androiddeveloperlb / apk-parser Goto Github PK

I got this on the sample on Pixel 6 with Android 12.1 beta 3 :

can't parse apk for "android" in: "/system/framework/framework-res.apk" - exception:net.dongliu.apk.parser.exception.ParserException: Unexpected chunk Type: 0x206 isSystemApp?true

There are some similar issues on the original repository that were fixed:
https://github.com/hsiafan/apk-parser/issues?q=Unexpected+chunk+Type

Meaning:

hsiafan/apk-parser#52
hsiafan/apk-parser#54
hsiafan/apk-parser#40
hsiafan/apk-parser#49
hsiafan/apk-parser#66
hsiafan/apk-parser#89
hsiafan/apk-parser#111

It seems the original author told me to ignore some chunk types, such as 0x0204 :
hsiafan/apk-parser#96 (comment)
And that it was ignored by treating it in ChunkType class, treating it as NullHeader in ResourceTableParser class.

The proper solution might be related to looking here:
https://android.googlesource.com/platform/frameworks/base/+/master/libs/androidfw/include/androidfw/ResourceTypes.h

Of course, we could ignore this too. I just hope it won't cause an issue.

Attached the sample APK that is problematic, giving this error:

framework-res.zip

Running the sample, I've found this app that it failed to get its app-name (label) properly :

apk label is different for "com.google.android.networkstack.permissionconfig" on /system/priv-app/NetworkPermissionConfigGoogle/NetworkPermissionConfigGoogle.apk : correct one is: "com.android.server.NetworkPermissionConfig" vs found: "com.google.android.networkstack.permissionconfig"isSystemApp?true

This might be related:

hsiafan/apk-parser#123
hsiafan/apk-parser#99

Attached the problematic APK:

NetworkPermissionConfigGoogle.zip

EDIT: another case:

apk label is different for "com.google.android.gms" on /product/priv-app/PrebuiltGmsCore/PrebuiltGmsCore.apk : correct one is: "Google Play services" vs found: "resourceId:0x7f1a0033"

It became quite large, so I had to split it. Rename "PrebuiltGmsCore.zip" to "PrebuiltGmsCore.zip.001" and "PrebuiltGmsCore2.zip" to "PrebuiltGmsCore.zip.002" , and "PrebuiltGmsCore3.zip" to "PrebuiltGmsCore.zip.003"

PrebuiltGmsCore.zip
PrebuiltGmsCore2.zip
PrebuiltGmsCore3.zip

This is what I get from the sample on Vivo V23:

apk version code is different for "com.android.mms.service" on /system/priv-app/MmsService_T1/MmsService_T1.apk : correct one is: 0 vs found: null isSystemApp?true apk version code is different for "com.vivo.entitlement" on /system/app/Entitlement/Entitlement.apk : correct one is: 0 vs found: null isSystemApp?true apk version code is different for "com.vivo.omacp" on /system/priv-app/Omacp/Omacp.apk : correct one is: 0 vs found: null isSystemApp?true apk version code is different for "com.android.systemui" on /system/priv-app/SystemUI/SystemUI.apk : correct one is: 0 vs found: null isSystemApp?true

APKs:

apks.zip

For SystemUI.apk, it became quite large, so I had to split it. Rename "SystemUI.zip" to "SystemUI.zip.001" and "SystemUI2.zip" to "SystemUI.zip.002", and "SystemUI3.zip" to "SystemUI.zip.003" :
SystemUI.zip
SystemUI2.zip
SystemUI3.zip

Running the sample, I've found these apps that it failed to get their app-icons:

can't get app icon for "com.google.android.flipendo" in: "/system_ext/app/Flipendo/Flipendo.apk" isSystemApp?true
can't get app icon for "com.google.android.permissioncontroller" in: "/apex/com.android.permission/priv-app/GooglePermissionController@M_2022_05/GooglePermissionController.apk" isSystemApp?true
can't get app icon for "com.google.android.packageinstaller" in: "/system/priv-app/GooglePackageInstaller/GooglePackageInstaller.apk" isSystemApp?true

can't get app icon for "com.android.settings" in: "/system_ext/priv-app/SettingsGoogle/SettingsGoogle.apk" isSystemApp?true

Attached some of these problematic APK files :

For SettingsGoogle.apk:

For base.apk , it became quite large, so I had to split it. Rename "base.zip" to "base.zip.001" and "base2.zip" to "base.zip.002":

base.zip

base2.zip
