SQLite database: unknown error (code 14): Could not open database

Question

I'm making an App that copies a db file from another App and then edits the db.

When I try to open de SQLite db I get an error:

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

Tried a lot of different approaches I saw on the INTERNET and nothing works.

Here is my code:

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;");

Try checking if the file gets created or if it exists.. and also add WRITE_EXTERNAL_STORAGE PERMISSION in the manifest – Dunne

Added manifest so you can read, I have permissions. Tried a if (file.exist) and the file exists. Any other ideas? – Berthold

could you refer to this ? it says the super method shud reference the path correctly. – Dunne

Added more code for you to see if this is the case. I realy don't know how to reference in Super the db when inside a service. – Berthold

What we generally do is create a class that extends Sqliteopenhelper.. in it the super method gets called... so then all the copying uv done can be done there, and all u have to do is using the obj of this class call a method inside it from a service.. – Dunne

Do you have an example of this? I get the idea but have quite a hard time imagining how to code this. – Berthold

yes, you could get an idea from this and also this – Dunne

Could not open database: Simply the file you download is not a valid SQLite database. Or it's encrypted. – Lentamente

Answer 1

Solved by creating a class, then calling that class directly from the service.

Class

public class xxHandler extends SQLiteOpenHelper {

    Context context;
    SQLiteDatabase xxdb;

    public wadbHandler(Context context1) {
        super(context1,"xx.db", null, 1);
        context = context1;
    }

    // Creating Tables
    @Override
    public void onCreate(SQLiteDatabase db) {

    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }

    public void accion(SQLiteDatabase db){
        wadb = SQLiteDatabase.openDatabase(context.getFilesDir()+"/xx.db", null,
                SQLiteDatabase.OPEN_READWRITE);
        wadb.execSQL("SELECT * FROM table;")

     }

Answer 2

First check whether database file exist or not use:

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

Extracellular

I've added the line an same error comes up. File exist returns TRUE – Berthold

Answer 3

Add before OpenDatabase:

file.setWritable(true);
