I am trying to write a sample program to record the video (say camcorder application). When i run my program using the emulator (I have android-sdk- windows-1.5_r3) I see java.io.IOException: prepare failed. error in logcat output.
Further I can see that I have came across this error when i call MediaRecorder.prepare() from CamcorderActivity.surfaceCreated() But I am surprised to see that activity got launched and I am seeing the camera preview! Again the preview is seen only in half of the screen! Its weird!!!
Further when i do recorder.start() to record the video I get java.lang.IllegalStateException. Yes this is obvious since the prepare () has failed. But the question is why prepare() has failed ?
Here is my code ... package com.example;

I have already posted on their developer group but based on everything I've seen I don't expect a reply. I have a strange problem. When I added and adview to my app it imported a bunch of comments that all start with /** Eclipse is acting like it is not a comment. Although it isn't erroring out it has now marked anything starting with R.id as not existing. Is this something I can remedy in eclipse or is it time to chuck my dreams of being mega rich off of all the admob revenue I will be receiving? Writing code is one of few things that teaches me I don't know everything. Join the Closed Beta of Call Girl Manager http://www.fuligin.com/forums

View 2 Replies View RelatedA customer just notified me that she's experiencing the infamous "app not responding / wait, force close" message during a specific operation. By just waiting enough, the app resumes ok. Now, that specific operation is indeed long and in fact it has been programmed in a background thread, with a progress dialog signaling the wait. I can't reproduce the problem on my development phone - I suppose because it's perhaps faster than the phone of the user. But I can't reproduce the problem either with the emulator, which I suppose is slow enough. Generally speaking, I think I could be able to solve this specific problem with the customer giving me the proper feedback. It's the general issue that hassles me. This part of the application is very good covered by tests at different levels, including automated black-box tests with Robotium that drive the UI as the user would do, and even in "stress mode" (repeating the test multiple times). So I supposed to be very safe in that area and I'm disappointed to discover that it was a false sense of safety. What am I possibly missing? Also, is it possible / does make sense to "slow down" a phone during tests? I was thinking of a service running in background just consuming some CPU cycles to make the phone less responsive.

View 3 Replies View RelatedI have a strange issue. I am using KSOAP2 to create a soap request to a .net webservice. I do this in a few other places and everything works fine. The webservice basically queries a data base and takes the values from the data reader and creates a string. This string is then returned. When I run the webservice on my local machine(Without using android) it works fine. When I run it from the webserver (still not android) it works fine. When I call it from my phone however the line: String hazards = (String)envelope.getResponse().toString () ; //Get response from .net Web service Simply is filled with anyType{}. Now if I go to the webservice and I manually type in the contents from the database to represent what the string concatenation should be it works perfectly. The line: String hazards = (String)envelope.getResponse().toString(); //Get response from .net Web service Now returns the string value i need. Does anyone have any idea why this is happening or know a better place to ask this question?
View 4 Replies View RelatedI'm trying to get my head around how the vram is used in opengl, specifically when and how to clean it up. The Story So Far. I have a GLSurfaceView into which I set a Renderer implementation (called OpenGLRenderThread). This view is created (manually, by calling "new") in the main Activity of the app. When the onSurfaceCreated method of the OpenGLRenderThread is called, I load a bunch of textures in a fairly standard way: the app runs fine, however when I try to clean up these textures at the end of the "level" (the app is a game. I do the following: On the emulator it works fine, but on the device (HTC Desire, 2.1) I get a GL Error 5572216 I have no idea what this error code is as I can't seem to find any reference to it. I understand that the VRAM references are bound to the thread that created them. Hence they can only be destroyed by the same thread. In my case, this thread is the OpenGLRenderThread (Renderer) during the onSurfaceCreated call.Unfortunately the Renderer interface does not expose an "onSurfaceLost" method, so I created my own. When the Level is complete, my main activity queues a request on the OpenGLRenderThread using the following call to the GLSurfaceView: According to javadoc for queueEvent: "Queue a runnable to be run on the GL rendering thread" Ok fine, so this should mean that the OpenGLRenderThread is performing the call to onSurfaceLost. This method is the one that then calls glDeleteTextures, and produces the error. what am I doing wrong here? I am not destroying the OpenGLRenderThread or the GLSurfaceView at any point (other than game exit) so I'm worried that if I don't explicitly delete the textures my vram will eventually fill up, or worse get into a corrupt state. The only other thing that may be relevant is the use of a ViewFlipper. Because I want to load each level asynchronously I am using a ViewFlipper in the main activity to flip to a loading screen while all the level resources are rebuilt. Hence when the call to glDeleteTextures is made, the GLSurfaceView is not actually visible not sure if this is meaningful or not.

The wording may not be exact, but that's pretty close. Then it would dump me back to the home screen. I ended up rebooting and now it works fine.

View 2 Replies View RelatedGot IOException in android?
CODE:..............
why i got it?
I'm trying to parse an XML file from res/raw or assets/ using the javax SAX parser. When the file is too large (~ 1MB), the parse(...) method throws an IOException without further information, such as message or inner exception. When I reduce file size to e. g. 600 kB, it's working again.
View 2 Replies View RelatedI have just started with Android development, and facing one issue in the android application.

I am trying to get the geo codes for an address.
I am using: Geocoder geocoder = new Geocoder(GeoNoteEditor.this, Locale .getDefault()); List<Address> addressList = null; addressList = geocoder.getFromLocationName(addressString, 1);
The problem is that I am getting an IOException sometimes when I call getFromLocationName for the same addressString. This does not happen all the time. When I get the IOException, if I repeat the getFromLocation call, sometimes it works sometimes I get the IOException again.
How do I prevent the IOException from happening?
I'm running into a strange problem while reading from an InputStream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general.
The only thing that is Android specific is this call:
CODE:........
This returns an InputStream for a file from the Android assets. Anyways, here's where I run into the issue:
CODE:........
When the read() executes it throws an IOException. The weird thing is that if I do two sequential single byte reads (or any number of single byte reads), there is no exception. Ie, this works:
CODE:........
Any idea why two sequential single byte reads work but one call to read both at once throws an exception? The InputStream seems fine... is.available() returns over a million bytes (as it should).
Stack trace shows these lines just before the InputStream.read():
CODE:........
Changing the buffer size to a single byte still throws the error. It looks like the exception is only raised when reading into a byte array.

What is the preferred way of reusing a MediaPlayer when using resources? My try looks a bit ... too complicated... so maybe I should be happy to see that it didn't work. (I run the Android 1.5 SDK and emulator.)
According to this thread my problem may be a permission problem. http://groups.google.se/group/android-developers/browse_thread/thread...
I get the same error. But in my case it only occurs when I use FileDescriptor!?! The use case differs however, because I use a resource stored in the bundle. I have s0.mp3 safely stored in the project /res/raw and it successfully plays when I use SoundPool or MediaPlayer.create. And the log print tells me I referenced the correct file and stay safely in my package.
I'm sure my way of getting the fd out from a package resource is the problem, I didn't find any other way... But why didn't setDataSource throw the exception instead of a printout? And why on earth is the same resource happily played one way but not the other? Seems like a design flaw rather than a security raise. Should I look in the MediaPlayer.create code to see how they get around the problem or can you help me understand how it works?

Every time I try to run an Android project from Eclipse with the Android plugin (Run -> Run), the emulator starts up just fine, but the upload fails, and the Console puts out this error message:
[2010-06-17 08:17:55 - HelloAndroid] Failed to upload HelloAndroid.apk on device 'emulator-5554'
[2010-06-17 08:17:55 - HelloAndroid] java.io.IOException: Unable to upload file: Local file doesn't exist.
[2010-06-17 08:17:55 - HelloAndroid] Launch canceled!
It seems as though the apk compilation is failing, but there are no other errors in the Console at all except for a lone warning about the project not specifying an API Level requirement:
[2010-06-17 08:17:55 - HelloAndroid] WARNING: Application does not specify an API level requirement!
[2010-06-17 08:17:55 - HelloAndroid] Device API version is 8 (Android 2.2)
My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:
Unable to parse response from server
Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.
I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.
I'm having problems during the "read" call of the InputStream. The call gives me a "IOException: Software Caused Abort" exception. I'm able to get the BluetoothSocket and also the able to "connect" to the device. My app. is in the client mode and sends in a "x" byte "command" to the device which is then supposed to send me a "response". The expected "response" is also of "x" bytes. This is where the error arises.. While reading the "response" i'm getting the above mentioned error.
View 5 Replies View RelatedI'm using the following to draw rounded-corner rectangles in my Android application and it seems to be working alright but with one minor problem:

The strange thing is that the two ends of the rectangle aren't rounded over the same. The left-size quarter circles are noticeably smaller than the ones on the right.
Anybody experienced anything similar? It's weird enough that I might change my mind about the round corners if I can't do anything about it.... And if I knew how to do a screen capture from my Android, I would.
The rectangles in question are 78 pixels wide and 48 tall, if that helps (and since ykatchou may be onto something).
