Segnale fatale 11 (SIGSEGV) a 0x00000000 (codice = 1), thread 27830 (ple.myfragexample) - solo su Android 4.1.2

Question

Sto utilizzando FragmentActivity nella mia applicazione con diversi frammenti. Ognuno di questi frammenti contiene un'immagine e del testo con animazione. Quando l'utente scorre sullo schermo, il frammento cambia.

Ora ci sto lavorando da 10 giorni e ho testato FragmentActivity su diversi dispositivi con diverse versioni di Android. La ragione per cui mi sono bloccato su questo da ultimi 10 giorni è che sto ottenendo un incidente

Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 27830 (ple.myfragexample) 

Ora, questo errore si verifica solo quando prova il FragmentActivity su Android 4.1.2 particolare. Funzionerebbe bene su Android 2.3.3, 4.0.3, 4.0.4, 4.2 e persino 2.2. Il log degli errori è la seguente:

Ho cercato molto su internet e provato molte cose su questo, però, il lavoro dei miei Frammenti ottenuto più liscia su dispositivi con qualsiasi altra versione di Android, ma solo su Android 4.1.2. Ho anche provato ad usare Universal Image Loader, ma si blocca sempre con segnale fatale 11. Il log di errore che ottengo quando sto usando universale Immagine Loader è la seguente:

Ora, so che ci sono un sacco di domande con Fatal segnale anche 11 qui, ma sono preoccupato e confuso mentre sto ottenendo questo crash solo su Android 4.1.2 e non su altre versioni di Android.

Answer 1

Il mio problema è risolto ora. Ho appena ridimensionato le mie immagini dal mio team di grafica. Precedentemente stavo usando le immagini a risoluzione 1280x768, ma le ho ridotte a 800x480 e il crash non funziona più. Grazie per tutti i suggerimenti però.

Inoltre, credo che Jelly Bean (4.x) abbia un'interfaccia utente migliorata e quindi occupa più memoria per gestire l'interfaccia utente stessa rispetto alle versioni inferiori di Android, ed è per questo che non è stato in grado di gestire la gestione (ridimensionamento) le immagini più grandi.

Answer 2

Dai un'occhiata alla mia domanda:

Strange crash drawing on canvas on Android 4.0.3. A/libc: Fatal signal 11 (SIGSEGV)

forse è lo stesso problema. Il problema sorge quando provo a utilizzare un numero piccolo per la corsa o altre proprietà Paint.

setStrokeWidth(0.007f); 

mai risolto, suggerisco di scalare la tela e utilizzare i numeri più grandi.
