Question

我有一个简单的类扩展ResultReceiver，用于在服务和某些活动之间进行通信：

NSPredicate *predicate = [NSPredicate predicateWithFormat:
                               @"ANY region.beacons.minor = nil"];

它非常好用如果不使用带有minifyEnabled true的proguard 但如果我使用它，我会在发布后稍微崩溃：

android.os.BadParcelableException：Parcelable协议需要一个 Parcelable.Creator对象在类上称为CREATOR DataSyncResultReceiver

我尝试了以下proguard规则，没有成功：

import android.os.Bundle; 
import android.os.Handler; 
import android.support.v4.os.ResultReceiver;

@SuppressLint("ParcelCreator")
public class DataSyncResultReceiver extends ResultReceiver {

    private Receiver mReceiver;

    public DataSyncResultReceiver(Receiver receiver, Handler handler) {
        super(handler);
        setReceiver(receiver);
    }

    public interface Receiver {
        void onReceiveResult(int resultCode, Bundle resultData);
    }

    public void setReceiver(Receiver receiver) {
        mReceiver = receiver;
    }

    public boolean hasReceiver() {
        return mReceiver != null;
    }

    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {
        if (mReceiver == null) {
            Log.e("DataSyncResultReceiver", "Receiver is null");
        } else {
            mReceiver.onReceiveResult(resultCode, resultData);
        }
    }
}

有人可以帮我解决这个问题吗？

修复

-keep public class * extends android.support.v4.os.ResultReceiver

android.os.BadParcelableException（Proguard + extend ResultReceiver）
