Android实现开机自动启动APP

public class BootBroadcastReceiver extends BroadcastReceiver {
    static final String ACTION = "android.intent.action.BOOT_COMPLETED";

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION)) {
            Intent intent = new Intent(context, MainActivity.class);  // 要启动的Activity  
            //1.如果自启动APP，参数为需要自动启动的应用包名 
   			//Intent intent = getPackageManager().getLaunchIntentForPackage(packageName); 
 			//下面这句话必须加上才能开机自动运行app的界面  
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			//2.如果自启动Activity
            //context.startActivity(intent);
			//3.如果自启动服务
			context.startService(intent);
        }
    }
}
