So far the microdump_writer dumped the log in logcat using the default
system log. This is simple to achieve but has some drawbacks:
1. Creates spam in the system log, pushing back other eventual useful
messages.
2. There is a high chance that the microdump gets lost if some log
spam storm happens immediately after a crash and before the log
is collected by the feedback client.
3. Since Android L, the logger is smartly throttling messages (to
reduce logcat spam). Throttling brekpad logs defeats the all
point of microdumps.
This change is conceptually very simple. Replace the use of
__android_log_write() with __android_log_buf_write(), which takes
an extra bufID argument. The main drawback is that the
__android_log_buf_write is not exported in the NDK and needs to be
dynamically looked up via dlsym.
This choice has been discussed and advocated by Android owners.
See the internal bug b/21753476.

To request change review:
0. Get access to a read-write copy of source.
Owners at http://code.google.com/p/google-breakpad/ are able to grant
this access.
1. Check out a read-write copy of source using instructions at
http://code.google.com/p/google-breakpad/source/checkout
2. Make changes. Build and test your changes.
For core code like processor use methods above.
For linux/mac/windows, there are test targets in each project file.
3. Download http://codereview.appspot.com/static/upload.py
4. Run upload.py from the 'src' directory:
upload.py --server=codereview.chromium.org
You will be prompted for credential and a description.
5. At http://breakpad.appspot.com you'll find your issue listed; click on it,
and select Publish+Mail, and enter in the code reviewer and CC
google-breakpad-dev@googlegroups.com
6. When applying code review feedback, specify the '-i' option when running
upload.py again and pass the issue number so it updates the existing issue,
rather than creating a new one.
Be sure to rerun upload.py from the same directory as you did for previous
uploads to allow for proper diff calculations.
