Errors running builder 'Android Resource Manager' on project 'Demo'.
java.lang.NullPointerException
2.android INSTALL_FAILED_UPDATE_INCOMPATIBLE
Reason:Usually it's due to having a signed release version on my phone, then trying to deploy the debug version on top. It gets stuck in an invalid state where it's not fully uninstalled.
Resolved:adb uninstall [-k] <package> - remove this app package from the device('-k' means keep the data and cache directories)
3.java.lang.SecurityException: Permission Denial: starting Intent {xxx}from ProcessRecord{xxx} not exported from uid
