android -progaurd keeps erroring with parse

This is my proguard rules :
-keepattributes SourceFile,LineNumberTable
-keep class com.parse.*{ *; }
-keepclasseswithmembernames class * {
native <methods>;
}
i've searched and used lots of codes but none of them worked . these are the errors I got :

You should check if you need to specify additional program jars.
please do not tell me to use dontwarn ,yes it manage to build the app but the app will not be run
How can I solve this problem ?

You have to use this
-keep class com.parse.** { *; }
i.e. ** instead of *
and maybe this too
-keepattributes *Annotation*

Please try to use below in your progaurd file :
#Parse
-keep class com.parse.** { *; }
-keepattributes Signature
Hope It will help.!!

android -Progaurd return error 1

I want to use proguard for my application , I'm using eclipse . This is the config file :
-dontwarn com.parse.**
-keep class com.facebook.** {

-keepattributes Signature

Error in Jackson.jar when running proguard in android

I have an android project that uses jackson-all-1.7.2.jar.

-keep class org.holoeverywhere.** {*;}

The file jackson-all-1.7.2.jar is already in your libs directory, so the Android Ant/Eclipse builds will pick it up automatically. You shouldn't read it again with -libraryjars, because then you'll get these warnings about duplicates.
Jackson is using reflection to find some annotations. ProGuard can't deduce this automatically, and it ends up removing related, seemingly unused fields. This configuration should keep them:
-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *;
}

Add these line in your proguard configuration file.
-keepnames class com.fasterxml.jackson.** {
*;
}
-keepnames interface com.fasterxml.jackson.** {
*;
}

android proguard causes apk to crash

My app works fine in debug and also when I export to a signed apk if I have proguard disabled by commenting out "proguard.config=${sdk.dir}/tools/proguard..." in project.properties.
However, if I uncomment that line I get a bunch of warnings and proguard won't create the apk. I can suppress the warnings by adding the following lines to proguard-project.txt
-dontwarn com.sun.mail.imap.protocol.**
-dontwarn org.apache.harmony.awt.**
-dontwarn javax.activation.**
and the apk will get created but it will not execute in the phone. Interestingly, if I remove these lines and use "-dontshrink" I continue to get these errors. I would have thought that would get rid of the problem.
I found in http://developer.android.com/tools/help/proguard.html that I am probably missing some -keep lines in my configuration but it is not obvious what these would be. Can anyone provide a clue?
The default proguard.cfg file tries to cover general cases, but you
might encounter exceptions such as ClassNotFoundException, which
happens when ProGuard strips away an entire class that your
application calls.
You can fix errors when ProGuard strips away your code by adding a
-keep line in the proguard.cfg file. For example:
-keep public class

Maybe a bit late, but searching for a solution to a similar problem, I learned that you have to tell proguard to keep some classes in your libs jars. Refer to the log where it says Warning: ... and can't find referenced class ....
So in your case should be:
-keep class javax.security.** { *; }
-keep class java.beans.** { *; }
-keep class java.awt.** { *; }
and
-libraryjars libs/XYZ.jar
for every jar into /libs containing those classes.

Android Proguard skip external jar

I tried to use Proguard in my Android project, i setup Proguard using command line 'android update project /path/to/project' and file proguard.cfg was created in project's root directory. (In my Eclipse with Android 2.3 sdk, when create a new project, proguard.cfg file is not automatically created so i have to add it manually using command line).
When i export the project, i got the following errors

I've tried some solutions found on web by adding '-libraryjars' option, ex:
-libraryjars /Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar
but it won't help.
Any solutions?

Your library jars refer to yet more library jars (Mortbay, SLF4J, Apache Commons Logging, Log4j, ...) Adding these jars with extra '-libraryjars' options should solve the problem.
If you are absolutely sure that your code doesn't use these libraries, you can specify '-ignorewarnings' or '-dontwarn', e.g.
-dontwarn org.mortbay.**
-dontwarn org.slf4j.**
-dontwarn org.apache.log4j.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.apache.commons.codec.binary.**
