Could someone provide an hprof which highlights this issue? I'm wondering if com.samsung.android.content.clipboard.SemClipboardManager extends android.sec.clipboard.ClipboardUIManager, given the similarity to the excluded ref found here.

Sorry for opening an old issue, but I've had success in fixing this with the following code in onDestroy in your activities or in a onDestroy in Application.ActivityLifecycleCallbacks:
try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && Build.MANUFACTURER.equals("samsung")) {
Object systemService = getSystemService(Class.forName("com.samsung.android.content.clipboard.SemClipboardManager"));
Field mContext = systemService.getClass().getDeclaredField("mContext");
mContext.setAccessible(true);
mContext.set(systemService, null);
}
} catch (ClassNotFoundException | NoSuchFieldException | IllegalAccessException e) {
//ignored
}

Thank you.. I came across the same issue and used your code, and it seems to work for me as well.

@Jaypeg85 is this safe? At least be sure calling after super.onDestroy() :D
Testencio
on 12 Apr 2018
Yes, of course you need the super.onDestroy, like in all the other snippets.... as for safety, do you mean if the clipboardmanager still works? I have used it for a while, and I havent encountered any issues
Jaypeg85
on 12 Apr 2018
@Jaypeg85 i mean... if samsung changes something in a future this could lead into crashes, right?
Btw... thanks for the fix!
Testencio
on 12 Apr 2018
Yes i suppose it could... Changes in the API would only undo the fix and the exception would be caught though.
Jaypeg85
on 12 Apr 2018
@Jaypeg85 got it, thank you!
Testencio
on 12 Apr 2018
It actually seems it can cause nullpointers, I'll update if I find a fix
Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference

still happens in latest release v1.5.4, do I need to use "master" instead?

Is there a fix for this issue? SemEmergencyManager is leaking on Samsung A tab(T-585).
ibraizQazi
on 13 Sep 2018
There has to be no fix for this it seems. I happen to use this code mentioned by @Jaypeg85 it worked for some Activities but gave below error for Another Activity. Error log is posted here.
I looked at SemClipboardManager class here but I dont seem to understand why mContext is null.

use
mContext.set(systemService, getApplicationContext());
instead of
mContext.set(systemService, null);

Hi guys, sorry for commenting on an already closed thread. I'm having exactly the same issues with Samsung devices running Android 7.0. All logs on fabric are coming from Samsung Galaxy S6.
The error is pointing to ActivityBase where I'm overriding getSystemService. Did anyone found a workaround this issue?
