JNI memory leaks local reference table overflow (max=512)

01-02 00:02:35.064:E/DALVIKVM (4223): JNI ERROR (App bug): Local reference table overflow (max=512)

This error can be caused by a large amount of data being passed to JNI, or when a large number of objects are new, if not released in time.

1. After converting Java string to native string, the Releasestringutfchars release is invoked.

if (mnull!= pszpath && mnull!= strjstring)
{
Env->releasestringutfchars (strjstring, Pszpath);
}

2. Call (env)->deletelocalref (obj) after using the Java pass-through obj;
