我試圖通過廣播在Intent中傳遞包含Analytics報告數據的對象。問題是反序列化返回LinkedTreeMap而不是原始的序列化對象,導致ClassCastException異常。 我試圖遵循所有在這裏找到的答案,從使用TypeToken來修改ProGuard規則,沒有任何工作。Gson的Google Analytics反序列化正在返回LinkedTreeMap
我想實現Parcelable接口,但問題是我有一個內部私人AsyncTask類,其中的數據被收集並推送到將通過廣播發送的意圖。
這裏就是數據序列化的輔助代碼:
public class AnalyticsHelper
{
...
private class GoogleBatchTask extends AsyncTask<GetReportsRequest,Void,GetReportsResponse>
{
@Override
protected GetReportsResponse doInBackground(@NonNull GetReportsRequest... reports)
{
GetReportsResponse response = null;
try {
if (m_reports == null)
return null;
response = m_reports.reports().batchGet(reports[0]).execute();
} catch (IOException e) {
Console.log(e);
}
return response;
}
@Override
protected void onPostExecute(GetReportsResponse response)
{
Intent intent = new Intent();
intent.setAction("com.keyone.contactpackapp.ANALYTICS_DATA");
intent.putExtra("response", new Gson().toJson(response));
Context context = PackConfig.instance().context();
if (context == null)
return;
context.sendBroadcast(intent);
}
}
}
AnalyticsFragment.java,其中反序列化發生了:
public class AnalyticsFragment extends Fragment
{
@Override
public void onResume()
{
super.onResume();
// Listen to custom intent with data
IntentFilter filter = new IntentFilter("com.keyone.contactpackapp.ANALYTICS_DATA");
m_receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent)
{
// Get data from intent and pass it to the right fragment
String szJson = intent.getStringExtra("response");
//m_response = new Gson().fromJson(szJson, GetReportsResponse.class);
Type listType = new TypeToken<GetReportsResponse>(){}.getType();
m_response = new Gson().fromJson(szJson, listType);
Fragment fragment = m_activity.currentFragment();
fragment.updateData();
}
};
if (m_activity != null)
m_activity.registerReceiver(m_receiver, filter);
}
}
