英文:
Android Intent pass Object between different different apps
问题
我有这个 Activity（MainActivity，来自包名为 com.example.myapplication 的包），它接收一个名为“BeanValidacion”的类的 Intent。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Bundle willirex = getIntent().getExtras();
if(willirex!=null)
{
BeanValidacion datos = (BeanValidacion) willirex.get("paramIn");
Toast.makeText(MainActivity.this,datos.getIdNumber(),Toast.LENGTH_LONG).show();
}
}
而我想通过另一个 APK（包名为 com.adon.intents 的包）来调用它，并发送一个 Intent，就像我用字符串 Intent 做的那样，但这一次，我想发送一个名为“BeanValidacion”的类的对象。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BeanValidacion datos = new BeanValidacion();
datos.setIdNumber("12345");
Intent next = new Intent();
next.setClassName("com.example.myapplication", "com.example.myapplication.MainActivity");
next.putExtra("paramIn", datos);
startActivity(next);
}
当我执行 com.adon.intents APK 来发送这个 Intent 时，在 com.example.myapplication 中出现了这个错误：
> ClassNotFoundException 读取可序列化对象（名称 = com.adon.intents.BeanValidacion）
出现在这行代码：
Toast.makeText(MainActivity.this, datos.getIdNumber(), Toast.LENGTH_LONG).show();
在仅发送一个字符串时不会发生这种情况，但我在解决这个问题时遇到了问题。
谢谢。
英文:
I have this Activity (the MainActivity, from package package com.example.myapplication) that receives an Intent of class "BeanValidacion".
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Bundle willirex = getIntent().getExtras();
if(willirex!=null)
{
BeanValidacion datos = (BeanValidacion) willirex.get("paramIn");
Toast.makeText(MainActivity.this,datos.getIdNumber(),Toast.LENGTH_LONG).show();
}
And I want to call it with a different APK (package com.adon.intents) and send an Intent, as I do with String Intents, but this time, I want to send an object of class "BeanValidacion":
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BeanValidacion datos = new BeanValidacion();
datos.setIdNumber("12345");
Intent next = new Intent();
next.setClassName("com.example.myapplication", "com.example.myapplication.MainActivity");
next.putExtra("paramIn", datos);
startActivity(next);
}
When I execute the com.adon.intents APK to send the intent, I got this error on com.example.myapplication:
> ClassNotFoundException reading a Serializable object (name = com.adon.intents.BeanValidacion
In this line:
Toast.makeText(MainActivity.this,datos.getIdNumber(),Toast.LENGTH_LONG).show();
This doesn't happen when sending just a String, but I am having problems solving this one.

得分: 1
你应该将 BeanValidacion.java 文件放在第二个应用程序中与 com.adon.intents.BeanValidacion 完全相同的包层次结构中。此外，这两个类的 serialVersionUID 应该相同。
英文:
You should put the BeanValidacion.java file in the exact package hierarchy com.adon.intents.BeanValidacion on the second app. Also, both classes should have the same serialVersionUID.
