How can I change package name and package domain?

[mehdializade]

When I changed package.name = oscservice to package.name = BatteryProtector and package.domain = org.kivy to package.domain = org.ipfelec in buildozer.spec, app don't run. I also changed the following code, the app will not run.

 SERVICE_NAME = u'{packagename}.Service{servicename}'.format(
     packagename=u'org.ipfelec.BatteryProtect',
     servicename=u'Pong'
 )

This is my Error:

Is it possible for me to change these names?

i know this is a bit late, but apparently the format is
u'{packagename}.Service{servicename}
where servicename is actually capitalised only on the first letter. all the others are not .
if it does not work, try checking the AndroidManifest.xml file in the directory
/APP_ROOT_FOLDER/.buildozer/android/platform/build-armeabi-v7a/dists/PACKAGE_NAME__armeabi-v7a/AndroidManifest.xml
Note that this will be generated after at least one build
