java - Android 6.0 上的 Android java.lang.OutOfMemoryError

Question

所以我在 Play 商店上有这个应用程序，它可以帮助人们清理手机，并且我收到了一些错误消息，当人们单击“清理”按钮时，应用程序崩溃并且由于内存不足错误。这是错误消息:

这是错误所在的类:

task = new AsyncTask<Void, Integer, List<AppInfo>>() {
            private int mAppCount = 0;//(SoftwareManageFragment.java:127)

@Override
            protected List<AppInfo> doInBackground(Void... params) {
                PackageManager pm = mContext.getPackageManager();
                List<PackageInfo> packInfos = pm.getInstalledPackages(0);
                publishProgress(0, packInfos.size());
                List<AppInfo> appinfos = new ArrayList<AppInfo>();
                for (PackageInfo packInfo : packInfos) {
                    publishProgress(++mAppCount, packInfos.size());
                    final AppInfo appInfo = new AppInfo();
                    Drawable appIcon = packInfo.applicationInfo.loadIcon(pm);//(SoftwareManageFragment.java:139)
                    appInfo.setAppIcon(appIcon);

                    int flags = packInfo.applicationInfo.flags;

                    int uid = packInfo.applicationInfo.uid;

                    appInfo.setUid(uid);

                    if ((flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
                        appInfo.setUserApp(false);//系统应用
                    } else {
                        appInfo.setUserApp(true);//用户应用
                    }
                    if ((flags & ApplicationInfo.FLAG_EXTERNAL_STORAGE) != 0) {
                        appInfo.setInRom(false);
                    } else {
                        appInfo.setInRom(true);
                    }
                    String appName = packInfo.applicationInfo.loadLabel(pm).toString();
                    appInfo.setAppName(appName);
                    String packname = packInfo.packageName;
                    appInfo.setPackname(packname);
                    String version = packInfo.versionName;
                    appInfo.setVersion(version);
                    try {
                        mGetPackageSizeInfoMethod.invoke(mContext.getPackageManager(), new Object[]{
                                packname,
                                new IPackageStatsObserver.Stub() {
                                    @Override
                                    public void onGetStatsCompleted(PackageStats pStats, boolean succeeded) throws RemoteException {
                                        synchronized (appInfo) {
                                            appInfo.setPkgSize(pStats.cacheSize + pStats.codeSize + pStats.dataSize);

                                        }
                                    }
                                }
                        });
                    } catch (Exception e) {
                    }

                    appinfos.add(appInfo);
                }
                return appinfos;
            }

由于我只是一名初级开发人员，所以我不确定问题可能是什么。遇到此错误的特定手机使用的是 Android 6.0。我们将非常感谢帮助。非常感谢。

我认为这不是主要问题。您应该检查内存监视器是否存在内存不足异常。首先打开出现错误的Activity，然后按返回按钮检查是否有泄漏。
对于此异常，您可以采取一些措施。
在 Android list 中，您应该在应用程序标记下附加 largeheap = true。
您可以通过配置加载位图或可绘制文件并降低其空间
