经典蓝牙双机控制 APP-完整版1

🎯第一步：创建总开关（最重要）

文件：`app/src/main/java/com/bt/BuildConfig.java`

packagecom.bt;/** * 条件编译开关 * true = 服务端（被控端 · 被控制的手机） * false = 客户端（控制端 · 主控手机） */publicclassBuildConfig{// 🔥 只改这里 🔥publicstaticfinalbooleanSERVER_MODE=false;}

📂第二步：完整工程所有文件（全部复制粘贴）

1. 项目根文件

`settings.gradle`

pluginManagement { repositories { google() mavenCentral() } } dependencyResolutionManagement { repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS) repositories { google() mavenCentral() } } rootProject.name = "BtRemoteControl" include ':app'

`build.gradle`（项目级）

plugins { id 'com.android.application' version '8.2.2' apply false }

`gradle.properties`

android.useAndroidX=true android.nonTransitiveRClass=true org.gradle.jvmargs=-Xmx2048m

2. app 模块文件

`app/build.gradle`

plugins { id 'com.android.application' } android { namespace 'com.bt' compileSdk 34 defaultConfig { applicationId "com.bt.remote" minSdk 26 targetSdk 34 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } } dependencies { implementation 'androidx.appcompat:appcompat:1.6.1' implementation 'com.google.android.material:material:1.11.0' }

`app/proguard-rules.pro`

-keep class com.bt.** {*;}

3. 清单文件（自动识别服务/客户端）

`app/src/main/AndroidManifest.xml`

<?xml version="1.0" encoding="utf-8"?><manifestxmlns:android="http://schemas.android.com/apk/res/android"><uses-permissionandroid:name="android.permission.BLUETOOTH"/><uses-permissionandroid:name="android.permission.BLUETOOTH_ADMIN"/><uses-permissionandroid:name="android.permission.BLUETOOTH_SCAN"/><uses-permissionandroid:name="android.permission.BLUETOOTH_CONNECT"/><uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION"/><uses-permissionandroid:name="android.permission.RECEIVE_BOOT_COMPLETED"/><uses-permissionandroid:name="android.permission.FOREGROUND_SERVICE"/><uses-permissionandroid:name="android.permission.CHANGE_WIFI_STATE"/><uses-permissionandroid:name="android.permission.WRITE_SETTINGS"/><uses-permissionandroid:name="android.permission.SYSTEM_ALERT_WINDOW"/><applicationandroid:allowBackup="true"android:label="蓝牙远程控制"android:persistent="true"android:theme="@style/Theme.AppCompat"><activityandroid:name=".MainActivity"android:exported="true"><intent-filter><actionandroid:name="android.intent.action.MAIN"/><categoryandroid:name="android.intent.category.LAUNCHER"/></intent-filter></activity><!-- 客户端 --><activityandroid:name=".client.BluetoothScanActivity"/><activityandroid:name=".client.ControlActivity"/><!-- 服务端 --><activityandroid:name=".server.TargetActivity"/><serviceandroid:name=".server.AccessibilityControlService"android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"><intent-filter><actionandroid:name="android.accessibilityservice.AccessibilityService"/></intent-filter><meta-dataandroid:name="android.accessibilityservice"android:resource="@xml/accessibility_config"/></service><serviceandroid:name=".server.ScreenCaptureService"/><serviceandroid:name=".server.KeepAliveService"/><receiverandroid:name=".server.BootReceiver"android:exported="true"><intent-filter><actionandroid:name="android.intent.action.BOOT_COMPLETED"/></intent-filter></receiver></application></manifest>

🚀第三步：完整 Java 代码（全部齐全）

我把共用、客户端、服务端一次性全部给你！

【共用】Protocol.java

packagecom.bt;publicclassProtocol{publicstaticfinalbyteTOUCH=0x01;publicstaticfinalbyteSYSTEM_CMD=0x02;publicstaticfinalbyteSCREEN_DATA=0x03;publicstaticfinalbyteHEARTBEAT=0x04;publicstaticfinalbyteSYS_VOL_UP=1;publicstaticfinalbyteSYS_VOL_DOWN=2;publicstaticfinalbyteSYS_BRIGHT_UP=3;publicstaticfinalbyteSYS_BRIGHT_DOWN=4;publicstaticfinalbyteSYS_WIFI_TOGGLE=5;publicstaticfinalbyteSYS_BT_TOGGLE=6;publicstaticbyte[]encodeTouch(intaction,intx,inty){returnnewbyte[]{TOUCH,(byte)action,(byte)(x>>8),(byte)(x&0xFF),(byte)(y>>8),(byte)(y&0xFF)};}publicstaticbyte[]encodeSystemCmd(bytecmd){returnnewbyte[]{SYSTEM_CMD,cmd};}}

【共用】BluetoothManager.java

packagecom.bt;importandroid.bluetooth.*;importjava.io.*;importjava.util.UUID;publicclassBluetoothManager{publicstaticfinalUUIDSPP_UUID=UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");privatestaticBluetoothSocketsocket;privatestaticInputStreamin;privatestaticOutputStreamout;privatestaticStringtargetMac;// 服务端publicstaticvoidstartServer(){newThread(()->{try{BluetoothServerSocketss=BluetoothAdapter.getDefaultAdapter().listenUsingRfcommWithServiceRecord("SPP",SPP_UUID);socket=ss.accept();in=socket.getInputStream();out=socket.getOutputStream();startHeartBeat();}catch(Exceptione){}}).start();}// 客户端publicstaticvoidconnect(Stringmac){targetMac=mac;newThread(()->{try{BluetoothDeviced=BluetoothAdapter.getDefaultAdapter().getRemoteDevice(mac);socket=d.createRfcommSocketToServiceRecord(SPP_UUID);socket.connect();in=socket.getInputStream();out=socket.getOutputStream();startHeartBeat();}catch(Exceptione){}}).start();}privatestaticvoidstartHeartBeat(){newThread(()->{while(true){try{send(newbyte[]{Protocol.HEARTBEAT});Thread.sleep(3000);}catch(Exceptione){reconnect();}}}).start();}publicstaticvoidreconnect(){try{Thread.sleep(1000);if(targetMac!=null)connect(targetMac);}catch(Exceptionignored){}}publicstaticvoidsend(byte[]data){newThread(()->{try{if(out!=null)out.write(data);}catch(Exceptionignored){}}).start();}publicstaticInputStreamgetInputStream(){returnin;}}

【主入口】MainActivity.java

packagecom.bt;importandroid.content.Intent;importandroid.os.Bundle;importandroid.widget.TextView;importandroidx.appcompat.app.AppCompatActivity;publicclassMainActivityextendsAppCompatActivity{@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);TextViewtv=findViewById(R.id.tv_mode);if(BuildConfig.SERVER_MODE){tv.setText("模式：被控端（服务端）");startActivity(newIntent(this,com.bt.server.TargetActivity.class));}else{tv.setText("模式：控制端（客户端）");startActivity(newIntent(this,com.bt.client.BluetoothScanActivity.class));}finish();}}
