I found that the old bug reported in http://code.google.com/p/android/issues/detail?id=1578 where only a power cycle brings back the camera still persists with the official Cupcake firmware on my ADP. When it happens - and I've encountered it several times in a few days now - no camera application can access the camera. A power cycle is needed to recover from this locked camera state.

Only started happening since the most recent update. before that it was good. Updated both phone and computer side software and now it locks up my 64bit windows ultimate machine every 2nd time I log into PhoneMyPc. I can log in once fine, the second time will cause the computer to freeze.

View 2 Replies View RelatedSo I was out on my motorcycle and had about 60% battery left on my Vibrant.Figuring I wasn't going to need the phone for a few hours I powered the phone off, calling myself saving battery.When I turned the phone back on I was totally surprised that the battery was down to 38% immediately following powering up.This happens every time I power the phone down-I lose about 20% consistently.It also happens when google maps shits itself and either freezes the phone (necessitating a battery pull reset) or causes a spontaneous reboot.Is this normal? I've had my phone for a bit over two weeks (so out of my remorse period) and my besides this my battery works and lasts rather well, considering how much this phone has going on.

I've noticed that when I do a soft reset (power cycle phone off and on) that the start up screen has what looks like dead pixels. When the phone actually boots up to the HTC screen with Android waving the "dead" pixels disappear. They only appear on start-up and go away at the HTC screen with Android. I noticed about 5 "dead" spots. Is this normal?

View 10 Replies View RelatedI'm writing an app that needs one or more applications/services that are distributed with their own seperate apk file. I'm writing a user-app that allows the user to upload pics using a service. The service can be used by multiple user-apps, not just mine. I'd like to have the service being installed in its own apk, instead of bundling it with each user-app. Has anyone had experience with this scenario? What is the best scenario i should implement so that the user downloads the service that the user-app needs? Can be this be done automatically (that would be best)? If not, in your opinion, what would be the most user-friendly way for doing so?
View 4 Replies View RelatedI am writing my first Android database backend and I'm struggling to unit test the creation of my database. Currently the problem I am encountering is obtaining a valid Context object to pass to my implementation of SQLiteOpenHelper.Is there a way to get a Context object in a class extending TestCase? The solution I have thought of is to instantiate an Activity in the setup method of my TestCase and then assigning the Context of that Activity to a field variable which my test methods can access...but it seems like there should be an easier way.
View 3 Replies View RelatedI am working on an android app that needs to act on a few data files totaling around 30MB. I put together a test and the emulator failed with OutOfDiskSpace. Debugging on a device failed with even a smaller data size. After reading through the google groups, it appears that the application size limit isn't stated anywhere and nobody from google has been forthcoming with specifics about this. Given that there are iPhone apps that are over 100MB in size, putting such a small limit on Android apps seems weird, except just for the fact that you have a relatively small amount of total available app storage space (< 100MB).What techniques do you use to deal with this limit? If you have an app that needs more than 10MB, do you put it on a web server and deal with downloading it the first time? If so, how do you handle access control so that only your app can get the data?

To access the wireless at my university the network is 'open' but you have to sign in (personal user name and pass) via a login webpage prior to actually being connected to the wifi. It's kind of annoying to have to do this every time instead of the phone just connecting to the network.So two options that I am wondering would be possible:
1. best case, somehow it can automatically sign into the network once it is detected (e.g. run a script which enters login/pass to webpage)
2. at least have the user name and pass remembered (i cant figure out how to have it remember logins).
I should note, I have disabled cell tower data transfer (reason I bought the nexus one so I didn't have to pay $30 a month when wifi is everywhere!). So accessing wifi is the only way I get data connection; hence the importance of directly/automatically connecting
I have an observation concerning how Android handles scheduled events and would like any suggestions, comments, or feedback on how other developers have handled this behavior in Android. I have noticed that there does not appear to be anyway to schedule an event to happen at "regularly" scheduled times. By regularly scheduled times I mean a long-lived service/schedule that must run every "n" minutes. For instance, an application that must check the status of a web service at user specified intervals (like every 10 minutes). I have tried a writing a service to run in the background using Context.start Service, Android stops that service after a few minutes. And, there are many senior Android developers that recommend using the "alarm that starts a service" method for this type of application. My testing on Context.Start Service would tend to agree. My best results have been using an alarm to start a service, although the results are still less than stellar. I have done weeks of testing trying to get Android to run a service every 10 minutes (or even close to 10 minutes) using the "Alarm that starts a service" method. The best I can get in a 24 our period for an alarm scheduled every 10 miutes is about 75% (110 out of 144 repeating alarms). I have tried varying this interval from 1 minute to 30 minutes with the same result. I have tested on a non-rooted T-Mobile both 1.0 and 1.1 firmware. I have tested on an ADP using both 1.0 and 1.1 firmware. I have tried using "PARTIAL_WAKE_LOCK" and "FULL_WAKE_LOCK" feature of the PowerManager. Nothing seems to work. Android just will not run an event consistently. I had high hopes for the repeating alarm that starts a service, but it seems Android always skips many of the scheduled alarms. I am beginning to think that "Reguarly" scheduled events is not even possible in Android. I'm looking for any comments and suggestions from developers and Android engineers.

View 6 Replies View RelatedI tried searching for this but couldn't find a thread that discussed it. My power button appears as though its been jammed. I dropped my phone on its corner where the power button is but I don't think thats what the problem is. Anyhow, recently my power button responds but I have to really press it hard and it as though the button is jammed cause it doesn't depress as far.
My question is that is there a way to designate the camera button to become the power button? I know on some phones you can make different buttons do different things and I was curious if this was possible on the Droid.
The main activity is running, then there is a interrupt. What was happended, onPause(), onStop() or other change of life cycle? 1. pressed the volume_down key and ringer volume toast occured, the life of main activity will not change? why? 2. short press the power key and the OS sleep,how about the activity ? 3. long press the power key and the phone options appear, how? 4. long press the home key and the tast list appear, how? 5. notifications curtain appear, how? 6. press the back key,how?

View 2 Replies View RelatedWhen starting a new Activity, I want to pass a complex object and do so by using this approach:
MyActivity.COMPLEX_OBJ = myComplexObj; // which is definitely NOT NULL! Intent intent = new Intent(); intent.setClass(this, MyActivity.class); startActivity(intent);
and then in MyActivity:
@Override public void onCreate(Bundle bundle) { if (COMPLEX_OBJ == null) { // report to Flurry ... } ...
}
I am having a really hard time grokking the Activity life cycle concept. The main issue is with onStop() and onDestory() not being guaranteed to be called before the process is killed. I though I had it figured out when I saw that the system calls onSaveInstanceState() when it's shutting down the activity to claim some memory. Thing is that the docs says onSaveInstanceState() will be called before onPause() but how does the system know at this point whether the activity will be killed by the system or the user?
Here is a use case:
1) My activity starts up and is running. 2) At some point I want to show a web page so I use an Intent to start an activity. 3) The web browser covers my app/activity so I would expect onPause() to be called followed by onStop(). At this point it's my understanding that all bets are off and I can be killed at any point without be called. 4) Since the system has enough memory onSaveInstance() doesn't get called. 5) The user presses home and decides to open some app which requires a lot of memory. 6) System wants more memory and decides to kill my app but I am already stopped (onPause() has been called).
The core of this Widget is an AppWidgetProvider which registers a ContentObserver to the CallLog content URI. This means that my widget is updated every time a call (incoming, outgoing, missed) is recorded. This works fine for a while, until *something happens* and my ContentObserver stops getting called (no error message seen in trace). I would rather that this ContentObserver persisted until the user removes the Widget.
I am guessing that my JVM has been destroyed (due to low memory?), ContentObserver garbage collected and/or ContentObserver unregistered (or just pointing to nothing), but I don't know how to debug this without restarting my code (and thereby re-registering). I can hide this bug by periodically re-registering my Content provider, but I would rather understand the cause and have a more optimal solution..............
When I start my application I prompt the user for the password and use it to instantiate my data adapter object that I will need throughout the application. So I store it in Application object. My activity A prompts user for pwd, instantiates data adapter, sticks it to Application object and later starts activity B which in turn starts the built int gallery activity. When fooling around with gallery and capturing pictures for some time coming back to activity B I discover that Application.myDataAdapter is null. I found out that during me playing with camera the Application.onTerminate() method was called. So it seems like Android killed my process and when B was supposed to become visible it started a process again jumping directly to activity B bypassing A? Is that how it works? Should I then never assume that Application.myField will survive? and init it not only when A is started but whenever I discover it is null?

So I have 2 reports now of my app causing a crash/reboot cycle the user can't always break from. I cannot reproduce this on my phone, and I am wondering what might be causing something like this? Would running out of memory or something cause this? Because I can't reproduce it, I can't look at the logs or anything.
Has anyone experiences anything similar? For reference, my app runs a foreground service which utilizes the AlarmManager. It starts automatically on boot_completed (which is probably why the cycle happens). One of the users who reported this, said it only happened when they plugged their phone into a PC.
