Android :: How Can I Catch SIGSEGV - Get A Stack Trace Under JNI On Phone?

Jul 4, 2009

I'm moving a project to the new Android Native Development Kit (i.e. JNI) and I'd like to catch SIGSEGV, should it occur (possibly also SIGILL, SIGABRT, SIGFPE) in order to present a nice crash reporting dialog, instead of (or before) what currently happens: the immediate unceremonious death of the process and possibly some attempt by the OS to restart it. (Edit: The JVM/Dalvik VM catches the signal and logs a stack trace and other useful information; I just want to offer the user the option to email that info to me really.)

The situation is: a large body of C code which I didn't write does most of the work in this application (all the game logic) and although it's well-tested on numerous other platforms, it's entirely possible that I, in my Android port, will feed it garbage and cause a crash in native code, so I want the crash dumps (both native and Java) that currently show up in the Android log (I guess it would be stderr in a non-Android situation). I'm free to modify both C and Java code arbitrarily, although the callbacks (both going in and coming out of JNI) number about 40 and obviously, bonus points for small diffs.

I've heard of the signal chaining library in J2SE, libjsig.so, and if I could safely install a signal handler like that on Android, that would solve the catching part of my question, but I see no such library for Android/Dalvik.

Android :: How Can I Track Down A Crash In A .so Without A Stack Trace

Sep 20, 2010

My game is crashing on the HTC Hero and I have managed to get a user to send me their log. I don't see a Java stack trace at all. It looks like it's crashing in the OpenGL driver. I was wondering how I could go about trying to determine the problem. I was thinking of adding that acra project that sends crash reports to a server but I am thinking it will just send the same that is in this log. I have error checking everywhere so I am really at a lose where to go from here. I even went out and bought a HTC Hero but Canada only has 1.5 for the OS. Code...

Android :: Stack Trace Does Not Reference Application

Dec 16, 2009

So I have an app on the market with >10k active users. I have recieved maybe 50 complaints from Droid-user that the program crashes arbitrarily. I have not been able to replicate the error with my own droid, but I got one of the to send me this crash log. However, it does not reference the application. Do you have any suggestions on how to track down this error? I stand baffled.

Android :: Development - Debugging Tools / Generate A Java Stack Trace?

Apr 29, 2010

Is there a way to achieve the following in Android?

1. generate a Java stack trace in Android. In J2SE, we use to use something like this - send a signal to the Java Virtual Machine; the Java Virtual Machine generates a stack trace for you; or we can also use debugging tools or Java API calls.

Android :: Stack Trace Gives Hex Values Not Function Names When Core Library Crashes

Feb 12, 2009

Here my application "com.android.hello" calls a core library "libvt.so" through JNI call. There is a segmentation fault in "libvt.so". When executed I get the following log What I see is some Hex value followed by a library name. #00 pc afe0d24c /system/lib/libc.so

Also there is a Stack section 01-01 00:02:57.800: INFO/DEBUG(1600): stack: 01-01 00:02:57.800: INFO/DEBUG(1600):bef2e570 bef2e604 [stack] 01-01 00:02:57.810: INFO/DEBUG(1600):bef2e574 afe0a333 /system/ lib/libc.so

This too gives similar information. I am looking for little more informations rather than Hex values. Like the backtrace feature where the stack hex values is mapped to the function names and function names are visible.

Please provide information how to see the function names in stack rather than Hex values. Is ther any compiler options needs to be updated? Any makefile to be updated to enable backtrace?

Android :: How To Print Stack Traces For Exceptions?

Does anyone know how to print stack traces for exceptions caught while running in the Android emulator in Eclipse? I catch the exception and call .printStackTrace() but I cannot find where it is being written. I have tried .printStackTrace(System.out) and .printStackTrace(System.err). I would be nice to be able to direct them to the Eclipse console.

Android :: "Out Of Memory" / No Useful Stack Trace

Apr 11, 2010

My android app is getting an "Out of memory" error without a useful stack trace. It occurs after I have repeatedly re-invoked its main logic through a menu interaction, which leads me to believe that there's a memory leak somewhere.

I say that the stack trace isn't useful because it doesn't include references to any of my own code. There are no references to my own code in the logcat output, either.

I'm wondering if any of you can help me figure out where my memory leak might be occurring, given my stack trace and my logcat output.

Here's the stack trace: Code...

Could my error be related to the "Window already focused ..." warnings? If so, how can I find out what is causing these? I know that I could sprinkle my code with lots of calls to Log.v() in order to zero in on where my problem might be occurring, but I'm wondering if there is a better way to get more meaningful information about the cause of my memory leak.

Android :: Print To PDF (For Future Use) On Phone Possible?

Jun 27, 2010

When shopping online or checking into a flight online. I like to be able to save the receipt screen (or boarding pass screen) to a pdf, so I can easily access it later or print it off. This is easy to do on a laptop with cute pdf or similar. Is there any way to "print to pdf" on an android phone? Or to put it in other words, is there any way to save a webpage as a pdf, so it can be opened again later (and look exactly the same)?

General :: Print Or Synch Phone Calendar Entries?

Jan 29, 2012

I've been using the *phone* calendar to make appointment reminders when I'm out and about. Now, I need to print those out for the past six months and I've searched all over--it doesn't seem possible.

Is there some clever poorly documented way to either PRINT the phone's calendar appointments? Or to synch them to another app on the PC, like Outlook, or the main Google Calendar account, so that they can be viewed and printed from the PC as well?

The information from my own Google Calendar shows up on the phone--but the phone's calendar appointments don't show up on except from the phone, where they can't be printed out.

HTC Droid Eris :: How Phone Processors Stack Up Against Computer CPU?

May 23, 2010

My first computer was a hand-me-down from my father. It had a Pentium II, 200ish mhz. I think it had 64 MB ram and a 2 gig hard drive. I'm pretty sure that my Eris is faster and better than this computer in every respect except for screen size, but I wonder, how does the Eris's processor compare to other x86 processors out there? Has anybody benchmarked arm based CPUs against old pentium CPUs? Does anybody know how our phone processors stack up against computer processors?

Tried putting the phone in and out of flight mode by holding down the power button and selecting the flight mode option, the option turns grey after I press it, won't allow me to press it again and seemingly does nothing. Press the off option and turn the phone back on and it's fine. Now I reckon I had suffered this with earlier firmwares.
