android - 打开小部件选择器时系统设置强制关闭

Question

我的用户报告当他们尝试使用我的应用程序(不是启动器应用程序)选择一个小部件时发生崩溃。我使用的是标准小部件选择器代码，它始终可以在所有设备上正常工作，LG G2 和 LG G3 除外。

我发现了一些类似的问题，但它们都指的是 Android 2.1 遭受的崩溃，该崩溃已通过空数据解决方法解决(已在我的代码中实现)。

还使用了 alternative way在没有官方选择器的情况下获取小部件 - 这可以工作，但需要该应用程序是具有 BIND_APPWIDGET 权限的系统应用程序。

有没有人也遇到过这个问题，也许找到了解决方法或解决方案？

谢谢

代码如下:

public static void selectWidget(AppWidgetHost appWidgetHost, final Activity activity) {
        try {
            int appWidgetId = appWidgetHost.allocateAppWidgetId();
            Intent pickIntent = new Intent(AppWidgetManager.ACTION_APPWIDGET_PICK);
            pickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
            addEmptyData(pickIntent);
            activity.startActivityForResult(pickIntent, R.id.REQUEST_PICK_APPWIDGET);

        } catch (ActivityNotFoundException e) {
            activity.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(activity, activity.getString(R.string.widget_config_no_activity), Toast.LENGTH_SHORT).show();
                }
            });
        }
    }

    /**
     * This avoids a bug in the com.android.settings.AppWidgetPickActivity, which is used
     * to select widgets. This just adds empty extras to the intent, avoiding the bug. See
     * more: http://code.google.com/p/android/issues/detail?id=4272
     */
    private static void addEmptyData(Intent pickIntent) {
        ArrayList customInfo = new ArrayList();
        pickIntent.putParcelableArrayListExtra(AppWidgetManager.EXTRA_CUSTOM_INFO, customInfo);
        ArrayList customExtras = new ArrayList();
        pickIntent.putParcelableArrayListExtra(AppWidgetManager.EXTRA_CUSTOM_EXTRAS, customExtras);
    }

这是崩溃堆栈跟踪:

Answer 1

我似乎设法使用 AppWidgetManager.ACTION_APPWIDGET_BIND Intent 解决了 Android 4.1 及更高版本 (API 16) 上的问题。出于某种原因，Google 声明我们必须将 BIND_APPWIDGET 权限添加到 AndroidManifest.xml 才能使其正常工作，但它对我来说仍然有效(在多个设备上测试过) ).我使用 bindAppWidgetIdIfAllowed 方法来检查我是否需要请求绑定(bind)。

我仍然没有弄清楚如何在 Android 4.1 之前绑定(bind)小部件，即使是对 bindAppWidgetId 的反射。这对我来说已经足够好了，但我会接受任何其他答案以及针对 JellyBean 之前的解决方案(Android 低于 4.1)
