java.io.FileNotFoundException: /data/system/theme_config/theme_compatibility.xml (No such file or directory) #1116

This error is harmless, see #994. It is not printed anymore (on the development branch). Besides this, does scrcpy work normally? (If not, it is probably unrelated.) |

My script uses `AndroidViewClient` but cannot create a `ViewClient`
```python3
from com.dtmilano.android.viewclient import ViewClient
def createViewClient():
return ViewClient(*ViewClient.connectToDeviceOrExit(serialno='.*'))
vc = createViewClient()
```
The script returns the following stack trace:
```sh

When I execute the command `adb shell uiautomator dump` on my device a Pocophone X3 with MIUI 12 installed, I get the following result:
```sh

UI hierchary dumped to: /sdcard/window_dump.xml
```
So `uiautomator` throws an error, but still succeeds to dump the XML. The constructor of `ViewClient` calls `parser.Parse(receivedXml[start_xml_index:end_xml_index + 1])` [Ln 3323](https://github.com/dtmilano/AndroidViewClient/blob/master/src/com/dtmilano/android/viewclient.py#L3323), but the XML contained in `received` cannot be parsed because it still contains parts of the exceptions: `start_xml_index = receivedXml.index("<")` will return the first index of '<', which is in the exception (`java.io.FileInputStream.<init>`).
We fixed the issue by filtering out the exception from the `received` variable [Ln 3461](https://github.com/dtmilano/AndroidViewClient/blob/master/src/com/dtmilano/android/viewclient.py#L3460):
```python3
received = re.sub(re.compile('java.io.FileNotFoundException.*<\?xml', re.DOTALL),'<?xml', received)
```
But it would probably be cleaner to replace the value of `start_xml_index = receivedXml.index("<")` with `start_xml_index = receivedXml.index("<?xml")`.
@dtmilano What do you think? Would you be interested by a pull request?
Note that this error is similar to two issues in the `scrcpy` project:
- Genymobile/scrcpy#1116
- Genymobile/scrcpy#994
These issues were fixed by just ignoring the exceptions (see Genymobile/scrcpy@96bd2c9).

Hi,
I am getting the next error when I run scrcpy.exe (on Windows 10).
How can I resolve this issue?
Thanks & Regards.
