Android :: How Can I Debug Hardware Dependent App Without Access To Hardware?

Aug 18, 2010

I have an open-source application on the Android market. It seems to work fine for me (with over 1,000 active installs, I have to presume that it works for most people).I recently got a bug report that indicated a problem for at least three users on Samsung phones (Intercept and Captivate). I have been unable to reproduce the problem on my ADP2 and on the emulator.In order to get enough data to diagnose the problem, I first tried to add logging and then I asked users to submit logs via Log Collector. Each time a user tried to send the log (there were four attempts), it was truncated and I did not get any useful data.I then added ACRA to the project in an attempt to get information, but I don't seem to be able to automatically detect the bug in order to send a report.Since I don't have a Samsung phone and I can't reproduce it on anything where I could connect with the debugger, I am mostly out of ideas. The only idea I have left is to add a button to the UI to generate a report.Are there any other approaches to suggest?

Update: since people are asking for more specifics: essentially, the app reads in text files from the assets and puts them (with some preprocessing) into a TextView in a ScrollView. (The data is prgressively added to a SpannableStringBuffer and then that is passed to TextView's setText() function.) Depending on the options chosen, the text displayed is between 15k-115k. On phones with this issue, only part of the text is displayed. The cutoff point depends on the options, but seems to be somewhere between 17k-18k.

ACRA sends a report for all uncaught exceptions and puts them into a Google Form/Spreadsheet. I've gotten reports from my emulator and from my phone, so I know that end works. (Actually, I've often found it faster to debug from the stack trace in that report than to attach the debugger to the process.)Phone specs: I have exercised the app on emulators running 1.5, 1.6, 2.1, and 2.2. My phone is ADP2 (the developer version of the MyTouch), but I've installed a third-party ROM to jump up to Froyo (2.2). I am unaware of an emulator specifically for the Samsung OS build, although that would be quite helpful here.Since the expected text length is constant, I should be able to detect if it is read correctly or not. I added checks at the end of my text processing, but those never triggered, indicating that the problem was not with reading the file. I then tried adding checks to onPostCreate and onPostResume, but those did not fail either. It seems that the UI thread had not yet actually run at that point, though.I've now done 6 private APK versions attached to the bug in the bug tracker. I frankly am surprised that any users are still trying them. This latest version has a button to force a bug report - that will only be called after the UI thread has laid out the screen. Hopefully that will give me enough variable information to point me in the right direction.

Android :: Cannot Access The Internet While Debug On Device

Oct 5, 2010

I'm trying to develop an android application that uses network connection. The server is up and running, but when i am trying to access it from the device that runs the android app (in debug mode-using eclipse) it outputs a message that 'cannot find the server' after a UnknownHostException occurs! I have tested the server with a java application and it works fine! What is the problem then with the device?

Android :: Can't Use Dependent Projects In 1.5 / Fix This?

May 5, 2009

I have 2 projects in the following layout

MainActivityProject -> BaseProject

(i.e. MainActivityProject depends on the other project). Both are android projects created with the eclipse "New Android project functionality) however, the BaseProject does not have an activity defined. However, in BaseProject I define an activity base class where MainActivityProject's Activity derives from. This used to work fine up until 1.1 but now with the 1.5 SDK I get ClassNotFoundExceptions when launching the app.

Any suggestion on how to fix this? I obviously dont want to copy all the sources to a single project as I intend to reuse my Activity base class for other things (it contains some boiler plate stuff that I dont want to have in each and every activity.

Android : Way To Manage Orientation Dependent Activities?

Mar 11, 2010

I have two activities, one per orientation - PortraitActivity and LandscapeActivity. They are pretty much different, I can't use one Activity with different layouts. If user changed orientation I have to shutdown one of them and start another. What is the best way to manage them? Does it make sense to create GroupActivity? Or each Activity should check if the current orientation is what it needs? If so, is it save to start new Activity in onCreate method of previous one (which is not actually created yet)?

Android :: How To Consume Session Dependent WCF Services Using Ksoap2

Jun 23, 2010

I am using Ksoap2-Android for consuming the WCF Services.

For the dotnet client we keep the allowCookies="true" in our binding configuration and it sends the same sessionid and keeps my sessions intact in my WCF services (My services are
interdependent and use the sessions).

Any one know any such setting for ksoap2-android, that will allow me to consume the
WCF service keeping my session intact on the server.

Currently when i make a new call to the service, the sessionid gets changed and all my
session variables clear out and loose their values.

Android : Is Parcel's Data Size Platform Dependent?

Sep 27, 2010

According to the API doc, Android seems to support for changing the data size of Parcel container. And there is no notice limiting the size of Parcel. The document is here

On the other hand, when our developers are doing some tests on this, the size is dependent on the platform and devices.

So i just wonder whether there is any limit on the data size of Parcel. At least this information should be mentioned in the API document.

General :: 3G Frequency Of Phone Is Hardware Or Firmware Dependent?

Dec 2, 2012

I am asking this because recently bought a BLU VIVO D910a phone from U.S., it has Android 4.0 firmware and its 3G Network is HSDPA 850 / 1900.

I made a big mistake, because the country where I currently live and work (Montenegro) uses 2100 3G network. I shoud have ordered the international version of BLU Vivo, the D910i which has HSDPA 850 / 2100. So, currently I cannot make use of the 3G data capability of my new phone

My question is: if I get the firmware (or just the modem.bin) of D910i and flash it to my phone will I change by this way the 3G frequency or it is hardware-dependent?

Android :: Multiple Dependent Android Projects In Eclipse

Jun 14, 2010

I just started to play with android dev and java+eclipse is pretty new to me. I managed to create simple project and run it on my device. Now I want to create simple game (more of them actually) and I would love to use shared code base for all of them (game loop, initialization, etc..). Problem is that I have no idea how to correctly do this. I created android project called engine with all basic stuff that I need and made it work on device. Now I tried to create another project in same workspace called mygame. Main class (activity) of mygame is MyGameApp which inherits from EngineApp (main activity of my engine project) which inherits from Activity. I added engine project into required projects in mygame build path tab in properties. Problem is that when I try to run this project it crashes on ClassNotFoundException trying to find my MyGameApp class.

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 :: How To Debug An App With GDBSERVER

Jan 13, 2010

I'm trying to debug a native shared library that my App uses through JNI. I can attach to a running app just fine with "gdbserver --attach pid" but i need to actually launch my app when i launch the gdbserver command.

There's a million blog hits on this topic but none of them seem to be clear as to how you launch your app. They all say to just type "gdbserver ./MyProgram" but what exactly is "MyProgram". Is that MyProgram.apk? Is it Is it some other file that gets created when the app is installed? If so, what's its path?

Android :: Trying To Get USB Debug To Work On Windows 7

Nov 17, 2010

I am using Windows 7 64bit and I am trying to get my computer to detect my HTC Desire, but it's not picking it up. I have everything available installed through the Android Updater and I have got my phone running through Ubuntu, so it is definitely a problem with Windows.

I am using Windows 7 64 bit. I have a HTC Desire running Stock 2.2 (Froyo) that works with USB Debugging on my Ubuntu machine. Windows does detect that my phone is plugged in. It shows as a mass storage device. I have all the available things installed via the Android Updater.

Android :: How To Debug App On Emulator Using NetBeans IDE?

Mar 3, 2010

I recently downloaded the latest NetBeans IDE (for MACOSX) and imported/migrated a project over from the ECLIPSE environment.Everything looks, and works well... except that EMULATOR gets stuck "waiting for the debugger to attach." I tried "Attaching Debugger." and set the PORT value to every case I've ever read about (8200, 8700, 5555, etc.) but the connection is refused.I am of the opinion that this is not the preferred way to start a debugging session in NetBeans for Android.

Android :: Can't Debug With Nexus One / What I Might Do Wrong?

May 22, 2010

I have a HTC Hero and newly also a Nexus One. I used to debug with the HTC Hero which worked just fine. Now when I try to debug with my Nexus One I just can't make it work. I updated everything Android via Eclipse and have now the version which officially supports Nexus One as a debug device. Whenever I connect the Nexus One, turn on Debug Mode and want to run the application I don't see the device in the debug list.

Anyone got any ideas what I might do wrong? As said above, with the HTC Hero it works just fine.

Android :: SDK Not Recognizing Debug-able Device

Jun 5, 2010

I'm new to Android development, and am attempting to run a test application on my actual device. I followed the instructions at (and related links), but the Android Debug Bridge (adb) doesn't recognize my connected device.

Some quick background info, I'm running WinXP, developing with Eclipse, with a Motorola Droid running Android 2.1 as my physical device.

An overview of the steps I've taken: Installed the Android SDK, downloading all necessary packages. Enabled USB Debugging on my device. Connected Device via USB, installing the driver from the SDK folder.

I'll stop here (though I continued to setup my application to be debug-able in Eclipse), because I at this point I noticed a problem.

Running "sdkoolsadb devices" at this point (at least, by my understanding), should list my device as connected. However, running this yields only: List of devices attached

My device recognizes that it's connected to a computer in debug mode, and my computer recognizes the device. However, I can't seem to get the sdk to recognize it. I'll leave out the steps I used to setup Eclipse for debugging on a device, as it doesn't seem relevant to the problem. I'll include them if requested.

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 2:


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?
