LeJOSDroid crashed in Droid phone

[ray80127]

Hi,
I am learning how to control NXT by android phone recently.
My phone is HTC sensation 4g with version 4.0 .
My leJOS version is 0.9.1beta-2.

I have a similar problem as this post: http://lejos.sourceforge.net/forum/viewtopic.php?f=7&t=3035&p=15004&hilit=lejosdroid#p15004
My phone has paired to my NXT.
When I run the app, I can see the main menu (TachoCount, BTSend and RCNavigator)
As I touch the button of TachoCount or BTSend, the app crashed.
And also the message shows under the menu : "nxj.cache file not written as cache already exists. Choose one!"

However when I run the other program "MINDdroid", the app runs with no trouble.
I really want to solve this problem...
Can anyone help me?
Thanks for any opinion.

This is the log showed on eclipse when I touch the "BTSend" button :

I got around the service discovery problem by modifying ConnectThread in NXTCommAndroid in a way similar to this post on Stack Overflow http://stackoverflow.com/questions/3397 ... on-android . I still cannot get the sample projects to work properly, there seems to be a problem with connecting to the NXT similar to this post http://stackoverflow.com/questions/2268 ... perability . What MINDroid app are you successfully running?

EDIT: Sorry about the confusion with MINDroid. I got BTSend to work using the edits i mentioned above. The problem seemed to be that my phone was not automatically displaying a message for me to enter the bluetooth pin, I needed to pull down the menu from the top myself. Hope this helps!

Hi
the MindDroid app is the app that LEGO developed for android phone.
You can download it in the Google Play.
