Android Studio 3.0 清单错误:未知元素 <action>成立 [英] Android Studio 3.0 Manifest Error: unknown element <action> found
问题描述
注意:请不要将此"android.enableAapt2=false"作为答案发布.它不是解决方案.它只是忽略了在运行时不会引起任何问题的真正错误.
解决方案很简单，只是删除了错误放置在清单文件中意图过滤器之外的动作标签.
有一个由 Android Studio 2.3 构建的应用程序.更新 Android Studio 3.0 Stable 后，开始出现此错误并且无法构建我的项目.
这里是我的 manifest.xml
<应用程序android:name=".ApplicationClass"机器人:allowBackup =真"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"机器人:大堆=真"android:supportsRtl="true"android:theme="@style/AppTheme"><!--其他不相关的东西--><action android:name="com.google.android.c2dm.intent.REGISTRATION"/><接收器android:name="com.google.android.gms.gcm.GcmReceiver"机器人:出口=真"android:permission="com.google.android.c2dm.permission.SEND"><意图过滤器><action android:name="com.google.android.c2dm.intent.RECEIVE"/><category android:name="com.xxx.xxx"/></意图过滤器></接收器></应用程序>错误显示这一行:
如果我注释/删除此操作标记行，项目构建良好，但 GCM 需要它，我无法删除它.
如您所见，错误不在主清单文件中发生，发生在/build/intermediates/manifests/full/debug/AndroidManifest.xml
尝试清理、重建、禁用即时运行.有什么解决办法吗?

<块引用>使用 AAPT2 时的行为变化
为了改进增量资源处理，Android 插件 3.0.0 默认启用 AAPT2.尽管 AAPT2 应该立即适用于较旧的项目，但本节介绍了一些您应该注意的行为更改.
Android 清单中的元素层次结构
在以前版本的 AAPT 中，嵌套在 Android 清单中不正确节点中的元素要么被忽略，要么导致警告.例如，考虑以下示例:
<申请...<activity android:name=".MainActivity"><意图过滤器><action android:name="android.intent.action.MAIN";/><category android:name="android.intent.category.LAUNCHER";/></意图过滤器><action android:name="android.intent.action.CUSTOM";/></活动></应用程序></清单> 以前版本的 AAPT 只会忽略错位的标签.但是，使用 AAPT2 时，您会收到以下错误:
AndroidManifest.xml:15: 错误:未知元素 成立. 要解决此问题，请确保您的清单元素嵌套正确.如需了解详情，请阅读清单文件结构.>
NOTICE: Please do not post this "android.enableAapt2=false" as an answer. It is not a solution. It is just ignoring the real error which is not causing any problem on runtime.
Solution was simple, just removed mistakenly placed action tag outside of an intent filter in the manifest file.
Have an application which was building by Android Studio 2.3 fine. After updating Android Studio 3.0 Stable, started to having this error and unable to build my project.
Here my manifest.xml
<application
android:name=".ApplicationClass"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<!--other unrelated stuff-->
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.xxx.xxx" />
</intent-filter>
</receiver>
</application>
Error shows this line:
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
If I comment/remove this action tag line, the project builds fine but it is necessary for GCM and I cannot remove it.
As you see the logs, The error not occurs at main manifest file, occurs at /build/intermediates/manifests/full/debug/AndroidManifest.xml
Tried cleaning, rebuilding, disabling instant run. Is there any solution?

You have a misplaced tag. The new AAPT (AAPT2) now throws an error on this.
From the docs in here: https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html
Behavior changes when using AAPT2
To improve incremental resource processing, Android plugin 3.0.0 enables AAPT2 by default. Although AAPT2 should immediately work with older projects, this section describes some behavior changes that you should be aware of.
Element hierarchies in the Android manifest
In previous versions of AAPT, elements nested in incorrect nodes in the Android manifest are either ignored or result in a warning. For example, consider the following sample:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myname.myapplication"> <application ... <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <action android:name="android.intent.action.CUSTOM" /> </activity> </application> </manifest>Previous versions of AAPT would simply ignore the misplaced tag. However, with AAPT2, you get the following error:
AndroidManifest.xml:15: error: unknown element <action> found.To resolve the issue, make sure your manifest elements are nested correctly. For more information, read Manifest file structure.
