Question

So I almost always get some message like this when I’m compiling my android app:

[javac] Note: /home/kurtis/sandbox/udj/androidApp/src/org/klnusbaum/udj/PlaylistFragment.java uses or overrides a deprecated API.
[javac] Note: Recompile with -Xlint:deprecation for details.

How do I recompile with this option? Do I have to edit something in my build.xml?

Answer 1

Yes, per the statement below in the build.xml file, if you want to …

         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <setup/> task.
             - customize it to your needs.

That means:

1. Go to the $ANDROID_SDK_ROOT/tools/ant/main_rules.xml file and copy the “compile” target.

2. Paste it into your build.xml file before the <setup/> task.

3. Then add the following element to the task:

   <compilerarg value="-Xlint:deprecation"/>
   

4. Likewise, you can add other compiler options, such as for unchecked operations:

   <compilerarg value="-Xlint:unchecked"/>
