APN list is empty on master branch

[AntonyMCs]

Hi,

At some point after android-4.2.2_r1 (I'v tested on it and it's working as expected) the apn list is empty under Settings/Wireless&Networks/More/Mobile Networks/Access Point Names, thus there is no default data connection available. I noticed it both in maguro and mako devices.

/system/etc/apns-conf.xml seem ok.

I can't find any related information around the groups, known-issues or googling around.

Does anyone experienced the same behavior?

Any help would be appreciated,

Tony

This is what I extracted from logs:

Hi,

Although this issue has gone unnoticed, I want to add more information.

I have been digging and found that as of

Change id: Idfa06c6f39a2c15ff4f0815724823f44b76ac819
Change-Id: Ib8e7370ebc99c1518e6d9337621e64966c128a0b

APNs database version have been upgraded to 8, but only the reference xml file (frameworks/base/res/res/xml/apns.xml) have reflected this change, but not the corresponding device/*/*apns*conf*.xml

During my research I found the following files to represent apns lists and greping them i found the listed usages:

./device/generic/goldfish/data/etc/apns-conf_sdk.xml

Not used in any current project.

./device/generic/goldfish/data/etc/apns-conf.xml

./build/target/product/full_base_telephony.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml

./build/target/product/sdk.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml \

./build/target/board/generic/device.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml \

./build/target/board/generic_x86/device.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml \

./build/target/board/vbox_x86/device.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml \

./build/target/board/generic_mips/device.mk: device/generic/goldfish/data/etc/apns-conf.xml:system/etc/apns-conf.xml

./device/samsung/toroplus/test-apns-conf_sprint.xml

./device/samsung/toroplus/full_toroplus.mk:PRODUCT_COPY_FILES := device/samsung/toroplus/test-apns-conf_sprint.xml:system/etc/apns-conf.xml

./device/sample/etc/test-apns-conf_verizon.xml   

Not used in any current project.

./device/sample/etc/apns-conf_verizon.xml

./device/samsung/toro/full_toro.mk:    device/sample/etc/apns-conf_verizon.xml:system/etc/apns-conf.xml \

./device/samsung/toro/device.mk: device/sample/etc/apns-conf_verizon.xml:system/etc/apns-conf.xml \

./device/sample/etc/apns-full-conf.xml

./device/lge/mako/full_mako.mk:PRODUCT_COPY_FILES := device/sample/etc/apns-full-conf.xml:system/etc/apns-conf.xml

./device/samsung/maguro/full_maguro.mk:PRODUCT_COPY_FILES := device/sample/etc/apns-full-conf.xml:system/etc/apns-conf.xml

I'm not sure if the ones that are not used should be upgraded to v8 as well, but in the change I have submitted to fix this bug I have done so because their containing projects are over the change that incremented the DB version.

Currently I can only test it on mako and maguro and now the data connection is working as expected.

 

The changes can be seen in gerrit: https://android-review.googlesource.com/#/q/Iaa63fabf922d222a184849fd8cc72e86dc3d9efa,n,z
