java.lang.NoClassDefFoundError: Failed resolution of: Ljavax/naming/ldap/LdapName

I have implemented ProGuard to cut off unnecessary codes. But after the app starts, I am getting the following error -

What should I do now? Does it something to do with my library?

Android’s documentation for ProGuard describes it like so:
“The ProGuard tool shrinks, optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names. The result is a smaller sized .apk file that is more difficult to reverse engineer…. Having ProGuard run is completely optional, but highly recommended.”
Now adding proguard can cause problems if your app contain third party libraries, broadcast receivers, custom widgets etc.. so you need to add proguard rules to add this classes in runtime otherwise the classes will not compile in APK version and you will get errors
For details about proguard and it's usage see this link:http://omgitsmgp.com/2013/09/09/a-conservative-guide-to-proguard-for-android/
there is a standard proguard rules form which you can use:
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
# Obfuscation parameters:
#-dontobfuscate
-useuniqueclassmembernames
-keepattributes SourceFile,LineNumberTable

Please let me know, what am I doing wrong, and how to fix.

Adding this in proguard-rules.pro worked for me.
-keep class twitter4j.** { *; }

Yes I accept the above (NarendraJi) answer. But in my case, it was not showing which library or class creating the issue.
It is showing like
Caused by: java.lang.NoSuchMethodException: <init>
at com.a.f
From the above information we cannot understand the problem. So I used the "app/build/outputs/release/mapping.txt" file.
mapping.txt file having clear information about all classes,methods and packages. So we can easily solve this type of problems

Proguard and mixpanel issue

Add this to your proguard config:
-dontwarn com.mixpanel.**

How to make org.apache.http.legacy work with ProGuard (azure mobile services)?

The problem:
I'm using android mobile services, which relies on androidhttpclient.
Referencing org.apache.http.legacy resolves all the problems and the app runs just fine. However, with proguard on, I keep running into issues.
The problem plays out in two scenarios. If I keep the export checkbox checked (in jave build path), I get a 'Stub!' exception as expected (see discussion below)(see screenshot for which checkbox I'm talking about)
The runtime crash of type: "Stub!":
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.stuffd/com.stuffd.MainActivity}: java.lang.RuntimeException: Stub!

If however, I keep the checkbox unchecked (as suggested - see discussion below), I get and AbstractMethodError exception.

proguard config used:
-dontwarn org.apache.http.**
-dontwarn android.net.http.**
-dontwarn com.microsoft.windowsazure.mobileservices.**
Has anyone else run into this and has figured it out?

Here's what I am using, allowing the OS to properly replace the stubbed methods at runtime.
-keep class org.apache.http.** { *; }
-keep class org.apache.commons.codec.** { *; }
-keep class org.apache.commons.logging.** { *; }
-keep class android.net.compatibility.** { *; }
-keep class android.net.http.** { *; }
-dontwarn org.apache.http.**
-dontwarn android.webkit.**
It's all the stubbed packages provided by org.apache.http.legacy.jar.

You're right not exporting the legacy apache lib. However it has to be located outside the libs folder and added to the Build Path (when using Eclipse). Otherwise it gets exported anyway with your Android Private Libraries.
I'm using GMS, Volley and AndroidHttpClient in my own communication classes.
Here's what I had to add to the proguard settings:
-dontwarn org.apache.http.**
-dontwarn com.google.android.gms.**
-dontwarn com.android.volley.toolbox.**
-dontwarn com.myapp.communication.**
-keep class com.google.android.gms.** { *; }

When using Proguard, do you need a separate config for each referenced library?

My application has references to HoloEverywhere and SherlockActionBar, both which are in-workspace projects. When I enabled Proguard for the application only, it crashes giving these errors:
11-15 11:50:11.090: E/AndroidRuntime(24823): Caused by: java.lang.RuntimeException: java.lang.NoSuchMethodException: <init> [class android.app.Activity, int]
11-15 11:50:11.090: E/AndroidRuntime(24823): at com.actionbarsherlock.a.a(Unknown Source)
11-15 11:50:11.090: E/AndroidRuntime(24823): at org.holoeverywhere.a.a.l(Unknown Source)
11-15 11:50:11.090: E/AndroidRuntime(24823): at org.holoeverywhere.a.a.setContentView(Unknown Source)
Is this because I only enabled Proguard for the app and not the other in-workspace projects HE and ABS?
I am using the default proguard-project.txt in the sdk and did not add any additional rules.

No you do not.
Use these rules to keep the referenced classes un-obfuscated.
-keep class com.actionbarsherlock.** {*;}
-keep class org.holoeverywhere.** {*;}

this also will help
