java - 如何在 Activity 中显示通过服务获取的数据？

Question

我有一个从网络下载一些数据的服务，但是当我尝试将其传递给 Activity 以将其显示给用户时，我收到以下错误:

E/JavaBinder:!!! BINDER 交易失败!!!

// 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

尝试

1.在您的 Activity 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)
