前台的服务就会被杀死，每次

本文介绍了前台的服务就会被杀死，每次的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

当我开始我的服务，拉链很多，它总是被打死在后台文件后约8％，15-30秒。我怎样才能prevent这一点，让我的服务完成其任务？该服务未绑定到任何东西，可能这个问题？

//编辑：我创建了一个前台的服务出来，但它仍然被终止。

解决方案

我不使用的问题解决了服务，但 IntentService 。然后，我把整个的压缩和解code到 IntentService 并调用 startForeground 之前。拉拉链完成后我称之为 stopForeground ，一切完美的作品。

When I start my service that zips a lot of files in background it always gets killed after about 8% and 15-30 seconds. How can I prevent that and let my service finish its task? The service is not bound to anything, might this be the problem?

//EDIT: I created a foreground service out of it but it still gets terminated.

public class PackingService extends Service { String basePath = ""+ Environment.getExternalStorageDirectory(); String source = basePath+"/data.zip"; File dir = new File(basePath+"/data"); @Override public void onCreate() { super.onCreate(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("Zipping") .setContentText("..."); startForeground(1337, nBuilder.build()); try{ ZipFile zipFile = new ZipFile(source); Log.d("ZIP", "Preparing files..."); ArrayList filesToAdd = new ArrayList(); addDirectory(dir, filesToAdd); ZipParameters parameters = new ZipParameters(); parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE); parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_ULTRA); zipFile.setRunInThread(true); ProgressMonitor monitor = zipFile.getProgressMonitor(); Log.d("ZIP", "Creating zip..."); zipFile.createZipFile(filesToAdd, parameters); int percent = -1; while(monitor.getState() == ProgressMonitor.STATE_BUSY){ if(percent != monitor.getPercentDone()) { percent = monitor.getPercentDone(); Log.d("Progress", percent + "%"); } } } catch (ZipException e) { e.printStackTrace(); } stopForeground(true); return super.onStartCommand(intent, flags, startId); } @Override public IBinder onBind(Intent intent) { return null; } public void addDirectory (File dir, ArrayList filesToAdd) { if (dir.exists()) { File[] files = dir.listFiles(); for (int i = 0; i < files.length; ++i) { File file = files[i]; if (file.isDirectory()) { addDirectory(file, filesToAdd); } else { filesToAdd.add(file); } } } }

Logs:

dalvikvm﹕ threadid=3: reacting to signal 3 dalvikvm﹕ Wrote stack traces to '/data/anr/traces.txt'

解决方案

I solved the problem by not using Service but IntentService. I then put the whole zipping code into the onHandleIntent method of the IntentService and call startForeground before it. After zipping finishes I call stopForeground and everything works perfectly.
