Use xcode to debug special effects in the project, you need to install glfw before use
brew install glfw
Then use xcode to openlibrary/src/main/cpp/opengl.xcodeprojJust
Switch effect call code
image_process.OnAction("param/blurScreen", 0);
- Use uiautomator2 for automatic testing Use as follows:
cd trinity
python trinity.pyThen use
adb devices
Just enter the device name in the terminal
Note: The permission judgment is not made in the SDK. The caller needs to apply for permission when using it. The time involved in the SDK is milliseconds.
