Syntax Error using Vacuum Into on Android

I'm trying to make a backup of a database in an Android application, and I was pointed to the VACUUM INTO query. However, when I try to call it, I get a syntax error around "INTO":
Caused by: android.database.sqlite.SQLiteException: near "INTO": syntax error (code 1 SQLITE_ERROR): , while compiling: VACUUM INTO 'Test'
The String itself:
String query = "VACUUM INTO 'Test'";
I've tried using double quotes, single quotes, different path names, .db, no file type, including and excluding the database name - always the same error.
Is INTO not supported on Android's implementation of SQLite?

SQLite query: between

I am using SQLit in my Android app, I want to search in my database.
my query and error is this :
Error Code : 1 (SQLITE_ERROR)
Caused By : SQL(query) error or missing database.
near "to": syntax error (code 1): , while compiling:
select * from informations where house_type = 'آپارتمانی' and room_count = '1' and (cost between 0 to 100000000) and (area between 0 to 1000)
anybody knows what is the problem ?

The syntax for the BETWEEN operator is test_expression BETWEEN low_expression AND high_expression. So change TO in AND.

SQLiteException syntax error unclear

I get
android.database.sqlite.SQLiteException: near "WHERE": syntax error (code 1): , while compiling: insert or replace into taeglich (datum, a, b, c, d) values ('29.4.2017', '10 ml f\n', '0.0', '0.0', '0.0') WHERE datum = '29.4.2017';
Do you see the syntax error?

Remove the WHERE clauses
insert or replace into taeglich VALUES ('29.4.2017', '10 ml f\n', '0.0', '0.0', '0.0');

React-Native: Async Storage no such table

At the opening of my app I'm trying to get some preferences via AsyncStorage.multiGet or AsyncStorage.getItem. Unfortunately the very first time I open the app, the SQLite table used by AsyncStorage in Android, doesn't exist. And so the app crashes. How should I handle the error to avoid having a red death screen.
FYI the exception thrown is :
no such table: catalystLocalStorage (code 1): , while compiling: INSERT OR REPLACE INTO catalystLocalStorage VALUES (?, ?);
Thanks

SQL Syntax Error Android

I am getting an SQL syntax error but I'm not quite sure why. This is the error code I am obtaining;
android.database.sqlite.SQLiteException: near "GCSE": syntax error (code 1): , while compiling: SELECT foreign_word,english_meaning,correct FROM vocab_words WHERE name = AQA GCSE Spanish Higher
Any suggestions to fix this - I don't know what the error is?

when the column's data type is string, its value should be wrapped with single quote.
SELECT foreign_word,english_meaning,correct
FROM vocab_words
WHERE name = 'AQA GCSE Spanish Higher'
