I want to read a local text file on my computer on an Android Emulator

How can I put that file in userdata.img so that the emulator can read it? Also, how can 开发者_运维百科to specifiy the path of the file in the code? I am using Windows 7.

To push a file onto the emulator or any other rooted device you'd just issue a adb push command.

adb push FILE PATH_ON_DEVICE

You can use adb to push the file to whatever location you want. Just start the emulator (without any device connected) and type

adb push myfile /mylocation/myfile

Alternatively, you can browse the file system using ddms
