[2014-07-15 23:57:43 - MozMeet] Error: Please correct the above warnings first.
This is the list of errors that I get when I try to export my Android app with ProGuard enabled. A little bit of Googling and I found that I need to add jar files to the proguard-project.txt. So far what I have added looks like this (but to no avail):
-keepattributes SourceFile,LineNumberTable
-keep class com.parse.*{ *; }
-libraryjars \libs\Parse-1.5.1.jar
-keepclasseswithmembernames class * {
native <methods>;
}
I also have 3 more libraries along with Parse namely Crashlytics, Picasso and V4 Support.

Made a few changes to proguard-project.txt file (if you have more than one module in your project - put it in the module which calls the *.jar file you are getting warned about):
-keepattributes SourceFile,LineNumberTable
-keep class com.parse.*{ *; }
-dontwarn com.parse.**
-dontwarn com.squareup.picasso.**
-keepclasseswithmembernames class * {
native <methods>;
}
The -dontwarn lines were needed. Basically what they tell ProGuard is that these jars work fine on their own so don't complain when you cannot find the classes they reference.

Android Proguard SqlCipher NoClassDefFoundError

Have been battling with Proguard all day and have tried many examples and solutions on the official Proguard site as well as StackOverflow.
I have a large project I need to obfuscate, which has a number of referenced library projects and Jars.
I am getting 725 warnings from proguard from 2 libs, com.google.common and twitter4j.
I can happily get the project to compile if I add the following:
-dontwarn com.google.common.**
-dontwarn twitter4j.**
However, the app crashes instantly on open, so this seems to just be a way of hiding an issue, not fixing it.
The proguard-project.txt is in the project root and its config is in the project.properties file as below.
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
Here is my proguard-project.txt file

These are the config I've used in the past for SQLcipher
-keep public class net.sqlcipher.** {
*;
}
-keep public class net.sqlcipher.database.** {
*;
}

I'll suggest you to add thoses 2 lines in your proguard file :
-dontwarn javax.management.**
-dontwarn org.apache.commons.logging.**

-keep class net.sqlcipher.** { *; }
-dontwarn net.sqlcipher.**

Build Google SDK example with Eclipse with release mode

I try to build Google Drive SDK examples in Eclipse v22.01:
(The example website is as follows:)
https://developers.google.com/drive/quickstart-android
When I used debug build,it builded fine and executed fine on my table device.
However, when I tried to build it on release mode, I failed.
My process is as follows:
1. Go to "File"->"Export"
2. Create private keystore (This step succeeded.)
3. Build apk
I've checked the post Update your Proguard and downloaded and replaced jars in Proguard
I also checked the postCheck the '"Android Private Libraries' and checked items on "Order and Export" tab. But Still failed.
[Edit 1] I found the solution.
Just Uncheck the 'Drive API' (See the picture for reference)
(I am not sure if 'Android Dependencies' is needed or not. Maybe this could also be unchecked.)
I also add '-dontwarn com.google.**' to 'proguard-android.txt'
And then it worked.
Here are the errors messages I got:

I found the answer, Please refer the "Edit 1" part.
Hope this would help anyone who got the same problem.

From your screenshot (you have the google-play-services.jar), it looks like project isn't being built correct and this will only lead to more issues in the future.
Based on the link you provided, https://developers.google.com/drive/quickstart-android that documentation Does tell you to just use the jar.
However, there are more complete instructions at https://developer.android.com/google/play-services/setup.html
Here it instructs to
use the library project at /extras/google/google_play_services/libproject/google-play-services_lib/
make proguard entries
modify your AndroidManifest.xml

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.**
