Proguard Error in the Google Play Services Library

Question

I added the Google Play Services application to the application. Everything works fine, but the size of my apk increases 4 (!) Times from 350 KB to 1.6 MB. To remove unused classes from the Google Play Services library, I decided to use ProGuard. But now I can not start the project or export it to apk, because ProGuard returned an error. When I do not use GPS lib, I have no problems with export, but I can not create apk with this library. I read a lot about this problem, but any solution I found did not help me.

Here is my proguard-project.txt (as recommended here )

-keep class * extends java.util.ListResourceBundle { protected Object[][] getContents(); } -keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable { public static final *** NULL; } -keepnames @com.google.android.gms.common.annotation.KeepName class * -keepclassmembernames class * { @com.google.android.gms.common.annotation.KeepName *; } -keepnames class * implements android.os.Parcelable { public static final ** CREATOR; } 

Here is my proguard.cng

 -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 #keep all classes that might be used in XML layouts -keep public class * extends android.view.View -keep public class * extends android.app.Fragment -keep public class * extends android.support.v4.Fragment #keep all public and protected methods that could be used by java reflection -keepclassmembernames class * { public protected <methods>; } -keepclasseswithmembernames class * { native <methods>; } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet); } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet, int); } -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); } -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; } -dontwarn **CompatHoneycomb -dontwarn org.htmlcleaner.* -dontwarn com.google.android.gms.** -keep class com.google.android.gms.common.GooglePlayServicesUtil {*;} -keep class com.google.ads.** { *;} 

and here is the error I received after exporting to apk:

maybe something is wrong with my local settings ... I tried -dontwarn and -dontwarn different classes, but now nothing helped ...

Please help me!

Answer 1

Add the android-support-v4.jar project to the project

Answer 2

If you use Eclipse ADT: you must reference the copy of the Google Play Services library that you copied to the development workspace - you must not reference the library directly from the Android SDK.

Answer 3

I ran into a similar problem, and several others with Prograud, when creating a signed assembly. After a lot of searching, finally I can solve my problem. I am sure that people have a better solution than lower.

• Keep the latest SDKs and supported libraries.
• Create the "libs" folder inside "/ sdk / tools / progaurd /".
• Copy the .jar files, for example, "android-support-v13.jar", "google-play-services.jar", which your application needs in the folder "/ sdk / tools / progaurd / libs /".
• Copy the .jar file to the "libs" application folder. Also remove "android-support-v4.jar" since it is not required, here v13 already supports v4
• Add the .jar file to your build path. Also remove "android-support-v4.jar" from the build path, since it is not required, here v13 already supports v4.
• Add lines to the project.properties application file. Please save the target as "android-22".

 proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt # Project target. target=android-22 android.library.reference.1=../../dev/sdk/extras/google/google_play_services/libproject/google-play-services_lib 

7. My Progaurd file is "proguard-android.txt". Please modify it according to your requirements.

Answer 4

even though I had google play services as a library, I still had to manually add android-support-v4.jar to my libs folder and right-click and add the build path to eclipse.

my proguard file looked like this:

  -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontwarn com.google.** -dontpreverify -dontwarn android.support.v4.** -dontwarn org.apache.commons.codec.binary.Base64 -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* -keep class !mycode.** { *; } 

the last line makes only my code get confused. Its cleaner.
