Question

我开始使用这个库，它显示了一个很好的上传进度条。 https://github.com/gotev/android-upload-service

按照文档我添加了一个BroadcastReceiver，但是，虽然上传作为服务运行并且更新得很好：

如果用户关闭了声明broadcastReceiver的活动，我将无法在上传结束时做出响应。如何保持对broadcastReceiver的引用？

注意：我尝试将接收器移动到单独的单例类，但这并没有解决问题。

broadcastReceiver：

public final UploadServiceBroadcastReceiver uploadReceiver =
        new UploadServiceBroadcastReceiver()    {

            // you can override this progress method if you want to get
            // the completion progress in percent (0 to 100)
            // or if you need to know exactly how many bytes have been transferred
            // override the method below this one
            @Override
            public void onProgress(String uploadId, int progress) {
                Log.i(TAG, "The progress of the upload with ID "
                        + uploadId + " is: " + progress);
            }

            @Override
            public void onProgress(final String uploadId,
                                   final long uploadedBytes,
                                   final long totalBytes) {
                Log.i(TAG, "Upload with ID " + uploadId +
                        " uploaded bytes: " + uploadedBytes
                        + ", total: " + totalBytes);
            }

            @Override
            public void onError(String uploadId, Exception exception) {
                Log.e(TAG, "Error in upload with ID: " + uploadId + ". "
                        + exception.getLocalizedMessage(), exception);


            }

            @Override
            public void onCompleted(String uploadId,
                                    int serverResponseCode,
                                    byte[] serverResponseBody) {
                // At this point, the serverResponseBody has been completely downloaded
                // and is cached in memory, so no NetworkOnMainThread could happen here
                Log.i(TAG, "Upload with ID " + uploadId
                        + " has been completed with HTTP " + serverResponseCode
                        + ". Response from server: "
                        + new String(serverResponseBody));

                String response = new String(serverResponseBody);

                dialog.dismiss();


                //If your server responds with a JSON, you can parse it
                //from serverResponseBody using a library
                //such as org.json (embedded in Android) or Google's gson
            }

            @Override
            public void onCancelled(String uploadId) {
                Log.i(TAG, "Upload with ID " + uploadId
                        + " has been cancelled by the user");


            }
        };

您可以创建一个新类（例如MyReceiver），它扩展UploadServiceBroadcastReceiver，在其中添加您的业务逻辑，然后将其注册为清单中的广播接收器（如下所示），并使用intent过滤器com.yourcompany.yourapp。 uploadservice.broadcast.status。通过这种方式，您可以独立于您的活动和服务来监听活动。使用初始设置中设置为UploadService.NAMESPACE的内容更改com.yourcompany.yourapp：

AndroidManifest.xml中的

<receiver android:name="MyReceiver">
    <intent-filter>
       <action    android:name="com.yourcompany.yourapp.uploadservice.broadcast.status" />
    </intent-filter>
</receiver>

MyReceiver.java

public class MyReceiver extends UploadServiceBroadcastReceiver {
   @Override
   public void onProgress(UploadInfo uploadInfo) {
    // your code here
   }

   @Override
   public void onCancelled(UploadInfo uploadInfo) {
    // Context context = getReceiverContext();
    // your code here
   }

   @Override
   public void onError(UploadInfo uploadInfo, Exception exception) {
      // Context context = getReceiverContext();
      // your code here
   }

   @Override
   public void onCompleted(UploadInfo uploadInfo, ServerResponse serverResponse) {
     // Context context = getReceiverContext();
     // your code here
   }
}

非常重要！如果您想使用UploadServiceBroadcastReceiver处理事件，请不要在任何地方调用setDelegate方法。

活动完成后，UploadServiceBroadcastReceiver关闭
