How to openDatabase at external SD card in Android P (API 28)?

The code is over here : Unable to open database in Android Pie (Android 9)

The Android P(API 28) is not valid for SQLite Database files that are located in a custom path in external SD card.

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    MySQLiteOpenHelper helper = new MySQLiteOpenHelper();
    SQLiteDatabase database = helper.getReadableDatabase();
    myPath = database.getPath();
} else {
    String DB_PATH = Environment.getDataDirectory() + "/data/my.trial.app/databases/";  
    myPath = DB_PATH + dbName;
}
checkDB=SQLiteDatabase.openDatabase(myPath,null,
SQLiteDatabase.OPEN_READWRITE);
checkDB.disableWriteAheadLogging();

I want a method that is similar to:

SQLiteDatabase.openDatabase(custom_path, null,SQLiteDatabase.OPEN_READWRITE)
