[2012-06-01 14:06:03 - geoTest6.3]       You should check if you need to specify additional program jars.

[2012-06-01 14:06:03 - geoTest6.3]          You may need to specify additional library jars (using '-libraryjars'),
[2012-06-01 14:06:03 - geoTest6.3]          or perhaps the '-dontskipnonpubliclibraryclasses' option.

[2012-06-01 14:06:03 - geoTest6.3]          You must avoid such dependencies, since the program classes will
[2012-06-01 14:06:03 - geoTest6.3]          be processed, while the library classes will remain unchanged.

解决办法：因为采用了三方的jar包，需要我们在 proguard.cfg 中添加"-dontwarn"

如下：

proguard.cfg 全部配置

-dontwarn
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
native <methods>;
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}

-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}

可解决！
