Android :: MediaRecorder Error: Java.io.IOException: Prepare Failed
Sep 8, 2009
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;

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?
This is a test code snippet: (from onCreate of a simple Activity)

And the error:

Attempted to update to 2.1 , everything appeared to go ok , but after restarting i saw that firmware was still in 1.6 .
The only effect was that my intended apps etc. were gone.
According to SE PC Companion the phone is up to date.
According to the phone's software update a new version of Android is available ..
Using the SE PC Companion to repair ( ca'nt install since aIready have the latest sw according to SE-PCC )
results in installation error when reaching close to the end of the prepare phase.

Attempting to import my code from 1.0 to 1.5 sdk. just a bit of background info, i originally wrote the code for 1.0 on a windows machine, now i have a mac, eclipse and the latest sdk and would like to import and continue coding.
The import went bumpy and some problems were solved from this post:

After I performed the android properties fix and did a clean rebuild I'm getting an error in R.java.
Eclipse says that "The type R is already defined."
Any thoughts?
is there a way to force regenerate R.java?

I'm calling Debug.startMethodTracing("fnord") and I'm getting a java.lang.RuntimeException: file open failed message. It looks like I'm supposed to have the android.permission.WRITE_EXTERNAL_STORAGE permission set. But how do you set that permission when you're debugging through Eclipse? Aren't permissions normally set at install time (which doesn't happen in a normal way when you're debugging)?

I have received the following error when trying to install packages through the SDK and AVD manager tool: XML verification failed for http://dl-ssl.google.com /android/repository/ repository.xml. Error: The markup declarations contained or pointed to by the document type declaration must be well-formed. I have downloaded the latest versions of the Android SDK and AVD manager (revision 5), Eclipse IDE for Java EE developers (version 1.2.2), and the ADT (0.9.6). I have checked the Force https box in the settings tab, I also have both an http and https version of the same url. I re-downloaded all components multiple times. I am using Windows XP service pack 3. Anything anyone could suggest would be extremely helpful. You received this message because you are subscribed to the Google Groups "Android Developers" group.

When my app starts often I get this error. Only this one, anything else, and my app works fine.
What does it mean?
ERROR/AndroidRuntime(28130): ERROR: thread attach failed
28130 is the pid, but it is always different from my app's pid.

I have the following problem. I was developing in android using the eclipse and android-sdk-windows saved in an folder (e.g. C:androidandroid-sdk_r07-windowsandroid- sdk-windows and C:androideclipse-pulsar-helios-win32). But after i downloaded and installed the eclipse and android sdk again, in the after folder, i got this error message: "Failed to parse the output of 'adb version' " and can't run my application, because the emutaros that starts is not identified by the eclipse, i can't find it into "Devices" tab from eclipse. I found from the net the following http://stackoverflow.com/questions/2260118/failed-to-parse-the-output "Try closing Eclipse, issuing a 'C:UsersMohitDocumentsAndroidSDKools kill-server' command from terminal and retrying. If that still doesn't work, you could try opening Activity Monitor to see if there are any existing adb processes running, and kill them. but i am using Windows XP and i don't know how to use kill-server command from the terminal. I mean in run/cmd there are is no such a command or how can i use the second solution - to open Activity Monitor from Windows XP

I faced to the serious problem when building my environment. I use below software for compiling. android SDK (android 2.1) eclipse 3.5.2. At first, this problem occurred on eclipse 3.6. I looked for the reason and countermeasure on the web. As the result, I re-installed eclipse 3.5.2. however, the problem was not fixed yet... after building, the below message has been displayed. "Conversion to Dalvik format failed with error 1" if you know other countermeasure for this.

I see a lot of posts about writing to the SD card, but I believe my problem is different. I am unable to create the SD card during the process of building an AVD.
I initially tried to use the Android SDK and AVD Manager to do this, selecting
Name: my_avd
Target: Android 2.2 - API Level 8
SD Card: Size: 1024 MiB
Skin: Built-In: Default (HVGA)
Hardware: Property: Abstracted LCD Density, Value: 160
This pops up a window with the message:
"Result of creating AVD 'my_avd':
Error: Failed to create the SD card."
I tried to repeat the process from the command line, receiving a similar error:
CODE:........
Attempting to follow instructions for using mksdcard was equally unproductive; I think my basic lack of linux experience may be causing me a problem here. When I try to use mksdcard, it just reports that it cannot find the file or directory. Is the mksdcard tool available for use this way in linux?
CODE:..........
I've added the android tools directory to my PATH variable, but I feel like there is obviously something else I'm missing. Perhaps some kind of access rights?
Attempting to run the android command with sudo did not seem to help either:
CODE:..............
I even tried installing Eclipse and the ADT plugin and running the manager from there to no avail. Any tips would be most appreciated. Advanced warning that I am somewhat of a novice Linux user, so even if it seems like a no-brainer obvious thing to check, I could still have missed it.

I'm having a problem with the LVL in one of my apps. Here are the projects in my eclipse workspace: com_android_vending_licensing - standard LVL my_app_1 my_app_2 my_app_3 All three of the apps use the same licensing library project (including the same SALT), and share the same code in their main activities for checking the license. But when testing, one of the apps continuously fails the license request and the others respond correctly depending on what test response I set in the market "Edit Profile" page. The error I get in logcat is: 08-04 15:20:20.863: ERROR/LicenseValidator(4883): Signature verification failed. And the dontAllow() function of the LicenseCheckerCallback is run. This error message originates from line 104 of LicenseValidator.java in the licensing library. I've done some debugging and the responseCode is set to LICENSED (see line 94 of LicenseValidator.java).

I have setup for Android development with 1.5 SDK on Mac O.S X - Eclipse 3.5. I want to upgrade the SDK, so as i followed to choose Window->Android SDK and AVD Manager from Eclipse. But it throws error as follows: XML verification failed forhttps://dl-ssl.google.com/android/repository/repository.xml.Error: cvc-elt.1: Cannot find the declaration of element 'sdk:sdk- repository'. Failed to fetch URL I tried "http" instead of https, but still getting the same error. I don't know why such crap error comes. If i see Android website, http://developer.android .com /intl/zh-CN/sdk/index.html its confusing.Could someone guide me easily to update Android SDK to 2.x or later without uninstalling my current setup environment.

I've been trying to use Eclipse and the Export Wizard to create a signed apk. unfortunately, I cannot seem to generate an UNSIGNED apk. Every time I "clean and build" I get the error below, which I read I can get rid of by "reload" or refresh then building again. however, the debugger automatically signs with the debug key after I do this, defeating the purpose. how do I build the apk w/o signing it?

In my Android appliction in eclipse I get the following error:
UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: Lorg/xmlpull/v1/XmlPullParser;....
Conversion to Dalvik format failed with error 1
This error only appears if I add a specific external Jar to my project.
I search long time to the right solution but all possible solutions don't work.
I even tried to change to android 1.6 instead of 1.5(current version I use)

I have a working(Released) project that needs some updating. The Project was created with SDK 1.1 on Windows and Ecplise 3.4. A couple months ago i moved away from Windows to Mac and installed all tools on the mac including Android SDK 1.1. Everything was working fine at that time.
I never bothered compiling the project against SDK 1.5 as the program was running fine on a 1.5 Device. But now i need to do some changes and installed SDK 1.5, following the installation guideline (http://developer.android.com/sdk/1.5_r1/ upgrading.html#UpdateYourProjects).
So I build my project against SDK 1.1 (as suggested) and failed with the following error messages : - no classfiles specified - Conversion to Dalvik format failed with error 1
I receive the same error if I compile with SDK 1.5 (clean + build).
First i thought there is something wrong with my code but could not find anything. After that I tried the example JetBoy and received the same error. Using "Fix Project Properties" was without effect for booth projects.

Anyone know why I would be getting the errors below. The message below is showing up in the Console view, and I'm getting a "Conversion to Dalvik format failed with error 1".
My app has been working quite well for some time, and I just tried to update the SDK and DDMS to 0.9.9, and now it won't build.
I've done a search for the CharBuffer class and don't find any matches in my files, but I am using several API's (BUMP, C2DM, Admob). I definitely don't use any of the core-library in my code. If the error message is correct, I just can't quite figure out how to tell which API is the problem without almost wiping out my code base, or starting a new project and copying a few files at a time.
Oh... but the two files at the bottom of the file are missing android-6sdk.properties and android-5sdk.properties. Anyone know where I find them?
I have tried uninstalling and reinstalling but so far, no joy :).
CODE:.........................
In something other than a core library. It is likely that you have attempted to include in an application the core library (or a part thereof) from a desktop virtual machine. This will most assuredly not work. At a minimum, it jeopardizes the compatibility of your app with future versions of the platform. It is also often of questionable legality.
If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine distribution, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message.
If you go ahead and use "--core-library" but are in fact building an application, then be forewarned that your application will still fail to build or run, at some point. Please be prepared for angry customers who find, for example, that your application ceases to function once they upgrade their operating system. You will be to blame for this problem.
If you are legitimately using some code that happens to be in a core package, then the easiest safe alternative you have is to repackage that code. That is, move the classes in question into your own package namespace. This means that they will never be in conflict with core system classes. If you find that you cannot do this, then that is an indication that the path you are on will ultimately lead to pain, suffering, grief, and lamentation.

Not sure what is going on. Running Windows Vista x64. Not had really any problems with eclipse. I had to upgrade to 1.5 and when I did that I got all kinds of install errors. So I said 'f-it'. I decided to start over and downloaded the 1.5SDK, downloaded the Eclipse for Java, Not Eclipse classic (someone said that was an issue). So now I have Eclipse for Java (or something to that name). Each time I try to compile it says 'Unknown Error: SDK is not loaded yet'
