Installing GenyMotion on your ubuntu 14

0

Android App
– Added exception handling and error checking for request and response
– Updated the Drive->Requirements->Detailed Requirements, added Section 13 for future exception handling rules
– Installed GenyMotion Freemium, added all 4.x devices

We can test the app on the virtualbox, we dont need to invest on devices, I thinkšŸ™‚

For installing GenyMotion
https://www.genymotion.com/download/
https://help.ubuntu.com/community/VirtualBox/Installation

Install the Emulators 4.4 (only)
After you load the emulator you will Google Play is not installed, for that the following links are useful.

ld: library not found for -l

To build as libary

Right Click->Properties->Build->Setting-Build Artifact->Dropdown to choose Shared/Static library

Difference between Shared / Static library

Now to include this library, copy the library to the project you want it and put it in a libs folder at the same level as the src level. Note, I am assuming that you have a src folder.

On thisĀ project Right Click->Properties->Build->Setting->Libraries->

  1. in the -l area add name of library without the prefix lib and without the suffix .so
  2. in the -L area add ../libs, remember its 2 dots since the current folder is src, not the root of the projectšŸ™‚ YEAH, I tried ./libs for 1 hours before trying out ../libs

 

Building our first C++ cuda library

So the first thing you do when you get CUDA ready is try your hands out on the sample code and NSight (the eclipse of CUDA). This goes smoothly, but as soon as you start writing cpp codeĀ for developing libraries, you can hit all kinds of issues. This post has fixes for those crazy issues that has no help on even StackOverflow.

  • Syntax Error :Ā For some reason I got a “Syntax Error” on the constructor and destructor lines of my CPP code. To fix this, rename your .cpp as .cu. And rename your .h as .cuh.
  • My enumsĀ PROCESSOR_CONFIG, would not resolve at Ā Timer::PROCESSOR_CONFIG::DEVICE. I had a similar issue to this. To fix this I had to compile using a C11 directive. I used this, to fix it. Refer to my answer (Siddharth).
  • Finally I had to add a main (I need to get rid of this expectation soon).

Getting Started with CUDA

0

Interesting and challenging as I would define it. So get ready for a ride. If you are a applications developer, switch off now. This is a system programmer post, and someone who enjoys toying with the command promptšŸ™‚.

To get started with CUDA, first thing you need is a 64bit OS. Without that CUDA wont work.

Once you have a 64 bit OS, goto developer.nvidia.com, and follow the instructions. DONT download the run file, download the dpkg file for the installation. The run file is stupid and useless. Takes for ever to run and gets no results. You may also end up screwing up your OS.

So I ran the following

sudo dpkg -i cuda-repo-ubuntu1504-7-5-local_7.5-18_amd64.deb
sudo apt-get update
sudo apt-get install cuda
sudo apt-get install nvidia-cuda-toolkit
sudo apt-get install cuda-drivers
sudo apt-get install nvidia-nsight
export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib:$LD_LIBRARY_PATH
cd /usr/local/cuda-7.5/
sh cuda-install-samples-7.5.sh /home/<username>/development
sudo apt-get install nvidia-352
cd /home/<username>/development/<cuda samples folder>/
make

To check your installation

If this displays an error than run

sudo apt-get purge $(dpkg -l | awk '$2~/nvidia/ {print $2}') sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt-get install cuda

Android Camera, does not return to onActivityResult and resets calling activity

0

What is surprising is that the documented way of making this shit work does not work.

http://developer.android.com/guide/topics/media/camera.html

Scroll to Image Capture Intent,

// photoIDFile is type File
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoIDFile)); // set the image file name

With this it just does not work. My Uri is correct, I have

file:///data/data/com.samagra.operatorapp/files/photo1441253398999.jpg

But this gets the camera to return.

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoIDFile).toString()); // set the image file name

Now the camera resets my activity and I loose my activity, it goes back SHAMELESSLY.

I had to read through the Camera documentation on android.developer.com and read Building a Camera App section. This worked well.

Dreaded Exception SEVERE: A message body writer for Java class, MIME media type application/json

0

Gone are the days when error messages made sense. Something as simple as Annotation Missing has been replaced by something silly as MIME media type application.

The crazy exception below translates to having the following annotations in the ConsolidationSearchForUsersResponse class

@XmlRootElement(name = "Response")
@XmlAccessorType(XmlAccessType.FIELD)
