warning: [cast] redundant cast to android
.os .IInterface android .os .IInterface iin = (android .os .IInterface)obj .query Local Interface(DESCRIPTOR); in ISelf Braille Service .java
Reported by Chris Double in bug 876475 comment #32: This patch landing has broken my Android builds: JAR gecko-browser.jar /src/mozilla/android/android/mobile/android/base/braille/com/googlecode/eyesfree/braille/selfbraille/ISelfBrailleService.java:30: warning: [cast] redundant cast to android.os.IInterface android.os.IInterface iin = (android.os.IInterface)obj.queryLocalInterface(DESCRIPTOR); ^ Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details. 1 warning make: *** [jars/gecko-browser.jar] Error 1 Kats added in bug 876475 comment #37: This is likely due to the java compiler version in use. Java 7's compiler is more strict. It would be a good idea to remove the redundant cast pointed out in the warning message.
Chris, what version of the Android SDK do you use? I tried a few of the most recent versions and none of versions of aidl associated with them generated code with that redundant cast.

Java version is: java version "1.6.0_45" Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
The problem occurs because older versions of the aidl tool generate code with the extraneous cast and since we're building with -Werror, this causes the build to fail. After talking with kats on irc, he suggested that we could just check-in a generated file that works.

DO NOT MODIFY. > + * Original file: ISelfBrailleService.aidl Is the .aidl file expected to change? If not, then remove these comments and add the Mozilla license here instead. Also fix up the indenting in this file so that it is readable. Basically we want to treat it like a regular source file. If it is expected to change then just update the comment to note that the aidl file is not in the tree, but since this file is periodically re-generated and hand-modifications will be lost.

I don't think the aidl should change, so I went with the first option. https://hg.mozilla.org/integration/mozilla-inbound/rev/6d6b5492ef06
