Android 15设备启动前台服务触发SecurityException崩溃问题

崩溃错误信息

由java.lang.SecurityException引起：启动类型为microphone的前台服务（FGS），调用应用ProcessRecord{6d0f21f 24588:com.app.freeboomshare/u0a271}，targetSDK=34，需要满足以下权限要求：必须拥有所有allOf=true的权限[android.permission.FOREGROUND_SERVICE_MICROPHONE]，且拥有任意一个allOf=false的权限[android.permission.CAPTURE_AUDIO_HOTWORD, android.permission.CAPTURE_AUDIO_OUTPUT, android.permission.CAPTURE_MEDIA_OUTPUT, android.permission.CAPTURE_TUNER_AUDIO_INPUT, android.permission.CAPTURE_VOICE_COMMUNICATION_OUTPUT, android.permission.RECORD_AUDIO]，同时应用必须处于符合条件的状态/豁免范围才能访问前台专属权限

背景信息

应用已上线Google Play，通过MediaProjection + 前台服务实现屏幕和音频录制功能，targetSdkVersion设为34。崩溃发生在启动前台服务后、屏幕录制开始前。

AndroidManifest.xml权限配置

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> 
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PROJECTION" /> 
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MICROPHONE" /> 
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_DATA_SYNC" /> 
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" /> 
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> 
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_CAMERA" />

已尝试方案

确认RECORD_AUDIO和FOREGROUND_SERVICE权限已通过运行时授权
添加Android 15（UpsideDownCake）适配的前台服务启动逻辑：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.UPSIDE_DOWN_CAKE) { 
    // 同时录制屏幕、音频和摄像头
    val serviceTypes = ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION or 
                      ServiceInfo.FOREGROUND_SERVICE_TYPE_MICROPHONE or 
                      ServiceInfo.FOREGROUND_SERVICE_TYPE_CAMERA 
    startForeground(1, notification, serviceTypes) 
} else { 
    startForeground(1, notification) 
}

Fragment核心代码

private fun startRecording() {
    val mediaProjectionManager = requireActivity().getSystemService(AppCompatActivity.MEDIA_PROJECTION_SERVICE) as MediaProjectionManager
    startActivityForResult(mediaProjectionManager.createScreenCaptureIntent(), REQUEST_CODE)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == REQUEST_CODE) {
        if (resultCode == AppCompatActivity.RESULT_OK && data != null) {
            RecordingUtils.startCountdown(viewBinding.countdownText) {
                viewBinding.btStopRecording.visibility = View.VISIBLE
                val serviceIntent = Intent(
                    requireActivity(),
                    ScreenCameraReordingService::class.java
                )
                serviceIntent.action = ACTION_START_RECORDING
                serviceIntent.putExtra(EXTRA_RESULT_CODE, resultCode)
                serviceIntent.putExtra(EXTRA_RESULT_DATA, data)
                serviceIntent.putExtra("isAudioRecordingON", isAudioRecordingON)
                serviceIntent.putExtra("isCameraRecordingON", isCameraRecordingON)
                ContextCompat.startForegroundService(requireActivity(), serviceIntent)
                disableToggles()
            }
        } else {
            viewBinding.btStartRecording.visibility = View.VISIBLE
            viewBinding.btStopRecording.visibility = View.GONE
            viewModel.startScreenRecordingClickLiveData.value = false
            Toast.makeText(requireActivity(), "Screen capture permission denied", Toast.LENGTH_SHORT).show()
        }
    }
    /*else if (requestCode == REQUEST_CODE_OVERLAY && resultCode == AppCompatActivity.RESULT_OK){
        val intent = Intent(requireContext(), ScreenCameraReordingService::class.java).apply {
            action = ScreenCameraReordingService.ACTION_START_OVERLAY
        }
        requireContext().startForegroundService(intent)
    }*/
}

问题分析与修复方案

核心问题

Android 15对前台服务的权限验证逻辑更严格：启动包含MICROPHONE类型的前台服务时，除了声明FOREGROUND_SERVICE_MICROPHONE权限，还需满足两个关键条件：

必须持有RECORD_AUDIO（或其他指定音频权限）的运行时授权
服务启动必须由即时用户交互触发（比如直接点击按钮，而非延迟操作）

另外你的Manifest中缺少RECORD_AUDIO权限声明，这是运行时授权的前提。

具体修复步骤

补全Manifest权限声明
在Manifest中添加RECORD_AUDIO权限：

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

提前检查并请求必要权限
在调用startRecording()前，先检查并请求录音、摄像头权限，确保授权完成后再进入流程：

private fun checkPermissionsAndStart() {
    val requiredPermissions = mutableListOf<String>()
    // 检查录音权限
    if (isAudioRecordingON && ContextCompat.checkSelfPermission(requireActivity(), Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
        requiredPermissions.add(Manifest.permission.RECORD_AUDIO)
    }
    // 检查摄像头权限
    if (isCameraRecordingON && ContextCompat.checkSelfPermission(requireActivity(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
        requiredPermissions.add(Manifest.permission.CAMERA)
    }
    if (requiredPermissions.isNotEmpty()) {
        ActivityCompat.requestPermissions(requireActivity(), requiredPermissions.toTypedArray(), REQUEST_PERMISSION_CODE)
    } else {
        startRecording()
    }
}

在onRequestPermissionsResult中处理授权结果，通过后再执行startRecording()。

按需配置前台服务类型
根据实际录制需求动态设置serviceTypes，避免添加不需要的类型触发额外权限检查：

val serviceTypes = buildList {
    add(ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION)
    if (isAudioRecordingON) add(ServiceInfo.FOREGROUND_SERVICE_TYPE_MICROPHONE)
    if (isCameraRecordingON) add(ServiceInfo.FOREGROUND_SERVICE_TYPE_CAMERA)
}.reduce { acc, type -> acc or type }
startForeground(1, notification, serviceTypes)

确保服务启动时机符合要求
Android 15要求前台服务必须由即时用户交互触发，建议将前台服务启动逻辑调整到用户点击"开始录制"的直接回调中，避免通过倒计时等延迟操作触发。如果必须保留倒计时，需确保倒计时的触发紧接用户操作，且倒计时时长不宜过长。
