Jni Referans Tablosu taşması

Question

Android uygulamamda, bazı verileri döndüren yerel bir yöntemden kapsamlı bir şekilde yararlanıyorum.

Ancak bazı aramalardan sonra bir çökme elde ediyorum.

yerli denilen yöntemdir:

static jbyteArray JNIGetIcon(JNIEnv* e, jclass clazz) 
{ 
    ByteBuffer buff; 
    buff.Write(*icon, 48, 32, r66Api::IBitmap::TEncoding::EEnc_Rgba8888); 

    jbyteArray result = GetEnv()->NewByteArray(buff.Size()); 
    GetEnv()->SetByteArrayRegion(result, 0, buff.Size(), (jbyte*) buff.GetData()); 

    return result;  
} 

birisi yanlış yapıyorum bana gösterebilir misiniz?

Answer 1

Sana yanlış işlevi bakıyoruz düşünüyorum. Günlük mesajına göre, bir grup tutturulmuş karakter dizisi ("C") var. 1013 tanesi kesin olmalı.

Eşleşen bir Sürüm içermeyen GetStringChars veya GetStringCritical aramasını arayın.
