Android开发APP自启动

1、先在AndroidManifest.xml文件中定义广播和声明权限

manifest节点属性：android:installLocation="internalOnly"（安装至内部存储）
application节点内：
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="true">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>

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

2、在主java文件旁新建MyReceiver.java，代码如下：

package cn.flashme.APP包名;

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

public class MyReceiver extends BroadcastReceiver
{
    public MyReceiver()
    {
    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
        {
            Intent i = new Intent(context, MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}
