问题描述
我正在做 Android Wear 项目.通过 contentAction 向用户显示通知，因此用户可以点击它.点击它后，SomeActivity 会与 DelayedConfirmationView 一起显示，让用户有时间取消即将到来的 API 请求.当 DelayedConfirmationView 完成 API 调用时进行.API调用成功后显示ConfirmationActivity.当 ConfirmationActivity 返回时，我们 finish() SomeActivity 并取消通知.
I am doing Android Wear project. Notification is displayed to user with contentAction, so user can tap it. After taping it SomeActivity is displayed with DelayedConfirmationView giving user time to cancel upcoming API request. When DelayedConfirmationView finish API call is made. After API call succeeds ConfirmationActivity is shown. When ConfirmationActivity returns we finish() SomeActivity and cancel the notification.
我面临的问题是 SomeActivity 启动后它莫名其妙地停止了.与崩溃一起的日志如下所示:
The problem I face is that after SomeActivity starts it is mysteriously stopped without a reason. The log together with the crash looks like follows:

创建通知剪断:
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;
}
某些活动:
public class SomeActivity implements
DelayedConfirmationView.DelayedConfirmationListener
{
private static final int SOME_NOTIFICATION_REQUEST_CODE = 99;
private DelayedConfirmationView delayedConfirmationView;
private TextView description;
private ProgressView progressView;
private TextView saveLabel;
protected GoogleApiClient googleApiClient;
@Override
public void onCreate(Bundle bundle)
{
super.onCreate(bundle);
setContentView(R.layout.activity_some);
this.description = (TextView) findViewById(R.id.activity_some_description);
this.delayedConfirmationView = (DelayedConfirmationView) findViewById(R.id.activity_some_delayed_confirmation);
this.delayedConfirmationView.setTotalTimeMs(Constants.DELAYED_CONFIRMATION_ANIMATION_TIME_IN_SEC * Constants.MILIS_PER_SECOND);
this.progressView = (ProgressView)findViewById(R.id.activity_some_progress_view);
this.someLabel = (TextView)findViewById(R.id.activity_some_label);
CardScrollView cardScrollView = (CardScrollView) findViewById(R.id.activity_some_card_scroll_view);
cardScrollView.setCardGravity(Gravity.BOTTOM);
new GetDataFromDBAsyncTask().execute();
this.googleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Wearable.API)
.build();
}
@Override
protected void onStart()
{
super.onStart();
this.googleApiClient.connect();
}
@Override
protected void onResume()
{
super.onResume();
Handler handler = new Handler();
handler.postDelayed(new Runnable()
{
@Override
public void run()
{
onStartTimer();
}
}, 500);
}
@Override
protected void onPause()
{
super.onPause();
this.delayedConfirmationView.setListener(null);
}
@Override

{
super.onStop();
if (null != this.googleApiClient && this.googleApiClient.isConnected())
{
Wearable.MessageApi.removeListener(this.googleApiClient, this);
this.googleApiClient.disconnect();
}
}
@Override
public void onConnected(Bundle bundle)
{
Log.d(Constants.LOG_TAG, "Google API client connected");
Wearable.MessageApi.addListener(this.googleApiClient, this);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SOME_NOTIFICATION_REQUEST_CODE)
{
WearableNotificationCenter.getInstance(SomeActivity.this).cancelNotification();
finish();
}
}
public void onStartTimer()
{
this.delayedConfirmationView.setListener(this);
this.delayedConfirmationView.start();
}
@Override
public void onTimerSelected(View view)
{
view.setPressed(true);
// Prevent onTimerFinished from being heard.
this.delayedConfirmationView.setListener(null);
finish();
}
@Override
public void onTimerFinished(View v)
{
this.delayedConfirmationView.setEnabled(false);
this.delayedConfirmationView.setVisibility(View.INVISIBLE);
this.progressView.setVisibility(View.VISIBLE);
this.saveLabel.setText(R.string.saving);
sendApiRequest();
}
private void showSaveConfirmation()
{
Intent intent = new Intent(this, ConfirmationActivity.class);
intent.putExtra(ConfirmationActivity.EXTRA_ANIMATION_TYPE,
ConfirmationActivity.SUCCESS_ANIMATION);
intent.putExtra(ConfirmationActivity.EXTRA_MESSAGE,
getString(R.string.done));
startActivityForResult(intent, SOME_NOTIFICATION_REQUEST_CODE);
}
private void sendApiRequest()
{
some code
}
@Override
public void handleApiResponse(MessageEvent messageEvent)
{
showSaveConfirmation();
}
}
我尝试了很多方法来使其正常工作，但没有任何效果.有任何想法吗?DelayedConfirmationView 会导致这样的错误行为吗?我在网上看到了一些例子，他们甚至在 onCreate 中启动它，所以它不可能.
I was trying many things to make it working but nothing really worked. Any ideas? Can DelayedConfirmationView cause such a misbehaviour? I saw examples in the Net and they start it even in onCreate, so it cannot be it.
最让我烦恼的是在onPause之前调用了onStop.这很奇怪.在 SomeActivity 中，您可以看到在 onStop 中，我断开了与 GoogleApiClient 的连接，但 Activity 仍处于活动状态，因为日志显示它在 Activity 启动 3 秒后尝试调用 API(3 秒需要 DelayedConfirmationView 完成).问题是这个活动没有显示给用户，因为神秘的 onStop 被调用了.
What bothers me most is that there is onStop called before onPause. This is very strange. In the SomeActivity you can see that in onStop I disconnect from the GoogleApiClient but Activity is still alive, because logs shows that it tries to call API 3 seconds after activity was started (3 seconds take DelayedConfirmationView to finish). The problem is that this activity is not displayed to the user since mysterious onStop was called.
推荐答案
看起来最新的操作系统更新解决了这个问题.
Looks like latest OS update solved the issue.
