一、 android34升级：
1、升级到安卓34（蓝牙、图片）
再蓝牙广播的地方加入Context.RECEIVER_EXPORTED
2、废弃了 BluetoothAdapter#enable() 和 BluetoothAdapter#disable()，需要修改
// 以前的蓝牙操作BluetoothManager bluetoothManager = (BluetoothManager) this.getSystemService(Context.BLUETOOTH_SERVICE);BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();Log.i(TAG, "BluetoothAdapter isEnabled: " + bluetoothAdapter.isEnabled());if (!bluetoothAdapter.isEnabled()) {boolean enable = bluetoothAdapter.enable();Log.i(TAG, "BluetoothAdapter enable result: " + enable);
}
// 现在需要这样BluetoothManager bluetoothManager = (BluetoothManager) this.getSystemService(Context.BLUETOOTH_SERVICE);BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();Log.i(TAG, "BluetoothAdapter isEnabled: " + bluetoothAdapter.isEnabled());if (!bluetoothAdapter.isEnabled()) {ActivityResultLauncher<Intent> register = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),new ActivityResultCallback<ActivityResult>() {@Overridepublic void onActivityResult(ActivityResult result) {if (result == null) {Log.i(TAG, "开启蓝牙失败：result 为 null");return;}int resultCode = result.getResultCode();if (resultCode != Activity.RESULT_OK) {Log.i(TAG, "开启蓝牙失败：resultCode 为 " + resultCode);return;}Log.i(TAG, "开启蓝牙成功：resultCode 为 " + resultCode);}});Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);register.launch(intent);
}
图片-头像-拍照：
androidmainfest 增加权限： Manifest.permission.READ_MEDIA_IMAGES,
Manifest.permission.READ_MEDIA_VIDEO,
Manifest.permission.READ_MEDIA_VISUAL_USER_SELECTED,
代码中动态请求：
Manifest.permission.READ_MEDIA_IMAGES,
Manifest.permission.READ_MEDIA_VIDEO,
Manifest.permission.READ_MEDIA_VISUAL_USER_SELECTED,
请求权限参考代码
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU&& (ContextCompat.checkSelfPermission(this, READ_MEDIA_IMAGES) == PERMISSION_GRANTED|| ContextCompat.checkSelfPermission(this, READ_MEDIA_VIDEO) == PERMISSION_GRANTED)) {// Android 13及以上完整照片和视频访问权限} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.UPSIDE_DOWN_CAKE &&ContextCompat.checkSelfPermission(this, READ_MEDIA_VISUAL_USER_SELECTED) == PERMISSION_GRANTED) {// Android 14及以上部分照片和视频访问权限} else if (ContextCompat.checkSelfPermission(this, READ_EXTERNAL_STORAGE) == PERMISSION_GRANTED) {// Android 12及以下完整本地读写访问权限} else {// 无本地读写访问权限}

打aab包：
1、将项目中的\app\src\main\assets中的bin文件夹全部移动到base_assets文件夹
2、打包aab:build->Android App Bundle->选择签名，得到aab的包
===============================================
直接AS运行到手机上测试的：
1、需要将base_assets中的\base_assets\src\main\assets的bin文件，拷贝到\app\src\main\assets
2、移除base_assets文件夹
================================================
将aab转换为apks
1、将aab的包拷贝到AAB_TO_APK文件夹（名称默认为app-release.aab），
2、点击click.bat，出来小黑屏，等待apks的生成 (如果无响应的，重新下载bundletool-all-1.18.1的版本、检查jdk的版本)
下载链接：https://github.com/google/bundletool/releases
3、得到出来aa.apks，解压获得apk的文件包
4、安装到手机测试功能
