Android (ART) çarpışma UYGULAMASI HATA DETECTED: jarray geçersiz yığın dolaylı başvuru tablosu veya geçersiz referans

Question

Ben yerel C (NDK R10d) bir resim işleyen bir Android uygulaması yazıyorum olduğunu. Kod, JNI ile daha katı olan yeni ART girişine kadar iyi çalışıyordu. Bu yüzden kod Dalvik'le iyi çalışıyor (örneğin Lolipop öncesi cihazlarda) ancak ii en yeni telefonlarda bir SIGENV yaratıyor.

Java çalıştırmak kodudur:

/** 
    * Return the raw bytes of the native PIX object. You can reconstruct the 
    * Pix from this data using createFromPix(). 
    * 
    * @return a copy of this PIX object's raw data 
    */ 
    public byte[] getData() { 
     int size = nativeGetDataSize(mNativePix); 
     // Size is usually quite big since I work on pictures (1Mo-300Ko) 
     byte[] buffer = new byte[size]; 

     if (!nativeGetData(mNativePix, buffer)) { 
      throw new RuntimeException("native getData failed"); 
     } 

     return buffer; 
    } 

    private static native boolean nativeGetData(long nativePix, byte[] data); 

gelen doğal kodudur:

jboolean Java_com_googlecode_leptonica_android_Pix_nativeGetData(JNIEnv *env, 
     jclass clazz, jlong nativePix, jbyteArray data) { 
    PIX *pix = (PIX *) nativePix; 

    jbyte *data_buffer = env->GetByteArrayElements(data, NULL); 

    l_uint8 *byte_buffer = (l_uint8 *) data_buffer; 

    size_t size = 4 * pixGetWpl(pix) * pixGetHeight(pix); 
    memcpy(byte_buffer, pixGetData(pix), size); 

    env->ReleaseByteArrayElements(data, data_buffer, 0); 

    return JNI_TRUE; 
} 

GetByteArrayElements kaynağı olduğu görünüyor
şimdi hatası alıyorum hata, ama JNIEnv referans ve jbyteArray Android tarafından sağlanmıştır ve bunları saklamıyorum ya da değiştirmiyorum. Tampon dizisi her zaman aynı Java iş parçacığı içinde ayrılmış olduğundan, nasıl bozulduğunu göremiyorum ... Tamamen şaşırıyorum :)
Bu sorunun kaynağı ne olabilir?
Yığın çok mu küçük? Yoksa bir SANAT meselesi mi (gerçekten şüpheliyim ki ...)?
Yardımlarınız için teşekkürler!

Answer 1

bakın:

public byte[] getData() { 
     byte[] buffer = nativeGetData(mNativePix); 

     if (buffer == null) { 
      throw new RuntimeException("native getData failed"); 
     } 
     return buffer; 
    } 
    private static native byte[] nativeGetData(long nativePix); 

Yerli
JAVA

jbyteArray Java_com_googlecode_leptonica_android_Pix_nativeGetData(
     JNIEnv *env, jclass clazz, jlong nativePix) { 
    PIX *pix = (PIX *) nativePix; 
    // Get the size 
    size_t size = 4 * pixGetWpl(pix) * pixGetHeight(pix); 

    jbyteArray result = env->NewByteArray(size); 
    if (result == NULL) { 
     LOGE("Cannot allocate JNI Byte Array"); 

     return NULL; /* out of memory error thrown */ 
    } 
    // move from the Pix to the java structure 
    env->SetByteArrayRegion(result, 0, size,(jbyte*)pixGetData(pix)); 
    return result; 
} 

Teşekkürler!

Answer 2

Geçerli iş parçacığında geçerli yerel yöntem süresi için geçerli olduğu anlamına gelir. Özgün yöntem döndükten sonra nesnenin kendisi devam etse bile, başvuru geçerli değildir.

Bunu jclass/jarray bildiriminde değiştirmeyi deneyin.

jclass localClass = env->FindClass("MyClass"); 
jclass globalClass = reinterpret_cast<jclass>(env->NewGlobalRef(localClass));
