Firefly RK3399杂记

1.实现APP开机自启动

新建一个类继承BroadcastReceiver

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

public class AutoStartAppReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED")){

            Intent intent2 = new Intent(context, MainActivity.class);
            intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intent2);
        }
    }
}

此处类为AutoStartAppReceiver，将此广播接收器在AndroidManifest中注册，如下所示。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.cz.bluetoothchatterfromgoogletest">
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/schoollogo"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:ignore="GoogleAppIndexingWarning">
        <activity
            android:name="com.example.cz.bluetoothchatterfromgoogletest.android.bluetoothchat.MainActivity"
            android:configChanges="orientation|keyboardHidden"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER"  />
            </intent-filter>
        </activity>

        <activity
            android:name="com.example.cz.bluetoothchatterfromgoogletest.android.bluetoothchat.DeviceListActivity"
            android:configChanges="orientation|keyboardHidden"
            android:label="@string/select_device"
            android:theme="@android:style/Theme.Holo.Dialog"/>

        <service android:name="org.eclipse.paho.android.service.MqttService" />

        <receiver android:name=".android.bluetoothchat.AutoStartAppReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

</application>

</manifest>

同时里面需要添加权限。

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

即可实现APP开机自启。

2.RK3399开机之后若是把蓝牙打开，则之后重启仍会开启蓝牙。同时可以设置静态IP。
