What kind of technology need I use if the function doWork will run a long time

manpreet Best Answer 2 years ago

The function doWork maybe run 20s, I think the system will cause ANR problem. I don't know what kind of technology I need use to prevent ANR, AyncTask, local server, thread, IntentService or others. Could you give me some sample codes? Thanks!

AlarmManagerBroadcastReceiver.java

package com.code4reference.enabledisablebroadcastreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {

  private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";

  @Override
  public void onReceive(Context context, Intent intent) {   
     doWork(context,intent);         
  } 

  private void doWork(Context context, Intent intent){      
     //It will running a long time.
  } 

}

AndroidManifest.xml

    package="com.example.enabledisablebroadcastreceiver"
