Error while compiling after doing some changes in the framework files of Android

[Ruhi Sharma]

Hello All,


I have added a log statement in sendTextMessage of /frameworks/opt/telephony/src/java/android/telephony/SmsManager.java file. So after compiling the framework with "make", it gave me error like some deprecated API.
Then I commented out  all the @deprecated statement in  /frameworks/opt/telephony/src/java/android/telephony/gsm/SmsManager.java file. Now make works file after doing "make update-api".

Now I tried changing some other files and after doing "make " it is giving me following errors :

******************************
You have tried to change the API from what has been previously released in
an SDK.  Please fix the errors listed above.
******************************


make: *** [out/target/common/obj/PACKAGING/checkapi-last-timestamp] Error 38
make: *** Waiting for unfinished jobs....
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Even after doing "make update-api" still error is there.
After reverting back the new changes, still error is there

Could anyone please explain why this is happening and what do in this case? My work is strucked because of these errors. Please help me

Thanks in Advance :)

It's telling you what the problem is:  you are not allowed to remove methods and fields that are part of any released public API, even though they are now @deprecated and no longer recommended for use.

The fix is to go back and revert your change that removed all of these official-API methods and fields.
