Some problems are often encountered and need to be solved with some instructions. Record them here:
1.INSTALL_FAILED_UPDATE_INCOMPATIBLE
adb uninstall package-name
2. "Android SDK: resolving error markers" keeps appearing in Eclipse
Delete this file, workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi, and restart Eclipse.
