Use adb in path by default

[meizon]

Describe the bug
adb must be passed to bundletool, is it possible that it could use the adb executable in my path.

Bundletool version(s) affected
Version: 0.6.0

Stacktrace
[BT:0.6.0] Error: Unable to determine the location of ADB. Please set the --adb flag or define ANDROID_HOME environment variable.

To Reproduce
Use bundletool without providing an adb

Expected behavior
It would default to the adb on my path

Environment:
OS: Linux

Could you set the environment variable ANDROID_HOME with the path to the SDK? Then, bundletool would be able to find adb in it.

@plecesne it's common for our team (WebView and Chrome for Android) to use the adb binary in the $PATH (e.g., sudo apt-get install adb).

@plecesne would you be open to a pull request for this feature?

Is there a simpler way to resolve this ANDROID_HOME path error?

For instance, I'm attempting to use Android's bundletool but am receiving the error:

Unable to determine the location of ADB. Please set the --adb flag or define ANDROID_HOME environment variable.

Attempted Command

bundletool-all-0.6.0.jar build-apks --bundle=/path/app.aab --output=/path/app.apks --ks=/path/coinverse-release.jks --ks-pass=file:/path/keyname.pwd --ks-key-alias="appname-release" --key-pass=file:/path/keystores/key.pwd --connected-device

Current Solution
By defining the ANDROID_HOME path in my .bash_profile for my Macbook Pro resolved the issue as described in this Stackoverflow post.

1. cd ~
2. ls -a (look to make sure .bash_profile is in the folder you are in)
3. vi .bash_profile
4. Add the following lines:
   export ANDROID_HOME={androidSdkPath} (ie: /Users/adamhurwitz/Library/Android/sdk/)
   export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Note: When attempting to use --adb in the path it does not work with the following error.
