Practicing automated phone operations inevitably involves capturing the current image of the phone. The phone’s built-in screenshot is too slow, so replacing it with minicap.
Software Compilation

# Clone the project code and initialize git clone https://github.com/openstf/minicap cd minicap/ git submodule init git submodule update # Compile, ndk is required (archlinuxcn source has it, just install directly) sudo pacman -S android-ndk # Compile, after installation, it won't be added to bin automatically, so run with absolute path /opt/android-ndk/ndk-build
Software Deployment to Phone

# To use adb connect to the device, if not installed first install adb # manjaro community has it, I remember the official version is自带的, now using the community edition may be due to minimalization considerations not default installing sudo pacman -S android-tools
# Turn on USB debugging on the phone and connect to the computer, if device is not registered in phone select allow current device debugging adb devices
# Get phone basic information to push corresponding version of minicap to the phone ABI=$(adb shell getprop ro.product.cpu.abi | tr -d '\r') SDK=$(adb shell getprop ro.build.version.sdk | tr -d '\r') adb push libs/$ABI/minicap /data/local/tmp/ adb push jni/minicap-shared/aosp/libs/android-$SDK/$ABI/minicap.so /data/local/tmp/ adb shell chmod 777 /data/local/tmp/minicap # Test if it can run adb shell LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x1920@1080x1920/0 –t # If running successfully, the last will display 'OK'
Screenshot

# The environment variable setting is necessary because it needs to specify the library path, -P后面的参数是截图参数, 详情可参见minicap的项目网页, -s but表截图并输出到 # 标准输出, 所以重定向就好 adb shell LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x1920@1080x1920/0 –s > /sdcard/minicap/test.jpg
To be completed
Wrap the above commands into a script, and set up wifi connection information at the same time, so you can control multiple devices simultaneously.
