    <p>I'm new here and I hope I could get some help with an Android App using Pocketsphinx (with NDK).</p> <p>I am doing this work for a school projekt where we are making a GPS and we wanted to add some offline voice recognition, Pocketsphinx seems to be the way to go so I downloaded the libraris sphinxbase and pocketsphinx as well as the demoproject they have. </p> <p>After quiet a lot of fixing and trying (first of installing and getting used to Ubuntu, fixing errors I got when trying to compile the libraries, errors from trying to build the libraries with the NDK to get the .so file, problems with the project not having right libraries for Android and transforming it to a 2.1 project to test on my phone) I was able to get the program to run(though for some reason I have to lanch it 2 ro 3 times before it shows up on my phone).</p> <p>My problem appears when I try to use the demo project, for those that don't know how it looks it's just a simple text area and a button, you press the button so it starts recording and then you speak and the inputed speech should appear as text in the area, as soon as I click this button it closes. It doesn't crash, the process dies but I don't get a stacktrace. From what I can see from the debug information it starts the recording process but then crashes after this, my guess is it crashes once it is about to start doing the work with the native code.</p> <p>What I can understand from the unclear debug information I get is that the Native enviroment is being closed, I get a message from the debug with the tag Zygote and the message being "Process X terminated by signal(11)". From my searching I have learnt that this most likely means a segmentation fault (SIGSEGV). </p> <p>This is as far as I have gotten, I have no real understanding of what segmentation fault means or how to resolve this problem. Below I'll add a part of the log, this is what I see before the program dies, if you need anymore information from the logs plese tell me what and how to get it as I am very unsure what information will be helpful. </p> <p>I am working on Ubuntu 11.10 with Eclipse and the Android pluggins, my phone is a Sony Ericsson Xperia if that's relevant, running some Sony Ericsson version of Android 2.1, the sphinx libraries are the latest version from the Sphinx projects website. </p> <p>Hope someone here can give me some way to keep working on this, I am mostly a Java developer but I have done some work in C++ so if I have to I'll dig into the C code as well but I hope it won't go that far.</p> <p>Here is the log extract:</p> <pre><code>03-20 11:37:22.676: D/edu.cmu.pocketsphinx.demo.RecognizerTask(385): signalling START 03-20 11:37:22.676: D/edu.cmu.pocketsphinx.demo.RecognizerTask(385): signalled START 03-20 11:37:22.676: D/edu.cmu.pocketsphinx.demo.RecognizerTask(385): gotSTART 03-20 11:37:22.676: D/edu.cmu.pocketsphinx.demo.RecognizerTask(385): START 03-20 11:37:22.806: D/edu.cmu.pocketsphinx.demo.PocketSphinxDemo(385): Showing Dialog 03-20 11:37:22.826: I/AudioHardwareQSD(1066): AudioHardware PCM record is going to standby. 03-20 11:37:22.836: I/AudioHardwareQSD(1066): AudioHardware PCM record is going to standby. 03-20 11:37:22.836: D/dalvikvm(385): +++ not scanning '/system/lib/libwebcore.so' for 'Decoder_startUtt__SWIG_0' (wrong CL) 03-20 11:37:22.836: D/dalvikvm(385): +++ not scanning '/system/lib/libexif.so' for 'Decoder_startUtt__SWIG_0' (wrong CL) 03-20 11:37:22.846: I/DEBUG(1063): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** 03-20 11:37:22.846: I/DEBUG(1063): Build fingerprint: 'SEMC/X10i_1234-9753/X10i/es209ra:2.1-update1/2.1.A.0.435/TP7d:user/release-keys' 03-20 11:37:22.846: I/DEBUG(1063): pid: 385, tid: 395 &gt;&gt;&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
