ndk开发-5 异常处理

java代码

    public static native void nativeException();
    public static void doException() {
        int t = 0 / 0;
    }
//调用
  try {
         JniData.nativeException();
                } catch (Exception e) {
                    e.printStackTrace();
                }

native肛码

extern "C"
JNIEXPORT void JNICALL
Java_com_hrg_gys_clfr_myapplication_JniData_nativeException(JNIEnv *env, jclass clazz) {
    // 调用java的异常方法
    jmethodID jmethodId = env->GetStaticMethodID(clazz, "doException", "()V");
    env->CallStaticVoidMethod(clazz, jmethodId); //执行会产生异常 不处理异常应用会崩溃
    /*处理异常 应用不会崩溃*/
    jthrowable jthrowable1 = env->ExceptionOccurred();
    if (jthrowable1) {
        env->ExceptionDescribe();
        env->ExceptionClear();
        /*向java抛出异常*/
        jclass jclass1 = env->FindClass("java/lang/Exception");
        env->ThrowNew(jclass1, "native exception");
    }
