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 }

Same here with s8+ (7.0)

Does anybody know if this was already reported to Samsung?

SemEmergencyManager leaking aswell in my app (Galaxy S6). Updated to Nougat last night

davidevaliante on May 19, 2017

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.
