The controller of AimDroid

README

This project hosts the implementation of the controller of AimDroid. The internal name of the controller is monidroid

Build

1. Install golang.
   1. Mac OS: brew install go
2. Create the workspace for go following https://golang.org/doc/code.html. The following is a list of simplified steps.
   1. Create the default go workspace at $HOME/go/.
   2. Setup env variable GOPATH: export GOPATH=$HOME/go
   3. Create the default go source code folder at $HOME/go/src.
3. Change directory to $HOME/go/src and clone the source code of Monidroid:
   1. git clone git@github.com:icsnju/AimDroid-controller.git monidroid.
   2. The folder name must be monidroid.
4. Change directory to $HOME/go/src/monidroid and run go build.
5. You will see an executable tool named monidroid at $HOME/go/src/monidroid/

Configuration

Here is a sample of configuration file.

{
    "PackageName":"com.google.android.apps.photos",
    "MainActivity":"com.google.android.apps.photos.home.HomeActivity",
    "SDKPath":"/Users/tianxiaogu/Library/Android/sdk/",
    "Epsilon":0.2,
    "Alpha":0.6,
    "Gamma":0.5,
    "MaxSeqLen":100,
    "MinSeqLen":20,
    "Time":3600
}

Here is the explanation of each option.

1. PackageName: the app name of the app under test.
2. MainActivity: the entry activity of the app.
3. SDKPath: the path to the Android SDK
   • We need to run the command adb to communicate with the phone.
4. Epsilon, Alpha, Gamma: the parameters for the reinforcement learning module. See the paper for more details.
5. MaxSeqLen, MinSeqLen: the length of actions in a single activity. See the paper for more details.
6. Time: the total testing time in seconds.

Emulator

AimDroid was first evaluated on real table devices. We have encountered problems of invoking su -c on the emulator. Apply the following patch if you want to build a version for emulator.

cd $HOME/go/src/monidroid
find . -name "*.go" -exec sed -i "s/su -c//" {} \;
