Issues during Building Android Source

Hi ,

We are building Android 4.0.1 source code, regarding it we have some query.

1) We are adding a new package in android framework in /base/packages/,
while compiling and building i m getting an error that package "com.xx.xxxxxx not exist"

Do i need to register this new package somewhere in framework?

2) We want to modified System UI , but we seen there is no source code available to modify , in android source code provided for Blaze(Android 4.0.1).

Check attached image: system-ui.png

3) We want to add another lock pattern for device lock/unlock. I added requed constant for new lock option but when I select , it giving me error dialog "unfortunately, Settings has stopped" and error following error log :

"02-25 06:34:56.884: E/AndroidRuntime(697): java.lang.IllegalArgumentException: Invalid quality constant: 0x10

Suggest what I am missing/ doing wrong.

As a first step, ensure that you are pulling in the Android code and building according to the instructions provided in the Release Notes:

http://omappedia.com/wiki/4AI.1.1_OMAP4_Icecream_Sandwich_Release_Notes

After doing this, if there are remaining issues, please provide the steps you are taking to modify AFS, and the error (if any) you get.

Regards,

Magdalena

thaks for reply.

I got answer for first two question, but stl struglling with third one.
I am following same steps which are following for existing Lock screen pattern.

1) First register an constant in DevicePolicyManager.class (0X000050) (avail in . . . /frameworks/base/core/java/android/app/admin/)

2) Keep an else case in onPreferenceTreeClick() of . . /apps/Settings/src/com/android/settings/chooselock generic.java

so here it called savelockpassword(..) method and stored new lock preference .

....so here when I choose it , it respond me above mention error.

pls let me know if anything needful.

thanks

hi,

Seems like you didn't add an extra case to "validateQualityConstant()" function, in ./frameworks/base/services/java/com/android/server/DevicePolicyManagerService.java there is where the exception is been thrown.

regards,

Rodrigo
