Regarding the cases when the R class does not get generated/updated in time, try the following (in no particular order):
- Manually delete the R.java class, so the next time it will generate a completely new one. - Right click on the project -> Android Tools -> Fix Project Properties - Clean the project under Project -> Clean - Restart Eclipse Regarding the case when updating the text in the layout did not reflect in the emulator, are you sure the latest project was deployed to the emulator? Can you confirm that the APK is built and pushed to the emulator by looking at the console? Sometimes, the ADB has issues and it disconnects with the emulator. If this was the case, your emulator was still running the previous version.
