Installing Pocketsphinx on Android

Question

Hi,

I have some questions on installing Pocketsphinx on and Android phone, and I haven't been able to find answers on CMUSphinx's support forum, IRC, existing StackOverflow posts, or intensive Googling. If anyone here has a minute and would be willing to help, I'd appreciate it.

First off, I'm confused as to whether I can even install Pocketsphinx on Android. I believe I need Java bins in order to run on Android, so I attempted to install Sphinx 4. To test the program, I made an empty activity and moved the HelloWorld demo file into the onCreate method.

Then, I added the following libraries to the build path:

• js.jar
• jsapi-1.0-base.jar
• junit-4.8.1.jar
• sphinx4.jar
• tags.jar
• WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar

The code deploys on a Droid 2 running Android 2.2, but I get the following error at runtime:

ERROR/AndroidRuntime(11567): Caused by: Property exception component:'wsjLoader' property:'location' - Can't locate resource:/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz

I am including that jar file in the build path, so I'm not sure why that's causing an exception to be thrown. But then again, I'm not even sure I should be trying to install Sphinx 4 on Android. Does anyone know what I should do? Thanks in advance for your help.

Hi, the error u got is because WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar must be extracted and the content must be put inside lib folder of ur project...

The error occurred because it is searching for a folder WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz inside lib. This folder is available inside the jar.

Even i am trying to use sphinx4 in android.. so if u succeed let me know...

I have also tried like this only. But the thing is for me now apk is itself not loading states "Installation error: INSTALL_FAILED_DEXOPT" error. (here in my code launcher activity creates a button, onclick of the button instance of helloworld would be created instead of main(), i am using constructor)

previously I did like having an activity in the oncreate method, the whole data in main() method of helloworld would be there. (here i wasnt able to even create the ConfigurationManager instance some problem while loading the helloworld.config.xml..........

Ur post seems to be like u were able to create those things and all.... could u share ur code? If possible or just the framework of where u have the .config.xml files and what all changes u had done in that...........

Thank u........
