Hi! All:
I've stuggle of this problem few days, search many hours but not sure
what's I should try.
Thanks in advance.
I have a native c function which take jintarray as a parameter, and I
wanna pass a int array to it.
I use GetIntArrayRegion to copy out the content of jintArray.
JNIEXPORT jstring Java_com_google_client_DecodeThread_test( JNIEnv*
env,
jobject this, jintArray
verts1 )
{
jint buf[307200];
(*env)->GetIntArrayRegion(env, verts1, 0, 307200, buf);
}
It seems work when I call this native function in an activity. (it
didn't crash ,at least)
But it always crash when I call this native function in an thread
which will be called in an activity.
I can't figure out why is that...
I saw many example, they just pass jintarray...
I also found that If I copy small part of the jintarray, it won't
crash.
Is there any memory limit of thread ?
or something related to GC and invalid array pointer?
The following is part of my code.
Thanks a lot for your help.
in java:
public native int testmem(int[] img);
private void decode_c()
{
...
System.loadLibrary("mydecoder");
int[] img_int = new int[307200];
int res= test(img_int ); ----------> it will crash here.I can't even
find out the error, the application closed.
...
}
in native c:
JNIEXPORT jstring Java_com_google_client_DecodeThread_test( JNIEnv*
env,
jobject this, jintArray
verts1 )
{
jint buf[307200];
(*env)->GetIntArrayRegion(env, verts1, 0, 307200, buf);
return (*env)->NewStringUTF(env, "show when no crash!");
}
