Answer 1

İlk onay ister:

İşte

benim kodudur

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

Answer 2

Bir sınıf oluşturarak, ardından bu sınıfı doğrudan hizmetten çağırarak çözüldü. Sınıf

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 3

OpenDatabase önce ekleyin:

file.setWritable(true);
