android - Facebook SDK 4.8.2 导入 ECLIPSE

Question

如何在 Eclipse 中导入 facebook sdk 4.8.2。当我们直接下载开发者网站时，我无法导入，因为 facebook 文件夹包含 aar 文件。并且从 git 中，无法获取 facebook 的 src 文件

Answer 1

这里有 Android Facebook SDK 4 in Eclipse 的回答

I also have faced this problem, so I will write a short guide, how to install it in Eclipse.

Step 1. Import to Eclipse

First of all, download the latest version of SDK (on current moment it is 4.0). Unzip it to a folder.

Open Eclipse, click the right mouse button in "PackageExplorer" and choose "Import". After that, go to "Android" -> "Existing Android Code Into Workspace".

Now click "Browse" and choose unzipped SDK folder, and deselect all other found projects, except from the "facebook" (it is an SDK). Other included projects are just samples, and you don't need them now.

You may select "copy project to workspace" checkbox, if you need this.

Step 2. Fixing errors

After importing, we will see, that the whole facebook SDK package are in errors:

But if we look closer, and open one of marked as error classes, we will find, that SDK tried to importsupport.v4 library:

It required for properly compilation. You can find instructions how to download it using Android SDK Managerhere.

After it downloading, you can find it in your Android sdk folder: <sdk>/extras/android/support/v4. Then add it to the facebook SDK project: right mouse click on SDK project -> "Properties" -> "Java Build Path" -> "Libraries" -> "Add External JARs", and choose android-support-v4.jar from it's folder.

After that a lot of errors will be gone:

But, there are other errors. So we are going to another class, and found it error code piece. Move mouse pointer on it, and Eclipse will show you the hint, of what kind of error you are facing. It says that your compliance Java must be version 1.7. Allow Eclipse do it by clicking "Change project ...", or do it manually by going to "Properties" -> "Java Complier" -> "Compiler compilance level" -> "1.7".

OR

Moving ahead. Now we are facing only one kind of error, that says that the FB SDK can't find required Bolts Android library.

We are going to google, found it compiled jar in a repository. Choose the latest version (for current moment it's 1.2.0, but SDK gradle file is using 1.1.4, so you may choose that), and download the jar. Now add it to the facebook SDK as external lib, as we do it before.

Voila! Ther are no errors anymore!

Also don't forget to set in the facebook SDK project "Properties" -> "Android", that it is a Library.

Just for ensurance, close/re-open the SDK project and clean it ("Eclipse menu" -> "Project" -> "Clean"), so all files can build properly.

Step 3. Add it to the Android project

Now you can try to add it to your Android app. Go to your Android app project "Properties" -> "Android" -> "Library" -> "Add", and choose facebook SDK.

Follow official tutorial, and set up your Android application project (don't forget to add all required elements to Manifest.xml). Than you can use this tutorial to add LoginButton to your Activity. Try to build it. It should run without problem.

编辑:正如您在下面的评论中看到的那样，这个答案尚未得到纠正。处理这个问题的最好方法是将项目从 Eclipse 导出到 Android Studio ，它没有这个问题，并成为第一个 Android 开发工具，其中 Eclipse 似乎像 Android Dev Summit 2015 上所说的那样真正被弃用了。
