Android - proguard.cfg error

Question

I imported an older project after a I installed the android SDK on a new computer. I am getting the following error in the "problems" window in eclipse.

Obsolete proguard file; use -keepclasseswithmembers instead of -keepclasseswithmembernames  proguard.cfg    /MyApplication  line 1

Here is the file. I tried replacing the -keepclasseswithmembernamesin this file with -keepclasseswithmembersbut it did not help.

This is a sample config file that I use with proguard 4.4, JDK 1.6, target android 2.1. Check your proguard version by double clicking on the jar file or with java -jar android-sdk/tools/proguard/lib/proguard.jar (use android sdk install path)

-keep class * implements android.os.Parcelable {

}

Answer 2

It seems to be an Eclipse / Android SDK error i suggest

1) close the project is giving error to you 2) remove it from eclipse ( do not remove folder or source ) 3) import the project you removed 4) clean and build again

Answer 3

if Previous answer didnt help

Then just create empty Android project in Eclipse and copy/replace created "proguard.cfg" file to your project.

Answer 4

This is what helped me; Right click on project's name, and click on "Android Project". Then select "Clear Lint Markers". Seems that I had accidentally run "Lint" for checking for some common problems after which I began seeing those proguard.cfg errors. Funny thing is that even though I was compiling in debug mode, eclipse would still complain about proguard (which is supposed to be used when compiling in release mode only).

Answer 5

proguard.cfg will be in your project's root. edit it, replacing:

-keepclasseswithmembernames class * {

with

-keepclasseswithmembers class * {

worked for me running ADT bundle (v21.0.0-531062 with eclipse 3.7.2 using JDK1.7 under windowsxp).

Answer 6

selected the error in eclipse problems window. and it works for me.
