Android手机视频监控JNI问题

C++与Java直接的数据格式貌似要转换一下吧！
高手过来看一下。

把你的错误发出来看看，看是不是参数传递有问题。检查检查吧！你的Java代码应该没问题

没有错误的问题是这样的比如我在Java层传一个用户名 admin到JNI层C里面取出来就不是admin了

你用的是Socket，搞了半天，这个我就不知道了，我还以为是Binder。
汗！建议你把结果告诉大家，你就说不是admin，那是什么？
Socket通信这块兄弟不熟，找这方面的高手吧！

应该要实现以下接口的：
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class VView */#ifndef _Included_VView
#define _Included_VView
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class:     VView
* Method:    InitDecoder
* Signature: ()I
*/
JNIEXPORT jint JNICALL Java_VView_InitDecoder
  (JNIEnv *, jobject);/*
* Class:     VView
* Method:    UninitDecoder
* Signature: ()I
*/
JNIEXPORT jint JNICALL Java_VView_UninitDecoder
  (JNIEnv *, jobject);/*
* Class:     VView
* Method:    DecoderNal
* Signature: ([BI[B)I
*/
JNIEXPORT jint JNICALL Java_VView_DecoderNal
  (JNIEnv *, jobject, jbyteArray, jint, jbyteArray);/*
* Class:     VView
* Method:    Connectiondvs
* Signature: (Ljava/lang/String;I)I
*/
JNIEXPORT jint JNICALL Java_VView_Connectiondvs
  (JNIEnv *, jobject, jstring, jint);/*
* Class:     VView
* Method:    Login
* Signature: (Ljava/lang/String;Ljava/lang/String;)I
*/
JNIEXPORT jint JNICALL Java_VView_Login
  (JNIEnv *, jobject, jstring, jstring);/*
* Class:     VView
* Method:    LiveVideo
* Signature: (I[B)I
*/
JNIEXPORT jint JNICALL Java_VView_LiveVideo
  (JNIEnv *, jobject, jint, jbyteArray);/*
* Class:     VView
* Method:    StopLive
* Signature: ()I
*/
JNIEXPORT jint JNICALL Java_VView_StopLive
  (JNIEnv *, jobject);#ifdef __cplusplus
}
#endif
#endif

其中Java_VView_Login就是这样的吧：
JNIEXPORT jint JNICALL Java_VView_Login(JNIEnv * env, jobject self, jstring user, jstring pswd)
{
const jbyte *pUser;
const jbyte *pPswd;
pUser = (*env)->GetStringUTFChars(env, user, NULL);
pPswd = (*env)->GetStringUTFChars(env, pswd, NULL);
if (NULL == pUser || NULL == pPswd)
{
return -1;
} // TODO: do login process. return 0;
}

AndroidManifest.xml注意添加Permission权限

朋友这是你的.h 我的也有这个，是.JAVA使用javac生成.class，然后再javah生成.h我们很一样啊，你也是在做h264的？我的是这样写的不错啊

朋友您说的我不是很懂什么权限？怎么加？
我吧我的AndroidManifest.xml粘贴上来
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.handlerun.view"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Sst"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".SplashActivity"
android:label="@string/splash_name">
</activity>

<activity android:name=".AlertQueryActivity"
android:label="@string/alertquery_name">
</activity>

<activity android:name=".AlertViewActivity"
android:label="@string/alertview_name">
</activity>

<activity android:name=".HelpActivity"
android:label="@string/help_name">
</activity>

<activity android:name=".LoginParmActivity"
android:label="@string/loginparm_name">
</activity>

<activity android:name=".MainMenuActivity"
android:label="@string/mainmenu_name">
</activity>

<activity android:name=".PictureListActivity"
android:label="@string/picturelist_name">
</activity> <activity android:name=".VideoListActivity"
android:label="@string/videolist_name">
</activity> <activity android:name=".VideoParmActivity"
android:label="@string/videoparm_name">
</activity>

<activity android:name=".RecordListActivity"
android:label="@string/recordlist_name">
</activity>

<activity android:name=".WaitActivity"
android:label="@string/wait_name">
</activity>

    <activity android:name=".H264Android"
               android:label="@string/H264_name">
    </activity>

    </application>
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE">
</uses-permission>
<uses-sdk android:minSdkVersion="8" />
</manifest>

c中实现的东西要确定在Android上是API Permission的，头文件可以利用javah生成，编码自己别抛异常问题不大。

朋友这个我不可以把那些变量定义成const因为我的这用户名和密码是根据不同用户改变的。另外不知道定义成char不使用byte可以不？

给为朋友我又重新整理了一下这个问题新帖子请看：
