Android 10+ android.permission.NETWORK_STACK for hidden api

I am testing a new app on a physical device:
REDMI NOTE 9 PRO
android 10
MIUI 12
I am trying to access to startSoftAp that is a hidden method of WifiManager class. That is I want programmatically start and stop tethering.
Following this approach and many other links such as:
https://www.xda-developers.com/android-development-bypass-hidden-api-restrictions/
https://www.reddit.com/r/androiddev/comments/deyz14/apparently_you_can_destroy_hidden_api_blacklist/
I am facing a new issue regarding
android.permission.NETWORK_STACK
that I am not able to fix. The main cause is
Caused by: **java.lang.SecurityException: WifiService: Neither user
10448 nor current process has android.permission.NETWORK_STACK.
Obviously I tried to specify this via manifest file but this is a non-SDK permission or hidden permission. Then them method described by many programmer to bypass hidden API seems is missing something about this permission.
Here is the stack trace.

I am working on the production app. I am receiving the exception in Crashlytics. I don't have a clue where is happening because it is not pointing any activity. Just I am getting an error like this.

I'm developing app in android and for some reason I'm receiving this error.
I did not change any code line and suddenly I'm getting this error.
I have no idea what should i do, its not even pointing where the problem is.

Any idea why is it crashing?

AudioRecord is not initialized, its null, you can see e in the first line
02-22 20:22:42.863 4637-5379/? E/AudioProvider: AudioRecord is null, can't start recording

Their is some mistake in layout/.xml file i.e designing part, check that properly.
In my case i got it because i was VerticalViewPager in main activity but in xml i passed it as viewpager.

Can't create SensorDirectChanel

Since API 26 SensorDirectChannel is available to use for possible faster sample rates.
It can be used with MemoryFile or HardwareBuffer as Buffer.
I get IOExceptions with both while trying to create the Channel. I tried as following:
SensorManager sm = (SensorManager)getSystemService(Service.SENSOR_SERVICE);
MemoryFile memFile = null;
try {
memFile = new MemoryFile("AccMemoryFile", 1040);
} catch (Exception e) {
e.printStackTrace();
}
SensorDirectChannel channel = sm.createDirectChannel(memFile);
I get the following message:

As there are no examples or other documentation for the usage of Direct Channels I am not sure if I maybe missed something. I tried it on a real and a virtual device, both running Oreo 8.1 (API 27).
I looked a little bit into the native function but i could not find a reason.I also could not figure out what the -12 means.
I hope someone can clarify this.
Thanks in advance

bro, I think the reason that cause this issue is that your device doesn't support SensorDirectChannel.
I recently encountered a similar problem that I can't create a SensorDirectChannel by passing a MemoryFile instance with almost same Logcat information as what you got, but I CAN have it done by passing a HardwareBuffer instance, weird.
After checking some docs I found the reason from this site.
And the item 7.3.9 say:
Blockquote
If device implementations include direct sensor support, they:
[C-3-1] MUST correctly declare support of direct channel types and direct report rates level through the isDirectChannelTypeSupported and getHighestDirectReportRateLevel API.
[C-3-2] MUST support at least one of the two sensor direct channel types for all sensors that declare support for sensor direct channel
TYPE_HARDWARE_BUFFER
TYPE_MEMORY_FILE
SHOULD support event reporting through sensor direct channel for primary sensor (non-wakeup variant) of the following types:
TYPE_ACCELEROMETER
TYPE_ACCELEROMETER_UNCALIBRATED
TYPE_GYROSCOPE
TYPE_GYROSCOPE_UNCALIBRATED
TYPE_MAGNETIC_FIELD
TYPE_MAGNETIC_FIELD_UNCALIBRATED
So, obviously the sensor vendor must make their sensor support the TYPE_HARDWARE_BUFFER SensorDirectChannel or TYPE_MEMORY_FILE SensorDirectChannel or both of them, or you cannot make use of them.
At last, I check the acceleration sensor of my device (Pixel2) via isDirectChannelTypeSupported and got an expected result as follows:
resultscreenshot.
Hope it can help you.
Btw, my English is not so good. Apologize if it makes you confused.

DeadObjectException thrown by queryIntentActivities

I'm getting the DeadObjectException from queryIntentActivities rarely.
This is all I found for this issue: http://comments.gmane.org/gmane.comp.handhelds.android.acra/184 So I tried to adjust my code like following (comment in this code is derived from the post mentioned above).
I'm trying following:
Old code
List<ResolveInfo> ril = pm.queryIntentActivities(mainIntent, 0);
New code
List<ResolveInfo> ril = null;
try
{
ril = pm.queryIntentActivities(mainIntent, 0);
// process data...
}
catch (DeadObjectException e)
{
// possibly happens because this process is still running but app is currently being updated by the android system
// if this is really true, we can ignore the exception as the complete progress will be stopped anyways...
L.e(e);
}
Problem
I can't catch the exception, because by definition it is never thrown by queryIntentActivities. What can I do instead now to avoid this crash? I don't want to catch all exceptions here.
Additionally I'm not sure if this exception really only happens, I've my app is updated while trying to call queryIntentActivities, it's just an assumption based on the post above. Can anyone confirm this?
