Android SIGSEGV sur Nexus 7 dans libskia près de SkCanvas :: drawPosText -> AutoDrawLooper :: next (SkDrawFilter :: Type) +96

Question

J'ai récemment commencé à obtenir ce SIGSEGV dans notre application et j'essaie de comprendre la cause ou un solution de contournement. Notre application est Java seulement, nous n'utilisons pas le NDK donc nous ne corrompons pas la mémoire nous-mêmes.

C'est un stock Nexus 7 en cours d'exécution 4.2.2

Le bug est intermittent mais a toujours SkCanvas :: drawPosText dans la pile (un couple plein de décharges sont pile ci-dessous):

backtrace: 
    #00 pc 01010200 <unknown> 
    #01 pc 0005ce24 /system/lib/libskia.so (AutoDrawLooper::next(SkDrawFilter::Type)+96) 
    #02 pc 0005e320 /system/lib/libskia.so (SkCanvas::drawPosText(void const*, unsigned int, SkPoint const*, SkPaint const&)+152) 

Nous fait un changement récent qui rend le rendu de texte plus fréquent aux bitmaps qui sont utilisés en tant que textures OpenGL (rendu de texte sur le thread GL je pense), peut-être que cela est en quelque sorte lié?

btw juste une question générale - est-il un moyen de comprendre quelle méthode Java déclenche cet appel? Je vois divers dvmInterpret dans la pile mais je ne sais pas s'il existe un moyen de savoir quel code est en cours d'exécution.

Exemple d'erreur décharge n ° 1:

Answer 1

Résolu! Le problème était que le thread UI et le thread GL utilisaient le même objet Paint. Je me suis synchronisé pour éviter les conflits et le problème a été résolu.

Answer 2

J'ai eu le même problème sur le téléphone OEM chinois sans nom. Grâce à l'indice de mwk, j'ai pu identifier le problème dans l'une des instances de Paint qui a été mise à jour [.setColor (..); .setShadowLayer (..); .setTextSize (..)] par thread non-UI.

Je l'ai fixé en créant wrapper thread-safe qui instancie un nouvel objet Peinture à chaque fois que l'un des attributs est nécessaire pour changer:

import android.graphics.Paint; 
import android.graphics.Typeface; 

import com.google.common.base.Preconditions; 

public class ThreadSafePaint { 

    private Paint delegate; 

    public ThreadSafePaint(Paint delegate) { 
     this.delegate = Preconditions.checkNotNull(delegate); 
    } 

    public Paint getPaint() { 
     return delegate; 
    } 

    public void setAntiAlias(boolean aa) { 
     delegate = new Paint(delegate); 
     delegate.setAntiAlias(aa); 
    } 

    public Typeface setTypeface(Typeface typeface) { 
     delegate = new Paint(delegate); 
     return delegate.setTypeface(typeface); 
    } 


    public void setShadowLayer(float radius, float dx, float dy, int color) { 
     delegate = new Paint(delegate); 
     delegate.setShadowLayer(radius, dx, dy, color); 
    } 


    public int getColor() { 
     return delegate.getColor(); 
    } 

    public void setColor(int color) { 
     delegate = new Paint(delegate); 
     delegate.setColor(color); 
    } 

    public void setTextSize(float textSize) { 
     delegate = new Paint(delegate); 
     delegate.setTextSize(textSize); 
    } 

}
