[Android] Compile module

Android 模組編譯(mm, mmm)

Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:

- croot: Changes directory to the top of the tree.
- m: Makes from the top of the tree.
- mm: Builds all of the modules in the current directory.
- mmm: Builds all of the modules in the supplied directories.
- cgrep: Greps on all local C/C++ files.
- hgrep: Greps on all local C/C++ header files.
- jgrep: Greps on all local Java files.
- mkgrep: Greps on all local make files.
- rcgrep: Greps on all local .rc files.
- resgrep: Greps on all local res/*.xml files.
- shgrep: Greps on all local .sh files.
- godir: Go to the directory containing a file.

We can use mm/mmm to compile modules, don't need to build the whole system.

[Android] StrictMode

New Gingerbread API: StrictMode

StrictMode is a new API in Gingerbread which primarily lets you set a policy on a thread declaring what you’re not allowed to do on that thread, and what the penalty is if you violate the policy. Implementation-wise, this policy is simply a thread-local integer bitmask.

By default everything is allowed and it won’t get in your way unless you want it to. The flags you can enable in the thread policy include:

detect disk writes
detect disk reads
detect network usage

on a violation: log
on a violation: crash
on a violation: dropbox
on a violation: show an annoying dialog

Watching StrictMode

If you’re using penaltyLog(), the default, just run adb logcat and watch the terminal output. Any violations will be logged to your console, slightly rate-limited for duplicate elimination.

If you want to get fancier, turn on penaltyDropbox() and they’ll be written to the DropBoxManager, where you can extract them later with

adb shell dumpsys dropbox data_app_strictmode --print

SystemServer Thread

When boot up, SystemServer Thread will enable StrictMode for debug purpose (if it is not a user build).
And any violations will be logged to dropbox.

[Patent] Samsung countersues Apple for patent violations

Relative articles:
Samsung countersues Apple for patent violations
Samsung files additional patent lawsuits against Apple in California
Samsung now countersuing Apple in four countries on three continents

What is seemingly unusual is that Samsung didn’t file the lawsuit in America, but instead filed lawsuits in Seoul, South Korea (5 patent infringements), Tokyo, Japan (2 patent infringements), and in Manheim, Germany (3 patent infringements).

The first seven patents are related to communications standards such as W-CDMA (UMTS) while the other three patents are user interface patents.
