Question

我正试图从MainService开始MainActivity。但是，我从未看到日志打印输出确认服务的创建。

我应该使用onCreate，onStartCommand还是onHandleIntent？我已经尝试了所有三个，但没有任何工作。

MainActivity：

package hcii.tracker;

import android.content.Context;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;

import com.aware.Aware;
import com.aware.Aware_Preferences;


public class MainActivity extends ActionBarActivity {

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

        Log.d("ACTVITY", "ACT created!");

        Context context = this;
        //MainService main = new MainService();
        //main.startService();

        //Intent i= new Intent(context, MainService.class);
        //context.startService(i);

        Intent mServiceIntent = new Intent(this, MainService.class);
        this.startService(mServiceIntent);

       //Context context = this;
        //Aware.startPlugin(context, "com.aware.plugin.google.activity_recognition");

        //startService(new Intent(this, MainService.class));


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

MainService：

package hcii.tracker;

import android.app.IntentService;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;

import com.aware.Aware;
import com.aware.Aware_Preferences;

/**s

 */
public class MainService extends IntentService {

    public MainService(){
        super("MainService");
    }

   /*public void onCreate(){

        Log.d("SERVICE", "Service created!");

        Context context = this;
        //Activate Accelerometer
        Aware.setSetting(this, Aware_Preferences.STATUS_ACCELEROMETER, true);
        //Set sampling frequency
        Aware.setSetting(this, Aware_Preferences.FREQUENCY_ACCELEROMETER, 200000);
        //Apply settings
        sendBroadcast(new Intent(Aware.ACTION_AWARE_REFRESH));
        //Aware.startPlugin(getApplicationContext(), "com.aware.plugin.google.activity_recognition");
        Aware.startPlugin(context, "com.aware.plugin.google.activity_recognition");
    }*/

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Log.d("SERVICE", "Handle");

        Context context = this;
        //Activate Accelerometer
        Aware.setSetting(this, Aware_Preferences.STATUS_ACCELEROMETER, true);
        //Set sampling frequency
        Aware.setSetting(this, Aware_Preferences.FREQUENCY_ACCELEROMETER, 200000);
        //Apply settings
        sendBroadcast(new Intent(Aware.ACTION_AWARE_REFRESH));
        //Aware.startPlugin(getApplicationContext(), "com.aware.plugin.google.activity_recognition");
        Aware.startPlugin(context, "com.aware.plugin.google.activity_recognition");
    }

    /*@Override
    public int onStartCommand(Intent intent, int i, int u) {
        Log.d("SERVICE", "Start command");

        Context context = this;
        //Activate Accelerometer
        Aware.setSetting(this, Aware_Preferences.STATUS_ACCELEROMETER, true);
        //Set sampling frequency
        Aware.setSetting(this, Aware_Preferences.FREQUENCY_ACCELEROMETER, 200000);
        //Apply settings
        sendBroadcast(new Intent(Aware.ACTION_AWARE_REFRESH));
        //Aware.startPlugin(getApplicationContext(), "com.aware.plugin.google.activity_recognition");
        Aware.startPlugin(context, "com.aware.plugin.google.activity_recognition");
        return 0;
    }*/

背景服务指南可在https://developer.android.com/training/run-background-service/create-service.html找到。

您将在主要活动中使用startService方法，这将调用onHandleIntent。

看起来你的方式是正确的。但是，在您的清单<service...中应该是小写的。

Android服务无法从MainActivity启动
