Resolves an android project under Eclipse cannot automatically generate a R.java file

Typically, the R.java file is generated automatically when the project is established. However, when you do development under eclipse, you occasionally encounter R.java files that cannot be generated automatically. Now it's time to solve the problem.

The version of the 1.eclipse ADT plugin does not correspond to the Android SDK version

The general problem arises here, as long as the ADT plugin and SDK are updated to the latest, restarting Eclipse is OK.

The red box has to be all install to the latest.

2.eclipse own problem (and you are uncomfortable, haha)

So you clean up your project, or use the Android tool to fix it. The R.java file is back.
