Thank you all, I figured out how to do it
on Java
(http://manski.net/2012/03/30/accessing-java-classes-from-mono-for-android-via-jni/)
create library
package com.mayastudios.jnitest;
import android.content.Context;
import android.net.ConnectivityManager;
import java.lang.reflect.Method;
public class JniTest {
public JniTest() {
// Force the user to create an instance
}
public String getGreetingText() {
return "Hello, 333 " + android.os.Build.MODEL;
}
public void setMobileDataEnabled(Context paramContext,boolean on)
{
try {
ConnectivityManager connectivityManager =
(ConnectivityManager)paramContext.getSystemService("connectivity");
Method method =
connectivityManager.getClass().getMethod("setMobileDataEnabled",
boolean.class);
method.invoke(connectivityManager, on);
} catch (NoSuchMethodException e)
{
e.printStackTrace();
} catch (Exception e)
{
e.printStackTrace();
}
}
public boolean getMobileDataEnabled(Context paramContext)
{
try {
ConnectivityManager connectivityManager =
(ConnectivityManager)paramContext.getSystemService("connectivity");
Method method =
connectivityManager.getClass().getMethod("getMobileDataEnabled");
return (Boolean) method.invoke(connectivityManager);
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
}
on VS
void EnableGPRS(Context ct)
{
bool on = false;
IntPtr nativeJavaClass =
JNIEnv.FindClass("com/mayastudios/jnitest/JniTest");
IntPtr defaultConstructor = JNIEnv.GetMethodID(nativeJavaClass,
"<init>", "()V");
IntPtr instance = JNIEnv.NewObject(nativeJavaClass,
defaultConstructor);
//IntPtr method1 = JNIEnv.GetMethodID(nativeJavaClass,
"getGreetingText", "()Ljava/lang/String;");
IntPtr method1 = JNIEnv.GetMethodID(nativeJavaClass,
"getMobileDataEnabled", "(Landroid/content/Context;)Z");
on = JNIEnv.CallBooleanMethod(instance, method1, new JValue(ct));
IntPtr method = JNIEnv.GetMethodID(nativeJavaClass,
"setMobileDataEnabled", "(Landroid/content/Context;Z)V");
JValue[] p = new JValue[] { new JValue(ct), new JValue(!on) };
IntPtr resultPtr = JNIEnv.CallObjectMethod(instance, method,p);
}
