Android : "Unexpected Resume Of <packagename> While Already Resumed" Message?

Oct 3, 2010

Several of my Android applications show the following type message in the logcat output:

I/UsageStats( 59): Unexpected resume of com.totsp.test while already resumed in com.totsp.test

In this case I created the default Hello World app by letting the ADT tool generate it, and it still gets this message. I am not doing anything special in onCreate and don't even have any other methods defined.

I realize this is an INFO level message, and it doesn't appear to hurt anything, but I was curious what was going on so I made a test application that keeps track of the onResume invocations. It is indeed re-resuming when this occurs. I'm wondering why this this occurs? While I haven't noticed a problem (other than these annoying log messages), it seems like it could be using more resources than necessary to do all this stuff an extra time.

I have searched and read a similar question here on SO, and the answer there seems dubious to me: http://stackoverflow.com/questions/2606470/unexpected-resume-of-package-name-while-already-resumed-in-package-name-erro. Specifically, no, you don't want to use android:configChanges="orientation" because that is just subverting the orientation tear down/resume, rather than fixing it. Even the documentation notes "this attribute should be avoided and used only as a last-resort" (http://developer.android.com/intl/de/guide/topics/manifest/activity-element.html#config).

Also I have seen thread in the Android dev group where Mr. Murphy says the "unexpected resume" is "benign": http://groups.google.com/group/android-developers/browse_thread/thread/567410dbfcc163c2.

I'll dig into the source when I get a chance, but I figured I would first just ask the all-knowing hivemind and see if someone already knows: why does this occur, and is it truly benign?

Android :: Unexpected Resume Of Package Name Error In Android

Apr 9, 2010

If changing the orientation of my phone or the emulator I get the following output in LogCat:

04-09 11:55:26.290: INFO/WindowManager(52): Setting rotation to 1, animFlags=0
04-09 11:55:26.300: INFO/ActivityManager(52): Config changed: { scale=1.0 imsi=310/260 loc=en_US touch=3 keys=2/1/1 nav=3/1 orien=2 layout=18}
04-09 11:55:26.460: INFO/UsageStats(52): Unexpected resume of client while already resumed in client
04-09 11:55:26.579: INFO/SearchPosition(807): Activity is paused
04-09 11:55:26.689: INFO/SearchPosition(807): Activity is resuming

SearchPosition is the activity that is displayed. Activity is paused is written in the onPause Method and Activity is resuming in the onResume method of the activity. I googled a little bit for the error message but I don't fully understand the meaning of it. I think it could mean that the old Activity is not properly destroyed after changing the screen orientation. Is this correct? If yes what causes the error? If this is not correct? What is the meaning of this output?

General :: Unexpected Status Message (Automatic Backup)

Dec 7, 2012

I got a surprise status notification today about completed automated backup. I see this message for he first time. Where it came from, as there was no activity attached to the notification.

I do my own backups and have the standard sync and backups disabled, and I have not installed anything particularly weird or non-market since the last time I reflashed the device. To the best of my knowledge nothing but my own backup does backups.

Which app may be responsible for it? I am quite uneasy having apps that backup who knows what who knows where.

Pic of the said notification attached: [URL] ......

The device is a rooted Nexus 7 with stock JB 4.2

Android :: Way To Detect Why Activity Was Resumed In Phone

Aug 24, 2010

I'm developing an Activity that does some of its own state management. I'm trying to differentiate the following onResume cases:

New launch
task switch (home button long-click)
resume after other activity in the same application
wake-up after sleep
orientation change

Is there something in the Activity's intent, or elsewhere, that can help me differentiate these?

For the curious and some context... I'd like to preserve my internal history stack on 4 & 5. On cases 2 & 3, I would preserve the same current page, but erase the history (allow the normal back button functionality to take over at that point). Case 1 would initialize to the activity's internal start page (and can be detected easily enough with some help from ocCreate).

Android :: Previous Set Instance Variables Null When Activity Resumed

Apr 20, 2010

I am using an Application object to store app-wide instance data--data that I need to remain in existence for the entire lifetime of the app, so the Application class seems like the proper place to put it. I have just finished reading this thread http://groups.google.com/group/android-developers/browse_thread/threa... that goes into pretty good detail and receives confirmation from Googler hackbod as to how the Application class performs--and from that info it seems this strange behavior I am receiving should not be happening...

Basically, every once in a while when I resume my app in any of its Activities (it is still running in memory so onCreate is not called) I get NullPointerExceptions because instance variables in my Application class are returning null when I request them from my Activity (via a getter method in my custom Application class). It seems as if sometimes Android saves the states of my Activities but deletes all my instance variable data... This can't be an Android problem--there must be something wrong with my code.

Has anyone else ever ran into an issue of this kind? Any ideas as to what may be causing this? I'm not going to post my code here as that won't help anyone, but hopefully someone can point me in some helpful directions.

Android :: Didn't Expect PACKAGE To Be Resumed Error In Andorid LogCat

Feb 1, 2010

I have an Android app modeled after the LunarLander example by Google.

I am debugging it on a real device, (Motorola Droid) with Android 2.0.

When the orientation changes, the program crashes on a null pointer Exception.

Logcat from just before crash:

CODE:.............

The first line that worries me is "Something wrong here" at 24:38.620. I have no idea what it means, But I think its due to me not reacting properly to the screen change.

Next I get a debug message that I printed myself from within my own method surfaceChanged() about the new surface dimensions.

Then I print out debug message about whether flies was null. flies is the field that eventually causes the NullPointerException. Its created once, and never written to again for the rest of the program. I know that it was not null before the crash, because it was read several times.

Does anyone have a clue how my private member variable came to be null just by these clues?

I would include code but there is a lot of it and I don't know what would be relevant.

Android :: Activity - Sometimes - Throws Wrong State Class Exception When Being Resumed After Kill

Nov 24, 2009

I'm testing how my app behaves when killed by the OS due to low memory conditions. I always have three activities on the stack, like: A B C (then C launches maps or some other heavy process)

when my app is killed, and I return to it, C starts itself up again ok. When I hit the back button to go to B, I [sometimes] get an exception thrown which I can't trace. Output is below. I don't know where to go from here. I've only seen one other post mentioning this exception, but it was related to a reproducable error when rotating the device. This only happens sometimes.

Detect That Service Was Stopped / Resumed By Screen Lock?

Mar 12, 2013

I'm coding a service which does a its job once in every 10 minutes. Works fine. However, when a screen lock gets activated, the service is stopped (which is normal I've found out and I'm find with that). But when the screeen is unlocked again, the 10-minute interval could be already over and I want the service to do the job immediatelly. But... how can I detect that the service was awaken? I schedule the tasks with handler.postAtTime() method.

Android :: Unexpected End Of Document Exception

Nov 21, 2010

I'm getting a "SAXParseException: Unexpected end of document" error when trying to parse an xml document on android. The document in question is from the google weather api, but it seems to throw the same error regardless of the xml file in question (as long as the xml is valid) so I suspect it's a problem with my approach, rather than the xml. This is being done as a learning exercise, so I've probably (hopefully) overlooked something obvious. I've run the xml through an online validator, and it comes back as being well formed. (Can't tell me if it's valid as I don't have a DTD, but I dont think I need the DTD to parse the xml). This is the code that I'm using to try and parse the file:

private void refreshForecast() URL url;
try { url = new URL( "http://192.168.1.66:8000/google4.xml");
URLConnection connection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream in = httpConnection.getInputStream();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
// falls over here parsing the xml.Document dom = db.parse(in);
} } catch (ManyExceptions e) { ....
} A cutdown version of the xml that produces the error is:

<?xml version="1.0"?>
<xml_api_reply version="1">
<weather>
<forecast_information>
<city>Hamilton</city>
</forecast_information>
</weather>
</xml_api_reply>

The stacktrace is:

In the interest of brevity, I've not included the original xml, but it's just the standard weather xml from googles feed. I've also tried a few completely different xml files, (including the sample from http://www.ibm.com/developerworks/xml/library/x-android/) and they all give the same error. (They also all validate as well formed when I run them through an online xml validator). This makes me think that it's not a problem with the xml, but rather with how I'm trying to feed it into the parser.

Android :: SensorManager.registerListener Gives Unexpected Results

Nov 30, 2009

I'm registering a sensor listener with this line of code.

mSensorManager.registerListener(this,mSensorManager.getDefaultSensor (Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST);

The rate is set to SENSOR_DELAY_FASTEST with the expectation that I would receive events roughly every 20-30ms. It turns out that I receive events only every 200-220ms (just now, my event code simply logcats the system time).

No matter which rate I use, SENSOR_DELAY_NORMAL, SENSOR_DELAY_UI, SENSOR_DELAY_GAME, or SENSOR_DELAY_FASTEST, I get the same result?

Android :: Preferences Not Saved When Resume App

Jan 22, 2009

I'm having this problem with one of my apps where some people are reporting that their preferences are not being saved when they close and resume the app. The preferences theyre talking about happen to be actual Preferences (i.e. the built-in preferences manager for an activity). They say they're not doing anything special, just exiting the app and going back to it. Does anyone know why the prefs wouldn't be saved for only this select few people? I'm at a complete loss.

I am writing a simple android application with a class that extends activity, that plays a video from a url on the web. There is a button on top that on click takes the user to a web page.

What I want to do is when the user is browsing the web page, if he hits the back button, I want him to come back to the main activity and restart the video. Is there a way to do this?

Also, is there a way the video can be resumed from where it left off?

Android :: OpenGL And Pause - Resume

I am learning about OpenGL and managed to write a prototype game using VBO buffers. If I start the application from Eclipse or adb, everything works fine until I press the back or <Home> button. If I restart the application either by a long press on <HOME> and selecting my program or by restarting it from the applications, I sometimes get a black screen and the LogCat shows this error:

I am aware that it is probably a wrong setting in my program's flow, but I am not fluently enough with OpenGL.

Android :: Pause And Resume AsyncTasks?

Mar 19, 2010

I have an AsyncTask that acts as a countdown timer for my game. When it completes the countdown it displays the out of time end screen and it also updates the timer displayed on the screen. Everything works fine, except I need to be able to pause and resume this when the pause button in the game is pressed.

If I cancel it and try to re-execute it, it crashes with an IllegalStateException.
If I cancel it and instantiate a new AsyncTask in its place the old one begins to run again and the new one runs at the same time.

Is there a way to cancel/pause the timer and restart it using AsyncTasks or is there a different way I should be going about doing this?

Android :: Astrid Warning - Prevent Unexpected Erase?

Feb 12, 2010

Got a Samsung Moment a couple of weeks ago. Last night starting using Astrid (Task/ToDo app), which came pre-installed on my phone. When I launched Astrid for the first time, I got a warning message -- something about making sure Sprint Update or Sprint Updater doesn't kill Astrid, or ruin it, or something. Clearly, I didn't understand the message. But I clicked "Okay" anyway, and started using Astrid. But I'm worried that a Sprint Update could erase all my Astrid data -- my To Do's. I'm reluctant to create many Astrid tasks until I know how to prevent them from being unexpectedly erased. My questions: Can anyone explain the situation to me? (e.g., I have no idea who/when/how/where/what Sprint updates). Can anyone explain what I need to do to prevent the catastrophe about which Astrid was warning me?

Android :: How To Debug Unexpected Exceptions (source Not Found)

Feb 9, 2010

I am pretty new to Android, the thing that bugs me the most about the IDE is that I am not able to get any information about an unexpected exception when it gets thrown, I can put a try catch block around identified code that generates it, but in many cases it takes time to find the line of code that generates the exception. is there any other way I can get the exception information? in JDT when an unexpected exception is thrown the call stack displays the exception class name. but in ADT this doesn't work.

Android :: Launching Correct Activity On Resume

Jan 22, 2010

I'm currently working with a two-activity application. The first activity allows the user to choose options for their upload, and the second activity displays a ListView of their results once processed.I have code in place that performs the uploads/downloads in the background, regardless of whether the application is currently in focus or not (thanks to Matthias Kaeppler's Droid-Fu).I would like to have my application Resume into my second (results) activity when a user clicks on the icon from the top-level launcher, regardless of how long they have been away from the app. I thought that the 'alwaysRetainTaskState' flag in the Manifest would do it, but I've not had success with that. Can anyone tell me how I need to set up my Manifest to get this functionality?

Android :: How To Make Notification Intent Resume Rather Than Making New One?

Jul 22, 2010

What I have here is a simple webview activity that when loaded it auto displays an ongoing notification. The idea is that people can navigate away from this activity and quickly access it again from any screen they want by pulling down the drop down menu and selecting it. Then when they want they can just close the notification by hitting the menu button and hitting exit and then the notification clears. This all works fine. However, when the notification is pressed it starts a new instance of the activity. What would I have to change to make it see if the activity has not already been destroyed and I can just call that instance back(resume it) and therefore not needing to load it again and won't need to add another activity to my stack.

Android :: RelativeLayout Fill_parent Unexpected Behavior In A ListView With Varying Row Heights

Apr 29, 2010

I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution.

To start, here is my row item layout:

CODE:..........

The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height.

Here is a portion of the getView() method:

CODE:.........

The rest of the method simply sets the appropriate text and images for the row.

Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context);

Am I missing something essential? Or does fill_parent just not work with dynamic heights?

Android : Child Activity Exit By Unexpected Exception - OnActivityResult - Is Not Called

Jun 23, 2010

I have faced with issue about startActivityForResult() and onActivityResult(). If child activity started by the startActivityForResult() exit by unexpected exception the onActivityResult() is not called and I have no any ideas how can I handle this to get application working in a fail-safe manner ?

When my code runs child activity with startActivityForResult() it awaits until onActivityResult() will be invoked to get working further, but onActivityResult() is not calling and my code is "hang- up" (logically).

So the question is how can I handle all possible ways the child activity is finished (normally and by unexpected exception) to get fail-safe code ?

I have check the documentation for this issue but have found nothing relating issue.

Android :: OnPause() - Resume To An Activity Which Has A Bundle Passed To It When Created

Mar 11, 2010

I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A. The documentation says that OnSaveInstance() is called only when the activity is killed, so how do i use OnPause which does not have the Bundle to resume the activity B.
