看代码学Android ：APP开机自启动

TestActivity1.java

package com.test;

import android.app.Activity;
import android.os.Bundle;

public class TestActivity1 extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

BootReceiver.java

package com.test;

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

public class BootReceiver extends BroadcastReceiver {

    static final String ACTION = "android.intent.action.BOOT_COMPLETED";

    @Override
    public void onReceive(Context context, Intent intent) {
        // receive ACTION_BOOT_COMPLETED intent, start your activity, Magic code cool!
        if (intent.getAction().equals(ACTION)) {
            Intent testIntent = new Intent(context, TestActivity1.class);
            testIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(testIntent);
        }
    }

}

AndroidMainfest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""
    package="com.test" android:versionCode="1" android:versionName="1.0">
    <!--  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission> -->

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestActivity1" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name="BootReceiver"
            android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"></action>
            </intent-filter>
        </receiver>

    </application>
</manifest>

经我试验可以申请权限有两种方法，都可以。另一种在receiver 中加。

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