blocks|key|4325437|text|好了，那些想知道我是怎么解决这个问题的人。解决方案很简单，但你可能不会喜欢它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4325438|我必须将项目根包中用于数据绑定的所有类移动到项目根包中，并且在它开始再次工作之后。|4325439|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Ok, so those who are wondering how I fixed this.
The solution is quite simple but probably you won't like it.

I had to move all my classes that were used in data binding in the project root package and after it started to work again.

blocks|key|4325560|text|只需在graddle-wrapper.properties文件中注释掉这些行，就可以帮助我解决问题|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4325561|#android.enableExperimentalFeatureDatabinding+=+true

Just Commenting these lines out in <code>graddle-wrapper.properties</code> file helped me solve my problem 

<pre><code>#android.enableExperimentalFeatureDatabinding = true
#android.databinding.enableV2=true

if you're using kotlin on android studio 3.2 ,
replace the distributionurl with this line 

<pre><code>distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
</code></pre>

and you'll be asked to change the build tools version to the apprpriate version.
once you've done that , remove this line from the app level build.gradle file

<pre><code>kapt 'com.android.databinding:compiler:3.0.1
</code></pre>

and build the project. it worked for me.

This one is a very tricky bug with android studio and databinding! I had to test all this proposed solutions and some more for an entire day to finally make the databinding compile at least.

So I had to disable all databindind settings in <code>gradle.properties</code> file, just comment these lines or delete them:

<pre><code>android.databinding.enableV2 = true
android.enableExperimentalFeatureDatabinding = true
</code></pre>

remove <code>buildToolsVersion</code> from <code>build.gradle</code> and have the following sdk versions:

<pre><code>compileSdkVersion 27
defaultConfig {
 minSdkVersion 21
 targetSdkVersion 27
 versionCode 1
 versionName "1.0"
 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
</code></pre>

Plus a couple more clean/rebuild invalidate caches and restart, and it FINALLY compiled.
AS engineers are great at creating bugs!

blocks|key|4325660|text|如果您使用数据绑定，请检查您的xml文件。我今天浪费了一个小时，因为我重命名了一个类，Android+Studio决定对我的xml文件进行更改。例如，我有一个名为LiveGameModel的类，我将其重命名为LiveGameView，并决定对与此视图无关的xml文件进行更改。我知道，这个bug说不通。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4325661|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Check your xml files if you are using databinding. 
I wasted one hour today because I renamed one class and Android Studio decided to make changes in my xml files. 
For example, I had a class named LiveGameModel and I renamed to LiveGameView and AS decided to make changes in xml files which are not related to this view. I know, this bug doesn't make sense.

blocks|key|4325722|text|这可能看起来很奇怪，但我浪费了几个小时面对这个错误，在检查了我最新的更改后，我发现它与Room数据库中的一个错误有关。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4325723|我声明了一个Dao接口，但忘了用@Dao替换它。|offset|length|style|CODE|4325724|在修复了数据绑定错误之后。|4325725|我猜这是android+studio的一个bug。|4325726|entityMap^0|0|G|4|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

This may seems strange but I wasted a few hours facing the error and after a inspection in my latest changes I found that it was related to an error in Room database. 

I declared one of the Dao interface but forgot to anotate it with <code>@Dao</code>.

After fixing that the data binding error was fixed. 

I guess this is a bug of android studio.

I got this error after making some modifications in Room Entity classes. So I feel that This error is somehow related to Room library. Try to revert changes in Room classes and entities or comment them to see if error is fixed. 

In my case the error appeared because I was returning <code>int</code> from insert and update methods. These methods should not return anything. So removing <code>return</code> fixed the error.

<pre><code>@Insert(onConflict = OnConflictStrategy.REPLACE)
 fun insert(student: Student):Int
</code></pre>

to 

<pre><code>@Insert(onConflict = OnConflictStrategy.REPLACE)
 fun insert(student: Student)

I was having the same issue. I disabled databinding in gradle properties and it worked. <code>dataBinding.enabled = false</code>

This morning I made an update to <code>android studio</code> from 3.0.1 to 3.1.0. After updating the <code>gradle</code> to latest version I still get build error regarding data binding.

My <code>gradle-wrapper.properties</code>:

<pre><code>distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
</code></pre>

All my errors are like the one below:

<pre><code>/Users/mp/Documents/GitHub/projectx/app/build/generated/source/dataBinding/baseClasses/Staging/debug/me/projectx/asdasd/databinding/GridItemActivityTypeBinding.java:57: error: cannot find symbol
 @Nullable DataBindingComponent component) {
 ^
 symbol: class DataBindingComponent
 location: class GridItemActivityTypeBinding
</code></pre>

Does anyone have any idea why would my data binding not generate after the android studio 3.1 update? Thanks in advance

Edit 1: Forgot to say, I tried clean/rebuild/invalidate cache &amp; restart/deleted build folder.
