我有一个intent服务正在处理长时间运行的任务。但是,如果发生异常,处理时会让SocketTimeOutException服务停止。如何捕获异常并重新启动过程。如何重新启动Android IntentService
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
@Override
protected void onHandleIntent(Intent intent) {
String name = intent.getStringExtra("name");
String packageName = intent.getStringExtra("packageName");
String path = intent.getStringExtra("path");
int downloadedSoFar = 0;
Intent i = new Intent(getApplicationContext(), DownloadListViewApp.class);
PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, i, 0);
nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle(name)
.setContentText("Download in progress")
.setSmallIcon(R.drawable.logo).setContentInfo("0%").setContentIntent(pi);
mBuilder.setOngoing(true);
try {
url = new URL(IPClass.SERVERIP + path + "/" + packageName);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setReadTimeout(7000);
int fileLength = connection.getContentLength();
connection.connect();
input = connection.getInputStream();
output = new FileOutputStream("/sdcard/Android/appdata/tmp/downloadtmp/" + packageName, true);
byte data[] = new byte[1024];
int count;
boolean continueLoop = true;
while ((count = input.read(data)) > 0 && continueLoop) {
progressChange((int) (downloadedSoFar * 100L)/fileLength, packageName);
downloadedSoFar = downloadedSoFar + count;
output.write(data, 0, count);
}
} catch (IOException ex) {
ex.printStackTrace();
} finally {
try {
if (output != null) output.close();
if (input != null) input.close();
} catch (IOException ignored) {
}
if (connection != null) {
connection.disconnect();
}
}
但我想要一个按钮先点击,然后再做任何事情。所以它的活动 - >服务事件(巴士事件不工作)有什么想法? – ralphgabb
