Android(安卓)Camera ShutterSound customization

You can turn off your camera shutter sound according the steps if you can modify the code.If you have any good ideas ,please contact me.Thanks.

Platform version:4.0

Modify the CameraService.cpp via frameworks/base/services/camera/libcameraservice/ path.

You should find the function these:

1.mCameraService->playSound(SOUND_RECORDING)2.mCameraService->playSound(SOUND_SHUTTER)3.playRecordingSound()

If your SDMID is Shutter_sound_enable, which is from your customization configuration file,you can get the property value of Shutter_sound_enable,like this:

         char value[PROPERTY_VALUE_MAX];         property_get("Shutter_sound_enable",value,"0");         if (strcmp(value,"true")==0){  //if the parameter have two values:true and false                      //enable the shutter sound         }

You should replace all of the 3 functions in the CameraService.cpp.

Then compile the module ,you will get the libcamearaservice.so file,and then push into the phone.

Restart your phone.

You can use the command:

adb shell setprop Shutter_sound_enable false //set the property value

adb shell getprop Shutter_sound_enable //get the property value

I have done the work.

Good luck.
