8 years ago Surround the code that appears to be generating an exception in a try-catch-finally block, and then report the error back here...

I am attempting to use JTransforms to compute a DoubleFFT_1D.
The full error message is this:
09-07 17:30:11.369 E/JavaBinder: *\ Uncaught remote exception! (Exceptions are not yet supported across processes.)
java.lang.NoClassDefFoundError: Failed resolution of: Lorg/jtransforms/fft/DoubleFFT_1D;

I have imported jtransforms as follows in the source file:
import org.jtransforms.fft.DoubleFFT_1D;
with the proper gradle entry:
apply plugin: 'java' dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile files('libs/JTransforms-3.1-with-dependencies.jar') }
And corresponding Android Studio dependency setting:
The project compiles without an error and throws and error at the following line:
// An array of length 4 will yield n = 8.
// This is necessary for the computation to be correct.
int n = 2 * nextPow2(x.length);
// Twice the number of elements are required: real and imaginary parts of the FFT are stored consecutively
double[] f = new double[2 * n];
System.arraycopy(x, 0, f, 0, x.length);
// FFT
DoubleFFT_1D fft = new DoubleFFT_1D((long) n); // ERROR ON THIS LINE
// Use "full" to avoid more machinations with symmetry
fft.realForwardFull(f);The value of n when the error is thrown is 1024 and the length of x is 500.
I have found this error with both: "JTransforms-2.4.jar" and "JTransforms-3.1-with-dependencies.jar".
Can you recommend any solutions?
Thank you.
