android - 使用钛模块启动 android native 服务

Question

我使用以下服务类启动了一个移动模块项目:

package com.eliddell.testservice;

import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;
import java.util.Timer;
import java.util.TimerTask;

import android.content.BroadcastReceiver;

import android.content.Context;
import android.content.Intent;

import android.graphics.PixelFormat;


import android.net.wifi.WifiManager;
import android.os.BatteryManager;
import android.os.Handler;
import android.os.IBinder;
import android.text.format.Time;

import android.view.Gravity;

import android.view.WindowManager;

import android.widget.RelativeLayout;

import android.widget.TextView;



public class ForegroundService extends Service {

    /* (non-Javadoc)
     * @see android.app.Service#onBind(android.content.Intent)
     */
    Timer timer;

    WindowManager.LayoutParams handleParams;

    WindowManager.LayoutParams indiParams;

    View disableStatusBar;

    WindowManager winMgr;

    int interval = 50;

    Handler mHandler;

    Boolean secDialog = false;


    ArrayList<String> allowedApps;

    int scale = -1;

    int level = -1;

    int charging = 0;
    BroadcastReceiver batteryReceiver;

    @Override
    public void onCreate() {
        Log.v("Nav Service: ", "{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{CREATED");
        // Start up the thread running the service.  Note that we create a
        // separate thread because the service normally runs in the process's
        // main thread, which we don't want to block.  We also make it
        // background priority so CPU-intensive work will not disrupt our UI.
        allowedApps = new ArrayList<String>();
        /*allowedApps.add("com.sapientnitro.lcinstore2");//LC
        allowedApps.add("com.adobe.reader");//acrobat
        allowedApps.add("com.dynamixsoftware.printershare");//printer share
        allowedApps.add("my.handrite.prem");//HandRite Pro
       */
        mHandler = new Handler();
        //batMan = new BatteryManager();
        winMgr = (WindowManager) getSystemService(WINDOW_SERVICE);
        //cTime = new Time(Time.getCurrentTimezone());




    }


    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.v("Nav Service: ", "{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{started");
        disableStatusBar = new RelativeLayout(getApplicationContext());

        handleParams = new WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT, 50,
        // This allows the view to be displayed over the status bar
        // WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |  
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                // this is to keep button presses going to the background window
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                        | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
                        // this is to enable the notification to recieve touch events
                        WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
                        // Draws over status bar
                        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,

                PixelFormat.TRANSPARENT);
        handleParams.gravity = Gravity.TOP;
        handleParams.y = 50;



        disableStatusBar.setBackgroundColor(0xffff0000);

        winMgr.addView(disableStatusBar, handleParams);




        statusChecker.run();

        // If we get killed, after returning from here, restart
        return START_REDELIVER_INTENT;
    }

    @Override
    public IBinder onBind(Intent intent) {

        // We don't provide binding, so return null
        return null;
    }

    @Override
    public void onDestroy() {

        unregisterReceiver(batteryReceiver);
        mHandler.removeCallbacks(statusChecker);
        winMgr.removeView(disableStatusBar);
        //Toast.makeText(this, "service done", Toast.LENGTH_SHORT).show(); 
    }


    Runnable statusChecker = new Runnable() {

        public void run() {

            mHandler.postDelayed(statusChecker, interval);
        }

    };




    private void monitorUser() {
        String cProcess;
        try {

            ActivityManager am = (ActivityManager) getApplicationContext().getSystemService(
                    Context.ACTIVITY_SERVICE);

            List<ActivityManager.RunningTaskInfo> processList = am.getRunningTasks(5);
            //screen capture tool
            am.killBackgroundProcesses("com.diotek.screen_capture");
            cProcess = processList.get(0).baseActivity.getPackageName();
            //Log.v("","--------------------------------------------------------------------------------"+cProcess);
            if (cProcess.equals("com.android.settings")) {
                launchSecurity();

            } else if(!allowedApps.contains(cProcess)){
               goHome();
            }


            Object service = getSystemService("statusbar");

            Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
            Method collapse = statusbarManager.getMethod("collapse");
            Method disable = statusbarManager.getMethod("disable", Integer.TYPE);
            collapse.setAccessible(true);
            // disable.invoke(service,1);
            //collapse .invoke(service);

        } catch (Exception ex) {
            Log.v("WINDOW CHANGE", "exemption:" + ex);
        }
    }

    public void launchSecurity() {


            Log.v("LAUNCHING", "((((((((((((((((((((SECURITY)))))))))))))))))");
            Intent i = new Intent("com.eliddell.testservice.activities.AUTHENTICATE");
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(i);

    }

    private boolean isSecurityServiceRunning() {

        ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {

            if ("com.eliddell.services_test.services.SecurityService".equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }
    public void goHome(){
        Intent startMain = new Intent(Intent.ACTION_MAIN);
        startMain.addCategory(Intent.CATEGORY_HOME);
        startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(startMain);
       /* Intent i = new Intent(Intent.ACTION_VIEW);
        i.setComponent(new ComponentName("com.sapientnitro.lcinstore2",
                "com.sapientnitro.lcinstore2.activities.MainActivity"));
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(i);*/
    }

}

我的模块很好地加载到我的 Titanium 应用程序中，模块中调用服务的 kroll 方法如下所示

@Kroll.method
    public void startForegroundService()
    {                  
        Log.v("{{{{{{{{{{{{{{{{{", "ATTEMPTING TO start service");


        try{

            backOverlayService = new Intent();
            backOverlayService.setClassName("com.eliddell.testservice", "ForegroundService.class");
            //start it
            //this.getActivity().getApplicationContext().startService(backOverlayService);
            TiApplication.getInstance().startService(backOverlayService);
            Log.v("TestserviceModule{{{{{{{", "TRY SUCCESS");
        }catch(Exception ex)
        {
            Log.v("TestserviceModule{{{{{{{", "Exception caught:"+ex);
        }




    }

日志显示成功，但实际服务在 onCreate 和 onStart 中的日志实际上从未触发。

知道我做错了什么吗？

Answer 1

问题出在我设定 Intent 的方式上。

代替:

backOverlayService = new Intent();
backOverlayService.setClassName("com.eliddell.testservice", "ForegroundService.class");

我使用:

backOverlayService = new Intent(TiApplication.getAppCurrentActivity(), ForegroundService.class);
