Android SQLite数据库：未知错误（代码14）：无法打开数据库

我正在制作一个应用程序，从另一个应用程序复制一个db文件，然后编辑db

当我尝试打开de SQLite db时，我得到一个错误：

android.database.sqlite.SQLiteCantOpenDatabaseException: unknown error (code 14): Could not open database

我在互联网上看到过很多不同的方法，但都没用

这是我的密码：

public class FirstRunService extends IntentService{
    /**
     * Creates an IntentService.  Invoked by your subclass's constructor.
     *
     * Service Used to name the worker thread, important only for debugging.
     */
    public FirstRunService() {
        super("Service");
    }
    String filesdir;
    SharedPreferences sp;
    @Override
    protected void onHandleIntent(Intent intent) {
        //Cargo SharedPreferences
        sp = this.getSharedPreferences("FirstRun", Context.MODE_PRIVATE);
        //Asigno filesdir
        filesdir = intent.getStringExtra("filesdir");
        //Subo XX
        Boolean XX = sp.getBoolean("XX",false);
        if(!XX) {
            uploadxxs(intent);
        }


    }

    protected void uploadXX (Intent intent){
        //Preparo
        SQLiteDatabase db;
        myFTP myftp = new myFTP();
        FTPClient client;

        //Copio la Base de datos

        RootTools.deleteFileOrDirectory(filesdir + "/XX.db", true);
        RootTools.copyFile("/data/data/com.XX/databases/XX.db", filesdir+"/xx.db",true,false);
        try {
            RootTools.getShell(true).add(cmd);
        } catch (TimeoutException e) {
            e.printStackTrace();
            Log.e("Root XX.db","Fallo");
            FirstRunAlarm.completeWakefulIntent(intent);
            stopService(intent);
        } catch (RootDeniedException e) {
            e.printStackTrace();
            Log.e("Root XX.db","Fallo");
            FirstRunAlarm.completeWakefulIntent(intent);
            stopService(intent);
        } catch (IOException e) {
            e.printStackTrace();
            Log.e("Root XX.db","Fallo");
            FirstRunAlarm.completeWakefulIntent(intent);
            stopService(intent);
        }
        //Edito db
           //Edito db
    File file = new File(filesdir+"/wa.db");
    if (file.exists()){
        Log.e("File","Existe");
        db = SQLiteDatabase.openDatabase(filesdir+"/wa.db", null,SQLiteDatabase.OPEN_READWRITE);//Error in this line
    }else{
        db = null;
        Log.e("File","No Existe");
    }
        db.execSQL("DROP TABLE android_metadata;");

首先检查数据库文件是否存在使用：

File file = new File(myPath);    
if (file.exists() && !file.isDirectory())

---

解决方法是创建一个类，然后直接从服务调用该类

阶级

---

在OpenDatabase之前添加：

file.setWritable(true);

---

尝试检查文件是否已创建或是否存在。。还可以在清单中添加写入外部存储权限添加的清单，以便您可以读取“我有权限”。尝试了if（file.exist）并且该文件存在。还有其他想法吗？你能参考一下吗？它说超级方法shud正确引用了路径。我们通常做的是创建一个扩展Sqliteopenhelper的类。。在其中，超级方法被调用。。。所以所有的uv复制都可以在那里完成，你所要做的就是使用这个类的obj从服务中调用它里面的一个方法。是的，你可以从中得到一个想法，而且我已经添加了一行出现相同错误的代码。文件exist返回TRUE

file.setWritable(true);
