Android :: Traceview And Dmtracedump Fails To Start
Apr 3, 2009
Tried to trace for the first time but got the following exception when I started the "traceview" application with my trace file. mane@Labbe:/tmp$ traceview gldraw.trace Exception in thread "main" java.lang.RuntimeException: Method exit (java/lang/BootClassLoader.getInstance ()Ljava/lang/BootClassLoader;) does not match currentmethod (dalvik/system/VMDebug.startClassPrep () V) at com.android.traceview.ThreadData.exit(ThreadData.java:116) at com.android.traceview.ThreadData.handleCall(ThreadData.java: 78).....

When I try to start an emulator from Eclipse (Android SDK setup application) with the scale parameter it just fails. Second Command Prompt screen (which I think is actually a Java app) shows some exception but it closes itself right after. This is very annoying because without the scale, WVGA emulator does not fit on my laptop's screen. Any idea how to fix this? And when I try to start an emulator from Command Prompt with the scale, it works.

I am using an AsyncTask to fetch the ring tone for a contact when my application starts, it works fine until after my Activity closes a couple of times during the AsyncTask, after this happens the AsyncTask will only ever get to onPreExecute() and never doInBackground, so I can never fetch the ringtone then until either a force stop or device restart.
Why this might be happening? Why the AsyncTask would get to onPreExecute but then never run doInBackground()?
Here is my code: (Following the Shelves source code)
CODE:.....................
And onAddRingtone() is used in onCreate and onCancelRingTone() is used in onDestroy() as well as where you can see if in the code above. I have spent 3 days on this and I haven't been able to find a solution? Am I taking the wrong approach? Using cancel wrong? Is there a bug?

I'm running the basic HelloActivity from the SDK 2. samples. When I try Trace view in the DDMS prespective its generate the trace file but can not opened. "'/sdcard/com.google.android.apps.uploader.trace': Permission denied".

I tried to use traceview on a computer with a 64bit processor, the error I get is "architecture word width mismatch": I do use the 64bit version of Eclipse for development, I know SWT works on my computer. What do I need to do to make traceview work on my computer? For now, I copy the trace files to my laptop, which has a 32 bits architecture. android-sdk-linux_x86-1.5_r2/tools/lib/libswt-pi-gtk-3236.so: /home/ christine/java/android-sdk-linux_x86-1.5_r2/tools/lib/libswt-pi- gtk-3236.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1767) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676).....

I have been trying to use traceview for profiling my Android app. So far I have gotten it to work on very small parts of the program. If I use it for bigger chunks it creates too much information (.trace file is too large) and I get an OutOfMemory (heap memory) error from the java compiler. I tried some tricks with setting higher min and max heap memory values but no luck. If anyone has used traceview with similar effects before. I would highly appreciate any tips you may have. Here are the details. First I am reproducing the error message: $ traceview.bat tmp.trace Exception in thread "main" java.lang.OutOfMemoryError:.....

We know that it's very convenient to use TraceView in Android java code to check the runtime of different chunks of code. Now I develop my app with NDK and I want to check the runtime of some native functions, but I found nothing in TraceView guide if it's possible to use this tool. Because I noticed that one of my native methods spent too much time and I want to dig out the more detailed root cause. Is there anybody know if we can use TraceView in native code?

I am getting complaints about my app's performance and want to get to the bottom of it. I am not really sure how to use traceview for that. I'd like to sketch how I used it and maybe you can give me some advice what to to differently and what to look for in the traceview output. The case: I have a list activity that lists articles. When clicking on one of the articles another activity is started that shows the article itself. I measure from the moment onClick() is entered on the ListActivity until the moment onResume() is about to be left in the Show Article Activity. I have two cases that I measure: "Cold" means the app is running and the ListActivity is started, but the Show Article Activity has not been called yet. "Warm" means the same, but the Show Article Activity has been called before during the runtime of the app. Here are the traces:.......

I'm usign starMethodTrace() and stopmethodTtrace() to get trace data to use on traceview. Everything seems to work fine. I test my app for 50 (real world) seconds having two important events after 15 and 45 seconds from start tracing. However, when analyzing the traceview's timeline I found the total tracetime is only 1.068,964 (msec). My two events are displayed as they were occurred at time 257,743 msec and 642,654 msec. This is just about 1 second of total execution time. Why there is this huge difference between real world time and trace view time? May be because I have a lot of idle time? Is there a way to relate the times displayed in the time line with real world time?

I'm using traceview to identify bottlenecks in my app. If I use the emulator, everything works fine. But when the device is used, no matter how long I run the app, traceview only gets the initial 5 seconds of my session and nothing more. I also noticed an error message in the console: Traceview: (<unknown>:10301): GLib-WARNING **: g_set_prgname() called multiple times. Have you ever experienced this problem?

I'm working with an OpenGL ES app in Android, but when I want to use traceview to profile my code, I always obtain the following error: ThreadData: 'android/XX/XX' call time (xxxxxxxx) is less than previous time (xxxxxxx) for thread '[3] main'. I've tried to call Debug.startMethodTracing() and stopMethodTracing() in different places of my code but it never works, anyone can help?

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 upgraded my phone's images to Android 1.5 images (from http://www.htc.com/www/support/android/adp.html) Now when I try commands like adb remount, chmod, adb push etc I get "Operation not permitted" and "Permission denied" errors
I was able to give this command when I had 1.0 images flashed on my phone.
Has something related to permissions changed with Android 1.5?

I'm trying to do is open a very simple application that is supposed to do nothing but display an imageView above a textView. The application worked fine until I added the imageView so I'm assuming my problem has something to do with that.
Here is the code:

When I try to install the android SDK it fails to install.
My OS is Windows XP. I just downloaded and installed Java JDK 1.6 Java -version from the command line returns: http://stackoverflow.com/questions/ask java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)
My environment vars have: JAVA_HOME=c:progra~1javajdk1.6.0_11. I downloaded android-sdk-r04-windows.zip. I unziped it in V:AndroidInstall
When I go to the V:androindinstallandroid-sdk-windows> and type "SDK Install.exe" nothing happens...If I go this from graph
When I do this from a graphical file viewer I get a quick flash that looks like a command line window and nothing....
When I try to run android list targets from the tool directory I get:
Error: Error parsing the sdk.
Error: V:androindinstallandroid-sdk-windowsplatforms is missing.
Error: Unable to parse SDK content.
So the basic install setup is not happening.
Additional clues:
I have a G1 and Android 1.0 was running on this machine. (Almost a year ago) I've updated my G1 to 1.6 so I thought I'd update my SDK before starting new development.
When I tried to upgrade it tried and then died as the "directory was in use"
So I cleaned out all the android directories, rebooted and redownloaded everythign from scratch.
Now it won't run at all.
I've clearly got something in an unhappy state, but I've cleaned up all the directories and no remanants seem to be running I've rebooted....

I'm using the SAX parser to read some RSS feeds and have found a problem. Some feeds, for example CNN Money Top Stories, have embedded some characters in their content, i.e. the copyright symbol. Well, that's not valid XML and the SAX Parser fails with an exception "invalid token". The only help I have seen given is to fix the XML at the source and that's not an option obviously. So, I can think of 2 options and they both stink:
(a) read the content first, scrub it, and then pass it to the parser.
(b) Use DOM instead of SAX.
What I *want* to do is make the parser a little more forgiving and just accept or discard/ignore the bad text. I'm not have any luck with setErrorHandler. My error handler does not get called.

I recently upgraded my SDK from 7 to 8. One of my applications uses Google GeoCoding, specifically the Geocoder object. After the upgrade, when I call the getFromLocation method, it doesn't return any addresses and I see a message in the logcat to the effect that GLS failed with status 20. My Google Maps API key is working fine because I'm seeing the map tiles, but GeoCoding is broken. It works fine if I run a previous (SDK 7) build of my app.

I want to upload an upgrade in the market. But when I upload the apk and new images and click save or publish everything is lost when I return to the listing (the old apk and images are restored). The only thing that changes is the saved versioncode of the app. Is there something broken?

The following code works when I either have no min sdk version specified in the app manifest or if it's 5 or greater. But if I set the min sdk level to 4 (Android 1.6) , it fails to create a subdirectory in the sdcard.
There is no error. mkdir() or mkdirs() just returns false.
CODE:....
Am I doing something wrong here? Or is this a bug? I'd prefer not to set the target to 2.1 and min version to 1.6. But right now, I have to set it to 2.0 for it to work.

I am brand new to developing for android and have hit something of a stumbling block that I cant seem to get around.
Using the NotePad example, I have created my own ContentProvider to serve up data from a database that I will eventually host on a webserver. But that is lightyears away from where I am right now.
Just testing my ContentProvider has caused a bit of a headache that I cant solve. For some reason, when the provider calls SQLiteDatabase db = mOpenHelper.getWritableDatabase(); I get a null pointer exception.

I'm testing an app I'm developing and asked a friend to install on their device. I wanted to make it as easy as possible for them to help me out so I put the .apk up on my website for them to download to the phone (rather than making them download the SDK and use adb to install). The install of the downloaded .apk fails, complaining of a package conflict.
I have since gotten my hands on the phone briefly and I verified that:
* they have selected "allow unsigned apps" in settings
* there is no package with the same (or similar) name in data/data * installing via adb works with not a peep
* when I download the .apk to my phone the app installs fine.
It would be really nice to make it as easy as possible to distribute to people who might be willing to do me the favor of testing.

I tried connect to AP(DHCP componet is disabled) with Google dev phone 1. It fails to connect to that AP. Can't get a ip address from AP. I hoped the dev phone successfully connect to the AP, and assign own auto-ip by itself(169.254.xx.xx). But It didn't happened. I think it must be abnormal case. Is there any special way to get an Auto IP address?

I have a and Android project and its test project. I can run tests successfully in the emulator. As the Android project has dependencies on a third library project, I want to use classes of the third project in the test cases too. For this, I need to add a dependency from the test project to the third project as well. Compile-time this works, but when I do a remote run of my AndroidTestCase, all tests fail. For each test, I get a NoClassDefFoundError, but not for third project classes, but for a class in the Android project itself!
