你好 能否留下联系方式,led.cpp作为client 他是直通式吗?
绑定式HAL,java客户端调用Service和C++调用能传对象吗?
实现java调用hidl service的例子
2.1 添加库:
将以下内容添加到 Android.mk 中:
LOCAL_JAVA_LIBRARIES += android.hardware.foo-V1.0-java
或
将以下内容添加到 Android.bp 中:
shared_libs: [
/* … /
"android.hardware.foo-V1.0-java",
],
该库还存在静态版:android.hardware.foo-V1.0-java-static。
2.2 将以下内容添加到您的 Java 文件中:
import android.hardware.foo.V1_0.IFoo;
...
// retry to wait until the service starts up if it is in the manifest
IFoo server = IFoo.getService(true / retry /); // throws NoSuchElementException if not available
IFoo anotherServer = IFoo.getService("second_impl", true / retry */);
server.doSomething(…);
实现C++ 调用hidl service的例子
首先将 HAL 库添加到 makefile 中:
Make:LOCAL_SHARED_LIBRARIES += [email protected]
Soong:shared_libs: [ …, [email protected] ]
接下来,添加 HAL 头文件:
#include <android/hardware/nfc/1.0/IFoo.h>
…
// in code:
sp client = IFoo::getService();
client->doThing();
