Importing Errors in eclipse

gen already exists but is not a source folder:-

I get the same problem.

Two actions, first:

1.Right click on the project and go to "Properties"
2.Select "Java Build Path" on the left
3.Open "Source" tab
4.Click "Add Folder..." and check "gen" and "src"


second: (because the previous action asked me to remove something... I do not remember what it was...)

1. Right click on the project and go to "Properties"
2. Select "Java Build Path" on the left
3. Open Libraries "tab"
4. Add an external JAR. Add the Google API that is in your android directory (android-sdk\platforms\android-yourversion
And now it works for me!

How to fix gc overhead limit exceeded eclipse

Eclipse will throw GC overhead limit exceeded error when it runs out of memory, normally while performing memory-consuming operations such as building workspace on big projects.

The error would look something like this;

An internal error occurred during: "Building workspace".
GC overhead limit exceeded


To fix this problem, you'll need to allocate more memory to your Eclipse instance. To do this, locate the eclipse.ini file in your Eclipse's installation directory. The content would be something similar to the following;

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20140116-2212
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=256m
-Xms40m
-Xmx512m


To increase the memory allocation for your Eclipse instance, edit the number in the following lines accordingly.

-Xms512m
-Xmx1024m

These options are passed to Java when launching Eclipse. Xms specifies the initial memory allocation pool, and Xmx specifies maximum memory allocation pool for Java Virtual Machine (JVM). The number is the amount of memory, in Megabytes.
