Answer 1

You can write a wrapper class that fetches the whole content and returns that data with delays and only in small chunks.

Answer 2

You can use followed 2 applications for your purposes:

• Use Connectify application to create virtual WiFi AP on your PC. Connectify link It will give you ability to manage traffic over virtual adapter.
• Download DummyNet open source program and install service to your virtual AP dowload dummynet

Now you can connect with android to your virtual WiFi AP and manage BW + packet loss + latency by using some scripts (single batch file *.bat). Here is example:

cd C:\ipfw3-2012\binary
@echo on
@set CYGWIN=nodosfilewarning

@ipfw -q flush
@ipfw -q pipe flush

set download="80Kbit/s"

set srcIp=111.111.222.222

ipfw pipe 1 config bw %download%

ipfw add pipe 1 tcp from any to any in

ipfw -c show
ipfw pipe show

It works great. Here is print screen:

Within the Android emulator, you can now throttle the network speed directly.

Press the 3 dots button, followed by 'Cellular' on the left. You can then select the network type and signal strength.

Speeds for reference in increasing kbps:

                        UP       DOWN
                  -------- ----------
gsm   GSM/CSD         14.4       14.4
hscsd HSCSD           14.4       57.6
gprs  GPRS            28.8       57.6
umts  UMTS/3G        384.0      384.0
edge  EDGE/EGPRS     473.6      473.6
hsdpa HSDPA         5760.0   13,980.0
lte   LTE         58,000.0  173,000.0
evdo  EVDO        75,000.0  280,000.0
full  No limit           ∞          ∞

Answer 4

I solved the problem by slowing down the network of my PC with network simulator. Then I created a virtual wifi with win 7 and connected my phone with it.

Answer 5

If your developing on OS X, you can use Network Link Conditioner to slow down your internet connection, then turn on internet sharing and connect the Android phone to that network.
