the idea here know causing bug, can change course of program avoid condition wherein bug can occur. credible or official answer sought after , putting bounty of 200 on question once eligible.
in case occurs when doing memory intense operation, knowledge (naive might be) tells me has got pausing gc, (manual) call system.gc resolve things me?
how recover error? in loop reading 1 db table, address book , file 1 after other. these read values undergo calculation process , results stored in larger db. these statements in while loop, have put checks in try catch if any , not limited to error occurs. start next iteration of loop using continue statement in catch clause- neglecting record crash occurs. execution not guaranteed using method, crash can keep happening forcing subsequent records omitted.

i doing above process inside try catch wherein using transactions speed things. have implemented these transaction snippets @ opening of try block, start transaction , end them @ block , set them successful @ same place.
it seems samsung specific bug. has been reported to
- aosp issue tracker
- at samsung developer forum here , here
so far there not seem solution except updating android version (if got right).
