Unable to execute dex: Multiple dex files define & java.lang.NoClassDefFoundError

Question

I am between 2 errors. I dont know what to do. 1st error:

[2014-07-04 15:07:01 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;

[2014-07-04 15:07:01 - MyGov] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

As suggested here, unchecked Android Private Libraries

I have added all libraries(from AndroidPrivateLibraries) into libs except support-v4-18.0.4.jar library(which is causing to before stated error).

SplashActivity(this activity opens, when application starts) is working fine. But when I tried to open MainActivity following error came out:

java.lang.NoClassDefFoundError: com.globalsolutions.mygov.ui.MainActivity

According to this solution, Android Private Libraries should be checked.

Conclusion:

error#1 makes me to uncheck Android Private libraries
error#2 makes me to re-check Android Private libraries

How to be in this situation? How to solve this problem? Thank you for your valuable time!

UPDATE:

Notification in console for error 1:

[2014-07-04 15:06:48 - MyGov] Dx trouble writing output: already prepared [2014-07-04 15:07:01 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper; [2014-07-04 15:07:01 - MyGov] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;

Answer 1

I am between 2 errors. I dont know what to do. 1st error:

This error is fairly self-explanatory. You are including 2+ JARs (or a JAR plus your own Java classes) that have duplicates as noted.

The solution is to determine where the duplicates are coming from (e.g., examining the JARs) and then figuring out which JAR to change or get rid of.

As suggested here, unchecked Android Private Libraries

I have downvoted that answer, as it is rather wrong.

I have added all libraries(from AndroidPrivateLibraries) into libs except support-v4-18.0.4.jar library(which is causing to before stated error).

I am interpreting that sentence to mean "when I add support-v4-18.0.4.jar, I start getting the build error". In that case, you know one of the two JARs that is the source of your problem. Given the class names in conflict, I would guess that the other one is libGoogleAnalyticsV2.jar. You need to either:

1. Find versions of these JARs that are designed to work together, or

2. Get rid of one of these JARs.
