我有下一个问题，我正在创建一个自定义适配器的列表视图，我正在使用异步任务从JSON url（文本和图像URL）下载适配器的数据，然后我设置了适配器在列表中，我使用毕加索库下载图像，现在我的应用程序工作正常，它不会崩溃但是当我开始另一个活动时，我得到了这个：
E / JavaBinder：!!!失败的粘合剂交易!!!即使新活动为空，我也会收到错误，我正在使用moto G.我已经使用DDMS和Eclipse MAT分析了堆，我还没有发现我的代码是否导致内存泄漏。多次从一个活动变为另一个活动我在logcat中得到了这个：

正如您所看到的，内存堆没有增加，但我以同样的方式得到错误。
我不认为问题在于我为第一个活动下载的位图，因为我评论了涉及位图的所有代码行，我还评论了asynctasks并且问题继续出现，无论如何我要把适配器放在这里：
class ClientListAdapter extends BaseAdapter {
private Context context;
private ClientList clients;
private ClientList arrayList;
public ClientListAdapter(Context context, ClientList clients) {
this.context = context;
this.clients = clients;
this.arrayList = new ClientList();
this.arrayList.addAll(clients);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Client client = clients.get(position);
ClientHolder clientHolder = new ClientHolder();
if(convertView == null){
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(R.layout.client_list_item,parent,false);
clientHolder.clientName = (TextView) convertView.findViewById(R.id.client_name);
clientHolder.clientImage = (ImageView) convertView.findViewById(R.id.client_image);
convertView.setTag(clientHolder);
}
else{
clientHolder = (ClientHolder) convertView.getTag();
}
if (client != null) {
clientHolder.clientImage.setImageResource(R.drawable.ic_launcher);
Picasso.with(context).load(client.getClientImageUrl()).into(clientHolder.clientImage);
clientHolder.clientName.setText(client.getName());
}
return convertView;
}
static class ClientHolder{
TextView clientName;
ImageView clientImage;
}
我下载了Eclipse MAT，它显示了泄漏可能的原因，但我不太清楚这意味着什么，这是Eclipse MAT的结果：

当应用程序调用intent并进入其他活动时会出现错误，所以我认为我没有正确地清理第一个活动的内存并且堆积在其中两个导致错误。但正如您在logcat中看到的那样，当我从一个活动更改为另一个活动时，内存堆是稳定的并且不会增加。有时我也会得到这个：
I/dalvikvm﹕ threadid=3: reacting to signal 3
更新： 我观察到的另一件事是我在三星ACE，Moto Razr Z3和Galaxy Tab 2中运行代码，即使这些设备的内存比Moto g少，也不会出现错误，这可能是错误或摩托车上的错误？

捆绑包可以包含多少数据存在一些限制。如果您的捆绑或意图附加功能太大，您可能会收到此错误。您是否将数据传递到捆绑包中？
