Android APK was rejected by Google Play because it's debuggable

[fishy]

Please provide the following information. The more we know about your system and use case, the more easily and likely we can help.

Description of the problem / feature request / question:

I have an android_binary rule, and generated app_unsigned.apk file from the rule.

Then I signed it with my release key per instructions on #1613, as:

bazel build java:app --strategy=AndroidAapt=standalone
zipalign -v -p 4 bazel-bin/java/app_unsigned.apk app-unsigned-aligned.apk
apksigner sign --ks release.jks --out app.apk app-unsigned-aligned.apk
rm app-unsigned-aligned.apk

When I try to publish the generated app.apk file on Google Play, it was rejected as "You uploaded a debuggable APK".

Bazel should provide a way to generate undebuggable APKs.

If possible, provide a minimal example to reproduce the problem:

Environment info

• Operating System:
  macOS 10.12.3

• Bazel version (output of bazel info release):
  release 0.4.4-homebrew

• If bazel info release returns "development version" or "(@non-git)", please tell us what source tree you compiled Bazel from; git commit hash is appreciated (git rev-parse HEAD):

Have you found anything relevant by searching the web? (e.g. GitHub issues, email threads in the bazel-discuss@googlegroups.com archive)

Anything else, information or logs or outputs that would be helpful?

(If they are large, please upload as attachment or provide link).

Adding android:debuggable="false" into the application section in AndroidManifest.xml can workaround this issue, but that means I have to maintain two AndroidManifest.xml files, one for debug and one for release, which is error-prone. Bazel should provide a mechanism to generate release APK.

@ahumesky can you take a look please?

--compilation_mode=opt (or -c opt for short) should set the debuggable flag to false, among other optimizations. We're revamping our android documentation and we'll be sure to mention this.

--compilation_mode=opt did the trick, but -copt doesn't work:

$ bazel build java:app --strategy=AndroidAapt=standalone -copt
Invalid options syntax: -copt

$ bazel build java:app --strategy=AndroidAapt=standalone --copt
Expected value after --copt

[ahumesky]

whoops, that's a typo, there should be a space between -c and opt ("-c opt") (i edited my comment above)

[fishy]

-c opt worked. Thanks!
