Sam*_*age 5 java serialization android
在我的Android应用程序中,我使用文件来存储许可证数据.我使用Serialize对象.我创建一个Device对象并将文件详细信息读入该对象.Device类实现Serializable.
public class MyDevice implements Serializable {}

但是在应用程序开始时,它反序列化并存储在MyDevice对象中.我的deserializeObject方法如下.
public MyDevice deserializeObject() {
File SerialFile = new File(GeoTrackerPaths.FILE_PATH);
MyDevice AndDeviceIn = new MyDevice();
if (SerialFile.exists()) {
try {
FileInputStream fileIn = new FileInputStream(GeoTrackerPaths.FILE_PATH);
ObjectInputStream objInput = new ObjectInputStream(fileIn);
AndDeviceIn = (MyDevice) objInput.readObject();
objInput.close();
fileIn.close();
} catch (Exception e) {
Log.i("TAG", "Exception during deserialization:" + e.getMessage());
e.printStackTrace();
System.exit(0);
}
}
return AndDeviceIn;
}

我的序列化代码
public void serializeObject(Context context, String phoneModel,
String androidVersion, String executiveCode, String Key,
String modelID, String tempKey, int noLogin, String expireDate, String Status) {
try {
MyDevice AndDeviceOut = new MyDevice(context, phoneModel,
androidVersion, new Date(), executiveCode, Key, modelID,
tempKey, noLogin, expireDate, Status);
FileOutputStream fileOut = new FileOutputStream(
GeoTrackerPaths.FILE_PATH);
ObjectOutputStream objOutput = new ObjectOutputStream(fileOut);
objOutput.writeObject(AndDeviceOut);
objOutput.flush();
objOutput.close();
fileOut.close();
} catch (Exception e) {
Log.i("TAG", "Exception during serialization:" + e.getMessage());
e.printStackTrace();
System.exit(0);
}
}

而我将其称为如下.
DeviceActivator activate=new DeviceActivator();
activate.serializeObject(Activation.this, phoneModel, androidVersion, txtExe, exeKey, modeilID, tempKey, noLogin, expireDate, Activation_Status);

当我运行应用程序时,会引发异常.
java.io.WriteAbortedException: Read an exception;
java.io.NotSerializableException: com.geotracker.entity.MyDevice
