Android jni GetMethID崩潰

我嘗試用jni在c中構建java對象。並且使用一些代碼象下面這樣：Android jni GetMethID崩潰

jmethodID method_cls_video_info_set_duration = (*env)->GetMethodID(env, cls_video_info, "setDuration", "(J)V"); 
LOGD("4"); 
jmethodID method_cls_video_info_set_audio_codec = (*env)->GetMethodID(env, cls_video_info, "setAudioCodec", "(Ljava/long/String;)V"); 
LOGD("11"); 
jmethodID method_cls_video_info_set_video_codec = (*env)->GetMethodID(env, cls_video_info, "setVideoCodec", "(Ljava/long/String;)V"); 
LOGD("9");

但是，我得到了一個崩潰的位置：

jmethodID method_cls_video_info_set_video_codec = (*env)->GetMethodID(env, cls_video_info, "setVideoCodec", "(Ljava/long/String;)V");

和日誌是這樣的：

你能共享Java類？ –

這是我的錯，我使用String類的包名錯誤。它應該是

java/lang/String;

而不是

java/long/String;

。:)
