Android :: How To Understand The Cause Of Exception Having Stacktrace

Aug 24, 2010

We have written an Android application which sends stack traces to our server, if any occur. Sometimes we get weird stack traces that seem not to be an exception from our application.

For example:


CODE:........

There is no mention of our own classes, only Android's standard classes. It's obvious that this exception takes place when scrolling of item list (ListView) occurs, but I can't even uderstand how I can fix this bug. I can't reproduce this bug.

Android :: Google Create Instuctions That Windows Users Understand. Googles Instructionsfor - NDK Install

Apr 6, 2010

Below are the only instructions i managed to find from google on how to install the android NDK, it is written as if we all run Linux and presumes we all understand what these obscure tools are. My comments and questions appear in Italics if somone who knows unix and windows would translate for google that would be great!

Android NDK Installation

Introduction:

Please read docs/OVERVIEW.TXT to understand what the Android NDK is and is not. This file gives instructions on how to properly setup your NDK.

I. Requirements:

The Android NDK currently requires a Linux, OS X or Windows host operating system. Windows users will need to install Cygwin (http://www.cygwin.com) to use it. Note that running the NDK under MSys is not supported.

You will need to have the Android SDK and its dependencies installed. The NDK cannot generate final application packages (.apk files), only the shared library files that can go into them.

IMPORTANT:
The Android NDK can only be used to target system images using the Cupcake (1.5) or later releases of the platform. This is due to subtle toolchain and ABI related changed that make it incompatible with 1.0 and 1.1 system images.

The NDK requires GNU Make 3.81 or later being available on your development system. Earlier versions of GNU Make might work but have not been tested.

You can check this by running 'make -v' from the command-line. The output should look like:

GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc.
...

On certain systems, GNU Make might be available through a different command like 'gmake' or 'gnumake'. For these systems, replace 'make' by the appropriate command when invoking the NDK build system as described in the documentation.

Great some strange thing called gnu make.. if your not going to tell me what it does maybe you then at least you could give me a URL to it?

The NDK also requires a Nawk or GNU Awk executable being available on your development system. Note that the original 'awk' program doesn't implement the 'match' and 'substr' functions used by the NDK build system.

Ok another tool, with 1 of 2 possible names, but not the third... and again where should i download this?

On Windows, you will need to install a recent release of Cygwin to use the NDK.
See http://www.cygwin.com for instructions.

Woohoo a URL! download took about a day because these install instructions do not specify what parts to download.

II. Preparing your installation prebuilt cross-toolchain binaries:

After installing and unarchiving the NDK, you will need to run the following
command from the root folder:

build/host-setup.sh

hello? windows dont run nothing but .exe .com or .dll, just tell me how you want me to run it..

This will test your setup and make sure the NDK can work properly.

Nothing is said about where any of these things need to be installed to (what directory)

Motorola Droid :: Android Can't Understand Wife's Name / "train" It To Associate Certain Spoken Word With That Result?

Aug 12, 2010

My wife's name is Marilyn. Not Maryland. No, I don't want to send a text to the state of Maryland. Or call the state. :0)

Is there a way to "train" Android to associate a certain spoken word with a certain result?

Oh, and it can't get "U2" or "REM" right either! I have been messing around with the new voice commands (after downloading the app and widget replacement), and I figured these would be popular enough (although oddly spelled) to be configured in. It got the Beatles, though!

Android :: Out Of Memory Exception

Sep 2, 2010

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:

Android :: Unexpected End Of Document Exception

Nov 21, 2010

I'm getting a "SAXParseException: Unexpected end of document" error when trying to parse an xml document on android. The document in question is from the google weather api, but it seems to throw the same error regardless of the xml file in question (as long as the xml is valid) so I suspect it's a problem with my approach, rather than the xml. This is being done as a learning exercise, so I've probably (hopefully) overlooked something obvious. I've run the xml through an online validator, and it comes back as being well formed. (Can't tell me if it's valid as I don't have a DTD, but I dont think I need the DTD to parse the xml). This is the code that I'm using to try and parse the file:

private void refreshForecast() URL url;
try { url = new URL( "http://192.168.1.66:8000/google4.xml");
URLConnection connection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream in = httpConnection.getInputStream();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
// falls over here parsing the xml.Document dom = db.parse(in);
} } catch (ManyExceptions e) { ....
} A cutdown version of the xml that produces the error is:

<?xml version="1.0"?>
<xml_api_reply version="1">
<weather>
<forecast_information>
<city>Hamilton</city>
</forecast_information>
</weather>
</xml_api_reply>

The stacktrace is:

11-20 06:17:24.486: WARN/ROGER(406): org.xml.sax.SAXParseException: Unexpected end of document

In the interest of brevity, I've not included the original xml, but it's just the standard weather xml from googles feed. I've also tried a few completely different xml files, (including the sample from http://www.ibm.com/developerworks/xml/library/x-android/) and they all give the same error. (They also all validate as well formed when I run them through an online xml validator). This makes me think that it's not a problem with the xml, but rather with how I'm trying to feed it into the parser.

Android :: XML - RPC Interfaces / Exception On Permissions

Mar 4, 2010

I have some well-debugged XML-RPC interfaces on a site that work wonderfully from both PHP and from JAVA. Using Eclipse I am able to write Java apps using either the Redstone or Apache XML-RPC libraries quite simply. These test cases using the 2 libraries utilize JavaSE-1.6 (jre6) libraries as well as one of the 2 xml-rpc libs referenced above.

My problem is making this work on Android. I have added ADT to my Eclipse setup and easily executed the HelloWorld test using a virtual 1.6 or 2.1 Android device - no problems. Whenever I go into the Build Path in Eclipse and add the external jars for either the apache or redstone XML-RPC libs my console goes wacky with a ton of the following:
Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

If I push ahead and debug the code when it actually ships off the XML request I get an exception out of the XML library on permissions of some sort. Why does this only happen in an "Android" project. These libraries seem to have no problem running in Non-Android standard java configs. Once we proof the ability to talk to our server we can proceed down the road of actually porting our app to Android.

Android :: Grabbing System Exception

Sep 30, 2009

i'm andrea from androidiani.com, i'm working on a library that will help developers about managing unexpected exceptions. The library is quite simple on it's idea, but i can't grab the unexpected exception withouth the use of a "global" try catch clausole. I saw the instrumentation class but i think it can't be useful for me..
Obviously the library will be free and the webservice too.. ( unless for the applications that generates quite low traffic ) But i personally don't love the way of global try catch..
