Подключить службу с приложением через AIDL в AOSP ⇐ Android

[Anonymous]

Я пытаюсь подключить службу HAL к приложению пользователя через AIDL. Я попробовал подключить приложение к обслуживанию без удачи. Как правильно подключить пользовательское приложение к службе HAL C ++ через AIDL? Что я делаю не так?package org.mwe.service;

interface IDummy {
String simple();

String complex(in byte[] from, out byte[] to, in String original, in int numeric);
}
< /code>
service < /h4>
Я добавил (по большей части, копировав интерфейс Vibrator AIDL) и реализацию по умолчанию. Полный код сервиса доступен здесь.
Service RC - < /p>
service mwe_dummy.service /vendor/bin/org.mwe.service.dummy-default myprefix
class hal
user root
group root
interface aidl org.mwe.service.IDummy/default
< /code>
Я могу подтвердить, что служба работает, выполняя команду < /p>
> adb shell service check org.mwe.service.IDummy/default
Service org.mwe.service.IDummy/default: found
< /code>
Я не могу напрямую выполнять методы через < /pbr /> > adb shell service call org.mwe.service.IDummy/default 1
Result: Parcel(NULL)
< /code>
app < ​​/h4>
Я обнаружил два подхода к соединению AIDL и реализовал оба: < /p>

с помощью intent < /li>
Прямое подключение < /li>
< /ol>
Полное код KOTLIN доступен здесь. Через намерение < /h5>
несколько упрощенный код подключения с помощью намерения заключается в следующем (почти точная копия примера) < /p>
class MainActivity : AppCompatActivity() {
private var service: IDummy? = null
private var isServiceBound = false
private val connection =
object : ServiceConnection {
override fun onServiceConnected(className: ComponentName, service: IBinder) {
service = IDummy.Stub.asInterface(service)
isServiceBound = true
}
override fun onServiceDisconnected(className: ComponentName) {
service = null
isServiceBound = false
}
}
private fun initConnectionIntent() {
if (isServiceBound) return
Intent(IDummy::class.java.name).apply { setPackage(getPackageName()) }.let {
bindService(it, connection, Context.BIND_AUTO_CREATE)
Log.d(TAG, "binding")
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
initConnectionIntent()
}
}
< /code>
с намерениями, построенным различными способами < /p>
Intent(IDummy::class.java.name).apply { setPackage(getPackageName()) }
// or
Intent(IDummy::class.java.name).apply {
setPackage(getPackageName())
setAction("org.mwe.service")
// or
Intent().apply {
component = ComponentName("org.mwe.service.IDummy", "default")
}
< /code>
Журнал показывает сообщение < /p>
ActivityManager: Unable to start service Intent { ... } U=0: not found
< /code>
прямое соединение < /h5>
несколько упрощенный код прямого подключения является следующим образом < /p>
class MainActivity : AppCompatActivity() {
private var service: IDummy? = null
private fun initConnectionDirect() {
val checkService =
Class.forName("android.os.ServiceManager")
.getMethod("checkService", String::class.java)
val bdr = checkService.invoke(null, "org.mwe.service.IDummy/default")!! as IBinder
service = IDummy.Stub.asInterface(bdr)
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
initConnectionDirect()
}
}

Пример кода использует ServiceManager , который помечен в Android, поэтому этот трюк используется для доступа к нему.I org.mwe.app: type=1400 audit(0.0:579): avc: denied { call } for scontext=u:r:untrusted_app:s0:c117,c256,c512,c768 tcontext=u:r:mwe_dummy_default:s0 tclass=binder permissive=1 app=org.mwe.app
