AT&T Video Optimizer|Sbowing Error in Android Emulator "Error tcpdump not compiled for this device"

Uday, 

I just attempted the same - and it ran for me.

Here are my emulator settings:

If you are on a PC - is winpcap installed?

Uday, 

So the issue is with your computer?  Where do you see:

4) next getting error like this "Error tcpdump not compiled for this device".

Is that inside the emulator? Or inside ARO?  If inside ARO - do you have winpcap on your windows machine installed?

Hi dougs,

whenver you are free let me know..I'l share what I am following..

Thanks in advance!!

Thanks & regards,

 Hi dougs,

I have downloaded both ARO Data Collector,AROAnalyzer for my windows 7-32 bit operating system.

1) with help of ARO Data Collector collected  data from an application

2) Using the Data Analyzer  It taken the trace data collected from your app..now its working fine for me & showing diagnostics also.

I have one doubt here..

from Diagnostic & rest of tabs how can i analyze the App how much Battery consumption, how long it wil taking to responce.

can you please give me clear Idea..

Thanks in advance!!

Thanks & regards,

Uday, 

So glad you got ARO working.

Now you have a trace and are looking to understand battery drain.

When I think about battery drain, the biggest culprits on a mobile device are:

1. screen

2. radios (Wi-Fi/cellular/GPS/Bluetooth)

ARO uses a model based on actual data I collected on a phone to collect the power used by your app. On the Best Practices tab, you'll see an entry "Energy Consumed"  This tells you the # of Joules your app used.  

Your phone's battery will have a Wh and V rating.

Wh*V*3600 = joules in the battery

So for a Samsung S4:

9.88 * 3.8*3600 = 135,158J, or 135 KJ

If your trace used 2,000J  that's 1.5% of the battery.

To improve that number:

Reduce the number of connections. the less the radio is on - the more power you'll save.  TCP Control bursts are caused by CONNECTION_CLOSE packets. The connections are closed several seconds later - but the radio timers are reset.  Close the connections right away.

look at the documentation in the ARO section of this site for more ideas.

Hi Dougs,

I have collected data of Application Using AT&T ARO  Data Collector.

• Launched AT&T ARO 'Data Collector' and click 'Start Collector'.
• Click 'Hide Collector', opened application in the Emulator, and begin testing.
• When finished testing, go back to AT&T ARO and click 'Stop Collector'. Click 'OK' to complete collecting the trace.

Next 

Launched "AT&T ARO 'Data Analyzer'" click on Open Trace from my local computer (where I have saved path of TraceFiles).

Navigated to "Waterfall" tab  then showing my PC files Name,Applications (it is capturing PC applications)  & as well capuring emaultor also (we want to capture Emulator Application what we are running 

please find below URL to look at Screen

Thanks in Advance!!

Uday, 

When testing on the emulator, you do not need to use the apk.

The emulator is by default rooted, and the "Start collector" on the ARO analyzer will record the traffic right on the emulator. See the docs for details:

http://developer.att.com/application-resource-optimizer/docs#testing-android-emulator

If you are using the collector APK on the emultaor, I bet it *is* collecting all of the traffic on the device.  I think it reads all of the data transmitted over the interface.  Since the emulator interface is also the PC interface - you are seeing PC traffic as well.

Try the above procedure, and see fi it works.

So how did you solve this?
