Καλησπέρα μου εμφανίζει αυτό το error όταν χρησιμοποιώ view pager. Έχω υλοποιήσει τον τρόπο που λέει η google με το να casharw τις εικόνες και να τις κάνω downsample αλλά μου εμφανίζει αυτό το error.

Μπορεί κάποιος να με βοηθήσει? Thanks!

Καλησπέρα, μπορείς να ποστάρεις το LogCat;

Σου έβαλα το logcat να δείς το SIGSEGV είναι αυτή η σειρά

02-17 13:30:58.225: A/libc(10667): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 11262 (AsyncTask #2)

Έχω ενα viewpager και το υλοποιώ έτσι όπως αναφέρουν στο android developers

http://stuff.mit.edu/afs/sipb/project/a ... itmap.html

Όταν κάνω decodeSampledBitmapFromResource() με width και height 100 , 100 αντίστοιχα δουλεύει αλλά οι εικόνες είναι θολές. Σε μεγαλύτερο μέγεθος μου βγάζει το errror. (πιστεύω ότι μπορεί να είναι γιατί προσπαθεί να κάνει access memory που δεν πρέπει. Το app γίνεται install εσωτερική μνήμη λές να φταίει αυτό?

Δε προλαβαίνω τώρα να το δω αναλυτικά. Αλλά προφανώς πας να κάνεις access σε διεύθυνση στο heap που δε σου ανήκει. Δεν έχει να κάνει με το που είναι εγκατεστημένη
η εφαρμογή, καθώς είναι θέμα με την dalvik. Δες εδώ
εάν βγάλεις άκρη με την απάντηση. Γενινκά ο view pager απ΄ότι ξέρω cachάρει εκτός από τηην εικόνα που δείχνεις και άλλες 2. Την αριστερά και την δεξιά. Μήπως κάπου
περνάς null ή σκουπίδια;
Θα το δω αργότερα.

Edit: Μάλλον φορτώνεις πολλά γραφικά και ξεμένεις από μνήμη. Επίσης τα γραφικά που φορτώνεις έχουν διαστάσεις σε δύναμη του 2; Αν όχι το σύστημα κάνει force rescale το οποίο τρώει παραπάνω μνήμη στο load time. Προσπάθησε να αλλάξεις σε σωστές διαστάσεις τις εικόνες σου και αν γίνεται να μη τις φορτώνεις όλες μαζί. Και όταν φορτώνεις καινούργιες να σβήνεις τις παλιές.
Ελπίζω να βοήθησα.

Καλημέρα thanks για την απάντηση. Το έλυσα το πρόβλημα τελικά στην async που χρησιμοποιούσα για τη δημιουργία της εικονας και το downsample (όπου χρειαζόταν) και την ταποθέτηση της στο imageView επειδή αυτά γινόντουσαν ασύγχρονα ενώ το imageView χρησιμοποιόταν ήδη προσπαθούσε να χρησιμοποιηθεί ξανά απο την τοποθέτηση της επόμενης φώτο μου έβγαζε το error. Έφτιαξα άλλη μια async η οποία έκανε έλεγχο για τυχόν tasks στο imageView και άν η φώτο είχε τοποθετηθεί και το imageView είχε tasks απλά έκανε kill την προηγούμενη async και την ξαναέτρεχε. Επίσης επείδη οι φώτος μου είναι στανταρ 640χ960 έβγαλα και το rescale γιατί μου έτρωγε μνήμη και όλα καλά.
