Sometime the 'Fix Project properties...' is not useful.
I suggest that you can open that file and edit+save it, then delete the 'project.properties' file.
At last you can create a new 'project.properties' file and paste the content of the old 'project.properties' file's content.

That worked for me.

The accepted answer may had the problem solved a few years ago but it doesn't work anymore with the more recent tools.

This is a known bug on Eclipse.

The only way to solve this problem is by creating again a <code>project.properties</code> file, which no one posted how it looks inside so I'll be posting this as an answer:

<pre><code># This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-19
</code></pre>

blocks|key|237669|text|通常，Android+Tools-->Fix+Project+Properties应该可以工作。但这并没有解决我的问题。我刚刚从工作区中删除了项目，并再次导入，没有问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|237670|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|$]]

Generally Android Tools-->Fix Project Properties should work. but it didn't solve my problem. I had just delete project from from workspace and import again second time no problem..

blocks|key|233982|text|如果您正在从文件夹导入新项目，请将此项目作为常规项目导入，而不是Android项目(我不能告诉您原因)。导入后，编辑project.properties文件，只需添加一些字符，然后保存文件。现在Eclipse可以识别project.properties文件了。修复它(删除添加的字符)，现在项目应该可以正常工作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|233983|entityMap^0|1M|I|30|I|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

In case, you are importing new project from file folder, import this project as general project, not as Android project (I can not tell you why). After import, edit <code>project.properties</code> file, just add some character, then save the file. Now Eclipse recognizes <code>project.properties</code> file. Repair it(remove added character) and now the project should work fine.

blocks|key|233970|text|如果从归档文件导入后发生这种情况，我建议删除工作区的项目，然后再次导入。这对我很管用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|233971|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|$]]

If it happens after importing from archive, I suggest to remove the project for the workspace and import it again. That was working for me.

blocks|key|2902137|text|如果项目已经包含文件default.properties，您可以打开该文件并对其执行edit%2Bsave操作(添加空间、保存、删除该空间、保存)。这对我很管用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2902138|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|$]]

If the project already contains a file default.properties you can open that file and edit+save it (add a space, save, remove that space, save). That worked for me.

Right click project -> Properties -> Java Build path -> Order and Export -> check the checkbox of Andorid 4.3.

blocks|key|3116322|text|检查文件编码。显然，UTF-BOM对于Eclipse的任何部分来说都太难了--SDK负责处理project.properties文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3116323|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 file encoding. Apparently UTF-BOM is way too hard for whatever part of Eclipse-SDK is responsible for handling that project.properties file.

blocks|key|237767|text|我也有同样的问题，简单的方法是|type|unstyled|depth|inlineStyleRanges|entityRanges|data|237768|RightClick项目文件-->新建-->文件-->文件名类型文件名为project.properties和-->完成-->在project.propeties文件中键入this+target=android-17(你的android版本)|237769|然后所有的错误都会消失|237770|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

i have same issue, simple way is 

RightClick project file--> new --> file -->filename type file name as project.properties and --> finish --> inside project.propeties file type this target=android-17(your virsion of android)

then all errors go away

I am developing Android app in Eclipse.

Currently, eclipse complains:

<code>"Project has no project.properties file! Edit the project properties to set one."</code>

But I do have <code>project.properties</code> file under my project root folder. Why it complains? 

This problem causes several of the resources in <code>R.java</code> can not be resolved in Activity. 
How to get rid of this problem?

Project has no project.properties file

Android

Eclipse

Java

我正在开发Eclipse中的Android应用程序。目前，eclipse抱怨："Project has no project.properties file! Edit the project properties to set one."但是我在我的项目根目录下有 project.properties文件。为什么它会抱怨？此问题导致无法在Activity中解决R.java中的一些资源。如何摆脱这
