android app启动,android怎么启动

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>
