I am enabling proguard like this when I try to build apk in release mode I am getting error code 1 in eclipse Juno. if I use same code in android studio I can able to build release apk . if I reverse engineer the apk which got from android studio I can read the entire code so how I can obfuscate the code

to work with proguard you need to just enable proguard using gradil script .
open gradil file and enable minifiable true and try to sign your application

How to solve the above issue?
In prouard.project file I read
If your project uses WebView with JS, uncomment the following and
specify the fully qualified class name to the JavaScript interface
class:
I have used webview in two activity with WebAppInterface.java class.How to do above statement?

Referring resource name like "#string/on_click_handler_name", in android:onClick attribute of your layout file is ok. However, proguard cannot resolve these references.
Check http://android.okhelp.cz/proguard-parseexception-expecting-class-member-name-before/ for more details.
Find corresponding value of #string/tha_lf_et_todate_onclick in your string.xml and update :
android:onClick="#string/tha_lf_et_todate_onclick"
to
android:onClick="onClickXXX"
in your layout file.
For the second question,
uncomment that piece of code, and replace "fqcn.of.javascript.interface.for.webview"
with the class's fully qualified name.

can anyone help me with this to resolve this error msg?

Try changing the the parenthesis following the PLD instruction to brackets. That is, change
PLD (xx xx)
to
PLD [xx xx]

Uncomment the ANDROID_JPEG_NO_ASSEMBLER line of the Android.mk, it is like that:
# temp fix until we understand why this broke cnn.com
#ANDROID_JPEG_NO_ASSEMBLER := true
do that:
# temp fix until we understand why this broke cnn.com
ANDROID_JPEG_NO_ASSEMBLER := true

trying to compile Android on Windows with Cygwin it's a pain.
Follow the guides on XDA-Developers.com to compile android under Ubuntu Linux, its easy as in a Windows Cygwin Environment and it works fine :)

i have the same error and some solutions says change PLD from UPPERCASE to lowercase
e.g. from "PLD" to "pld" .
