当我运行Android应用程序时,我遇到了一个错误,我使用了JNI函数和c代码.当它运行时,我得到以下消息：@H_404_2@

@H_404_2@

Fatal signal 11 (SIGSEGV) at 0xe480001d (code=1),thread 5465@H_404_2@

最后这是我的代码：@H_404_2@

@H_404_2@

JNIEXPORT jstring JNICALL Java_ir_bassir_ndktest4_MainActivity_getName
(JNIEnv *env,jobject obj){

  jclass cls = (*env)->GetObjectClass(env,obj);
  jmethodID mid = (*env)->GetStaticMethodID(env,cls,"testJava","([Ljava/lang/String)[Ljava/lang/String");

  jstring plainText = (*env)->NewStringUTF(env,"Hello from JNI ! Compiled with ABI  2222 ");
  jstring result = (*env)->CallStaticObjectMethod(env,mid,plainText);

  return (*env)->NewStringUTF(env,plainText);
}

而在Java方面：@H_404_2@
