Error involving subprocess.py while building Android for a RK3066 device

I get an error when building Android from source which I have not tinkered with and it should really by all means work (I'm quite certain I've got all the libs installed, Java and Python in the correct version). Error messages go as follows:

> Traceback (most recent call last):
  File "../../base/android/jni_generator/jni_generator.py", line 1065, in <module>
    sys.exit(main(sys.argv))

    options.optimize_generation)

make: *** [out/target/product/rk3066/obj/GYP/shared_intermediates/ui/gl/jni/Surface_jni.h] Error 1

I'm not really a specialist, so maybe the information I have provided is not complete. In this case - let me know.

Solution

At line 507 in file external/chromium_org/base/android/jni_generator/jni_generator.py

   p = subprocess.Popen(args=['javap', class_name], 
                     cwd=os.path.dirname(class_file), 
                     stdout=subprocess.PIPE, 
                     stderr=subprocess.PIPE)

It seems you don't have javap available in your PATH

If you have installed the jdk1.6.0_45 in usr/lib/jvm, then you can run this command

  sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jvm/jdk1.6.0_45/bin/javap 1
