Environment

Confirmed with Mozc 2.17.2287.102 running on Android 6.0.1 MNB29K / Nexus 5 2013.

Possible affected versions are from Mozc 2.17.2264.102 to Mozc 2.17.2287.102.
Probably there is no device/OS version dependency.

Steps to reproduce:

  1. Build Mozc 2.17.2287.102 for Android.
  2. Install Mozc into Android 6.0.1 MMB29K on Nexus 5 2013.
  3. Enable Mozc.
  4. Switch to Mozc.

Expected behavior

Mozc starts working.

Actual behavior

Mozc starts crashing.

Here is the relevant crash log.

Additional Information:

This is a regression accidentally introduced by 9cd4d36. The root cause is that base/base.gyp:jni_proxy GYP target is not linked to libmozc.so unless branding=="GoogleJapaneseInput"

Fix a runtime crash in Mozc for Android.
a86c7d0 
This is a follow up CL for 9cd4d36.

The root cause of the runtime crash is that base/base.gyp:jni_proxy is
not linked to libmozc.so only in OSS build because the link dependency
on 'jni_proxy' target is specified in 'net/net.gyp' only when
branding=="GoogleJapaneseInput".  There are two different problems.

 1. There are direct function invocations of base/android_jni_proxy.cc
    from android/jni/mozcjni.cc.  Hence it's 'android/android.gyp:mozc'
    that should have declared the dependency on 'base/base.gyp:jni_proxy'.
    Declaring the dependency in 'net/net.gyp' does not make much sense.
 2. With CL 96942303, 'base/base.gyp:jni_proxy' needs to be linked to
    libmozc.so even in OSS build.

This CL addresses both of avobe issues.

Closes #345.
