Android Automator：是否可以在下载文件夹中附加文件？

Question

我已阅读 Kotlin 附加到文件 线程，我的 UIAutomator 代码如下所示：

fun appendLog(text: String?) {
    val logFile = File("/sdcard/Download/autotest.log")
    if (!logFile.exists()) {
        try {
            logFile.createNewFile()
            Log.d(TAG, "Create new file $logFile Succeed!")
        } catch (e: IOException) {
            Log.e(TAG, "Create new file $logFile FAILED!, $e")
        }
    }
    try {
        FileOutputStream(logFile, true).bufferedWriter().use { writer ->
            writer.append(text)
            writer.newLine()
        }
    } catch (e: IOException) {
        Log.e(TAG, "Appending file $logFile FAILED!, $e")
    }
}

// test cas 1
appendLog("Some test result")

// test cas 2
appendLog("Other test results")

但从 adb 收到错误日志猫
