HERE is the code that i'm using to parse

Is there any way you could use an SQLite database rather than an XML file for your data? — EboMike

I'm not sure if the parsing itself is causing it or the storing in the List<DbEntry> list simply becoming too big. If latter, try to directly push the data to the sqlite DB instead of storing it in the List<DbEntry>. May be less efficient, but with huge number of records maybe a better solution. Or cache 20-30 entries and flush them into the DB, clear the list and cache another 20-30 — Tseng

There are heap restrictions for android, read the XML data in chunks from your file and parse it conveniently

Ninja edit:

As per Tseng : Caching List<DbEntry> by reading 20-30 entries into it makes much more sense.
