"appcompat_v7" project is created automatically after creating a new project in Eclipse
提问by Ali
After creating any new android project, Eclipse automatically creates a "appcompat_v7" project without any files under /src. I have no idea how or why Eclipse is creating this project. I am also getting a weird error.
创建任何新的 android 项目后，Eclipse 会自动创建一个“appcompat_v7”项目，/src 下没有任何文件。我不知道 Eclipse 如何或为什么创建这个项目。我也收到一个奇怪的错误。
As you can see the AndroidManifest.xml exists in the project!
如您所见，项目中存在 AndroidManifest.xml！
EDIT1: After cleaning the project the weird error was gone, but I'd still like to know why the appcompat_v7 is created.
EDIT1：清理项目后，奇怪的错误消失了，但我仍然想知道为什么会创建 appcompat_v7。
EDIT2: I also noticed that Eclipse is automatically creating a new layout, fragment_main.xml, under /res/layout. WHY??
EDIT2：我还注意到 Eclipse 会在 /res/layout 下自动创建一个新布局 fragment_main.xml。为什么？？
I have created a new Workspace, and tried it several times. But I still have this problem.
我创建了一个新的工作区，并尝试了几次。但我仍然有这个问题。
EDIT3: If you choose the minimum SDK version after API 14 you won't get this support folder.
EDIT3：如果您选择 API 14 之后的最低 SDK 版本，您将不会获得此支持文件夹。

I ran into this problem last night. I was doing several things including updating the SDK manager. I had to back off the Android SDK Toolsto Rev. 22.3 and Android SDK Platform-toolsto 19.
我昨晚遇到了这个问题。我做了几件事，包括更新 SDK 管理器。我不得不将Android SDK 工具退回到 Rev. 22.3，将Android SDK Platform-tools退回到 19。

Do as follows to overcome this issue, this works for me. Create project as usual than follow below steps
执行以下操作来克服这个问题，这对我有用。照常创建项目，而不是按照以下步骤操作
Step-1:
Right Click on your Project -> Properties -> Android -> In Library panel, removeappcompat_v7 library, Apply and Ok
右键单击您的项目 -> 属性 -> Android -> 在库面板中，删除appcompat_v7 库，应用并确定
Step-2:
In Project goto res -> values -> style.xml
在项目中转到 res -> values -> style.xml
In line <style name="AppBaseTheme" parent="Theme.AppCompat.Light">changeparent value from Theme.AppCompat.Lightto android:Theme.Light
在线<style name="AppBaseTheme" parent="Theme.AppCompat.Light">更改父值从Theme.AppCompat.Light到android:Theme.Light
Step-3:
In Project goto res -> values-v11 -> style.xml
在项目中转到 res -> values-v11 -> style.xml
In line <style name="AppBaseTheme" parent="Theme.AppCompat.Light">changeparent value from Theme.AppCompat.Lightto android:Theme.Holo.Light
在线<style name="AppBaseTheme" parent="Theme.AppCompat.Light">更改父值从Theme.AppCompat.Light到android:Theme.Holo.Light
Step-4:
In Project goto res -> values-v14 -> style.xml
在项目中转到 res -> values-v14 -> style.xml
In line <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">changeparent value from Theme.AppCompat.Light.DarkActionBarto android:Theme.Holo.Light.DarkActionBar
在线<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">更改父值从Theme.AppCompat.Light.DarkActionBar到android:Theme.Holo.Light.DarkActionBar
Step-5:
In Project goto menu -> main.xml removethese lines in menu tag:
在 Project goto menu -> main.xml 中删除menu 标签中的这些行：
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.test.MainActivity"
and in item tag changethis line from app:showAsAction="never"to android:showAsAction="never"
并在项目标签中将此行从更改app:showAsAction="never"为android:showAsAction="never"
In project, goto res -> layout -> delete fragment.xml
在项目中，转到 res -> layout -> delete fragment.xml
Step-6:
In MainActivity extends Activitynot ActionBarActivity and finally your MainActivity.java after remove unnecessary code, looks like this:
在 MainActivity 中扩展 Activity而不是 ActionBarActivity ，最后你的 MainActivity.java 在删除不必要的代码后，看起来像这样：
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Enjoy:)
享受：）

import the android project to the workspace from /extras/android/support/ then navigate to your current project and add it as dependency : Project > Properties > Android > Add (the imported project) . You should be able to see a Green tick next to the imported project. Remove the old reference that you lost/deleted. A reference about what this library is can be found here
将 android 项目从 /extras/android/support/ 导入到工作区，然后导航到您当前的项目并将其添加为依赖项：Project > Properties > Android > Add (theimported project)。您应该能够在导入的项目旁边看到一个绿色勾号。删除您丢失/删除的旧参考。可以在此处找到有关此库内容的参考
