Android :: Print Backtrace When Debug Native Code

Nov 23, 2010

When I debug android app, if I work with Java, I can use Log.d("TAG", "xxxx", new Throwable()) to print backtrace of Java code. This is really handy for me to find bugs. But when I work with native library (e.g. libwebcore.so), there seems no way to print backtrace in runtime. The only way to debug native code is use gdbserver.

I have a question: Is there any way to print backtrace in C/C++?

Android :: Debugging Native Code (C++) Using Gdb With Eclipse / Is It Possible?

May 24, 2010

I have some piece of code which uses JNI. I can debug code wrote in Java directly in Eclipse (using ADT). I even have a script, which help me debug native code with gdb. However this is not very comfortable way for doing this.Is it possible to configure Eclipse to use gdb (I guess gdbserver) for debbuging android native applications? Do you know where I could find any description of this?

Android :: Stack Tool For Android Dev - Debug Native C++ Code

Sep 12, 2010

I am writing an android game that involves some c++. I have a fairly repeatable crash that seems to be due to my c++ code

Looking at the page:
http://source.android.com/porting/debugging_native.html#Debug_Scenarios (right at the end)

it says to run the output through the "stack tool" - which I can find no trace of.. nor aproto.

Android :: How Can I Debug Without Using Eclipse?

Nov 8, 2009

I have mostly been avoiding debugging when I can because of these two problems, so hopefully someone here has suggestions to avoid them:

1. It seems that I have to build the SDK (`make sdk`) and copy it off to a directory for Eclipse to use almost every time I want to debug. I haven't followed through the "sdk" directive, so I'm not clear on why this is necessary instead of just having Eclipse read from the source in my directory. Isn't there some way for it to do this? FYI: I have a (modified) full checkout of Donut, not just the SDK.

2. How can I debug without using Eclipse? I would really like to be able to use something like gdb/jdb.

Android :: Debug To Use Device With Eclipse / ADB?

Jun 11, 2010

I've been developing on the simulator, but now I have a real device.

adb can see the device (from adb devices), and I've installed Eclipse/ ADB.

I can't work out how to get debug to use the device instead of the simulator though.

Android :: How To Debug Launcher Activity In Eclipse

Apr 16, 2009

I am trying to following this documentation 'http://source.android.com/using-eclipse' to debug android Launcher Activity in eclipse.

It said' You may need to open the Debug perspective (next to the "Java" perspective icon in the upper-right, click the small "Open Perspective" icon and select "Debug"). Once you do, you should see a list of threads; if you select one and break it (by clicking the "pause" icon), it should show the stack trace, source file, and line where execution is at. Breakpoints and whatnot should all work.

My question is which threads I need to select in order to debug Launcher Activity? I don't see a thread name Launcher.

Android :: Eclipse - Debug Configuration - Device?

Jul 10, 2010

I have set up a "Debug Configuration" to debug my Android project. However to get it to debug on a device (HTC Desire) I have to set the Configuration's "Target" to "Manual", there seems to be no way to set in the Debug Configuration that it should go to a selected Device.

It does work, but each debug session I have to "Manually" choose the HTC device from the dialog. Can I set it to always to go the Device?

Android :: Way To Debug Kernel Code?

Sep 10, 2010

I've got some trouble with the media backend (mostly Stagefrightplayer) in Android, and I'd like to understand why it throws the errors it does. The errors are usually device spesific, so debugging on an emulator wouldn't be sufficient.

Example:

CODE:.................

Example 2:

CODE:.............................

I've also gotten the player to bork completely and spit out a traces.txt.

Is there a way to debug what's happening, just like I debug Java code?

Android :: Best Way To Include Debug Code?

Apr 27, 2010

I am programming Android applications, and the best way here may or may not be the same as Java in general.I simply want to be able to set a debug flag that will only execute certain portions of code when it's set to true equiv to C++ setting a preprocessor #define DEBUG and using #ifdef DEBUG.Is there an accepted or best way to accomplish this in Java?

Right now I'm just going to set a variable in my Application object, but I don't imagine this is the best way.

Android :: Debug App On Device With Eclipse And Password Protected Keystore?

Feb 17, 2010

I uploaded my application to Market and then downloaded it to my phone. Now I'm unable to use debug keystore which is used by default by Eclipse ADT Plugin (Re-installation failed due to different application signatures) and when I'm trying to setup own keystore in Eclipse->Windows->Android->Build->CustomDebugKeystore, I'm unable to enter password or accept keystore and type password later. Is there anything I can do or only way do debug app on device is to uninstall market version and deal with default debug keystore?

Android :: Eclipse Debug Issues While Coding Phone Applications

Sep 27, 2010

I have an application I am writing for Android that basically does a screen scrape of a large table on the web and presents it in a nicer way on the handset. Its 500k of html and takes about 20 seconds or so normally.

When I have my phone hooked up to the computer, I used to be able to just click on "Run" and my code would execute similiarly speedy, as opposed to Debug where it would take 10 minutes to complete.

Now, however, clicking "run" behaves just like debug mode.... I don't want this overhead, how do I get eclipse to stop sending my app to the debugger already? I have searched online and found a couple people with the same issue, but simply rebooting my phone doesn't fix it, and there have been no other solutions posted that I have found.

Android :: Eclipse Error On Build.xml Target Debug / Release Does Not Exist

Oct 16, 2010

This is more of an Eclipse error than an Android or Ant error. My Eclipse project won't build because when it sees the build.xml created from the Android command, it starts looking for the debug and release commands. Well, since they are dynamically generated from the <setup> task, they don't exist. So now Eclipse (Build id: 20100218-1602) locking the project from build/run based on these errors. kay.. so here is the weird part: It worked this morning. In fact it has been working for weeks with the build.xml file sitting there. All I did was edit the build.xml file in Eclipse (changed some constants). Ant thinks everything is peachy.

Android :: How To Reach The Sub Activity Code In Debug Mode

Jul 25, 2010

I have a activity B that is called by activity A, I want to debug the code in B. I have set the breakpoint, however the debug control never enters B.

CODE:................

When I debug in eclipse, although the class B is called from class A, the debbugger pointer never enters the new window, where I have placed a debug point in Class B. I am not able to take the pointer control to class B and stop at a specific point, which will help me verify certain variable values.

Cannot Open Selected VM Debug Port On Eclipse Debian X64

Oct 29, 2012

i install new version of eclipse and Android sdk , but when i run an android project i get this error

Code:

Could not open Selected VM debug port (8700). Make sure you do not have another instance of DDMS or of the eclipse plugin running. If it's being used by something else, choose a new port number in the preferences.
ADB server didn't ACK
* failed to start daemon *
i try to solve the problem by following this , but i still get the same problem:

Code:

-Window -> Preferences -> Android -> DDMS
-Set Base local debugger port to "8601"
- Check the box that says "Use ADBHOST" and the value should be "127.0.0.1"

i am also tryng to reinstall android pluing for ecipse and even the android sdk , but i still get the same problem!

OS : debian6 x64bit
IDE : eclipse juno

Android :: Can Use TraceView In Native Code When Using NDK

Dec 10, 2009

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?
