Android screencast written in QT. There is one in java? forget it from now on.
A tool used to view a mirror screen of your Android device on the PC, show a demonstration, debugging and so on. You can even click on the mirrored screen just as you touch on the device panel.

Minor:
Not a feature yet:
You can press F1/2/3/4 on your keyboard to emulate the following Android key.
For device:
F1 AKEYCODE_HOME
F2 AKEYCODE_BACK
F3 AKEYCODE_CALL
F4 AKEYCODE_ENDCALL
For application on PC:
F12 Rotate view window (Landscape/Portrait)
Linux, any distribution with Qt package.
Qt 4.x+ installed in your system
screencap command on the target device
$> adb shell ls /system/bin/screencap
/system/bin/screencap
If the output indicates: 'No such file or directory', you can use the tool except install one by yourself.
the 'screencap' source code is present in frameworks/base/cmds/screencap.
PC: adb command is availible in your search path, check it:
$> which adb
/usr/bin/adb
USB cable connected to your Android device
Android device in engineer mode (rooted), So that you can get root permission in ADB shell
$> adb root
$> adb shell id
uid=0(root) gid=0(root)
minigzip installed on your PC (for compressed image transfer)
There is a precompiled x86_64 minigzip binary in the contirbutes directory, just copy into your system path:
$> sudo cp contributes/minigzip /usr/bin
If you want to compile one for yourself, get it from android/external/zlib:
$> cp -rf android/external/zlib zlib-pc
$> cd zlib-pc
$> ./configure
$> make
$> sudo cp minigzip /usr/bin
It'll be appreciated If you can help add the decompression code into this project to help to avoid running external program 'minizip' to decompress frame buffer data.
Reduce screen data size generated by screencap
Currently, we use 'screencap' command on the device to capture the screen content, bigger screen resolution causes more data to be transferred between the device and the host which causes more lag.
I've added two options to the screencap which haven't been adopted by upstream yet. You can apply this patch to your source code to reduce the data size generated by screencap to reduce the transfer lag.
$> cd frameworks/base/cmds/screencap
$> patch -p3 < $PATH_TO_SEVENSQAURE/contributes/0001-Add-option-q-s-for-screencap-L/M/N.patch
$> mm
$> # Push new screencap to your device
The original screencap outputs image in RGBA_8888 format, we add an option to convert it into RGB888/RGB565 to save transfer and compress time, which is already supported by current seven-square.
New options:
-q: quality preferred, will convert to RGB888. - 25% size reduced. -s: speed preferred, will convert to RGB565. - 50% size reduced.
Install dependences and just make:
$> apt-get install qt4-qmake libqt4-dev libqtcore4 libqtgui4
$> make
Run from source tree:
$> ./build/seven-square
System-wide install:
$> make install
Or you can create a shortcut on your desktop.
If you want to support to define more keys in the UI, please read the contributes/generate-keymap.sh for more info.
Q: Can I connect to my device via the network and using seven-square? A: Yes. Just use 'adb connect ...' to connect your device before running seven-square, make sure you can see it via 'adb devices', and you can run 'adb shell ls'
Q: I noticed a lot of lag, can that be fixed? A: Try to follow the guideline in the 'Optional' section, which will help a bit on this issue.
'Seven Square' was a game I played when I was a child, and I wrote a QT version for it, in the branch sevensquare-game, [screenshot]:(screenshots/Screenshot-sq.png). And now it's the base code of this tool.
