Re: is there any way to print log in webkit native code ?
printing to the console will probably not work unless your code is running as root. Android provides an easy way of obtaining logs through logcat. The following are the changes that would be required to get logs on native code: (1) Include the header file utils/Log.h #include utils/Log.h (2) Define the logger tag LOG_TAG #undef LOG_TAG #define LOG_TAG MyWebKitLog (3) Write the log statement LOGE(This is my log statement on line %d,__LINE__); (4) If not already done, add libutils and libcutils to the list of LOCAL_SHARED_LIBRARIES in the webkit Android.mk. Note: Similar to LOGE, there are other logger definitions as well, like, LOGV, LOGI, LOGW, LOGF, LOGS, etc. For details about the implementation and usage, please refer the logcat module at http://android.git.kernel.org/?p=platform/system/core.git;a=blob;f=logcat/logcat.cpp;h=d9ca131b64fcc3d1774068dcf6a5e34d05782a3f;hb=master -Ravi On Mar 16, 12:35 am, vincent Kor kor.vinc...@gmail.com wrote: Could you please help to explain in more detail ?

Re: Threading priority in Open MAX components.
The OMX components are tied to the OMX core. It is the core responsibility to either launch a separate thread (and also assign the thread priority) or run them in the same thread. For the OpenCORE framework, i.e., the PV OMX core, currently, there is no way to explicitly mention the thread priority for individual omx components. -Ravi On Mar 16, 6:52 am, Varma varma@gmail.com wrote: In Android, who will decide the threading priority for the OpenMax components which are not there in the Android frame work and where is this threading priority set.

Re: About threads in a service process
Unless otherwise specified, all binder calls are synchronous to the
calling process (usually referred to as the client process). They are
completely asynchronous to the callee (usually referred to as the
server process).
What this means is that the caller will block in the binder call until
the server thread has completed the requested action. On the server
side, the binder request is picked up by on the worker threads, it
proceeds serially until the work is complete, and then returns the
result to the caller across the binder. It is possible for multiple
worker threads to be concurrent within the server process acting on
behalf of different clients, and perhaps even different threads of the
same client.

The way I understand it, atleast through the logs, all IPC calls

Re: InputMethodService (SoftKeyboard)
Sorry I really don't understand what you are doing. InputMethodService.onKeyDown() and InputMethodService.onKeyUp() are called for every single key event being sent to the application, before it does its normal event dispatching. You don't need to do anything special to see them. On Mon, Mar 16, 2009 at 8:02 AM, Daniel daniel.himmel...@googlemail.comwrote: Hi, I now hooked my key processing into onKeyDown of class SoftKeyboard instead of class InputMethodService. SoftKeyboard filtered KeyEvent.KEYCODE_ENTER events before ;-) The only problem now is that I always absorb DPAD_LEFT, DPAD_RIGHT, DPAD_UP, DPAD_DOWN, DPAD_CENTER and KEYCODE_ENTER after the soft keyboard was visible once. A quick fix to this issue is to declare mShowInputRequested as protected and also check this variable in class SoftKeyboard before doing the processing. Here a public method is needed to decide if these key events should be processed by SoftKeyboard. Method isInputViewShown() of class InputMethodService didn't do the job. Or even better, SoftKeyboard's onKeyDown and onKeyUp methods are only called when the SoftKeyboard is visible.

Now we can control the SoftKeyboard with these keys. The problem is that we do not get DPAD_CENTER as this key event is already consumed by the focused text box when writing. Sure, this is exactly what you want if you control the soft keyboard by touch but there should be a way to tell InputMethodService to consume all key events before the underlieing activity can do so. Currently its the other way round I think. We need the DPAD_CENTER key to press the selected key (at the moment we do this with the menu button, but this is ugly).

Clarification about system images
Hi I just posted this in Android Platforms groups but wasn't sure where it belonged so posting it here again. I have this question about the system.img files that come as a part of the standard android SDK (any release but i run 1.1) and the ones that are generated by doing a make in the source code. I find these are different for example the DevTools is not a part of the standard SDK system image but it is available in the image that you get after you build from source downloaded.why is this difference there ? Secondly if i want to include any other packages (for eg i would like to get back the Api Demos which has disappeared in recent releases) what are the steps i should do ? Like i was trying a rough attempt to just compile back Api Demos from a previous version and just did a adb install apidemos.apk and it complained about MISSING SHARED LIBRARIES. what should i do to make sure this works fine ?

Vibrator device in emulator
Hi I am trying to simulate a vibrator device in the emulator
The timed_output class driver is in place and is verified to work
( did a echo 1000 to /sys/class/timed_output/vibrator/enable to the
device and it has been verified to work ).
--- I wanted to invoke this device node from a app and was planning on
using Morsecode from Api Demos ,since it has gone missing in recent
releases wrote just a couple of lines of code to basically call the
vibrator device from an stand alone app.
--- This does not seem to work ,when i ran logcat these are the
sequence of logs passed as the application is being run from the menu
I/ActivityManager( 589): Starting activity: Intent
{ action=android.intent.acti
on.MAIN categories={android.intent.category.LAUNCHER} flags=0x1020
comp={com.x.ui/com.x.ui.uiSimpleWidet} }

I/jdwp( 791): received file descriptor 30 from ADB
D/dalvikvm( 679): GC freed 456 objects / 22176 bytes in 110ms
This is what i see . But the device node is not being called .The app
is pretty simple and just calls the vibrator.vibrate(1) for 10s (i
have also set the permission fine for VIBRATE).I am not able to see
any logs beyond the BinderProxy.I was hoping to see Harware
service.java kick in and take it from there.
Can some one tell me if i am missing any link between the manager and
HAL ? I also made sure hardware service is running by doing a service
list and also made sure libhardware.so and libhardware_logacy.so is
there .
Thanks

Re: Why RIL uses Local socket instead of binder ipc?
Basically because that is how it was implemented. *shrug* And it was written long before there was any Binder IPC facility.

Tools to Check Memory Leak
Hi, Can anyone please suggest any tools to check memory leaks in Opencore source code. Can we check memory leaks with Valgrind tool?
