Game crash when starting new intent

cocos2d-x C++
#1

Hi everyone,

Is there anyway to start new intent in Android without cause game crashed?? I want my game open an URL, so I tried to start another Activity with WebView. But it doesn’t work :frowning:

This is what I tried

  • First, I add a function to start new Activity in my current Activity

public static void openURL(String url)
{
Intent intent = new Intent(m_sInstance.getApplicationContext(), WebViewActivity.class);
m_sInstance.startActivity(intent);
}

  • Second, I add some native code that I can open an URL in C++:
    jni_wrapper.h

#include <jni.h>
>
#include <android/log.h>
>
#define LOG_TAG “JNI”
#define LOGD (…) *android_log_print
#define LOGI (…)*android_log_print(ANDROID_LOG_INFO,LOG_TAG,VA_ARGS)
>
#define JNI_FUNCTION(function) Java_my_android_loadweb_ ## function
>
#ifndef JNI_WRAPPER
#defineJNI_WRAPPER
#ifdef cplusplus
extern “C” {
#endif
>
extern JNIEnv mEnv;
extern jclass mClassGame;
>
static jmethodID mMethodOpenURL;
>
void nativeOpenURL;
#ifdef cplusplus
}
#endif
jni_wrapper.c
#include <stdio.h>
>
#include “jni_wrapper.h”
>
#ifdefcplusplus
extern “C” {
#endif
>
JNIEnvmEnv;
jclass mClassGame;
>
JNIEXPORT void JNICALL JNI_FUNCTION
{
LOGI (“JNI nativeInit”);
>
mEnv = env;
mClassGame = ->NewGlobalRef;
>
mMethodOpenURL = ->GetStaticMethodID V");
}
>
void nativeOpenURL
{
// JNIEnv *mEnv = NVThreadGetCurrentJNIEnv;
jstring string = ->NewStringUTF;
->CallStaticVoidMethod;
// ->DeleteLocalRef;
}
>
#ifdefcplusplus
}
#endif

  • Finally, I call nativeOpenURL(…) in HelloWorldScene.cpp

void HelloWorld::menuCloseCallback(CCObject* pSender)
{
nativeOpenURL(“http://www.google.com”);
// CCDirector::sharedDirector()->end();
>
// #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
// exit(0);
// #endif
}

=> But it’s crashed, I tried to get stack trace, and here is the result

I attached all of them below. Here are some info:

Cocos version: cocos2d-2.0-rc2-x-2.0.1

Thanks a lot :slight_smile:

Hi,

It works, thanks a lot.

At first, when I used only Handler, game crash after I call open browser. So, I tried to use a Looper instead. And it works :smiley:
