Eclipse Android Development Error executing aapt: Cannot run program “/path/to/aapt”: error=2, No such file or directory: error=2, No such file or directory

Posted on March 24, 2014March 28, 2021 by rchapin

Even though the ADT bundle provides a 64 bit version, the system requirements indicate that “64-bit distributions must be capable of running 32-bit applications.” I failed to see that when installing it under Fedora Core 20 and was getting the following error from Eclipse:

Error executing aapt: Cannot run program "/home/rchapin/sdks/adt-bundle-linux-x86_64-20131030/sdk/build-tools/android-4.4/aapt": error=2, No such file or directory: error=2, No such file or directory  android_sdk    line 1   Android ADT Problem

I checked to see if the file was there. Yep. I → Continue reading “Eclipse Android Development Error executing aapt: Cannot run program “/path/to/aapt”: error=2, No such file or directory: error=2, No such file or directory”

Setting up Android in Eclipse, Unable to resolve target ‘android-18’

Posted on March 24, 2014March 28, 2021 by rchapin

When setting up Eclipse for Android development, after you have installed the Develeper Tools and NDK Plugins and linked to the ADT-bundle and then imported your project (see othere posts related by searching for ‘android’) I got the following error:

[2014-03-24 14:14:53 - android_sdk] Unable to resolve target 'android-18'

I went and checked to make sure that the Platform.MinPlatformToolsRev property in the ~/path/to/adt-bundle-linux-x86_64-20131030/sdk/tools/source.properties matched that of my project.properties file.

They were both 18. Eh? Why the error?

So, in Eclipse, → Continue reading “Setting up Android in Eclipse, Unable to resolve target ‘android-18’”

Invalid Project Description, project path overlaps the location of another project with the same name When Importing Existing Android Project in Eclipse

Posted on March 24, 2014March 31, 2021 by rchapin

I’ve got a new install of Eclipse and am setting up to do some Android development.

After getting the Develeper Tools and NDK Plugins installed and linking to the ADT-bundle that I downloaded, I was getting an error when attempting to import the existing project by going to File > Import > Android > Existing Android Code Into Workspace.

The error was:

Invalid project description /some/path/to/project/dir_name overlaps the location of another project: dir_name

Restarting XServer in Fedora 20

Posted on March 24, 2014March 31, 2021 by rchapin

I was having problems logging in this morning to my laptop. When I entered my password, it just hung. I pressed Ctrl-f2 to switch to an alternate tty, logged in as root and checked for errors in /var/log/messages.

Not seeing anything, I figured, I’d try and restart the Xserver. Still not being completely familiar with the sysctl paradigm it wasn’t obvious how to restart it.

So, as root, I simply switched the runlevel to 3, and then back to 5 → Continue reading “Restarting XServer in Fedora 20”

s3cmd ‘ERROR: Test failed: 403 (AccessDenied): Access Denied’ and ‘ERROR: Config: verbosity level ’20’ is not valid’ [SOLVED]

Posted on March 19, 2014November 25, 2021 by rchapin

I’m working on a project that includes sending data via Amazon Simple Storage Service (S3) and was having some problems configuring and using the s3cmd client.

The first thing I discovered about s3cmd is not to trust what it tells you when invoking s3cmd –configure to get things set up to use the bucket.

$ s3cmd -v --configure s3://some-bucket/some-prefix/

Clone and Backup a Bootable USB Drive

Posted on March 9, 2014November 25, 2021 by rchapin

We recently got a new ASUS laptop for the boys to use (I’ll use it too, it’s pretty sweet) which came with Windows 8.

It did not come with the install CD or license key, but included a recovery partition and the key in the BIOS. Now that we’ve had it for a few weeks and verified that all of the hardware works, we are going to put Ubuntu on it, but I wanted to make sure that I would → Continue reading “Clone and Backup a Bootable USB Drive”

Eclipse Crashing with SIGSEGV, Problematic Frame libgdk and/or libsoup Problem Solved

Posted on January 31, 2014November 25, 2021 by rchapin

I’m setting up a new workstation under Fedora Core 20 and getting my dev environment set up.

I had copied over my /opt dir from my old machine which included an older version of Eclipse (3.8.2) that I had been using. That version wasn’t behaving very well and I decided to go with the latest and greatest stable version (Kepler, 4.3.1).

Unfortunately, Kepler was dumping core with the following error:

A fatal error has been detected by the Java Runtime → Continue reading “Eclipse Crashing with SIGSEGV, Problematic Frame libgdk and/or libsoup Problem Solved”

Excellent Example and Explanation on How to Inject Properties from an External Properties File from Outside of a WAR in a Spring Application

Posted on January 29, 2014November 25, 2021 by rchapin

I am doing some refactoring on a Spring MVC application, pulling out configuration data and login crentials from the spring.xml file.

What I want to do is to consolodate sensitive data into external .properties files that can be read, at runtime by the app and not require recompiling the war to make changes.

Thanks to Ben Northrop and Summa Technologies for such a clear, concise and well written article.
