TfLiteGpuDelegate Invoke: GpuDelegate must run on the same thread where it was initialized

I am trying to run a custom Tflie model for segmentation in Android. It runs fine on CPU but while using GPU delegate, it crashes with following error:-

Here is my code to load model
MappedByteBuffer buffer = null;
buffer = FileUtil.loadMappedFile(context, "docScan.tflite");
int numThreads = 4;
boolean useGpuDelegate = true;
final Interpreter.Options tfliteOptions = new Interpreter.Options();
tfliteOptions.setNumThreads(numThreads);
if (useGpuDelegate){
GpuDelegate delegate = new GpuDelegate();
tfliteOptions.addDelegate(delegate);
}
tfLite = new Interpreter(buffer, tfliteOptions);
Strangely, it works on phones like MI/Redmi/OPPO and only crashes on Samsung. Please help!

Add the following lines to AndroidManifest.xml:

Collections.sort causing java.lang.SecurityException: Requires READ_PHONE_STATE

I am getting the crash below at this code line:
pkgMrg_global = getActivity().getPackageManager();
apps = pkgMrg_global.getInstalledApplications(0);
//GETTING CRASH AT LINE BELOW
Collections.sort(apps,
new ApplicationInfo.DisplayNameComparator(
pkgMrg_global));
What I dont understand is how Collections.sort leads to this Caused by: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10157 nor current process has android.permission.READ_PHONE_STATE?

As per google docs here
The note says
Note: If both your minSdkVersion and targetSdkVersion values are set to 3 or lower, the system implicitly grants your app this permission. If you don't need this permission, be sure your targetSdkVersion is 4 or higher.
Protection level: dangerous
if so you need to add the permission
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
Constant Value: "android.permission.READ_PHONE_STATE"

add this permission to your android manifest
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

You must add this permission in your AppManifest.xml:
<uses-permission android:name="android.permission.CALL_PHONE" />
Your error occurred because you didn't add it.

Since the logcat is saying everything what you looking for why dont you try to add permission ?
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

You seem to have an intent which makes an call but however for any app to make a call it requires the permission.
To add it in the Manifest before the application tag add the following
<uses-permission android:name = "android.permission.CALL_PHONE"/>

SecurityException: Permission Denial: opening provider (fatal exception: asynctask #3)

I am building an Android Library. I kept the code as normal android project while I was developing it and now I converted it into library project (even made a new library project and copied all the code in there just to be sure). The library basically allows user to enter data into database using contentprovider and the library returns that data queried from the database. So whatever app uses the library does not need to use the contentprovider to access data since the library does it all.
I made a very basic app that uses the library, the moment that I make a call to the library the app crashes giving the error code:

I added permissions to testapp, but didnt change the error
<uses-permission android:name="thesis.thesis.contentprovider.READ_DATABASE" />
<uses-permission android:name="thesis.thesis.contentprovider.WRITE_DATABASE" />
The provider declared in library manifest:
<provider
android:name="thesis.thesis.contentprovider.UsersDataContentProvider"
android:authorities="thesis.thesis.contentprovider"
android:exported="true"
android:readPermission="thesis.thesis.contentprovider.READ_DATABASE"
android:writePermission="thesis.thesis.contentprovider.WRITE_DATABASE" />
At the moment I have exported="true" to see if that was the problem but no. Later I want it to be set false, since the data is sensitive.
Can anyone please direct me to where the problem might be. Also ask if additional information is needed.

can you help me? Thanks

The clue is
Caused by: java.lang.SecurityException: Permission Denial: getCurrentUser() from pid=2228, uid=10011 requires android.permission.INTERACT_ACROSS_USERS
You need to add to your manifest.xml
<uses-permission android:name="android.permission.INTERACT_ACROSS_USERS" />
That being said, I've not seen this permission before... I believe it's used when you require root access. So you also might need a phone that is rooted.
