我训练了一个对象检测模型，以使用Google AutoML检测四种植物，并将自定义的.tflite和.txt文件替换为从https://github.com/tensorflow/examples/tree/master/lite/examples/object_detection/android下载的模型。 在将应用程序安装到Android手机中之后，它一直崩溃，并显示消息该版本已过时。 这是我替换 DetectorActivity.java 中的.tflite和.txt文件的代码：
// Configuration values for the prepackaged SSD model.
private static final int TF_OD_API_INPUT_SIZE = 512;
private static final boolean TF_OD_API_IS_QUANTIZED = true;
private static final String TF_OD_API_MODEL_FILE = "plant_detect.tflite";
private static final String TF_OD_API_LABELS_FILE = "file:///android_asset/plant_list.txt";
private static final DetectorMode MODE = DetectorMode.TF_OD_API;
// Minimum detection confidence to track a detection.
private static final float MINIMUM_CONFIDENCE_TF_OD_API = 0.5f;
private static final boolean MAINTAIN_ASPECT = false;
private static final Size DESIRED_PREVIEW_SIZE = new Size(640, 480);
private static final boolean SAVE_PREVIEW_BITMAP = false;
private static final float TEXT_SIZE_DIP = 10;
OverlayView trackingOverlay;
private Integer sensorOrientation;
这是logcat中的错误：
