MapFragment API di Google Maps v2 Errore di memoria insufficiente/perdita di memoria

Question

Ho letto un numero di post simili negli ultimi giorni, ma nessuno che risponda specificamente a questo problema. Inizio a ottenere un problema con OOM dopo ~ 2 minuti di panoramica e zoom aggressivi con la mappa ibrida. L'app sembra anche conservare la memoria dopo l'arresto perché richiede meno tempo per raggiungere OOM dopo il primo errore. Ho ridimensionato il codice solo per un'attività con MapFragment e ancora ottengo la stessa OOM. Ho usato DDMS e MAT per provare e isolare il problema, oltre ad aggiungere android:largeHeap="true" che ritarda solo l'OOM. Il riorientamento dello schermo non è un problema perché sto impostando android:screenOrientation="portrait" nel mio manifest. Qualsiasi aiuto sarebbe apprezzato.

Aggiornamento 2014/08/25: This is supposed to be fixed back in May 2013?

Aggiornamento 2014/09/06: Ancora senza successo, l'unica opzione è quella di utilizzare buona Normal invece di Hybrid. GC sembra essere in grado di tenere il passo senza le immagini.

Answer 1

provare la mappa di chiamata onPausa, onResume, onLowMemory nei metodi Frammento corrispondenti.

Answer 2

Mi sono imbattuto in questo problema cercando di eseguire un'applicazione in modalità demo per alcune ore alla volta. Non importa cosa ho provato, dopo 30 minuti, vedrei questo crash senza un report di stack leggibile.

Ho provato molte cose diverse ma questa era l'unica cosa che ha funzionato per me. Non è una correzione per il bug della mappa, ma ha impedito alla mia app di bloccarsi:

<application 
    ... 
    android:largeHeap="true">
