NDK 19 error

[gryphon2411]

After cloning the repository, according to #358 comment I replaced:

APP_ABI := armeabi armeabi-v7a x86 mips

with:

APP_ABI := all

According to #181 comment I additionally tried to use NDK_TOOLCHAIN_VERSION := 4.9 in each of the following NDK's.

NDK 19 - didn't work

Errors:

• E/UVCCamera: [27355*UVCCamera.cpp:172:connect]:could not open camera:err=-1
• No video (blank)
• Not possible to use NDK_TOOLCHAIN_VERSION := 4.9:
  • /ndk-bundle/build/core/setup-toolchain.mk:52: *** Android NDK: Invalid NDK_TOOLCHAIN_VERSION value: 4.9. GCC is no longer supported. See https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md. . Stop.

NDK 18 - didn't work

Errors (same as NDK 19):

• E/UVCCamera: [27355*UVCCamera.cpp:172:connect]:could not open camera:err=-1
• No video (blank)
• Not possible to use NDK_TOOLCHAIN_VERSION := 4.9:
  • /ndk-bundle/build/core/setup-toolchain.mk:52: *** Android NDK: Invalid NDK_TOOLCHAIN_VERSION value: 4.9. GCC is no longer supported. See https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md. . Stop.

NDK 17 - work

Erros:

• E/libusb/usbfs: [31358*android_usbfs.c:1776:release_interface]:release interface failed, error -1 errno 22
• E/UVCCamera: [31358*UVCCamera.cpp:172:connect]:could not open camera:err=-99

When using NDK_TOOLCHAIN_VERSION := 4.9, the video worked, with the following warning:

Android NDK: WARNING: Deprecated NDK_TOOLCHAIN_VERSION 
value: 4.9. GCC is no longer supported and will be removed in the next release.

Shame on the Goog for not supporting GCC

For a related issue with a different app, I tried to migrate with [these instructions] (https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md), but encountered a build error

I downloaded the ndk v17c from here and everything worked fine I think
