I read that Google has stopped supporting Eclipse for Android development. You should probably switch to Android Studio, which just released version 1.0.
From
http://developer.android.com/tools/sdk/eclipse-adt.html:
Note:
If you have been using Eclipse with ADT, be aware that
Android Studio is now the official IDE
for Android, so you should migrate to Android Studio to receive all the
latest IDE updates. For help moving projects,
see
Migrating to Android
Studio.
Other articles said that Google would support Eclipse only until Android Studio version 1.0 was released.
Eclipse was great for a long time, and I still like it for all other Java development.
You might also look at AIDE. An IDE that runs on Android. It can read both eclipse and Android Studio Android projects. Coupled with git or Dropbox, you can have a portable development studio for Android that runs without an emulator - projects run natively on the Android device running AIDE.
