Nous le constatons sur :

Versions Android : 5,6,7

Fabricants d'appareils : Lenovo, oneplus, samsung, motorola

Et, les appareils ne sont pas enracinés.

Après avoir cherché pendant un certain temps, je ne suis pas en mesure de trouver une cause (et un traitement) appropriée pour cela. J'ai parcouru ce question également mais il n'y a pas de solution.

Aidez-moi, s'il vous plaît.

Edit : Cela arrive pour beaucoup de nos utilisateurs, donc je ne peux pas aller dire à tout le monde de vérifier/installer webiew depuis le play store. Y a-t-il une meilleure solution pour cela ?

J'ai trouvé un problème probable ici. Comme nous savons que webview a été expédié comme une application séparée depuis Android 5.0, il se peut que au moment où ma vue est gonflée, le paquet de webview est mis à jour par le système d'exploitation et donc il ne peut pas trouver le paquet de webview pendant ces quelques instants. . Je sais que c'est un cas très limite mais

  • Comme je peux le constater, le crash se produit uniquement sur les appareils >= 5.0, ce qui confirme cette hypothèse.
  • il est très difficile de croire que tous ces appareils n'ont pas webview installé. En fait, j'ai essayé de désinstaller les paquets système et chrome de mon appareil mais l'application ne se plante toujours pas.

Voici donc ce que j'ai fait (solution bricolée mais qui évite les plantages) :

try {
        // the inflating code that's causing the crash 

    } catch (Exception e) {
        if (e.getMessage() != null && e.getMessage().contains("webview")) {
            // If the system failed to inflate this view because of the WebView (which could
            // be one of several types of exceptions), it likely means that the system WebView
            // is either not present (unlikely) OR in the process of being updated (also unlikely).
            // It's unlikely but we have been receiving a lot of crashes.
            // In this case, show the user a message and finish the activity
        }
    }

En gros, rien d'autre que de gérer cette exception. Ce n'est pas sorcier.

Veuillez vous référer à cette question.

Solution de rechange

try {
    super.setText(spannableStringBuilder, type);
} catch (Exception e) {
    // WebView is not installed in some devices by default, Linkify.MAP_ADDRESSES causes the exception
    if (e.getMessage().contains("webview")){
        setAutoLinkMask(Linkify.WEB_URLS | Linkify.EMAIL_ADDRESSES | Linkify.PHONE_NUMBERS);
    }
    super.setText(spannableStringBuilder, type);
}

Mon exception est

La pile de détails est :

la solution est

public class MyWebView extends WebView {

    @Override
    public void setOverScrollMode(int mode) {
        try {
            super.setOverScrollMode(mode);
        } catch (Exception e) {
            if (e.getMessage() != null && e.getMessage().contains("Failed to load WebView provider: No WebView installed")) {
                e.printStackTrace();
            } else {
                throw e;
            }
        }
    }
}

D'après les données du TextView SourceCode

if (mAutoLinkMask != 0) { ... if (Linkify.addLinks(s2, mAutoLinkMask)) { ... } }

La vue de texte avec android:autoLink appellera Linkify.addLinks (atteint la méthode de WebView enfin) et provoquer le crash.

Ainsi, nous pouvons supprimer le android:autoLink et réaliser d'autres moyens de résoudre le problème.
