Steps:
create dynamic proxy instance
call native method and pass the proxy instance as a parameter
use jni to invoke some method on proxy instance
App code:
val target = object : ProxyTest {
override fun testVoid() {
Log.e(TAG, "testVoid: ")
}
override fun testString(): String {
Log.e(TAG, "testString: ")
return "hello"
}
}
val proxy = Proxy.newProxyInstance(
classLoader, arrayOf(ProxyTest::class.java)
) { proxy, method, args ->
// if open code below, it will crash on all device
// if not open, it will crash only on android 6.0, mostly on Vivo Y67
//val myargs = args ?: emptyArray()
//method.invoke(target, *myargs)
} as ProxyTest
invokeProxyMethod(proxy)
interface ProxyTest {
fun testVoid()
fun testString(): String
}
Native code:
extern "C"
JNIEXPORT void JNICALL
Java_com_aprz_mytestdemo_jni_JNIInvokeProxyMethodActivity_invokeProxyMethod(JNIEnv *env,
__unused jobject thiz,
jobject proxy) {
jclass proxy_class = env->GetObjectClass(proxy);
// jmethodID test_void_method_id = env->GetMethodID(proxy_class, "testString", "()Ljava/lang/String;");
jmethodID test_void_method_id = env->GetMethodID(proxy_class, "testVoid", "()V");
LOGD("jmethodId = %d", test_void_method_id == nullptr);
jvalue *args = {};
jobject obj = env->NewLocalRef(proxy);
env->CallVoidMethodA(obj, test_void_method_id, args);

"Not reproducible with: 2017.4.23f1, 2018.3.0b3"
This is not entirely true. With 2018.3.0b3 we have in 5 times less crashes, but still have.
