The problem is that it has different versions of jre

I have java 6 and 8 both installed on my system, so I uninstalled java 6 and set the path only for java 8.

But do not forget to restart the system after installing the paths.

Please pay attention to this Android icon at the top of the screen.

Android icon

This icon is at the top of this screen:

Screen which displays the API version to render the code

It probably displays number 20. It is a choice to use API 20 to render the window. Change it to 19 or 20W (not 20L). This will fix the problem.

API 19 selected

You may also need to reconfigure eclipse to run on Java 7. Runtime.

Add this to the top of eclipse.ini

 -vm C:/Program Files/Java/jre7/bin

For those who have the same problem: You do not need unistall Java 6. All you have to do is install it correctly on Eclipse.

  • First I have JDK fot Java 8 (aka Java 1.8): http://www.oracle.com/technetwork/java/javase/downloads/index.html
  • Install it as usual.
  • Go to Eclipse Settings and in Java -> Installed JREs
  • "Add ..." → Standard virtual machine → Next and find the installation path (on a Mac it will be something like: /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home).
  • Enter a good name, such as "Java JDK 1.8" and "Finish"
  • Be sure to mark the new JRE as shown. enter image description here
  • Restart Eclipse for the change to take effect.

This seems to be the problem ... "Automatically choose the best", selects version "L" of API 20 instead of API version 4.x of API 20. In my example, I am targeting API 19 and seemingly incompatible with choosing "API 20: Android L (Preview) ".

Sorry, this system will not allow me to send images yet ...

You can see the following note at https://developer.android.com/preview/setup-sdk.html

Note. The Eclipse ADT plugin requires Java 7 if your compilation is aimed at previewing the L project.

Perhaps you do not have Java 7?

Check out the JDK version. It should be JDK1.7. JDK 1.6 does not work.

OPEN SDK Manager -> Uninstall Android L (preview API 20, L), use this if you want to quickly fix this error.

What I did after updating java is to set the variable system for java again

Additional system parameters → Advanced → Environment variables.

I updated JAVA_HOME with this directory

C: \ Program Files \ Java \ jdk1.7.0_60

Back in eclipse, you can:

Click Properties → Android → Project Build Object

Change android L to android 4.4

If you want to use android L, then change the minSdkVersion manifest to "L"

In my case, my current version of java is 1.6.

So, I ran the command "update-alternatives --config java" to change the version to java 1.7 and then restart Eclipse, the problem is fixed.

Note. I installed muti-java version (Java 1.6 and java 1.7)

Hope to help you.
