我在做Android Wear項目。通知以contentAction顯示給用戶，因此用戶可以點擊它。錄製後SomeActivity與DelayedConfirmationView一起顯示，給用戶時間以取消即將到來的API請求。當DelayedConfirmationView完成API調用。顯示API調用成功後ConfirmationActivity。當ConfirmationActivity返回我們finish()SomeActivity並取消通知。Android Wear setContentAction開始並很快停止活動導致：執行暫停的活動，但未恢復
我面對的問題是，SomeActivity啓動後，它被神祕地停下來沒有理由。與碰撞在一起日誌看起來像如下：

創建通知剪斷：
private NotificationCompat.Builder createNotification()
{
NotificationCompat.Action someAction = createSomeAction();
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this.context)
.setSmallIcon(R.drawable.logo)
.setLargeIcon(BitmapFactory.decodeResource(
this.context.getResources(), R.drawable.logo))
.setContentTitle(title)
.setContentText(subtitle)
.addAction(saveAction)
NotificationCompat.WearableExtender wearableExtender = new NotificationCompat.WearableExtender()
.setBackground(BitmapFactory.decodeResource(this.context.getResources(), getRandomBackground()))
.setContentAction(0)
.setCustomContentHeight(Utils.dpToPx(100, this.context));
notificationBuilder.extend(wearableExtender);
return notificationBuilder;
}
private NotificationCompat.Action createSaveAction()
{
Intent saveIntent = new Intent(this.context, SomeActivity.class);
PendingIntent savePendingIntent =
PendingIntent.getActivity(this.context, 3, saveIntent, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Action saveAction =
new NotificationCompat.Action.Builder(R.drawable.save,
this.context.getString(R.string.save), savePendingIntent)
.build();
return saveAction;
}
SomeActivity：

我嘗試很多東西，使其工作，但沒有什麼工作。有任何想法嗎？ DelayedConfirmationView是否會造成這種不良行爲？我看到了網絡中的例子，他們甚至在onCreate開始它，所以它不可能。
最讓我困擾的是在onPause之前調用了onStop。這很奇怪。在SomeActivity中，您可以看到在onStop中，我與GoogleApiClient斷開連接，但活動仍然存在，因爲日誌顯示它在活動開始後3秒（3秒以DelayedConfirmationView完成）嘗試調用API。問題是這個活動不會顯示給用戶，因爲調用了神祕的onStop。
