Cocos2d-x: Interaction Between cocos2d-x and Java layer through Jni

Today's research Cocos2d-x, whim want to do a 2dx call Android pop-up box effect. Use jni interaction with wood.

C ++ calls Java and Java calls C ++ (see below)

Void HelloWorld: menuCloseCallback (CCObject * pSender) {JniMethodInfo jmi; if (JniHelper: getStaticMethodInfo (jmi, "com/jni/test/JniTest", "sayHello ", "([Ljava/lang/String;) V") {jclass str_cls = jmi. env-> FindClass ("java/lang/String"); jstring str1 = jmi. env-> NewStringUTF ("I'm a titile"); jstring str2 = jmi. env-> NewStringUTF ("Are yor exit game? "); JobjectArray arrs = jmi. env-> NewObjectArray (2, str_cls, 0); jmi. env-> SetObjectArrayElement (arrs, 0, str1); jmi. env-> SetObjectArrayElement (arrs, 1, str2); jmi. env-> CallStaticVoidMethod (jmi. classID, jmi. methodID, arrs) ;}} extern "C" {/* naming rule: Java_Java package name_class name */void Java_com_jni_test_JniTest_sayHello () {CCLog ("hello java, i'm c ");}}

The effect is as follows: C ++ calls the Android dialog box
650) this. width = 650; "class =" alignnone size-full wp-image-883 max_width_img "alt =" Cocos2d-x cocos2d-x interaction with Java layer Jni "src =" http://www.bkjia.com/uploads/allimg/131228/0A232JK-0.png "style =" border: none; max-width: 100%; "/>
Java calls C ++ to print strings
