C++调用android非静态函数
这是xcode下的代码
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
JniMethodInfo minfo;
bool isHave = JniHelper::getStaticMethodInfo(minfo,"org/com/TestFirst/ProcessManager","getInstance","()Ljava/lang/Object;");
CCLog("开始调用!");
jobject jobj=NULL;
if (isHave)
{
jobj = minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);
}
CCLog("取得jobj");
isHave = JniHelper::getMethodInfo(minfo,"org/com/TestFirst/ProcessManager","getProcess","()V");
CCLog("处理中!");
std::cout<<isHave<<std::endl;
if (isHave)
{
CCLog("接收!");
minfo.env->CallVoidMethod(jobj, minfo.methodID);
CCLog("完成!");
}
else
{
CCLog("jni-java函数执行完毕");
}
#endif

----------------------------
下面是eclipse下的java代码
package org.com.TestFirst;

import org.cocos2dx.lib.Cocos2dxActivity;
import android.app.Activity;
import android.app.ActivityManager;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.Button;
import android.widget.TextView;

public class ProcessManager extends Cocos2dxActivity{
private static String TAG = "AM_MEMORYIPROCESS" ;
private ActivityManager mActivityManager = null ;
public static ProcessManager actInstance=null;//定义单例
public static Object getInstance() {
if(actInstance==null)
{
actInstance=new ProcessManager();
}
Log.d("daa", "fsfsdf");
return actInstance;
}
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
public void getProcess()
{
Log.d("cocosAct","go on!!!");
}
}
执行以后,在LogCat里面能够看到xcode下打的log,但执行到minfo.env->CallVoidMethod(jobj, minfo.methodID),然后就崩了.
getProcess()里的log没有打印出来,这种调用非静态函数的方法在网上找的,大家都是这么写,不知道我错在哪里,求各位大侠帮忙解决解决. c++ android xcode eclipse

如果是在另外的线程中调用请检查是否有 (g_jvmInstance)->AttachCurrentThread(&env, NULL);

最开始的时候我并没有让ProcessManager类继承Activity类,这样调用非静态函数不会错,不过继承Activity类以后就出错了.

难怪啊，Activity是运行在UI线程的，你在其他地方怎么能调用它的成员方法呢？只能Activity本身能调用
