I have registered a Receiver component for ON_BOOT_COMPLETED broadcast, in my application. The receiver does just prints a line in its onReceive() callback. However, when I boot the emulator(by executing Run as->Android application command from Eclipse) and unlock the screen on start up, I get an ANR dialog displayed in my Application. Following are the exceptions logged:

I have connected my Android application to a Windows desktop machine via Bluetooth. The application interacts with the machine. At the end of the interaction the application on the desktop closes the socket that was opened between the Android and the desktop application. Right when socket.close() is called on the Windows machine my Android app pops open a dialog saying that the application has stopped unexpectedly and then it quits. I have a breakpoint on the line in the ConnectedThread (like in the BluetoothChat sample) where I read the InputStream on the Android and that is not hit. I also have a breakpoint in the catch statement for the try surrounding the place where I read the InputStream. That one also does not get hit. So I have no idea how I can catch this error. Is this a bug?

I used the solution (landscape for all), but now, only in the real device, when i start the app and i have the device in portrait mode it crashes (need to force close) and only after reboot the phone its possible to connect to camera, even in the camera app.

How easy is it to make an application that's just a wrapper around the browser? Can the Android OS boot directly into that application so that only a certain application launches after boot. I'm building a client some custom software and I'd prefer to use one of those Archos 5 MIDs than a Linux netbook.
View 2 Replies View RelatedSo I started with this little write-up. I wanted to try to make an application that will take pictures while running in the background. To start though I wanted an application that once opened would simply take a picture every X seconds. After recreating the classes and methods show in the walk through below I ran into a few problems.
http://itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf
For starters its seems that the onCreate function sets up all the objects for the application, but if you try to take a picture through any other method than onClick (IE directly calling it) the application actually hasn't setup the canvas or the preview yet.
My first question:
Is there any conditional method that you can setup that will wait till all the "onCreate" objects are created and their associated methods are called and finished? How do I wait for the application to finish putting together my surface and starting the cameras preview before automatically starting to take pictures?
My second question:
I am required to have a preview available to take pictures. Is there anyway to push this application to the back (IE running in the background) while still taking pictures? Is drawing to a canvas a requirement? (From what I can tell AFAIK, you are required to have a surfaceholder to start preview, when you put up another screen or application that pauses the current application and closes the surface/canvas you were presenting that preview on). If my understanding is correct on all of this the best I will be able to do is make a 1x1 pixel canvas that will still take up the screen due to the application being in the foreground.
My Third question:
Is there any way around this? Can you still utilize the camera in some fashion without requiring the preview be drawn?
My app is using the camera on the phone. For phones w/ 2.0+ I have been able to activate the Flash. When I test on a phone with 1.5 OS on it the app crashes. I get: java.lang.reflect.InvocationTargetException and the Cause is java.lang.VerifyError: fishers.Nav.TakePicture$1
I assume because you have to access the flash differently in apps below 2.0? Can anyone give me some advice or links to examples showing how I could make it work over the whole range of Operating System version or is that just not at all do-able?
I have a small mp3 (326KB) in my res/raw folder. In my code, I have mPlayer = MediaPlayer.create(FakeCallScreen.this, R.raw.sample); Player.prepare(); mPlayer.start(); The application just crashes when it tries to start the activity, I cannot figure out why.

Shown are a few lines of code. If I play a single sound, it runs fine. Adding a second sound causes it to crash.

View 1 Replies View RelatedI'm nearly ready to publish my OpenGL game. I've been browsing this newsgroup and I've seen quite a few posts regarding crashes, blank screens, etc when running an OpenGL application on the Droid. I have three questions:
1) What are some common pitfalls that occur when trying to support the Droid/Nexus One? So far, I've tested my game on the Android 2.0 emulator (both WVGA & FWVGA) and everything works fine but I'm still paranoid.
2) I've placed my textures (png) in the assets folder. Will these images be pre-scaled automatically? I've read about specifying density independent images for resources but do the same rules apply for images stored in the assets folder? I'm afraid that pre-scaling will cause my textures to become non-power of 2.
3) What additional strategies have developers been taking to ensure their application works on the newer devices when they only have access to G1/G2 hardware?

First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

I either have to pop the battery or plug into power to force a reboot. Im not sure how to figure out what application might be causing the problem or if maybe it is a hardware issue. Does anyone have any idea what might be causing this, or know what I might do to start troubleshooting?
View 2 Replies View RelatedI'm trying to understand remote services at the moment and everything works fine, i can start the service and know how to communicate with it through the AIDL-interface. My problem is that the service seems to still run in the same process like the activity it was started from, because the activity crashes too, if there is an error thrown in the Service.
I set the service process to remote ( android:process=":remote" ) so what am i doing wrong? Or what do i have to do to unbind the service-process completely from the activity-process?

How to fix landscape mode when boot on device?
I had change manifest.xml ->
CODE:...........
But that only change sensorDemo screen. That doesn't I want. I want to set landscape mode when boot on device and show main screen. what methods does I try it?
If I take the SIM out, the device will boot and give me access to contents, (obviously, phone is off).BUT if SIM is in, I cannot get past the pin input screen, and this is exactly what I want to do.
I want to be able to give the device to my son to i.e. read a pdf, but I do not want him to be making / answering calls on my SIM.
Sure, I can take it out, but do not want to if I do not have to. (I might lose it too!)
In other words, if no pin is entered, one must be able to use all but the phone on the device.
After all, the lock is for the SIM, not the device!
Very often I find myself needing to reset or get around someone's Windows Password, the easiest way of course is with one of many available linux boot cd's that'll edit the windows system hive. However most of the time I'm not carrying this around, I have a USB stick that can be used but I noticed earlier that while my Nexus One was plugged into the USB port on boot it is detected by my bios.
So the question is - Can the android USB interface act as a boot device? If so I assume it'd need a different partition since it's already got an OS?
(Also while I have your attention: 1) Did they ever fix the +1 area code problems with contacts?, 2) Why don't half my contacts show up in Send MMS dialogue (and others)?, 3) How do I tell if I have an SLCD or AMOLED screen cos sometimes the screen looks really crappy (dithering or off colour banding) AND FINALLY 4) can you set notification sounds differently depending on time of day (ie; I don't want a new gmail alert to wake me up at 2am.
