Fuite de mémoire Android sur la visualisation de texte – LeakCanary (la fuite peut être ignorée)

Je continue d'avoir la fuite de mémoire suivante, tel qu'indiqué par LeakCanary, lorsque je passe de mon écran d'accueil à l'activité principale. Je comprends qu'il s'agit d'une fuite attendue en raison d'une erreur dans le système d'exploitation Android, mais existe-t-il un moyen pour éviter cela (en définissant des spécificités de certains TextView quelque part?)

    À partir de AndroidExcludedRefs.java :

      // TextLine.sCached is a pool of 3 TextLine instances. TextLine.recycle() has had at least two // bugs that created memory leaks by not correctly clearing the recycled TextLine instances. // The first was fixed in android-5.1.0_r1: // https://github.com/android/platform_frameworks_base/commit // /893d6fe48d37f71e683f722457bea646994a10bf // The second was fixed, not released yet: // https://github.com/android/platform_frameworks_base/commit // /b3a9bc038d3a218b1dbdf7b5668e3d6c12be5ee4 // Hack: to fix this, you could access TextLine.sCached and clear the pool every now and then // (eg on activity destroy). 

    Étape 1: Access TextLine.sCached

     public static class Utils { private static final Field TEXT_LINE_CACHED; static { Field textLineCached = null; try { textLineCached = Class.forName("android.text.TextLine").getDeclaredField("sCached"); textLineCached.setAccessible(true); } catch (Exception ex) { ex.printStackTrace(); } TEXT_LINE_CACHED = textLineCached; } public static void clearTextLineCache() { // If the field was not found for whatever reason just return. if (TEXT_LINE_CACHED == null) return; Object cached = null; try { // Get reference to the TextLine sCached array. cached = TEXT_LINE_CACHED.get(null); } catch (Exception ex) { // } if (cached != null) { // Clear the array. for (int i = 0, size = Array.getLength(cached); i < size; i ++) { Array.set(cached, i, null); } } } private Utils() {} } 

    Étape 2: effacer la piscine

    Appelez Utils.clearTextLineCache() au besoin.
