Sqlite Studio

[YingW1012]

Using file browsing tool directly

Copy dB from iPhone app document directory

Put it in the corresponding directory of Android simulator

Then open it from the flutter project

Directory documentsDir = await getApplicationDocumentsDirectory();
String documentsPath = documentsDir.path;
String path = '$documentsPath/xxxx.db';
print(path);
var db = await openDatabase(
path,
// version: 1,
password: 'XXXX',
readOnly: true,
// onCreate: (Database db, int version) async {},
onConfigure: (db) async {},
onOpen: (db) async {
print("open db");

    var response = await db.rawQuery("SELECT name FROM sqlite_master WHERE type = 'table'");

    response.forEach((element) {
      print(element.toString());
    });
  },
);

Now that I see the code, it reminds me of an issue I had on my app long ago for using readOnly. Can you try disabling the readOnly?
Unfortunately the error is not very helpful here. If that doesn't work the next best thing you can do is create a reproducible example with a dummy database with the password you like so that I can try it.

[YingW1012]

I found the problem

The DB can be opened by placing it in the databases folder

That's odd. I have some code that opens a database in a temporary directory and it works correctly.
