Android :: Segmentation Fault On Emulator Startup?
Nov 23, 2009
When I start the emulator with the command emulator -avd Android2.0 it comes up with Segmentation fault (core dumped) if i start it without sound it works emulator -no-audio -avd Android2.0. I'm using Fedora Core 12 64bit. If i run emulator -verbose -avd Android2.0
.................
why the emulator is getting a problem with sound? I'm trying to write an app that uses sound so really need to get this working but i'm stumped.

So i've been trying to flash modules from within the phone without having to boot into the recovery, and i found that i can just extract the update-binary and execute it through shell and it will do the trick!!
However, know im trying to do that through my app, I successfully got root access using Chainfire's libsuperuser, however, whenever i send the commands to run update-binary i get "segmentation fault(core dumped)" Error.
the command i using in both shell and from within the app is "./update-binary 3 stdout ./modules.zip".
This might be irrelevent but when ever i add a number before stdout (e.g 7stdout) i get segmentation fault during shell as well, other than that, i can't find the problem.
This is a logcat of the process through strace, if we have a linux debugger here
Code:
08-24 17:06:43.568 8703-9188/com.thunder.kernel.lighter D/libsuperuser: [libsuperuser][SU*] execve("./update-binary", ["./update-binary", "3", "recovery", "./KernelLighter.zip"], [/* 24 vars */]) = 0
08-24 17:06:43.573 8703-9188/com.thunder.kernel.lighter D/libsuperuser: [libsuperuser][SU*] gettid() = 9202

I've been modifying/editing parts of the Android platform, but have run into a problem when trying to test my edits. After making my changes to the platform source, I was able to successfully compile the source - thus creating system.img, ramdisk.img, and userdata.img. When I go to test this in the emulator, the emulator just hangs on the "ANDROID_" screen, with the underscore blinking, but never seems to load. Any suggestions? The command I used to run the emulator is as follows:
./emulator -system $HOME/android/platform/out/target/product/generic/system.img -ramdisk $HOME/android/platform/out/target/product/generic/ramdisk.img -data $HOME/android/platform/out/target/product/generic/userdata.img

I succeeded in compiling emulator source code on msys. but it could not run on msys (winxp) when type "emulator", prompting words below: ./emulator This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. If type "emulator -verbose", following information shows: $ emulator -verbose This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. If type "emulator -debug", window shows android emulator usage like below:
$ emulator -debug unknown option '-debug' Android Emulator usage: emulator [options] [-qemu args] options: -system <dir> search system, ramdisk and userdata images in <dir> -kernel <file> use <file> as the emulated kernel -ramdisk <file> use <file> as the ramdisk image (default is <system>/ramdisk.img) -image <file> use <file> as the system image (default is <system>/system.img) -nand0 <file> obsolete, same as -image -data <file> use <file> as the working user data disk image ..............................................?

As u know, since android 1.6, there are not dirs on dirs like HVGA-L. Instead, there is only one dir like HVGA. That is, HVGA-P and HVGA-L are merged into one dir, HVGA. So, only HVGA can be selected and by default the emulator is started with portrait mode. Though I can press CTRL+F11/F12 to switch it to landscape mode, I do not like it. What I want is to start the emulator with default mode of landscape. Would anyone know how to do it?

Every time I start my phone it seems that every program in the app catalog starts up. Until I activate the Advanced Task Killer and shut them all down, the thing runs like a hog. I have quite a few programs installed, but I dont use them all all of the time. Why do they all start up and is there any way beside the ATK to stop them? Is there any way to modify the startup files?

i have a aplication on the android market, in wich exceptions and errors are catched and sent to me by acra. But i receive quite a lot out of memory errors.. In different kind of classes...some my app, some general java.. Does this always mean there is a problem in my app, or can it also be the phone ran out of memory due to a other process? Will users also get a fc dialog?.....................

We have been using XMLRPC for android and it was working well until we got our hands dirty with Base64 encoding for byte[] (images) -- (we did base64_string.replace("/","$$") for transmission). We have tried undoing the changes and its looking like an XMLRPC error. We are getting the following error in the DDMS:
06-10 23:27:02.970: DEBUG/Test(343): org.xmlrpc.android.XMLRPCFault: XMLRPC Fault: [code 0]
06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCClient.callEx(XMLRPCClient.java:308)
06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCMethod.run(XMLRPCMethod.java:33)
Just before this I checked the body (xml message -- which is perfect) and the response received:
06-10 23:27:02.940: INFO/System.out(343): Response received: org.apache.http.message.BasicHttpResponse@437762f8
Since the message is not even reaching our cloud, the issue is mostly with XMLRPC for android.

Im getting this error caused by VM( logcat below from emulator, it also happens on the device) This is a know bug filed at least 3 times with different issues. I am getting it if I close my app and then open it a few times(it happens too often), you can close the app by "back button". I also have a service running in the background which updates my widget( i stop the service when it finishes), which launches an activity through a PendingIntent. Is there any workaround for this error, if I know what causes this exactly i may be able to prevent it, something must be triggering this....................

T-Mobile UK user here. I've searched through this forum but can't seem to find anyone else reporting this.I've had a G2 for approx 3 weeks now, however, the thing just won't sync Gmail as it should - either via Auto-sync or by manually trying. I've had a G1 for the last 12 months so feel experienced enough to know when something's not quite right. I am using the G2 in exactly the same locations as the G1 so it cannot be a reception issue. I've tried sending test emails from my work email address to my Gmail account: Out of the 10 test emails sent over the space of 8 hours, only 2 came through (the G2 was on Auto-Sync the whole time). The others eventually came through via a combination of manually instigating Sync (1 success) or, in most cases, having to switch the phone off and on - even this only worked twice. Whenever I sent emails from work to G1 they would appear on the phone instantly. There isn't a prob with the emails leaving my work domain as I can see that they have all been delivered successfully viewing my Gmail account over the web. If I leave the phone on the Data Synchronization screen, the round sync indicator is constantly running next to "Google Mail" and intermittantly pauses with the error message that "Sync is currently experiencing problems. It will be back shorlty". have also found that the reception doesn't appear to be as good as the G1 - I work in central London and live 10 miles south of the river.I'm running FW 1.5 Kernal 2.6.27-a5504199 Software 1.0.0.A6288

This morning I installed update 2.17.61.2 and since then I've noticed a fault with the auto-rotation feature. For things such as internet, SMS inbox, email inbox etc. the screen view is stuck on landscape and will not auto-rotate back to portrait when I tilt the phone
Also I tried playing Teeter and the ball doesn't move no matter how much I tilt the phone. I've tried resetting the G-Sensor Calibration but it doesn't resolve the fault.

My Vibrant just crashed with this message, "user fault not kernel panic upload mode". All I was doing was updating a word document using the application FREETHINK which comes with the phone. I pulled the battery out and restarted, and went to do the same thing I was trying to do before the crash and it crashed again.I looked this message up online using "google". There isn't much. People seem to think it has to do with GPS, and it seems like it's a reoccurring problem, which factory reset will not fix. I'm switched back to my Blackberry, incase that it does reoccur. And I will call T-Mobile I guess or maybe try restarting again, and see if it crashes again doing something different other than FREETHINK.Not panicking yet.Anyone else experiencing this problem?I hope it doesn't reoccur,I'll let you know.

I created a sqlite database to store playlists for a media player I am developing because of extended feature (rather than using the Content Provider).

Finally strace gave me this:
CODE:................
And several other attempts to call "link" that also fail (sshfs does not support hard links).
Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

I need to run several emulator instances to test my application. When i try to run instances using emulator -data <path> option, the emulator crashes.
I got a MS Visual Studio window informing that emulator throws a "unhandled win32 exception".
The exception message in the debugger (MS Visual Studio 2008) is: "Unhandled exception at 0x77c4706c in emulator.exe: 0xC0000005: Access violation reading location 0x03216848"
The emulator runs normally without "-data" option.

Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?

I downloaded the most recent version of Android for linux (android-sdk_r05-linux_86.tgz). I was trying to use the the Android Ant task(s) for packaging, building, and deploying my code. I should mention that I'm running AMD64, but have the 32-bit libraries installed. The Android Ant tasks are all broken.
First, the start-emulator task never gets the emulator running. It does get past starting adb, but then just sits there.
Second, the SDK is missing the aapt binary in the tools directory. So, the example notepad sample application will not even package correctly.
I have all the dependencies configured for Android. I can run it from the command line just fine.I assume the Ant code is out of sync with the recent SDK updates. Can anyone shed some light on this problem? At this point, I'm considering writing my own Python scripts to interact with the Android SDK. Ugh.

Is there any way to get an app to run at startup? There is a volume control app (ladybug icon) that I use to keep my ringer volume always at vibrate. When I accidentally hit the volume rocker, the app returns the ringer to vibrate. However, I must remember to run the app when I restart the Droid. So, is there anyway to have it run when the Droid powers on? Or is that something that would have to involve rooting?

Other than downloading a 3rd party application that auto-starts apps on boot, is there a way within the OS itself to autostart programs when the phone reboots? I have a few apps I use for work and would be nice if they autostarted on my Droid without having to launch each one independently.

I have Listpreferences in my app. They don't appear to be setting to their defaults right after installation - they appear to be null. I'm trying to figure out why my default preferences are not being set right after installation.
In my main code I have:
CODE:......
Right after the above code executes, each variable contains "defValue" instead of the actual values I have assigned in my ListPreference below.
My preference xml file is called, "settings.xml". Here's what one of the ListPreferences there looks like:
CODE:.............
Here's what some of my strings.xml file looks like:
CODE:.................
When I go to menu, and then settings, I can see my defaults checked (radiobuttoned). Then when I go back from the settings menu to my main screen - all is well - for life! ...then each var above is assigned the proper default value.
This only happens when I first install my app on the phone. After I go to the settings screen once and then right out of it, the app is fine and accepts any setting changes.
By the way, as you can see, "List1" is the android:key within a file called settings.xml in my res/xml folder.

1) I have a Spinner with several options provided by an ArrayAdapter and have an onItemSelected listener on this Spinner. When selecting an item from the spinner, I want to display another view (list-view) but this method is unintentionally invoked upon initially displaying the view. The list-view is therefore displayed upon startup of the application. It is possible to add a spinner-on-item-select listener that won't fire upon initially displaying the view but only by the user selecting an item?
