defaultConfig {
applicationId "sampleapp.app"

You should use the new support design library NavigationView:
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/black"
app:itemTextColor="#color/drawer_item_color_selector"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/menu_drawer"/>

Crash in Google Maps caused by a null pointer in android.widget.EdgeEffect.<init>

I've been seeing a crash on the ZTE Z993 (Android 4.1.1) that occurs in apps that use a MapView or SupportMapFragment (e.g. Lyft, Yelp, Airbnb). It looks like the crash occurs in the initialization of EdgeEffect within a ListView that Google Maps uses. The link below points to a git repo that reproduces the crash. I've also included the stacktrace. Has anyone seen this? Can anyone suggest a fix? Thanks!

direct event insert to attendees table exceotion if sdk versio lower than 19

I am building an application in which I am inserting events directly to the calendar plus I left the possibility to invite someone else and everything is perfectly fine if I execute it on android sdk version 19 and above, on lower versions I get an exception.
Here is the source:
ContentResolver atend = getContentResolver();
ContentValues val = new ContentValues();
val.put(CalendarContract.Attendees.ATTENDEE_NAME, "Bajo");
val.put(CalendarContract.Attendees.ATTENDEE_EMAIL, someonesEmail);
val.put(CalendarContract.Attendees.ATTENDEE_RELATIONSHIP, CalendarContract.Attendees.RELATIONSHIP_ATTENDEE);
val.put(CalendarContract.Attendees.ATTENDEE_TYPE, CalendarContract.Attendees.TYPE_REQUIRED);
val.put(CalendarContract.Attendees.ATTENDEE_STATUS, CalendarContract.Attendees.ATTENDEE_STATUS_INVITED);
val.put(CalendarContract.Attendees.EVENT_ID, eventID);
Uri muri= atend.insert(CalendarContract.Attendees.CONTENT_URI, val);
Log.d("Atendees URI:",muri.toString());
long Aeventid=Long.parseLong(muri.getLastPathSegment());
the Exception:

You are using RC-2? Please raise this on the log4j2 Jira issue tracker so it will be fixed for the upcoming 2.0 release.

I am trying the same thing and encountered a similar problem with JNDI, i created a JIRA https://issues.apache.org/jira/browse/LOG4J2-703 with my code and the stacktrace i obtained.

NumberFormatException: Invalid int: "8.0dip" only on Galaxy Tab 2

I'm currently facing to a glitch from an Galaxy Tab 10.1 2 (GT-P5110) which give me that error, but just on that device. I tried on divers emulators (I use genymotion: Nexus 5-7-10, Galaxy S3-4-5, Galaxy Note 2-3) and devices (Galaxy S -2-3-4, Nexus 5-7).
But just on that Galaxy tab 2 10.1 (GT-P5110) I have this error.
I found this link, but this didn't really help me out to solve that problem.

Apparently this would be a bug from the Samsung's Android like said here
Very frustrating >:)>:)

If you are using android:paddingstart attribute, make sure that your target api level is below 17, else try remove this attribute and run the app. It will work.
