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)
