Signed apk getting crashed in proguard enable

I am trying to use proguard in my app set the proguard to true and then the problem starts I am importing lib when I use proguard by following this
-keepnames class com.somepackage.* with my package name the app is getting getting crashed when I try to use the signed apk. I know this iS a dumb question but I am stuck at this for last 5 hr not able to find an easy solution as I am using about 20 lib. I followed this also. Plz guide me in this how can I do this?
This is my proguard rule class code
-keepnames class beatbox.neelay.dummybeat.*
-keepnames com.srx.widget.*
-keepnames de.hdodenhof.circleimageview.CircleImageView.*
-keepnames com.bumptech.glide.*
-keepnames com.romainpiel.shimmer.*
-keepnames com.vansuita.gaussianblur.GaussianBlur
-keepnames com.antonyt.infiniteviewpager.InfinitePagerAdapter
-keepnames com.antonyt.infiniteviewpager.InfiniteViewPager
-keepnames com.eftimoff.viewpagertransformers.CubeOutTransformer
-keepnames com.ms.square.android.glassview.GlassView
-keepnames me.alexrs.fontpagertitlestrip.lib.FontPagerTitleStrip
I am not able to generate any signed apk now . the error is.

the dependency tree

Reason :
Not every Class or Library are optimized with Proguard enabled , So what Proguard do is that it removes classes if they are not optimize which results crash and bugs in project.
Solution : In your proguard.cfg file keep that classes or library which are not supported by progaurd . Try the catch all described here :
Try adding :
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
Or , if you are using v4 lib :
-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
If you are using latest android studio you might found this as proguard-rules.pro
In your case try using -dontwarn as well with classname. Like your error show that it can not optimize circleimageview Library . so try to add this as well :
-dontwarn hdodenhof.**
-keep class hdodenhof.**
If still not working than downgrade your circleimageview library : compile 'de.hdodenhof:circleimageview:1.3.0' This is working for me.

1) Keep all annotations
-keepattributes SourceFile,LineNumberTable,*Annotation*,EnclosingMethod,Signature,Exceptions,InnerClasses
2) Keep if you have any pojos or models and classes which are using for network call
Ex:
-keep class com.example.android.models.**
-keepclassmembers class com.example.android.models.** {
*;
}
-keepclassmembers class com.example.android.network.** {
public void set*(***);
public *** get*();
public *** is*();
}
3) For all the libraries you are using keep below proguard rules
Ex:
-dontwarn com.zl.reik.dilatingdotsprogressbar.**
-keep class com.zl.reik.dilatingdotsprogressbar.**{*;}
-keep interface com.zl.reik.dilatingdotsprogressbar.**{*;}
You even need to keep similar proguard rules for "foldingtabbar", as It is also a library
If the above solution does not solve, run ./gradlew app:dependencies in your repository and Send me the list of dependencies

Having the same version for all the support libraries is also very important. Sometimes libraries have recursive dependencies, where each has a different version which can lead to this error. Run:
./gradlew app:dependencies
to see the dependencies for each library and check whether they all have the same version. I already see, that you use 25.1.0 and 25.2.0 versions of support libraries. In addition, some of your libraries are old, thus, they probably use old versions.
Try to use:
-keep class beatbox.neelay.dummybeat.**{*;}
-dontwarn beatbox.neelay.dummybeat.**
instead of:
-keepnames beatbox.neelay.dummybeat.**{*;}

Proguard removes classes which are part of dependencies added the app. Try to keep them using:
-keep class hdodenhof.**
-keep class android.support.v4.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
Disable warning for dependency classes:
-dontwarn hdodenhof.**
-dontwarn android.support.v4.**
-dontwarn android.support.v7.**

This configs work fine on 22 android SDK, but after update to 24 got error.
I try add next but not success:
-keep class com.google.android.gms.analytics.**
-keep class com.google.analytics.tracking.**
-dontwarn com.google.android.gms.analytics.**
-dontwarn com.google.analytics.tracking.**
What is my error and what is a solution?

I ended up with the following proguard options:
# WORKAROUND for building project with GMS (google play services)
-keep class com.google.android.gms.iid.zzd { *; }
-keep class android.support.v4.content.ContextCompat { *; }

This is caused by buildtools working with 8.4 version of google play services. I tried excluding the particular class from optimization with -keep, but it didn't work. I ended up with migrating to google play services 9.0.2:
classpath 'com.android.tools.build:gradle:2.0.0'
classpath 'com.google.gms:google-services:3.0.0'
...
buildToolsVersion "24.0.0"
...
// google play services
compile ('com.google.android.gms:play-services-gcm:9.0.2')
compile ('com.google.android.gms:play-services-analytics:9.0.2')
...

Try using version 9.2.1; it seems they have fixed a proguard issue. Based on the release notes.
Refer link: https://developers.google.com/android/guides/releases

If you don't feel like bumping the play services just yet, you can also turn off the following optimizations in ProGuard, e.g.
-optimizations !method/marking/private,!method/marking/static,!method/removal/parameter,!method/propagation/parameter
Obviously, this might mean a performance hit, so use judiciously.

butterknife is not working when in signed apk

I created an app using butterknife to implement onclick, ontouch,etc function, it works fine when I test it on my android devices, and it also works good when I install the debug-apk in the android deivces. However, when I generated an signed apk and try to run it in my android device, the "onclick" and "ontouch" are not working.I generated the apk using Android studio. Anyone knows the reason why this happens?

Copied from http://jakewharton.github.io/butterknife/
Use these rules in proguard-rules.pro file
-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }
-keepclasseswithmembernames class * {
#butterknife.* <fields>;
}
-keepclasseswithmembernames class * {
#butterknife.* <methods>;
}

Add
-keepnames class * { #butterknife.Bind *;}
to the proguard file

Getting warnings and errors after enabling proguard

I enabled proguard for my release build and when I ran the project, I get these warnings and errors. Here is my buildTypes block:
buildTypes {
release {
minifyEnabled true
//shrinkResources true
signingConfig signingConfigs.myConfig
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
The build message was too long to post here so have put external link.
What is the reason for these warnings? Is there something I have done wrong? How can I fix this?

for any external library that you are using you need to add rules in your proguard.pro file.
For example in my project these are the proguard rules I added for retrofit and okhttp
# Retrofit 1.X
-keep class com.squareup.okhttp.** { *; }
-keep class retrofit.** { *; }
-keep interface com.squareup.okhttp.** { *; }
-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
-dontwarn retrofit.**
-dontwarn rx.**
-keepclasseswithmembers class * {
#retrofit.http.* <methods>;
}
These rules are taken from
https://github.com/krschultz/android-proguard-snippets/blob/master/libraries/proguard-square-retrofit.pro
So you need to check similarly for each library what are the rules to be added.

Each library mentioned in the warnings has its' own proguard rules which you have to put in your proguard-rules.pro. For example you can find ButterKnife's rules at http://jakewharton.github.io/butterknife/ "Proguard" section.

Can I write some of the code in Scala (using AndroidStudio)?

I'm using AndroidStudio, and I want to stick to using it because it's the official IDE.
All I want to do is to be able to write some classes in Scala, sounds reasonable to me.
However, all I could find online is a way to create a new project using SBT (+ Android plugins and idea plugin) then load it in AndroidStudio. Of course, I had to deal with all the strange errors and the like until I finally made it compile and run on the emulator. But then I tried to add a fragment drawer and again I ran into problem because I need to add some extra Android libraries and I have no clue to do that.
The sane approach should be to use AndroidStudio as it is (because it's the official IDE) and be able to add Scala files somehow that then get compiled into java bytecode then get treated like normal Java code by the Android compiler. Is there a way to do that?

I use Scala and Gradle (yeah, I know Gradle is written in Groovy). It's a pain to get set up at first, but I like Scala a lot, so it is worth it.
To do it you will need to rely on a groovy plugin. Here is what you do:
1. Add classpath "jp.leafytree.gradle:gradle-android-scala-plugin:1.3.1" to your top-level gradle file like so (also work around the problem with proguard):
build.gradle (top-level):
buildscript {
repositories {
mavenLocal() // Remove this if your repository is not local
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:1.0.0"
classpath "jp.leafytree.gradle:gradle-android-scala-plugin:1.3.1"
// Default version of proguard v4.8 (?) and v5.1 fail with ArrayIndexOutOfBoundsException: 4
classpath ('net.sf.proguard:proguard-gradle:5.0') {
force = true
}
...
2. Apply your plugins and set the Scala dependency in the module, like "app" or "wear", level gradle file:
build.gradle (module-level):
...
apply plugin: "jp.leafytree.android-scala"
android {
...
buildTypes {
release {
debuggable false
minifyEnabled true
...
debug {
debuggable true
minifyEnabled true
...
}
dependencies {
...
compile 'org.scala-lang:scala-library:2.11.4'
}
3. Make sure you are using Proguard (Scala code has to be minified to work with Android). Here is the main proguard file I use--you will want to change that "keep public class" line at the top to match your project domain:
proguard-rules.pro:
-dontpreverify
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontusemixedcaseclassnames
# ----
-dontoptimize
# ----
-keep public class com.keithpinson.** { public protected *; }
##
## SCALA SETTINGS
##
-dontwarn scala.**
-dontnote scala.Enumeration
-ignorewarnings
# temporary workaround; see Scala issue SI-5397
-keep class scala.collection.SeqLike {
public protected *;
}
-keep class scala.math.ordering { *; }
-keep class scala.Function1 { *; }
-keep class scala.Function2 { *; }
##
## ANDROID SETTINGS
##
-keep class android.support.v13.** { *; }
-keep interface android.support.v13.** { *; }
-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 *;
}
# Joda Time 2.3
-keep class org.joda.time.** { *; }
-keep interface org.joda.time.** { *; }
If I haven't forgotten something and Gradle is downloading the leafytree plugin and if you have the right versions of Scala and Android, it should work fine.
