在Chrome 90中，Google 发布了一个名为'Tab Freeze”的功能，用于暂停活动标签页以减少系统资源使用。但是，这可能会导致 Android 应用程序挂起，因为 Chrome 的进程获取了所有可用的系统资源，而其他进程则变得无法响应。

为了解决这个问题，我们可以使用以下代码示例，在您的 Android 应用程序中设置一个选项来禁用 Chrome 的'Tab Freeze”功能：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) { String freezedPackageName = "com.android.chrome"; String freezedClassName = "com.google.android.apps.chrome.Main"; // 禁用 Chrome 的冻结选项 PackageManager pm = getPackageManager(); PackageManager.NameNotFoundException e = null; for (String packageStr : pm.getPackagesForUid(Binder.getCallingUid())) { try { PackageInfo pi = pm.getPackageInfo(packageStr, PackageManager.GET_ACTIVITIES); if (pi == null || pi.activities == null) { continue; } for (ActivityInfo activityInfo : pi.activities) { if (activityInfo == null) { continue; } String className = activityInfo.name; if (freezedPackageName.equals(pi.packageName) && freezedClassName.equals(className)) { RestrictedLockUtilsInternal.setDeviceOwner(getBaseContext(), null); RestrictedLockUtilsInternal.checkIfRestrictionEnforced(getBaseContext(), UserManager.DISALLOW_APPS_CONTROL, Binder.getCallingUid()); // 禁用 Chrome 的冻结选项 UserHandle userHandle = UserHandle.of(UserHandle.getCallingUserId()); DevicePolicyManager DPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE); String frozenKey = "tab_management_freeze_threshold"; String packageName = freezedPackageName; DPM.setUserRestriction(userHandle, UserManager.DISALLOW_APPS_CONTROL); DPM.addUserRestriction(userHandle, UserManager.DISALLOW_APPS_CONTROL); // 禁用 Chrome 的冻结选项 String restriction = "home_launchable_apps"; ArrayList launchableAppList = new ArrayList(); launchableAppList.add(packageName); UserHandle appRestrictionUser = userHandle; UserHandle appRestrictionUserHandle = appRestrictionUser; Bundle bundle = new Bundle(); bundle.clear(); bundle.putStringArrayList(restriction, launchableAppList); mUserManager.setApplicationRestrictions(packageName, bundle, appRestrictionUserHandle); return; } } } catch (PackageManager.NameNotFoundException ignored) {} } }
