What happens to an Android thread after the Activity that created it is destroyed?

Question

In my Android app, the main Activity will sometimes start a Thread to load data from a server. This thread modifies the app\'s database and edits some important files. AFAIK,

I might be digging out an old thread, but nobody mentioned one important thing.

Every time you use a database and modify multiple rows, you should make use of transactions to ensure that data stays valid in case of any kind of failure (which might be for example a termination of a thread, a socket exception etc.).

    try{
        db.beginTransaction(); 

        //Do whatever you need to do...    

        db.setTransactionSuccessful();
    }catch(SQLiteException e){
        Log.e("SQLite","Error while updating rows: " + e.getMessage());
    }finally{
        db.endTransaction(); //Commit (if everything ok) or rollback (if any error occured). 
        db.close(); //Close databse;
    }
