you can find here some info about writing correct MakeFiles

http://www.chemie.fu-berlin.de/chemnet/use/info/make/make_4.html

the option i was looking for is how to create depndency between files that exist in other projects.
the solution is to use VPATH in the makefile.

`VPATH`: Search Path for All Dependencies

CCache - speed C++ compiler output

ccache is a compiler cache. It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. Supported languages are C, C++, Objective-C and Objective-C++.

to make it work on aix with xlC_r compiler , i used the next steps:

i download the sources and compile them on aix via g++ compiler
i copied the output ccache program into my build machine.

i set the next environment to make support xlC_r compiler:
export CCACHE_EXTENSION=i (this tell the compiler to generate preprocessor file with i extension)

helper settings FYI:
export CCACHE_DISABLE=1 (to avoid using ccache)
export CCACHE_LOGFILE=/yaniv/ccachelog.log (to see ccache log)

"ToneGenerator " - code that can help how to generate tones

GrepCode: com.android.phone.EmergencyDialer (.java) - Class - Source Code View:

android long press timeout

The default time out is defined by ViewConfiguration.getLongPressTimeout().

You can implement your own long press:

boolean mHasPerformedLongPress;
Runnable mPendingCheckForLongPress;

@Override
public boolean onTouch(final View v, MotionEvent event) {

switch (event.getAction()) {
case MotionEvent.ACTION_UP:

if (!mHasPerformedLongPress) {
// This is a tap, so remove the longpress check
if (mPendingCheckForLongPress != null) {
v.removeCallbacks(mPendingCheckForLongPress);
}
// v.performClick();
}

break;
case MotionEvent.ACTION_DOWN:
if( mPendingCheckForLongPress == null) {
mPendingCheckForLongPress = new Runnable() {
public void run() {
//do your job
}
};
}

mHasPerformedLongPress = false;
v.postDelayed(mPendingCheckForLongPress, ViewConfiguration.getLongPressTimeout());

break;
case MotionEvent.ACTION_MOVE:
final int x = (int) event.getX();
final int y = (int) event.getY();

// Be lenient about moving outside of buttons
int slop = ViewConfiguration.get(v.getContext()).getScaledTouchSlop();
if ((x < 0 - slop) || (x >= v.getWidth() + slop) ||
(y < 0 - slop) || (y >= v.getHeight() + slop)) {

if (mPendingCheckForLongPress != null) {
v. removeCallbacks(mPendingCheckForLongPress);
}
}
break;
default:
return false;
}

return false;
}

View source from odex file

copy the framework directory from the android you get the odex file.

/system/framweork copy to D:\MyStuff\Android\odex_deodex\l5-framework

open cmd - and run the next commnads
cd D:\MyStuff\Android\odex_deodex

java -jar baksmali-2.0.2.jar -d D:\MyStuff\Android\odex_deodex\l5-framework -x d:\temp\YouTube.odex
the generated file go-to out folder by default.

now lets convert the out folder to dex file :
java -jar smali-2.0.2.jar -o classes.dex out

use dex2jar file to create jar file
d2j-dex2jar.bat D:\MyStuff\Android\odex_deodex\classes.dex
this will generate classes-dex2jar.jar

open the jar file via jd-gui program
jd-gui.exe and choose the jar file classes-dex2jar.jar

and you can see the code !!!
