Using the Google Android emulator is a good way to test how a website behaves on Android devices.
Connecting to your local computer
Using a hosts file
The Android emulator will not make use of your local hosts file. This is unfortunate when your website relies on host headers to work correctly (eg. SharePoint). What you need to do is edit the hosts file on the Android emulator image itself.
- start your Android Virtual Device (AVD):
emulator -avd myAvdNameHere -partition-size 128This is located in C:\Program Files (x86)\Android\android-sdk-windows\tools\ on Windows 64bit.Note: The partition-size parameter is needed to expand the image size to prevent an error in step 5. If you try and perform these steps after starting the emulator from the UI you will receive the following error: failed to copy ‘c:\temp\hosts’ to ‘/system/etc/hosts’: Out of memory
- remount the device image as writable:
adb remountThis is located in C:\Program Files (x86)\Android\android-sdk-windows\platform-tools\ on Windows 64bit.
- save a copy of the existing hosts file to a temporary location on your host computer:
adb pull /system/etc/hosts c:\temp
- edit the hosts file adding an entry pointing to your host computer:
127.0.0.1 localhost 10.0.2.2 mytesthost
- save the edited hosts file to your Android emulator:
adb push c:\temp\hosts /system/etcYou can now browse to your entered hostname in the Android browser.
Step by Step Don’t Create the AVD with a Google Play image. Use for example Google APIs Intel x86 Atom System Image. Start the emulator with the following command… emulator.exe –avd <avd name> -writable-system For example: C:\Users\ilyas.mamun\AppData\Local\Android\Sdk\emulator>emulator.exe -avd Pixel_API_25 -writable-system emulator: WARNING: System image is writable HAX is working and emulator runs in fast virt mode. audio: Failed to create voice `goldfish_audio_in' qemu-system-i386.exe: warning: opening audio input failed audio: Failed to create voice `adc' Root and Remount the AVD like the followings… C:\Users\ilyas.mamun\AppData\Local\Android\Sdk\platform-tools>adb root C:\Users\ilyas.mamun\AppData\Local\Android\Sdk\platform-tools>adb remount remount succeeded C:\Users\ilyas.mamun\AppData\Local\Android\Sdk\platform-tools>adb shell eneric_x86:/ # cd system generic_x86:/system # cd etc generic_x86:/system/etc # cat hosts 127.0.0.1 localhost ::1 ip6-localhost generic_x86:/system/etc # echo "192.168.1.120 ilyasmamun.blogspot.com" >> hosts generic_x86:/system/etc # cat hosts 127.0.0.1 localhost ::1 ip6-localhost 192.168.1.120 ilyasmamun.blogspot.com generic_x86:/system/etc #
