Question

我刚开始使用卵石，我下载了他们的海洋调查演示程序：https://github.com/pebble/pebble-sdk-examples/tree/master/data-logging-demo/OceanSurveyDemo-Android

但是当我在cloudpebble上运行它和演示时，我看到的只是我的Android应用程序上的黑屏。我想知道是否还有其他任何我想让数据记录在这里正常工作？我还尝试了其他一些示例，如下所示：http://developer.getpebble.com/guides/mobile-apps/android/android-datalogging/

我从cloudpebble上的日志记录会话中返回DATA_LOGGING_SUCCESS但是当我使用他们提供的接收代码时，我的手机上没有显示任何内容：

package com.getpebble.dataloggingtest;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.widget.TextView;

import com.getpebble.android.kit.PebbleKit;
import com.getpebble.android.kit.PebbleKit.PebbleDataLogReceiver;

import java.util.UUID;

/**
 * MainActivity class
 * Implements a PebbleDataLogReceiver to process received log data, 
 * as well as a finished session.
 */
public class MainActivity extends Activity {

  // Configuration
  private static final UUID WATCHAPP_UUID = UUID.fromString("12258306-6cff-4b67-8af3-6f14105e8d8f");
  private static final int DATA_LOG_TAG_COMPASS = 52;

  // App elements
  private PebbleDataLogReceiver dataloggingReceiver;
  private TextView textView;
  private StringBuilder resultBuilder = new StringBuilder();

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Setup TextView
    textView = (TextView)findViewById(R.id.text_view);
    textView.setText("Waiting for logging data...");
  }

  @Override
  protected void onResume() {
    super.onResume();

    // Define data reception behavior
    PebbleDataLogReceiver dataloggingReceiver = new PebbleDataLogReceiver(WATCHAPP_UUID) {

      @Override
      public void receiveData(Context context, UUID logUuid, Long timestamp, Long tag, int data) {
        // Check this is the compass headings log
        if(tag.intValue() == DATA_LOG_TAG_COMPASS) {
          // Get the compass value and append to result StringBuilder
          resultBuilder.append("Heading: " + data + " degrees");
          resultBuilder.append("\n");
        }
      }

      @Override
      public void onFinishSession(Context context, UUID logUuid, Long timestamp, Long tag) {
        super.onFinishSession(context, logUuid, timestamp, tag);

        // Display all compass headings received
        textView.setText("Session finished!\n" + "Results were: \n\n" + resultBuilder.toString());
      }

    };

    // Register DataLogging Receiver
    PebbleKit.registerDataLogReceiver(this, dataloggingReceiver);
  }

  @Override
  protected void onPause() {
    super.onPause();

    // Always unregister callbacks
    if(dataloggingReceiver != null) {
      unregisterReceiver(dataloggingReceiver);
    }
  }
}

我一定是在误解某些东西，但为什么我的手机没有得到任何数据？我在Android Studio中没有看到任何错误。

Answer 1

我认为您没有获得任何数据，因为您需要按下手表上的按钮才能开始向手表发送数据。

Pebble Data Logging for Android没有做任何事情
