So 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.

I have a G1 Android that's been rooted. My problem is that Market and Gmail crashes on launch. I also cannot get to the Data Synchronization page. It displays the page for a split second and then instantly closes out. Is there a way to reset the apps? I've tried factory reset and upgrading to a newer version of Cyanogen mod without success.

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?
View 1 Replies View RelatedMy Incredible has recently started to crash frequently and it seems to keep getting worse, now at least once or twice per day. It never crashes while I am using it, but I will go to check it later and it is dead. This is getting frustrating because I am missing calls without even knowing the phone is off. 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?
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?

Is there any way to catch crashes in my own android app? Something like a global uncaught exception handler?

View 2 Replies View RelatedI'm having a problem where my app crashes on the Droid and seems to work fine on the G1. We have a G1 dev phone but do not have access to a Droid phone, so the issue is difficult to debug at this stage.
The app loads up the main screen okay, but once the user moves beyond the main screen, the app crashes. Moving beyond main screen initiates the following:
- GPS signal acquired - Accelerometer sensor listener active - Geomagnetic sensor listener active - Camera preview active
I have a suspicion that the issue may be related to the camera preview. With the G1, it didn't seem to matter how I set the camera preview size, so I just made it fit the size of the view.
Camera.Parameters parameters = mCamera.getParameters(); parameters.setPreviewSize(w, h); //where w, h are the width and height.
One possibility is that with the Droid having a larger screen resolution to the G1, it may be setting the preview size to something that is not supported. I plan on addressing this, but I have a few questions that I was hoping someone could shed some light on.
1. If the app attempts to set a preview size that is not supported, will it just be ignored or will the app crash?
2. If the preview size is smaller than the surface that is holding the preview, will the image be stretched to fill the surface?
3. Can anyone think of anything else that may be related specifically to the Droid that could be causing me problems?
I have some WebView widgets inside my Activity. I use loadData() to set the content, and this html contains a link. Some of my WebViews work okay, when I click the link, the web browser is started in a new window, but some make my app crash when I click on a link.

My application is basically a image viewer. It is opened from both camera and as a separate application.
I open the image viewer to view and edit the picture. Each edit operation is implemented using thread. If my application closes due to pressing the home button, the next time I open it with camera. It throws anr.
This doesn't always happen. Only when large edit operations or edit operations on large image files are done.
I get out of memory error, sometimes timeout.
I guess it s because the thread doesn't complete the edit operation when home is clicked. and it s still running on the background. so when i open it s unable to process it.
m I right?
If so what is the way to stop a thread before the completion?
When I pause Pandora for more than a few minutes, the widget absolutely refuses to respond and I have to kill Pandora with a task killer (this is the sole reason I keep the tk around) and then I have to use the icon instead of the widget to restart it.
When it crashes, I have to hit the widget like 7 or 8 times to get it to open up full screen. Then I can hit the 'Like' or 'Dislike' button and they will turn blue for a second but no check appears and the play button does absolutely nothing till I go in and do the kill thing. If I try to just hit the icon before killing it, it opens up full screen does the exact same unresponsive thing.
I have my yahoo account setup in the android email app. Thanks to a previous post got it working beautifully.. when i click an email that has an image attachement and chose the Save function, its then shows the crash/error messege "The application Email (process com.android.email) has stopped unexpectedly.
