Java 来自JNI的警报对话框生成器调用中出现空指针异常
我知道有很多关于它的问题被问到了，我已经看到了这篇关于这类错误的文章，但是我正在参加一个关于JNI调用的特别比赛。 下面是我的工作： 我有一个单独的C++线程运行一些代码，在某个时候（在定时器结束后），我需要调用java中的回调函数。此回调函数用于显示一些警报，然后运行一些代码 基本上这里是我的代码C++侧：Java 来自JNI的警报对话框生成器调用中出现空指针异常,java,android,c++,java-native-interface,Java,Android,C++,Java Native Interface,我知道有很多关于它的问题被问到了，我已经看到了这篇关于这类错误的文章，但是我正在参加一个关于JNI调用的特别比赛。 下面是我的工作： 我有一个单独的C++线程运行一些代码，在某个时候（在定时器结束后），我需要调用java中的回调函数。此回调函数用于显示一些警报，然后运行一些代码 基本上这里是我的代码C++侧： JNIEXPORT void JNICALL package_endTrialJava(){ LOGD("EndTrialJava"); JNIEnv* env;
