Android 如何用代码执行 shell 命令

fun doShellReport(cmd: String): Unit {    try {        Logger.error(UploadUtils::class, "doShellReport开始")//        val su = Runtime.getRuntime().exec("su")        val su = Runtime.getRuntime().exec("$cmd\n")        val outputStream = DataOutputStream(su.outputStream)//        outputStream.writeBytes("$cmd\n")//        outputStream.flush()//        outputStream.writeBytes("exit\n")        outputStream.flush()        Logger.error(UploadUtils::class, "doShellReport等待")        su.waitFor()        Logger.error(UploadUtils::class, "doShellReport结束")    } catch (e: Exception) {        e.printStackTrace()        Logger.error(UploadUtils::class, "doShellReport结果: ${e.localizedMessage}")    }}

private val coroutineScope = CoroutineScope(Dispatchers.IO)
private var isRunning = truefun doBugReport(context: Context, cmd: String, callback: BugReportCallback? = null): Unit {    coroutineScope.launch {        try {            Logger.error(UploadUtils::class, "doBugReport开始")            val su = Runtime.getRuntime().exec("$cmd\n")            val outputStream = DataOutputStream(su.outputStream)            val inputStream = DataInputStream(su.inputStream)            val bufferedReader = BufferedReader(InputStreamReader(inputStream))            outputStream.flush()            Logger.error(UploadUtils::class, "doBugReport等待")
            launch(Dispatchers.IO) {                while (isRunning) {                    val result = bufferedReader.readLine()                    Log.e("BugReport", "doBugReport: $result")                    if (result.isNullOrEmpty())                        break                    if (result.containsIgnoreCase(END_STRING)) {                        break                    }                }                callback?.onResult(true)                inputStream.close()            }            su.waitFor()            outputStream.close()            Logger.error(UploadUtils::class, "doBugReport结束")        } catch (e: Exception) {            e.printStackTrace()            Logger.error(UploadUtils::class, "doBugReport异常: ${e.localizedMessage}")        }    }}
