在真机上测试APP的时候出现以下log

定位发现执行到下面红色注释位置，是因为我每次调用的时候都new 的原因吗！！！！关键是有时执行好久不会有问题，有时候一会就崩溃了，大神在哪里
public byte[] getMatrix() {
int width = this.getWidth();
int height = this.getHeight();
if(width == this.dataWidth && height == this.dataHeight) {
Log.d(TAG, "getMatrix: +++++++666666");
return this.yuvData;
} else {
int area = width * height;
Log.d(TAG, "getMatrix: +++++++");
Log.d(TAG, "getMatrix: area=" + area); //此处LOG会有
byte[] matrix = new byte[area]; //问题应出现在此处
Log.d(TAG, "getMatrix: +++++++"); //LOG不再打印
int inputOffset = this.top * this.dataWidth + this.left + 0;
if(width == this.dataWidth) {
System.arraycopy(this.yuvData, inputOffset, matrix, 0, area);
return matrix;
} else {
byte[] yuv = this.yuvData;

for(int y = 0; y < height; ++y) {
int outputOffset = y * width;
System.arraycopy(yuv, inputOffset, matrix, outputOffset, width);
inputOffset += this.dataWidth;
}

return matrix;
}
}
}
