基于上一篇文章:
Android HIDL第一个demo编写: HIDL Test——实现Framework&App层与HAL进程IPC
使用的是Passthrough模式,这里修改为使用Binderized模式:
service.cpp文件写法:
#define LOG_TAG "vendor.mobis.hidltest@1.0-service"
#include <android-base/logging.h>
#include <hidl/HidlTransportSupport.h>
#include <hidl/LegacySupport.h>
#include "HidlTest.h"
// libhwbinder
using android::hardware::configureRpcThreadpool;
using android::hardware::joinRpcThreadpool;
using vendor::mobis::hidltest::V1_0::IHidlTest;
using vendor::mobis::hidltest::V1_0::implementation::HidlTest;
using android::sp;
using android::OK;
using android::status_t;
int main() {
//和dev/hwbinder进行通信,设置最大的线程个数为4
configureRpcThreadpool(1, true);
// register HidlTest service
sp<IHidlTest> mHidlTestService = new HidlTest();
status_t status = mHidlTestService->registerAsService();
if (status != OK) {
ALOGE("Cannot register HidlTest HAL service");
return 1;
}
ALOGI("TRIMBLE HidlTest HAL Ready.");
//把当前线程加入到线程池
joinRpcThreadpool();
return 1;
}
该service对应的bp文件中要增加HidlTest.cpp:
cc_binary {
proprietary: true,
relative_install_path: "hw",
defaults: ["hidl_defaults"],
name: "vendor.mobis.hidltest@1.0-service",
init_rc: ["vendor.mobis.hidltest@1.0-service.rc"],
srcs: ["service.cpp", "HidlTest.cpp"],
cflags: [
"-Wall",
"-Werror",
],
shared_libs: [
"liblog",
"libdl",
"libutils",
"libhardware",
"libhidlbase",
"libhidltransport",
"vendor.mobis.hidltest@1.0",
],
}
打印log查看结果:
junmatek@junmatek-HP-EliteDesk-800-G3-TWR:~$ adb logcat | grep -Ei "hello|HidlTest"
