w/database( 497): reached max size compiled-sql statement cache database /data/data/com.android.email/databases/emailprovider.db; i.e., no space sql statement in cache: select _id attachment messagekey=996. please change sql statements use '?' bindargs, instead of using actual values

i want know behavior above error.

i mean android if maximum cache size exceeded? if tell implementation done, helpful.

this issue. message says all: "reached max size compiled-sql statement cache database"

basically emaill application using hardcoded values in queries. instead should use prepared statements in order cache prepared statements.

hope helps.
