我的用户报告当他们尝试使用我的应用程序（而不是启动器应用程序）选择窗口小部件时发生崩溃。 我使用的是标准小部件选择器代码，它始终有效且仍可在所有设备上运行，除了LG G2和LG G3 。
我发现了一些类似的问题，但他们都提到Android 2.1遭遇的崩溃是通过空数据解决方法解决的（已在我的代码中实现）。
还使用alternative way来获取小部件，没有官方选择器 - 这有效，但要求应用程序是BIND_APPWIDGET权限的系统应用程序。
任何人都遇到过这个问题，也许找到了解决方法或解决方案？
由于
以下代码：
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);
}

答案 0 :(得分：1)
似乎我设法使用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声明我们必须向BIND_APPWIDGET添加AndroidManifest.xml权限才能使其正常工作，但无论如何它都适用于我（在多个设备上测试）。我使用bindAppWidgetIdIfAllowed方法检查是否需要请求绑定。
我仍然没有弄清楚如何在Android 4.1之前绑定小部件，即使反映到bindAppWidgetId也是如此。这对我来说已经足够了，但我会接受任何其他答案的解决前JellyBean（Android 4.1以下）
