android_demo 启动异常 error: no member named 'IsOpenCLBackendValid' in namespace

[dfhao]

android_demo 项目用最新的 android studio，gradle 6.5 jdk8，ndk21.1
启动时，项目报错 PaddleOCR-release-2.7/deploy/android_demo/app/src/main/cpp/ppredictor.cpp:22:52: error: no member named 'IsOpenCLBackendValid' in namespace 'paddle::lite_api'
bool is_opencl_backend_valid = paddle::lite_api::IsOpenCLBackendValid(/check_fp16_valid = false/);

不懂 c++ 的逻辑
