Android如何设置APP开机启动

想让一个apk开启自动运行，可以通过Android系统中的广播机制实现开机自启动。

广播（Broadcast）是Android系统的四大组件之一，通过该机制可以实现不同应用程序之间的通信。

实现Apk开启自启动，进行如下两步操作即可：

1、添加广播接收器文件：

BroadcastReceiver.java

package com.face.detail;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class BootCompleteReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

// TODO: This method is called when the BroadcastReceiver is receiving

// an Intent broadcast.

if(Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())){

Intent thisIntent = new Intent(context, MainActivity.class);

thisIntent.setAction("android.intent.action.MAIN");

thisIntent.addCategory("android.intent.category.LAUNCHER");

thisIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(thisIntent);

}

}

}

2、在AndroidManifest.xml文件中设置接收开机广播权限

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.face.facefeature">

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

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

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

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

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

<!-- .接收启动完成的广播权限 -->

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

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:installLocation="internalOnly"

android:label="@string/app_name"

android:roundIcon="@mipmap/ic_launcher_round"

android:supportsRtl="true"

android:theme="@style/Theme.AppCompat.Light.NoActionBar">

<receiver

android:name=".detail.BootCompleteReceiver"

android:enabled="true"

android:exported="true">

<!--接收启动完成的广播-->

<intent-filter android:priority="1000">

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

<activity android:name=".detail.MainActivity">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

<activity android:name=".detail.Activity" />

<activity android:name=".detail.AuthActivity" />

</application>

</manifest>
