What for do we need ARM EABI v7a System image in Android development? What is the purpose of that particular image?
回答1:
if you work with the NativeDK, without that image the emulator is not able to simulate the execution of ARMv7 code (like multicore-instructions and NEON floating-point-unit)
回答2:
It is the kernel image. You must install it, otherwise the image won't start, failing with
ERROR: This AVD's configuration is missing a kernel file
回答3:
The system image is used by the emulator to virtualize the Android OS so Apps can be tested/debugged on a PC without the need to upload the App to a phone whenever a change in the code is made. This speeds up the development process and allows testing for phones that aren't physically available.
回答4:
That's the emulator image supporting ARMv7-A profile hardware, which is true for all new Android phones.
Since ARMv7-a is backward compatible with ARMv5, it is the only supported image with later system images.
回答5:
The only line I know,
I believe you need to use the Android SDK Manager, ARM EABI v7a System image to add that ARM EABI processor support to your local SDK.
回答6:
This package is responsible for faster floating point operations
