I am write a demo native app. Yesterday, I can launch the app on emulator successfully. Today, I am add one more .c and .edc file, building action is correct, but when try to “Run As > Tizen Native Application” on emulator, I got below error message:

Cannot remove application.

Error code: PACKAGE_NOT_FOUND
Error message: 
Command: /usr/bin/pkgcmd -q -u -t tpk -n org.tizen.myweixin
Management: Check package components in Project Explorer.

Is there anybody encounter such issue?
