I tried this Eclipse and work fine:
Eclipse Classic
//www.filehippo.com/download_eclipse_classic_32/

Eclipse Juno
Eclipse Helios

//developer.android.com/tools/sdk/eclipse-adt.html

android:autoLink="all"

 <!-- text1 automatically linkifies things like URLs and phone numbers. -->
  <TextView
            android:id="@+id/text1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:autoLink="all"
            android:text="@string/link_text_auto"
            />

If I trying
android-sdk_r22.6.2-windows.zip
adt-bundle-windows-x86_64-20140321.zip
and open xml layout graphic editor and xml layout file
memory continues to grow to crashes Eclipse

https://developer.android.com/sdk/index.html

I have to install old version adt-bundle-windows-x86-20131030.zip
what working fine.
I had to delete .metadata folder in workspace if I want open old version ADT

The source attachment does not contain the source for the file TextWatcher.class.
You can change the source attachment by clicking Change Attached Source below:

You have to add JDK src.zip path to dialog as on image below.
[caption id="attachment_1091" align="alignleft" width="282" caption="class file editor source not found Eclipse warning"][/caption]

Or go to Project > Properties > Java Build Path > Libraries
Expand JRE System Library. Expand rt.jar.
Select Source attachment and double click or Edit.
Type path the source code file (External File…) and press OK.

[caption id="attachment_1094" align="alignleft" width="300" caption="Java project build path"][/caption]

Or type path in Java JRE definition

[caption id="attachment_1105" align="alignleft" width="300" caption="Java JRE deifiniton path in Eclipse"][/caption]

How open String.class or others keywords definition with Eclipse.

Now if mouse move about keywords String or F3 on keywords and press button in yellow field will opened String.class
