I installed MyEclipse 10.0 and wanted to Install a plug-in. However, I found that no New Software was installed in the Help menu .... Finally, we found that MyEclipse made some modifications, and the method for installing plug-ins is somewhat different from that of the original Eclipse. Click Help-> MyEclipse
Configuration Center, and then click the Software tab. On the right side of the search plug-in input box on the left, there is the Add Site link to Add the plug-in installation address here. After adding the package, you can see it in the Personal Sites below. Expand and double-click the items to be installed. The Pending Changes box on the right will contain the Apply XX Changes button and click to install the package.
The latest ADT official link is here: http://developer.android.com/sdk/installing/installing-adt.html
After downloading the ADT compressed package, decompress the package and install the plug-in according to the above steps. I installed the plug-in online, but I don't know why it failed, we recommend that you download the ADT package and install it locally, as shown in:
Name can be set to androidADT at will. Select add from local folder and select the folder where your ADT is located.
After a while, you can see your installed plug-in personal sites. If you want to uninstall the plug-in, right-click it in My software and choose move.
Click pending changes.
