Question

我正在开发一个Android主页小部件。当我通过单击按钮启动呼叫意图时（即在我通过单击小部件按钮开始的活动中），通话结束后，小部件的按钮不起作用。

当我点击按钮时，按钮的背景会发生变化，因此小部件不会崩溃，它可以工作，但不会加载我认为的意图。并且没有关于此问题的日志记录。

我开始打这样的电话：

Intent callIntent=new Intent();
        callIntent.setAction(Intent.ACTION_CALL);

        callIntent.setData(Uri.parse("tel:"+phone));
        startActivity(callIntent);

然后完成活动。如果我没有再次完成活动它可以工作，但我需要完成活动。

编辑：

以下问题随机发生，电话有时屏幕变黑。当我按下主页按钮时它打开并且小部件按钮工作但是在4-5秒之后我按下动作，但有时屏幕不会变黑并且小部件按钮不起作用。

编辑：

LogCat填充了除最后一个之外的版本错误。但它已得到控制。我用这个控制版本：如果（android.os.Build.VERSION.SDK_INT＆GT; = 11）但它仍记录这些日志。但应用程序运行正常。

我通过将方法移动到另一个类来清除所有版本的错误。但仍然相同，这次有更多的GC错误

以下为我工作

 Uri uri = Uri.fromParts("tel", phoneNumber, null);
 Intent callIntent = new Intent(Intent.ACTION_CALL, uri);
 callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 context.startActivity(callIntent);

电话呼叫后，小工具按钮无法正常工作
