记升级Android Studio3.0时遇到的几个问题

今天收到了Android Studio3.0更新推送,在升级过程中遇到几个问题,在这里把问题和解决方法记录下,方便要升级的童鞋。如果还有童鞋遇到不同的问题,也可以评论下我做下记录

1.gradle打包,自定义apk名称代码报错(Cannot set the value of read-only property 'outputFile' )
  • 报错

    Error:(56, 0) Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
    Open File
    

  • 解决 :修改文件名代码请这样写

    android.applicationVariants.all { variant ->
                    variant.outputs.all {
                        outputFileName = "xinlebao_${defaultConfig.versionName}_${releaseTime()}.apk"
                    }
                }
    

2. AAPT2 编译报错 AAPT2 error
  • 报错

    Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
    
  • 解决:在gradle.properties中关闭APPT2 编译

    android.enableAapt2=false
    
  • 注:如果是eclipse转到as上的项目,可能没有gradle.properties文件,请在项目根目录中手动创建

PS:有童鞋评论说这个问题如何一劳永逸的解决。我查了下资料,as3.0默认使用appt2对图片进行编译,这个问题可能是由于.9图的格式不规范导致,编译后,确定下哪张.9图的问题,最后再用draw9patch编辑保存下即可,当然你也可以选择关闭appt编译。这个问题不是针对所有项目的,而是会出现在.9图有问题的项目中

3.apt插件问题(Error:Cannot choose between the following configurations of project :mylibrary:)
  • 报错:

    Error:Cannot choose between the following configurations of project :mylibrary:
    
    - debugApiElements
    - debugRuntimeElements
    - releaseApiElements
    - releaseRuntimeElements
      All of them match the consumer attributes:
    
  • 解决

    //1.在project的build.gradle中删除
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    //2.在module的build.gradle中删除
    apply plugin: 'android-apt'
    //3.将module的build.gradle文件中的dependency
    apt  'com.jakewharton:butterknife-compiler:8.1.0'
    //改为
    annotationProcessor  'com.jakewharton:butterknife-compiler:8.1.0'
    

其他使用apt的依赖,也要这样更改

4.Android Studio3.0 preview已知bug(Error:Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error)
  • 报错
Error:Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error include:

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
  • 解决
  1. 尝试升级kotlin版本,不过该问题可能存在于preview版本中
//在build.gradle文件中将kotlin版本从
ext.kotlin_version = '1.1.2-3'
//改为
ext.kotlin_version = '1.1.2-4'

2.尝试降低Butterknife的版本

//将Butterknife的版本降级为8.4.0
compile 'com.jakewharton:butterknife:8.4.0'
