Welcome everyone
In this video, let's see the hidden menu "Developer options" on the Android systems
As you can see in another my video, to active this menu, let's move on "Settings"
Then, you press several time on the item "Build version", until does show the message "The developer options has been activated" ( or something similar )
Now, you can see the menu "Developer options" in the "Setting"
In this menu you can find some options for development, including: The possibility to report system bug ( to active it you can active the USB debugger, that we will see later )
Create an encrypted backup on the pc ( for more informations see the descriptions )
The possibility to keep the display on, during the recharges
The possibility to register the H.C.I packages of the bluetooth ( that are save on the external storage, for more information you can see the descriptions )
All the system process stats ( where if you press on each process, you can see more information on it )
The U.S.B debugger, that it allows to make advanced operations on the system ( Ex: install the programs from the pc, receive more information on the system, and other.. )
The possibility to revocation all the U.S.B permissions
The possibility of to add the menu "Send report of bugs" in power menu
The possibility to send a fake position when you turn the G.P.S on
The possibility to select the program for the CPU debugger ( to useful for development, you can see more details in description )
The possibility to open it when the cable U.S.B is connected
Analyze the applications with ADB / ADT ( that we will see in description )
The possibility to analyze the Wireless Display permissions ( system that allows to transfer videos inside wireless networks )
Show the touch on the screen
Show and track the pointer position ( it positions by the touch on the screen )
The possibility to flash the screen when the the graphics is updated
Show the applications layout ( helpful in development phase ) The possibility of view the applications layout through the R.T.L algorithmic ( Right to left )
If you active this option, everything that you find to right will go to left and everything that you find to left will go to right
Three options to disable or slow down the system animations ( That i already treated in another video, where advice to disable all the animations to improve the system performance )
Simulate secondary screen ( this option is used for change screen resolution through ADB, for more informations look the description )
Use the 2d hardware acceleration in the applications
The possibility to make the screen flash during the GPU processes ( graphics process unit )
the possibility to make flash the hardware level during its update ( You can see more information in the description )
Analyze events of GPU overdraw ( that it occurs when the gpu write the same pixel more times, event not always necessary )
The possibility to highlight the parts not rectangle on the screen
The possibility to use the MSAA functions in game, (anti-aliasing, that we will view more better in description )
Disable overlay of hardware layer ( more informations in description )
The "Strict mode" function, tool that detects durable operations ( Input or output ) on the main process of the application ( available from the version 2.3 of Android )
Show the CPU stats ( showing at the top right on the screen )
The possibility to choose the CPU rendering profile on the screen ( press to choose it )
The possibility to active the Open GL tracks ( function for development )
The possibility to close applications as soon as we leave it
Android is an "User friendly" system, for this, as soon as we leave an applications the system doesn't close it but the leave it in background, ready to be reopened, avoiding initializing application again
Holding the initialize operation in memory ( production of graphic interface, etc.. ) speeding up the applications at a later time ( for this I don't advice to active the function to optimize the system )
The possibility to limit the background applications
Show a dialog box for everything applications that not reply ( where we are offered the possibility to close or not the application )
