Error "java.exe" exited with code 1 - Xamarin

Question

I want to reduce size of .apk file, so I am checking Enable ProGuard option in Android project's property window but getting compile time errors

Error "java.exe" exited with code 1.

I tried few things like

• Head size is already 1G.
• Android target version is 9.0(Pie).
• My Solutions Configuration in Release mode.

I am using proguard 4.7 file. I can't use latest proguard file as I am not allowed to download any external files. How can I fix this issue?

Answer 1

After a long research I have found solutions for this issue.

First download latest Proguard file from here unzip and copy to sdk path C:\Program Files (x86)\Android\android-sdk\tools, this path could be different in your case.

There must be already one proguard folder, rename that to proguard.old. Now from proguard.old folder copy and paste proguard-android, proguard-android-optimize, proguard-project files to newly created proguard folder.

After that need to follow below steps

• Create txt file somewhere in your PC and change extension to .cfg.
• Change proguard.cfg file Encoding using Notepad++ to UTF-8 without BOM and Save As somewhere.
• Now add this new proguard.cfg to your android project level.
• Change proguard.cfg file build action to ProguardConfiguration
• Clean your project.

If you are getting warnings with prefix progurd like this

PROGUARD : warning : com.appdynamics.eumagent.runtime.private

Now you need to add this package to your custom proguard.cfg file like

-dontwarn com.appdynamics.eumagent.runtime.**

With -dontwarn do not use keyword class. Here ** takes all child classes of given package.

If you are getting exception then you need to find out which library causing issue and add that in proguard.cfg file with -keep keyword

-keep public class android.support.v7.widget.** { *; } 

If you see your full log carefully progaurd gives all warnings to make us easy to find out issue.
