Android 開發 — 開機自啓動

Android 的開機自啓動是通過捕捉開機結束的廣播來實現的，手機的啓動完後會給出一個BroadcastReceiver，在自己的程序中捕捉即可。

 

AutoBootReceiver.java 文件：

package com.ldq.auto.boot;

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

public class AutoBootReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
			Log.i("------", "AutoBootReceiver auto boot");
			Intent in = new Intent(context, ExAutoBoot.class);
			in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//添加Flags必不可少，否則報錯
			context.startActivity(in);
		}
	}
}

 

 ExAutoBoot.java 文件： 

package com.ldq.auto.boot;

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

public class ExAutoBoot extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i("------","ExAutoBoot auto boot");
    }
}

 

AndroidManifest.xml 文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
	package="com.ldq.auto.boot" android:versionCode="1"
