java如何在活动中显示通过服务获得的数据？

Question

我有一个从网上下载一些数据的服务，但当我试图将其传递给活动并向用户显示时，我收到以下错误：

E/JavaBinder:！！！活页夹事务失败

// This gets populated in the server based on information from a server.
byte[] downloadedData; 
// Instantiated downloadedData from server connection, code removed for brevity. 

// Try to start activity with downloaded data.
Intent i = new Intent(this, MainActivity.class);
i.putExtra("DATA", downloadedData);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);

Answer 1

试试看

1在活动中注册自定义广播接收器

context.registerReceiver (myBroadcastReceiver, new IntentFilter ("CUSTOM_ACTION"));
private final BroadcastReceiver myBroadcastReceiver = new BroadcastReceiver () {

    @Override
    public void onReceive (Context context, Intent intent) {

        //Do something
    }
};

2从您的服务发送广播

Intent intent = new Intent ("CUSTOM_ACTION");
intent.putExtra("DATA", downloadedData);
context.sendBroadcast (intent)
