Architecture-samples: Shrinker error: extraneous input '[]' expecting ')'

[Jack-Xiao]

I download the android-architecture-todo program, and them i run it. but i got wrong, the follow is the message. I don't know how to do ?

[foolchen]

I encountered the same problem.

[foolchen]

When I change minifyEnabled to false, the problem is solved .

[JoseAlcerreca]

The problem is only hidden if you do that, and your method count will be bigger.

proguard-android.txt is the SDK's proguard file. I have not seen that error, let me investigate.

[JoseAlcerreca]

What sample were you trying to build? I just updated todo-mvp to use the gradle plugin 2.1.0, from 2.1.0-beta3, can you try again?

[Jack-Xiao]

@foolchen thanks, It's work! however, what's happen.
@JoseAlcerreca the project is architecture-todo base model, and solved this problem follow foolchen method.

[JoseAlcerreca]

Again, disabling the minifier doesn't solve the problem.

When you say base model do you mean todo-mvp?

Can you try with 2.1.0?

[Jack-Xiao]

Yes, the todo-mvp,and link: https://github.com/googlesamples/android-architecture/tree/todo-mvp/
my project gradle version is also 2.1.0, and i share the problem todo-mvp project in my github :https://github.com/Jack-Xiao/todoapp

Same problem here.
Gradle 2.1.0 and with Android Studio 2.1.1 in Windows
Try to build every official model and fail with same error

P.S. Problem only occurred after the update of May, 13th, which I believe is AS 2.1 --> 2.1.1 and support library update.

[JoseAlcerreca]

@Jack-Xiao are you on Windows too?

[JoseAlcerreca]

I've reported the problem to the build tools team.

[Jack-Xiao]

thanks

Hi, this is Michal from the build tools team. I can't reproduce the problem, I tried git commit 10fbc69c71baa1ed8f963a68dd9f8c6fb990b12d in android-architecture, todo-mvp branch - and it built just fine. Are you using the same branch/project/commit? If not, can you post the commit number where you see the problem?

[malmstein]

These two lines in the default proguard-android.txt file are the issue:

void set*(%[]);
%[] get*();;

As a quick fix this is how I made it work in the Content Providers sample:

https://github.com/googlesamples/android-architecture/blob/dev-todo-mvp-contentproviders/todoapp/app/proguard-android.txt

Basically, grabbing the default proguard-android file and adding it to the folder:
https://github.com/googlesamples/android-architecture/blob/dev-todo-mvp-contentproviders/todoapp/app/build.gradle#L22

[Jack-Xiao]

@benol i also use gradle version 2.1.0.
@malmstein it work with your file. It seems remove the problem getter setter method, and change Listener method? And, what happend. All of us maybe want to know.

[bendowski]

I can reproduce now, thanks. It's a known issue with the parser in 2.1, it's been fixed for 2.2.

[JoseAlcerreca]

Please replace

minifyEnabled true

with

minifyEnabled false

for the debug buildType, until 2.2 is out.

[JoseAlcerreca]

This has been fixed in the tools, we'll update all samples next week.
