Android 10: `GetService` failed

[1514599514]

I've tried several examples on Android 10, and they all fail at the GetService call.

Below is the error message I encountered when running the package_queryexample.

PS D:\goProject\test_binder> .\build.ps1

get package service: servicemanager: GetService("package"): versionaware: method android.os.IServiceManager.getService not found in version 29.device

I verified via command line that the service is present.

PS D:\goProject\test_binder> adb shell "service list | grep package"

Quick side note: Is it possible to implement a pure Go version of minicap screenshot functionality using this project? The plan is to create a virtual display on Android and capture raw frames from it.

Thank you so much for your hard work—you’ve finally freed Go’s Android Binder calls from cgo dependencies.
