Android :: Debugging Java And C/c++

Feb 20, 2009

I can debug the Android Java code using eclipse and using the Remote Java Application debug configuration. This does not step into C/C++ code however as expected. I understand I have to attach the gdbserver to do this. Can someone provide a step by step tutorial on how to debug the native code of Android?Is there a eclipse plugin that makes this easier?

Android :: Debugging Integrated Java And Native Code

Feb 7, 2009

I am trying to figure out what is the best way to debug a mix of Java and native code? Please notice, that I am NOT trying to develop a native app. The app will be written entirely in Java, using Android SDK. However, I noticed that some pieces of the SDK use native methods (e.g. AssetManager, WebKit, etc). I wonder which tools Google developers use if/when they need to debug a mix of Java and C/C++ code? Eclipse/gdb or there are commercial tools which make the debugging experience less painful?

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 :: Java Compatibility With GetFields Method In Android Java.lang.Class

Feb 11, 2009

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....
}

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.

For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}


9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Android :: New SDK Causes Slow Debugging On N1

Sep 20, 2010

I've got a Nexus One running a debug version of my application, and I just today downloaded and installed the 0.9.8 version of the SDK tools, and I swear that Debugging latency has increased incredibly. I never bothered to measure the overhead before the upgrade because I always found the phone's debugging overhead to be small enough to not affect matter. Well, now I have AI code which runs at ~10 MS standalone taking 300-400MS through debugging. A 40X performance loss is not something to cough at. Is it just me not seeing the performance loss previously, or has something broken?

Android :: Debugging Just Apk File

I am not sure how is this possible?But we would like to debug the apk files without having the source code (source code lies with developers).But if something breaks I would like to report it to the developers. We would like to report the crash logs and the normal info about the app.

Android :: Can't Stop Debugging

May 18, 2010

I have an app which, for the last 12 hours or so, I can't NOT launch in debug mode on my handset. No matter what I do, it shows the "Process ... is waiting for the debugger to attach" dialog, and the process appears with the little green bug icon in DDMS. Never seen anything like it.Here's what I've tried: - Using the "Run" command, not "Debug", from Eclipse (duh) - Rebooting all hardware - Doing a clean install on the handset - Setting android:debuggable="false" in the manifest.That last one's freaking me out. If I can't turn off debugging for a production build, I can't distribute the app. And it's currently my top earner in the Market.Anybody got any ideas? About the only other thing I can think to try is a clean reinstall of Eclipse and the SDK, but that's enough of a PITA that I'm hoping I don't need to go that route.

Android :: Debugging With Different Keystore

Jan 29, 2010

I know that, to be able to sign a package with your own keystore, you have to use the export from eclipse. However, its not easy to keep doing this when you're still debugging the application. Since i have external libraries that uses another keystore and use the shareUserId, it would be reasonable to let, in eclipse plugin, you debug an application using any keystore.Any tips of how to make debugging easy with a private keystore?

Android :: Debugging On Mobile

Dec 24, 2009

I have tried to debug in my device (HTC Hero) that has android 1.5 (I think, and even I don't know how to update) and well.I have right checked the debugging option on the mobile adjustments of apps. So when I click on run, it goes fine but when I click on debug (all of this in eclipse) it does the same actions that it does in the run option. So I cant see it step by step.

Android :: Debugging With Eclipse On HTC Evo

Oct 16, 2010

I've turned on USB debugging.I have the latest HTC Sync and android SDK components.I'm using Eclipse 3.5 on windows XP. I'm running Android 2.2, and am asking for 2.1 as the minimum in the debugger.I work in Eclipse/Java just about every day, and have for several years.I'm even writing an Eclipse plugin at work as I type this neither Eclipse nor Java are new to me by quite a stretch.When I start a debug session for the "Skeleton App" sample project, I can see my Evo, and the activity launches (with any freshly saved changes), should I select it.I have tried different android connection types (charge only, disk drive, HTC Sync, and USB tethering) to no avail. I've tried Eclipse 3.6 for a bit before yielding to the inevitable and reinstalling 3.5. I monkeyed with the emulator for a while but ran into a different set of issues (I had to reboot the emulator every time I wanted to make a change... Eclipse's auto-build/hot-swap has me spoiled).Is there something I can add to (or remove from) the AndroidManifest.XML to deal with this? A magical incantation perhaps? Must I pray towards San Jose three times a day on a rug woven from kernel gurus' vast and scruffy beards? Is my Evo not Kosher? Must I be "sky clad" while debugging? Shall I teach my laptop to genuflect?

Oct 27, 2010

I want to run and debug my Android apps on my HTC Incredible.Connect your Android-powered device to your computer's USB port.

Nor is it already connected if I go to my SDK tools directory and do "adb devices" it returns blank.So what do I have to do to debug on my phone?

Android :: Run Without Debugging In Eclipse

Nov 29, 2009

When I run my app on my phone from eclipse, it always runs in debug. This has only recently started to happen. I guess I must have inadvertently changed a preference or something, but can't work out what. Does anyone know how I can switch it back so I can run without debugging?

Android :: Low Level Debugging ?

May 15, 2010

Is there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower? For example show what functions are being called from the libcore folder. I am also interested to find how it communicates with the linux kernel at the bottom of the layers. Is there a way to do this?

Android :: Better JavaScript Debugging For WebView

Mar 4, 2009

I'm debugging a Javascript+HTML app. All the content is in ./assets.

The app works fine in Firefox, Safari and iPhone (over the web).

But in the WebView, I only get: D/WebCore (626): Console: undefined line: 0 source: undefined

I need to debug this code. Could I either: - enable more debugging in the WebView? though I think this needs to be done in the framework. or: - set up a desktop WebView equivalent where I can run a Javascript debugging tool?

Android :: Debugging On Real Device

Sep 17, 2010

I have gotten to to the point where I need to test my application on a real Android device. I have obtained an Motorola Droid phone and attached it to my computer (Windows).I have installed the USB driver, and I believe that my computer can see the phone. When I start up the DDMS it shows my device as 'Online'. I cannot, however, figure out how to get the debugger to use the device instead of the emulator. The Android documentation states that when I run my program from within Eclipse that I should be presented with a 'Device Chooser', but that does not happen. I read somewhere else that pressing F11 will bring up the Device Chooser, but it only runs the application on the emulator. I know there is probably something obvious that I am missing here, but I cannot figure out what it is.

Android :: Debugging With Logcat And Emulator?

Apr 5, 2010

This is pretty simple: I'm using NetBeans on Linux with Android emulator 1.6. I have Logcat on my android phone, but the process of getting the messages to somewhere readable isn't smooth at all. Can someone tell me how to get Logcat running on the emulator? Is there anything I can do to see debug messages other then having to copy the apk to my phone and testing it?

Android :: Debugging Geo Locations Services

Jan 20, 2009

I wrote some reverse geocoding, geolocation and proximity alert routines for my little Android app. I took my Android out with me when running errands to test my routines; they're kinda hard to test from my couch. Half of them didn't work. What's the best way to debug something like this? Sprinkle a bunch of printf statements (or whatever you call them in Java) throughout the app? Log everything to the sdcard? Write a toggleable view (is that even possible?) that acts as a console? Faber Fedor Cloud Computing New Jersey http://cloudcomputingnj.com
