Error: cannot set readonly: proguardFiles property for class: com.android.build.gradle.managed.BuildType

Question

I am trying to run an example AR application from: https://artoolkit.org/documentation/doku.php?id=4_Android:android_examples

I tried to open the ARSimpleProj project. But this gives me this error:

Error:Cannot set readonly property: proguardFiles for class: com.android.build.gradle.managed.BuildType 

I am using Android Studio 2.2.2 and Gradle 2.14.1

Thanks!

Answer 1

I got the same error the last few hours. I decided to change the assembly type as follows:

 buildTypes { release { minifyEnabled false proguardFiles 'proguard-rules.pro' } } 

After that, I deleted the entire imported line of ndk code. So my build.gradle for aRimple is

 apply plugin: 'com.android.model.application' model { android { compileSdkVersion = 23 buildToolsVersion = "23.0.1" defaultConfig.with { applicationId = "org.artoolkit.ar.samples.ARSimple" minSdkVersion.apiLevel = 15 targetSdkVersion.apiLevel = 22 versionCode = 1 //Integer type incremented by 1 for every release, major or minor, to Google store versionName = "1.0" //Real fully qualified major and minor release description buildConfigFields.with { //Defines fields in the generated Java BuildConfig class, in this case, for create() { //default config, that can be accessed by Java code type = "int" //eg "if (1 == BuildConfig.VALUE) { /*do something*/}". name = "VALUE" //See: [app or lib]/build/generated/source/buildConfig/[package path]/ value = "1" // BuildConfig.java } } } } buildTypes { release { minifyEnabled false proguardFiles 'proguard-rules.pro' } } android.productFlavors { } } dependencies { //compile 'com.android.support:support-v4:23.0.1' //compile 'com.android.support:appcompat-v7:23.0.1' //Only required when the target device API level is greater than compile project(':aRBaseLib') } //the compile and target of the app being deployed to the device 

Then I create and copy the entire .so library file to the jnilibs folder in the main application folder, as shown in the figure

Then run yours. I do not know what this solution is for this. But errors go, and the project starts without errors. Tell me if you find any other solution for this. Thanks.

According to this description , in version 0.4.0, '+ =' was chosen and use ".add ()" for it instead. So make an expression

proguardFiles += file('proguard-rules.pro')

change to

proguardFiles.add(file('proguard-rules.pro'))

and the error will disappear

The build.gradle file now looks like this: pay attention to the changes. Made 2-3 changes but now it works absolutely fine. Code below: -

  apply plugin: 'com.android.model.application' model { android { compileSdkVersion = 23 buildToolsVersion = "23.0.2" defaultConfig.with { applicationId = "org.artoolkit.ar.samples.ARSimple" minSdkVersion.apiLevel = 15 targetSdkVersion.apiLevel = 22 versionCode = 1 //Integer type incremented by 1 for every release, major or minor, to Google store versionName = "1.0" //Real fully qualified major and minor release description buildConfigFields.with { //Defines fields in the generated Java BuildConfig class, in this case, for create() { //default config, that can be accessed by Java code type = "int" //eg "if (1 == BuildConfig.VALUE) { /*do something*/}". name = "VALUE" //See: [app or lib]/build/generated/source/buildConfig/[package path]/ value = "1" // BuildConfig.java } } } } android.buildTypes { release { minifyEnabled = false proguardFiles.add(file('proguard-rules.pro')) } } android.productFlavors { } android.sources { main{ jni { source { srcDirs = ['src/main/nop'] } } } main{ jniLibs { source { srcDirs = ['src/main/libs'] } } } } } dependencies { compile project(':aRBaseLib') }

Retrieving files from Github fixed it for me. I followed a short read of what they had to associate files with where you saved the SDK and reopened from this directory. I could not get this answer to work for me. Maybe something has changed since I had all .so libs; otherwise I did it wrong.
