重启时启动警报管理器应用程序

标签： android broadcastreceiver alarmmanager android-alarms autostart

目前，我正在开发应用程序，可在选定的时间将手机设置为振动模式或振铃模式。我已经在我的应用程序中使用alarmmanager成功实现了这一点。 我希望我的应用程序在重新启动手机时记住所有待处理的意图。 我在互联网上找到了一个示例代码，但是当手机重启时，它似乎会崩溃我的应用程序。我不知道出了什么问题。

这是alarmreciever.java 

package ishan.khandelwal.vitsilentmode;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.widget.Toast;

public class AlarmReciever extends BroadcastReceiver
{
private AudioManager mAudioManager;

@Override
        public void onReceive(Context context, Intent intent)
        {
                // TODO Auto-generated method stub

        if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
        Intent serviceIntent = new Intent("ishan.khandelwal.vitsilentmode");
        context.startService(serviceIntent);
        }   

        mAudioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
        mAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

        // Show the toast
        Toast.makeText(context, "Vibration Mode", Toast.LENGTH_SHORT).show();

          }
}

好的，问题是您在AndroidManifest中指定了错误/不存在的接收器实现。你指定了这个：

<receiver
android:name=".receiver.StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
 <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>

问题是你没有名为StartMyServiceAtBootReceiver的类。你认为你应该拥有的是这样的：

<receiver
android:name=".AlarmReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
 <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
