I'm developing on Android 5.0 now, and I get these logs several times just after the device rebooted in low-power state(I'm not sure if low-power is relevant here).
I don't familiar with SQLite, but I have gone through the flow of ext4 file create, read, and how does selinux label the inode, and I don't see how can a ext4 file inode's xattr be corrupted.
In normal, it should appear like this:
u:object_r:system_data_file:s0 locksettings.db-shm
u:object_r:system_data_file:s0 locksettings.db-wal
I'll paste logs later.
Any help is appreciated..Thank you

I am trying to make an application with QML and C++ for Android on Qt6. I used a sample code from Qt help segment for checking if the camera works or not (see the code segment). I have implemented C++ just for loading the QML file.
My problem is the camera does not show up in the app, I am using Android 10 phone as test device.
import QtQuick
import QtMultimedia
Item {
width: 640
height: 360
CaptureSession {
camera: Camera {
id: camera
focusMode: Camera.FocusModeAutoNear
customFocusPoint: Qt.point(0.2, 0.2) // Focus relative to top-left corner
}
videoOutput: videoOutput
}
VideoOutput {
id: videoOutput
anchors.fill: parent
}
}
The error I face is following. Please help me with this.

I have created directory "vendor/qcom/sepolicy/acm/" and made its entry in BoardConfig.mk as shown below.
# ACM features belong in vendor/qcom/sepolicy

Also I have commented in "device/qcom/sepolicy/common/file_contexts"

I have changed sepolicy in following directories:
[1] vendor/qcom/sepolicy/acm/file_contexts
# These are the ports used to talk.
# We have to relabel these because domain.te has never allow rules that prevent
# any other domain (other than init or ueventd) from accessing these files

allow untrusted_app serial_ic:chr_file { read write };
[6] vendor/qcom/sepolicy/acm/system_app.te
#allow acm node
allow system_app serial_ic:chr_file { ioctl open read write};
Still I am not able to resolve "write" sepolicy error.Whenever from my serial chat application it tries to access node "/dev/ttyGS0" application crashes.

I have a sdk which has some native code. I am building the code into the shared libraries manually and copied those .so files to jniLibs folder. And I am using that sdk in an App. It was working fine with 5, 6 but with Nougat, it just got crashed every time I opened the App.
Note: I have updated the target version to 25 in the build.gradle file.
This is the error Log:

I have searched about this but ended up with no clue.
Someone please help. Thanks in advance.
First of all, there's no problem with iOS, but the problem occurs when the app is running on Androids.
There's a BLE device that does pair / notification / write / read.
It seems all good until other bluetooth devices are connected and paired or synced.
For example, if the android phone is restarted (or Bluetooth is off and on again), my BLE device works great with the app.
If I open fitbit app and sync a fitbit device, then my device cannot connect anymore. (and not pairing as well)
Not only for fitbit but also for samsung smart watch, the same thing happens.
Anyone recommendation will be appreciated.
Tested with Android 6. Samsung GS6 and Nexus 5.
Update 1:
After synced with fitbit, I get the following messages from my app when connecting to my device.

After this, it does one more reading then disconnected.
If I goto bluetooth app and 'clear data', then it works fine again.
This error happened occasionally when I did some user/stress test on Android. Files under /data disapppeared and system server crashed after this error occurred. I am curious about the name of database "contacts2.db-mj7742599A4". Normally it should be contacts2.db. What does "*.db-mj7742599A4" mean? Anyone can help please?
