Android检测车辆是否移动

Question

我正在开发类似优步的应用程序,如果车辆停止移动(或移动,我们需要计算等待时间)

我尝试使用GPS定位速度,但它似乎没有帮助.然后我们尝试了Activity识别API,它也没有立即更新.

有没有其他方法可以实现这一目标？请注意它不是关于检测速度.它涉及检测车辆是否在移动.

谢谢,Aneef

据我所知,你有3个选择:

1. 你可以实现自己的检测驾驶技术 - 使用活动识别和接收位置更新,虽然我建议不要这样做,不要重新发明轮子,已经开发了良好的apis.
2. 您可以使用Neura的免费sdk,当您的用户开始驾驶并完成驾驶时,它可以向您发送活动.看看这个git项目:基本上,当你开始驾驶时,项目会发布带有文字转语音的通知,这不是你想要的,但是当Neura向你发送开始/结束驾驶事件时,你可以做任何你想做的事情.很容易就可以把这个项目变成你自己的项目. 我强烈建议使用此选项.

3. 您可以使用谷歌的FenceApi来声明驾驶围栏.

   虽然这种方法似乎很好,但我面对这样一个事实,即当用户开始/完成驾驶时,这个api并没有告诉我,有时我开始驾驶后需要很长时间,api告诉我那个事件.

   一个.包括对应用程序的build.gradle文件的依赖:

      compile 'com.google.android.gms:play-services-location:+'
   
      compile 'com.google.android.gms:play-services-contextmanager:+'
   

   湾 清单定义:

   <uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />
   <uses-permission android:name="android.permission.INTERNET" />
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
   
   <application
       android:allowBackup="true"
       android:icon="@mipmap/ic_launcher"
       android:label="@string/app_name"
       android:supportsRtl="true"
       android:theme="@style/AppTheme" >
   
       <meta-data
           android:name="com.google.android.awareness.API_KEY"
           android:value="PUT_YOUR_AWARENESS_KEY_HERE" />
   
       <activity android:name=".MainActivity" >
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
   
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
   </application>
   

   PUT_YOUR_AWARENESS_KEY_HERE:您需要在此处生成密钥.

   C.您的MainActivity类 - 代码附带的解释:

   public class MainActivity extends Activity {
   
       private GoogleApiClient mGoogleApiClient;
       private PendingIntent mPendingIntent;
       private FenceReceiver mFenceReceiver;
   
       // The intent action which will be fired when your fence is triggered.
       private final String FENCE_RECEIVER_ACTION = BuildConfig.APPLICATION_ID + "FENCE_RECEIVER_ACTION";
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(Awareness.API).build();
           mGoogleApiClient.connect();
           // Set up the PendingIntent that will be fired when the fence is triggered.
           mPendingIntent = PendingIntent.getBroadcast(this, 0, new Intent(FENCE_RECEIVER_ACTION), 0);
           // The broadcast receiver that will receive intents when a fence is triggered.
           mFenceReceiver = new FenceReceiver();
           registerReceiver(mFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));
           createFence(DetectedActivityFence.IN_VEHICLE, "InVehicleFence");
       }
   
       @Override
       public void onDestroy() {
           try {
               unregisterReceiver(mFenceReceiver); //Don't forget to unregister the receiver
           } catch (Exception e) {
               e.printStackTrace();
           }
           super.onDestroy();
       }
   
       private void createFence(int detectedActivityFence, final String fenceKey) {
           AwarenessFence fence = DetectedActivityFence.during(detectedActivityFence);
           // Register the fence to receive callbacks.
           Awareness.FenceApi.updateFences(
                   mGoogleApiClient, new FenceUpdateRequest.Builder().addFence(fenceKey, fence, mPendingIntent)
                           .build()).setResultCallback(new ResultCallback<Status>() {
               @Override
               public void onResult(@NonNull Status status) {
                   if (status.isSuccess()) {
                       Log.i(getClass().getSimpleName(), "Successfully registered.");
                   } else {
                       Log.e(getClass().getSimpleName(), "Could not be registered: " + status);
                   }
               }
           });
       }
   
       // Handle the callback on the Intent.
       public class FenceReceiver extends BroadcastReceiver {
           @Override
           public void onReceive(Context context, Intent intent) {
               FenceState fenceState = FenceState.extract(intent);
               switch (fenceState.getCurrentState()) {
                   case FenceState.TRUE:
                       Log.i(fenceState.getFenceKey(), "Driving");
                       break;
                   case FenceState.FALSE:
                       Log.i(fenceState.getFenceKey(), "Not driving");
                       break;
               }
           }
       }
   }
