sqlitedatabase update where clauses - android-sqlite

Question

i am getting a string category and address name from other class
what i need is to update categories table with specific address_id which is foreign key to address table. and address table contains a address_name.
So I am getting address_name from other class and i want to update categories table which specific address_id with given address_name and change its categories name to string category.
this is code that i have tried but it did not work, it does not gives error in android studio but it does not actually updates in the database.
public void updateData(String categories, String positionName){
ContentValues contentValues = new ContentValues();
contentValues.put("categories_name", categories);
Log.d(TAG, "updateData: " + categories );
database.update("categories", contentValues, "address_id = ?", new String[]{"(SELECT address_id FROM address WHERE address_name = " + positionName + ")"});
this is my address table
CREATE TABLE "address" (
"address_id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
"address_name" TEXT UNIQUE,
"lat" BLOB NOT NULL,
"lng" BLOB NOT NULL,
"date" NUMERIC);
and this is my categories table
CREATE TABLE "categories" (
"Categories_id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
"categories_name" TEXT NOT NULL DEFAULT 'place' CHECK(categories_name in ('place','home','work')),
"address_id" INTEGER NOT NULL UNIQUE,
FOREIGN KEY("address_id") REFERENCES "address"("address_id"));
