These steps set up a PPP connection between an Android device and your Linux PC, so that the device can use the Internet connection of the PC. To share an Internet connection the other way around, reverse the roles of the PC and the device.

There's no UI for setting proxy for Android browser. You set a proxy by directly manipulating the settings db:
$ android-sdk-linux_86/platform-tools/adb shell
...
where wifi_http_proxy is the proxy host name and wifi_http_proxy is the proxy port number.

When you run automated Android tests with Eclipse or from the command line, you get text output, which isn't good for reporting purposes. If you run a large set of test cases with automated build, the text report isn't very helpful. Fortunately, Android CTS generates test reports in XML with accompanying XSL to make it look nice in a browser. To run your own tests with Android CTS: Download Android CTS Make a new directory MyRepository under android-cts , alongside the existing repository directory. Copy host_config.xml from repository to MyRepository Create directory plans under MyRepository , add a test plan ( MyTests.xml ):
<?xml version="1.0" encoding="UTF-8"?> <TestPla... Create directory testcases under MyRepository . Copy TestDeviceSetup.apk from repository/testcases to MyRepository/testcases Under MyRepository/testcases , create a test...
