• When should I decline to make a requested change?

  - by reuscam

  I work on the software side of a company that provides custom hardware with software running on top of it. Often times the hardware is not engineered well. In those cases, I am often asked first to troubleshoot the problem - of course the symptom is always "your software crashed" or something along those lines. Just recently we had another one of these incidents where power on a USB line is not reliable, and it causes a USB device to fail. This causes a usability problem in one of our applications. I have been asked by upper management to handle this better - continually monitor the USB device, and if it disappears, then reboot, or try to reset it. Doing either of these is not guaranteed to fix anything. Ultimately, the real fix is to correct the reliability of the device from the hardware side. I could improve performance, but not to 100%, and of course I would be using my already limited time to bloat code and add yet another device monitoring thread. So with all that said, how do I make a good decision about when to say that this needs to be a hardware fix, and only a hardware fix? Can I approach this quantitatively, and come up with some sort of definitive yes/no test? I'm sure its not that easy.

• "Android Create" call fails in windows 7 - missing JDK

  - by reuscam

  I'm having a problem getting my android dev environment setup in Windows 7. I follow the instructions here, as well as several environment sublinks. I am using Eclipse with the Android plugin. I have installed the Java JDK several times, in various locations (jdk-6u20-windows-i586.exe) - but I am obviously missing something. Every time I run "android create avd --target 2 --name my_avd" I get an error: C:\Users\andrew>android create avd --target 2 --name my_avd WARNING: Java not found in your path. Checking it it's installed in C:\Program Files\Java instead. ERROR: No suitable Java found. In order to properly use the Android Developer Tools, you need a suitable version of Java installed on your system. We recommend that you install the JDK version of JavaSE, available here: http://java.sun.com/javase/downloads/ You can find the complete Android SDK requirements here: http://developer.android.com/sdk/requirements.html This error message is the reason for me installing the JDK several times over. First I tried installing to a location on my e: drive. I then moved it to the default loc (program files (x86)\java\jdk.6.something. I also tried forcing it to go into the program files\ path, but it still automatically installs into the (x86) path. I have added the install path to my path environment variable every single time, yet I still continue to get this error. My suspicion is that windows 7 and the android tools are not playing together well in terms of finding the JDK, but who knows, it may be something entirely different. If you have seen this error before, I would appreciate a hint.

• Sharing code between Android and Windows Mobile

  - by reuscam

  I'm doing some initial research on smart phone development, and I noticed that Android and Windows Mobile both support c++ for application development. I was curious if anyone had any experience trying to manage shared files between both Android and Windows Mobile, and to what extent that code can be shared? e.g. no user interface can be shared, but web service and business logic classes can be shared, etc.
