What is the Android Codes to record accelerometer data?

What device to record or monitor DATA USAGE while running internet.?

• I have no choice but to trust what the internet provider told me what the monthly DATA USAGE that I used. Is there a device I can hook it between the enternet cable and computer enternet socket to check the UP & DOWN DATA rate? Just like I use a current meter to monitor the current, a frequency counter to check the frequency,a scope to see the data waveform. I studied the RS232 feature and the enternet cable structure. I knew which pins to check the TX and RX DATA waveform and frequency (same as bit rate). But there must have a simple device to show directly the DATA speed and usage like most internet provider monitor to its every user's DATA USAGE. I do not want to be fooled by the internet provider that charged extra fee for exceeding data usage . Or I do not want any malware website running in my computer to upload my data without my acknowledgement.

• Answer:

  i don't know such hardware but i m knowing one software which will tell you about data usage and will show which applications are downloading/uploading data from internet. Download Iobit advanced systemcare, it is having utility named as network monitor. This will count data usage and app using internet
