应用程序在设备上运行时如何获取Sqlite数据库文件？

String dbPath = context.getDatabasePath("your_database_name.db").getAbsolutePath();

let fileManager = FileManager.default
let urls = fileManager.urls(for: .documentDirectory, in: .userDomainMask)
let documentDirectory = urls[urls.count - 1]
let path = documentDirectory.appendingPathComponent("your_database_name.db").path

SQLiteDatabase db = SQLiteDatabase.openDatabase(dbPath, null, SQLiteDatabase.OPEN_READWRITE);

let db = try? Connection(path)

Cursor cursor = db.rawQuery("SELECT * FROM your_table_name", null);

let statement = try? db.prepare("SELECT * FROM your_table_name")

db.close();

db.close()
