Intent里嵌套放了intent且内层intent有自定义Parcelable对象时，会报错：
ClassNotFoundException when unmarshalling: xxx.xxx.IPCData
例子：A和B Activity甚至不用在不同进程都一样有问题
A Activity
Intent intent = new Intent(this, B.class);
Intent innerIntent = new Intent();
innerIntent.putExtra("key1", "value1");
IPCData ipcData = new IPCData();
ipcData.data = "data";
innerIntent.putExtra("data", ipcData);
intent.putExtra("intent", innerIntent);
startActivity(intent);
B Activity:
Intent intent = getIntent();
Intent innerIntent = intent.getParcelableExtra("intent");
IPCData data = innerIntent.getParcelableExtra("data");//没有这一行，只有下面一行时也一样的效果
String key1 = innerIntent.getStringExtra("key1");
IPCData:
import android.os.Parcel;
import android.os.Parcelable;
public class IPCData implements Parcelable {
public String data;
public IPCData(){}
protected IPCData(Parcel in) {
data = in.readString();
}
public static final Creator<IPCData> CREATOR = new Creator<IPCData>() {
@Override
public IPCData createFromParcel(Parcel in) {
return new IPCData(in);
}
@Override
public IPCData[] newArray(int size) {
return new IPCData[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(data);
}
}
解决方案：
B Activity:
Intent intent = getIntent();
Intent innerIntent = intent.getParcelableExtra("intent");
innerIntent.setExtrasClassLoader(IPCData.class.getClassLoader());
IPCData data = innerIntent.getParcelableExtra("data");
String key1 = innerIntent.getStringExtra("key1");
