@beasonshu target不选择24的话，应该暂时不会出问题。这个问题不影响你们日常开发打包的，不过我们后面尽量把这个给避免了，以免不能预览~

bashan15 · 2016-09-01T11:34:05Z

我的也不能显示预览。但只要换一个其他没用过freeline的工程，就能显示预览。
我对AndroidStudio不是特别熟，找不到不显示的原因。

lomanyong · 2016-09-01T11:44:51Z

@bashan15 点一下工具栏的gradle sync，应该就能预览了..

beasonshu · 2016-09-02T01:45:41Z

还是不行

@lomanyong 同步也不好用。报的错误和 @beasonshu 一模一样

lomanyong · 2016-09-06T08:08:24Z

@bashan15 @beasonshu 可以再说下你们使用的as的版本以及gradle插件版本相关的信息？方便我这里复现一下情况。

beasonshu · 2016-09-08T05:54:02Z

我用的 Android studio

gradle-2.14.1-all.zip

charvenhe · 2016-09-08T05:58:55Z

@beasonshu 能否试试sample工程是否也有一样的问题呢，我们这边sample复现不了

maclaylq · 2016-09-08T08:19:45Z

同此问题，as 2.1.3，gradle 2.14.1。一直是loading状态。

maclaylq · 2016-09-08T08:51:18Z

@charvenhe sample 工程也不行

charvenhe · 2016-09-08T09:02:21Z

@maclaylq 是windows还是linux平台呢

lomanyong · 2016-09-08T09:23:01Z

@maclaylq @beasonshu @bashan15 可以试下使用这个gradle插件，看下是否可以解决预览的问题：

classpath "com.antfortune.freeline:gradle:0.6.0.1609081718"

只需修改gradle插件版本即可，runtime那些不需要修改~

maclaylq · 2016-09-08T10:41:44Z

@lomanyong 我是windows 平台。上面这个版本我重新init了一遍，不能正常预览，sdk版本换成21后，可以预览了~~，用的是sample项目。
另，不能正常编译。

lomanyong · 2016-09-08T10:44:37Z

@maclaylq 不能正常预览报的错还是之前的类似下面这些日志吗？

Expecting a stackmap frame at branch target 22 Exception Details: Location: R$styleable. ()V @10: ifeq Reason: Expected stackmap frame at this location. Bytecode: 0x0000000: 2ab7 02dc b202 e2b6 02e6 9900 0cb2 02ec 0x0000010: 1302 eeb6 02f4 b1

那个无法编译过的报错在新版本解决了，晚上就会发版。

maclaylq · 2016-09-08T10:49:39Z

@lomanyong 刚重新切过去又可以了。之前没有报错，不能正常预览是只有手机框的图片，其中的textview的内容不显示，现在又可以了。

lomanyong · 2016-09-08T10:53:11Z

@maclaylq 可以具体描述一下无法预览的现象吗？因为我这边在sample工程上一直无法复现这个问题。是指修改了内容，没有实时刷新preview的页面？

maclaylq · 2016-09-09T01:56:04Z

就是textview的长宽预览都是最小的，看不到内容，切到低版本就可以了。

lomanyong · 2016-09-09T02:24:21Z

@maclaylq 这个问题不使用freeline打包的话不会出现是吗？

qsyj · 2016-09-09T02:29:40Z

@lomanyong 0.6.1还是无法预览!
当执行完freeline.py 成功安装后,切换到布局界面,studio布局预览就消失了!

一:androidstudio 版本:2.2RC
二:classpath 'com.android.tools.build:gradle:2.1.3'
三:
compileSdkVersion 23
buildToolsVersion '23.0.2'

minSdkVersion 15
targetSdkVersion 21

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'

lomanyong · 2016-09-09T02:51:31Z

@qsyj 布局预览消失有提示什么吗？target改为低版本是否会出现呢？

kszkk · 2016-09-09T03:03:37Z

我也是用的0.6.1
xml布局文件不能渲染

lomanyong · 2016-09-09T06:33:21Z

@kszkk 切换一下preview中target的版本是否还会报错？

以及，可以检查一下${module}/build/intermediates/classes/xxxxxx/R.class，这个类以及内部类是否正常，是否多出了一个构造函数。

kszkk · 2016-09-09T06:45:17Z

@lomanyong 切换target的版本还是报这个错
我找到了R.class 但是怎么看是否多出一个构造函数？

lomanyong · 2016-09-09T07:38:36Z

@kszkk 在IDE里直接可以打开class文件，会自动反编译的。通常R.class以及他的内部类是没有构造函数的，或者构造函数是空的。反编译后的R.class的各个构造函数是否正常即可。

lomanyong · 2016-09-09T08:09:38Z

ref marker:

kszkk · 2016-09-09T08:36:16Z

@lomanyong 有构造函数

public R() {
        if(Boolean.FALSE.booleanValue()) {
            System.out.print(ClassVerifier.class);
        }

    }

其他的内部类构造函数也都是这个

lomanyong · 2016-09-09T09:10:49Z

@kszkk 你那边是windows操作系统吗？如果是的话，替换为这个版本的gradle插件，然后重新运行试试看，R.class看下是否还会出现这个情况。

gradle插件：com.antfortune.freeline:gradle:0.6.1.1609091648

kszkk · 2016-09-09T09:27:34Z

@lomanyong 这回可以了构造函数都是空的布局也能渲染出来了

charvenhe · 2016-09-09T09:34:31Z

@beasonshu @maclaylq 这个问题是否也解决了，通过使用这个新版本的gradle插件可以解决：com.antfortune.freeline:gradle:0.6.1.1609091648

maclaylq · 2016-09-13T06:22:17Z

0.6.3版本可以正常预览了。
