Question

我正在研究Android应用程序，我只是想当我关闭设备时，当我再次启动我的设备我的应用程序应该自行启动，是否有可能到android？如果是，请帮助，任何帮助将是非常感谢。谢谢。

我的自定义广播接收器类：

package com.whizpool.nogademo;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class PowerEventReceiver extends BroadcastReceiver {

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

    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
        Intent i = new Intent(context, MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }

}
}

Answer 1

使用广播android.intent.action.BOOT_COMPLETED在您的清单中注册广播接收器。然后在onReceive（）方法中，您可以完成必要的逻辑工作。这将需要权限android.permission.RECEIVE_BOOT_COMPLETED。

Answer 2

添加了一个接收器，用于处理电源事件并在此

中开始您的活动

public class PowerEventReceiver extends BroadcastReceiver {

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

            if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
                Intent i = new Intent(context, HeliosActivity.class);
                i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(i);
            }

        }
    }

并将其添加到您的清单

  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

       <receiver android:name="com.RareMediaCompany.Helios.PowerEventReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.ACTION_SHUTDOWN" />
            </intent-filter>
        </receiver>
