You can simply use sql query to delete.

public void delete(String id) { db.execSQL("delete from "+TBL_NAME+" where Google='"+id+"'"); } 

In your query you are passing null in place of whereArgs

db.delete(table, whereClause, whereArgs) 

It should be like this

db.delete(TBL_NAME, "Google=?", new String[]{Integer.toString(id)}); 

Try this

public boolean favoriteDelete(int id) { return db.delete(DATABASE_TABLE, KEY_ROWID + "=" + id, null) > 0; } 

database.delete("tablename", "column_name=?", new String[] {Integer.toString(id)}); 

• the where condition values should be given as a string array

It's better to use placeholders than string manipulation. Ok for int's but as soon as you put a string in there things will go wrong.

String where = COLUMN_NAME_ADDRESS + " = ?"; String[] whereArgs = { String.valueOf(address) }; SQLiteDatabase db = mDbHelper.getWritableDatabase(); db.delete(TABLE_NAME_DEVICES, where, whereArgs); 

add single quotes in your where clause...

return database.delete("FavoriteData", "Goggle" + "='" + id+"'", null) > 0;
