在更新 新版AndroidStudio3.0.1的时候(原来用的是2.1版本),遇到的两个问题,感觉有必要注明一下
问题一、编译时报错Error:Removing unused resources requires unused code shrinking to be turned on.
修改build.gradle文件,下面标红代码就是
buildTypes { debug { signingConfig signingConfigs.release buildConfigField "boolean", "ISDEBUG", "true" debuggable true minifyEnabled true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } release { signingConfig signingConfigs.release minifyEnabled true zipAlignEnabled true debuggable true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }
问题二、运行时报错
> Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration.
- butterknife-7.0.1.jar (com.jakewharton:butterknife:7.0.1)
Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future.
See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
在app的build中添加
android { ... defaultConfig { ... //添加如下配置就OK了 javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } } } ... }
