Question

我正在尝试创建一个应用程序，该应用程序会定期自动拨打电话到指定的号码。我为此目的使用了Alarm Manager和Broadcast Receiver。警报管理器无法启动PHONE CALL活动，应用程序终止会发出错误。

这是我的代码。我是这个Dev的新手。

* MainActivity.java

#!/bin/bash
#Backup:
asbackup -h localhost -n test  -d /home/asif/aerobckups -r

#Restore:
asrestore -d /home/asif/aerobckups

* AlarmReceiver.java

0 0 * * 4 /home/ramesh/backup.sh

问题已解决。

我使用了Flag＆＃34; FLAG_ACTIVITY_NEW_TASK＆＃34;具有AlarmReceiver类的意图。

新代码如下

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.Toast;

/**
 * Created by Saud on 05/11/2015.
 */
public class AlarmReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent arg1) {
        // For our recurring task, we'll just display a message
       Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
       // Intent in = new Intent(Intent.ACTION_CALL);
        //in.setData(Uri.parse("tel:03324310929"));
        Intent in = new Intent(Intent.ACTION_CALL);
        in.setData(Uri.parse("tel:03324310929"));
        in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(in);


    }

}

使用Alarm Manager＆amp;广播接收器
