一、通过adb发送指令，收集设备日志并保存

二、UI

三、代码

    /**
     * 获取设备列表
     */
    fun getDevices(): List<String> {
        val process = ProcessBuilder("adb", "devices")
            .redirectErrorStream(true)
            .start()
        val output = process.inputStream.bufferedReader().readText()
        process.waitFor()
        return output.lines()
            .drop(1)
            .filter { it.isNotBlank() && it.contains("device") }
            .map { it.split("\t").first() }
    }

   //抓取日志
fun startLogcat(device: String) {
        //清除历史
        ProcessBuilder("adb", "-s", device, "logcat", "-c")
            .redirectErrorStream(true)
            .start()
            .waitFor()

        val process = ProcessBuilder("adb", "-s", device, "logcat")
            .redirectErrorStream(true)
            .start()
        logcatProcess = process
        logs.clear()

        scope.launch(Dispatchers.Default) {
            BufferedReader(InputStreamReader(process.inputStream, Charsets.UTF_8)).useLines { lines ->
                lines.forEach { line ->
                    if (filterKeyword.isBlank() || line.contains(filterKeyword, ignoreCase = true)) {
                        logs.add(line)
                        if (logs.size > MAX_LINES) logs.removeFirst()
                    }
                }
            }
        }
    }
