i tried to open a data produced by another application

so i did it this way

myDB.create(path, 1, null);

myDB.open(path, null);

but the results was NullPointerException

what should i do ?

i know this.createDatabase(MY_DATABASE_NAME, 1, MODE_PRIVATE, null);

myDB = this.openDatabase(MY_DATABASE_NAME, null);

could work

why ?

what's difference?
