安卓 JNI在应用程序中检测到错误：调用JNI CallIntMethodV时出现挂起的异常java。lang.NoSuchMethodError:没有非静态方法

Question

我正在用opencv在安卓 studio中做应用程序。代码如下

java.util.List<Mat> result = new java.util.ArrayList<Mat>(2);
List<java.lang.String> outBlobNames = new java.util.ArrayList<java.lang.String>();
outBlobNames.add(0, "yolo_16");
outBlobNames.add(1, "yolo_23");
tinyYolo.forward(result, outBlobNames);

我这行有个错误

tinyYolo.forward(result, outBlobNames);

错误

JNI DETECTED ERROR IN APPLICATION: JNI CallIntMethodV called with pending exception
java.lang.NoSuchMethodError: no non-static method "Ljava/util/ArrayList;.get((I)Ljava/lang/Object;"
