Problems encountered in Android studio 3.0 upgrade project and change ideas (summary of problems)

Android studio has added many functions from version 3.0. Of course, the first is the new support for kotlin development language from version 3.0. In addition, there are other new functions, such as Android profiler (including CPU profiler, memory profiler and network Profiler), APK debugger, device file explorer, Java 8 language features, etc.

Android studio version 3.0 upgrade problem modification:

===Question 1

===Solution:

Warning:android-apt plugin is incompatible with future version of Android Gradle plugin. Please use ‘annotationProcessor' configuration instead.

Cause: there is a problem updating the original project of Android studio.

Analysis: especially for those who use the butterknife tool and the new Android studio, I guess the reason may be that Android studio is updated and gradle is updated. In this way, the original Android apt tool may not keep up with the section, so let's use the annotationprocessor tool.

Solution: put the dependency in build.gradle under project

Amend to read as follows:

Then add build.gradle under module:

Amend as follows:

Delete the reference to apply plugin: 'com. Neenbedankt. Android apt'.

Rebuild

===Question 2

Error:Execution Failed for task ':wigetlib:javaPreCompileDebug'. > 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.

In the build of app
