 I/ActivityManager(283): Process PACKAGE NAME (pid 30880) has died.

And below is my ndk code of setting rate

JNIEXPORT void Java_PACKAGE NAME_receiver_AudioReceiver_NsetRate(
    JNIEnv* env, jclass clazz, jint rate) {
if (NULL != fdPlayerPlay) {

    SLresult result;
    LOGI("SET RATE");
    result = (*fdPlaybackRate)->SetRate(fdPlaybackRate, rate);

    assert(SL_RESULT_SUCCESS == result);

}
}

SO PLEASE ANYONE CAN TELL ME WHAT IS THIS ERROR AND HOW CAN I RESOLVE IT?

EDIT:

I have taken the native player code from here but its still giving the same error please help me out ,I can't figure it out what the error is :(

Use NDK addr2line to translate pc 000018aa to line number in your code.

It's not clear what fdPlayerPlay and fdPlaybackRate stand for, and how these are declared. But it's possible that the following line has a typo. Instead of

~~result = (*fdPlaybackRate)->SetRate(fdPlaybackRate, rate);~~

it should maybe read

result = (*fdPlayerPlay)->SetRate(fdPlaybackRate, rate);

if (NULL != fdPlayerPlay) {

it should maybe read

if (NULL != fdPlaybackRate) {

(as in OpenSLEngine.cpp:165)

I have tried this also but it gives error that fdPlayerPlay doesn't have method SetRate – Jan 27 '14 at 04:21
_Let me repeat:_ It's not clear what `fdPlayerPlay` and `fdPlaybackRate` stand for, and how these are declared. _And how they are initialized._ – Alex Cohn Jan 27 '14 at 09:37
you can have a look at the link I have in my question – Jan 27 '14 at 09:39
I don't see `fdPlayerPlay` on the page http://stackoverflow.com/questions/11094377/android-how-to-change-playback-rate-of-music-using-opensl-es. If you don't want to be cooperative, there is no reason to post your crash stack on this site. – Alex Cohn Jan 27 '14 at 09:46
ok fdPlayerPlay is a variable name of SLPlayItf which is a audio player in native and fdPlaybackRate is a variable name of SLPlaybackRateItf which is the the rate of the speed of the audio – Jan 27 '14 at 09:52
