红米k40手机，MUI系统，Android SDK 33版本，也是提示不支持不支持perfetto，让增加-mode simple后抓取trace可以查看

[livelitoday]

Android设备情况：Android SDK33 系统: MIUI: 14.0.8 红米K40

使用的命令：

java -jar rhea-trace-shell.jar -a rhea.sample.android -t 5 -o output.pb -r rhea.all sched -fullClassName

输出结果：

02-02 13:43:06.512 I RheaTrace : os version is 33. default capture is PerfettoCapture
02-02 13:43:08.525   RheaTrace : start tracing...
02-02 13:43:13.815   RheaTrace : stop tracing...
02-02 13:43:13.998   RheaTrace : MaxAppTraceBufferSize usage 820096/500000000 (0%)
02-02 13:43:14.137 E RheaTrace : Error: systrace file not found: rheatrace.workspace\systemTrace.trace
02-02 13:43:14.137 E RheaTrace :  Tips: your device may not support perfetto. please retry with `-mode simple`.

另外！！！使用perfetto命令行，能获取到trace文件并从Perfetto网站打开查看！！使用的命令如下：

adb shell perfetto --out /data/misc/perfetto-traces/traces-wm wm am input gfx view res pm dalvik ss

用户权限：可获取到root权限的设备。

版本：

rhea_gradle_plugin_vesion=2.0.1
implementation 'com.bytedance.btrace:rhea-core:2.0.0'
apk是release版本，是通过反射调用android.os.Trace#setTracingEnabled(true)拿到自定义tag。

麻烦加上 -debug 参数再试一下，提供更详细的 debug 日志我们更好排查一点。
