Bazen bu hata açık bir çağrı yapılmadan ortaya çıkabilir startActivity(...)
. Örneğin, bazılarınız Crashlytics'te böyle bir yığın izini görmüş olabilirsiniz:
Fatal Exception: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

Ne yaptığınızı merak edebilirsiniz, çünkü izleme yalnızca çerçeve kodunu içerir. İşte bunun nasıl olabileceğine bir örnek. Diyelim ki bir parçadayız.
Activity activity = getActivity();
Context activityContext = activity;
Context appContext = activityContext.getApplicationContext();
LayoutInflater inflater = LayoutInflater.from(appContext); // whoops!
View view = inflater.inflate(R.layout.some_layout, parent, false);
TextView tvWithLinks = (TextView) view.findViewById(R.id.tv_with_links);
tvWithLinks.setMovementMethod(LinkMovementMethod.getInstance()); // whoops!!
Artık bir kullanıcı bu metin görünümünü tıkladığında, uygulamanız yukarıdaki yığın izlemesiyle kilitlenecektir. Bunun nedeni mizanpaj şişiricisinin uygulama içeriğine bir başvurusu olması ve bu nedenle metin görünümünüzün bir uygulama içeriğinin olmasıdır. Bu metin görünümünü tıklamak dolaylı olarak çağırır appContext.startActivity(...)
.
Son not: Bunu Android 4, 5, 6 ve 7 cihazlarda test ettim. Sadece 4, 5 ve 6'yı etkiliyor. Android 7 cihazlarının arama yapma konusunda hiçbir sorunu yok appContext.startActivity(...)
.
Umarım bunun bir başkasına yardımı olur!
