Question

我创建的funf应用程序只使用基本探测，如wifi和简单的位置。目前数据保存到SD卡，我希望它们保存到我的远程服务器。谢谢提前

public class MainActivity extends Activity实现DataListener {

public static final String PIPELINE_NAME = "default";
private FunfManager funfManager;
private BasicPipeline pipeline;
private WifiProbe wifiProbe;
private SimpleLocationProbe locationProbe;

        funfManager = ((FunfManager.LocalBinder)service).getManager();

        Gson gson = funfManager.getGson();
        wifiProbe = gson.fromJson(new JsonObject(), WifiProbe.class);
        locationProbe = gson.fromJson(new JsonObject(), SimpleLocationProbe.class);
        pipeline = (BasicPipeline) funfManager.getRegisteredPipeline(PIPELINE_NAME);
        wifiProbe.registerPassiveListener(MainActivity.this);
        locationProbe.registerPassiveListener(MainActivity.this);

        // This checkbox enables or disables the pipeline
        enabledCheckbox.setChecked(pipeline.isEnabled());
        enabledCheckbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (funfManager != null) {

您需要服务器上的数据库和一些后端功能才能将数据添加到远程数据库。后端函数应该在服务器上，你可以通过HttpRequest等从你的Android应用程序调用它。阅读REST API

Answer 2

要将数据发送到远程服务器，首先需要配置strings.xml

文件如下。

"archive": {
                "@schedule": {"interval": 60}
           },
"upload":  {
                   "url": \"http://example.com/test/android_data_receiver.php\",
                   "@schedule": {"interval": 60}
           }

它会每1分钟向服务器发送一次数据，并确保已添加

访问远程服务器到Android清单文件的权限

允许许可的代码

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.INTERNET" />

完成上述步骤后，请在您的域中创建一个服务器文件，对于

测试目的我在下面创建了一个文件。哟可以根据需要修改文件。

<?php

   $target_path  = "uploads/";
   $target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

   if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
        echo "The file ".  basename( $_FILES['uploadedfile']['name'])." has been uploaded";
   } 
   else {
        echo "There was an error uploading the file, please try again!";
   }
?>
