Android :: Traceview Out Of Memory
Jun 15, 2009
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:.....

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". Do I need a permission to write in the SD card? 4:38.380: INFO/dalvikvm(10434): Debugger has detached; object registry had 1 entries 11-20 21:34:38.380: DEBUG/dalvikvm(10434): VM cleaning up 11-20 21:34:38.411: ERROR/AndroidRuntime(10434): ERROR: thread attach failed 11-20 21:34:38.466: DEBUG/VoiceDialerReceiver(1225): onReceive Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.example.android.helloactivity flg=0x20000000 cmp=com.android.voicedialer/.VoiceDialerReceiver (has extras) } 11-20 21:34:38.466: DEBUG/dalvikvm(10434): LinearAlloc 0x0 used 636716 of 5242880 (12%) 11-20 21:34:38.490: WARN/ResourceType(1015): Resources don't contain package for resource number 0x7f080000 11-20 21:34:38.490: WARN/ResourceType(1015): Resources don't contain package for resource number.....

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).....

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)?

My application is designed to support both portrait and landscape orientations. Using my HTC IO device, it survives 12 orientation changes before throwing an out of memory exception while inflating my activity.When I follow the recommended procedure of using DDMS to first force a GC and then write a heap dump, and then load it into the Eclipse Memory Analyzer, there is only one retained instance of my application, as there should be. None of the other retained objects are obvious offenders. Just for yuks, I reran the test, and did everything the same way except I didn't force a GC. In this case I see 13 instances of my application, which is more consistent with throwing an OOM exception. Is this telling me something useful? If forcing a GC with DDMS reclaims the memory used by now-defunct instances of my activity, I would have thought the VM would have garbage collected some, if not all of these defunct activities automatically. Do I need to request GC at the very beginning of my activity lifecycle to make sure?

Not had my desire long but down loaded a few apps for it they all seem to be stored on phone memory not the sd card. what is stored to the sd card seems to be unused so far. do you have to set it up to use sd card or does it know one is fitted. does it switch to sd card when phone memory full. will run out of space soon if can't get things to store to card instead of phone mem.

Here's the proof of the madness. I deleted several space hogging applications and it hasn't gone away. I have also power cycled and messed around with a few settings and the low storage warning will not go away.

I have a problem with a strange out of memory exception that only occurs on some devices (mostly HTC Desire). It happens there every time a user starts a certain activity (no matter how - there are two paths to that activity) and i'm really puzzled as to why (i checked for leaks and couldn't find any)...
The error is either thrown when calling setContentView or shortly after.
This is the code block that throws the error:
CODE:.........
As i said - the error is usually thrown when calling setContentView or when calling getMonthTimeStamps()
getMonthTimeStamps is a helper function which creates a list of dates available in the internal database. It creates a couple of (small objects) and returns an ArrayList.
Here is the function:
CODE:.............
I'm not claiming that my code is flawless or perfect, but i really don't understand why this error is thrown. The XML-layout doesn't contain any references to images and not very complicated (textview, spinner, tablelayout).
Here is the error log i received from one user:

I am using a ListActivity. Each list entry contains an ImageView and a TextView. I have a huge list and has been getting Out of Memory errors once I scroll through a fair amount of them. I figured I need to reduce the size of the images but I am wondering what happens to the objects once the list entry is hidden from view (as i scroll down the list). I have read somewhere that the list entry objects are automatically re-use. But what happens to the drawable images which were loaded into the ImageView? IF the ImageView object is reused, what happens to the binary image? Are they freed automatically? How do I prevent the OutOfMemory exception? I want to do something similar like the Android Market. As one scroll downwards the images are loaded and new entries are loaded. The Markey can have a long list which one can scroll down and all the way back up again without any problem. The only difference being mine throws OutOfMemory Exception. Advice anyone?

I'm contemplating making an android version of my iPhone app. One of the attractions is the availability of a micro/miniSD card from Spectec that has an Ant+ radio in it, to communicate with Ant+ protocol devices.
The technical feasibility of this is not my question; but rather its practicality:
This obviously involves taking out the SD memory card in the handset and replacing it with one with no on-board memory, leaving the device with only the builtin 256mb or whatever. this is plenty for my app, but I'm concerned that, aside from annoying the user by having all their music removed, there will be apps on the users device that save data to the SD and will be broken by removing the SD memory.
