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!
github repo for a project that reproduces the crash

Here is my xml layout for passanger fragment
<fragment
android:id="#+id/mapPassenger"
class="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/fragment_map" />
I am totally new to fragments.. i have also search alot for this but
m unable to solve my problem please help me on this thanks

Are you trying to inflate a fragment... inside a fragment_layout?
Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.
Please see this post.

Simple answer!
you check if view is already created in fragment then return else add like this
GoogleMap fragmentMap;
if(fragmentMap==null)
fragmentMap = ((com.google.android.gms.maps.MapFragment) getActivity().getFragmentManager().
findFragmentById(R.id.mapfragment)).getMap();

I also changed gradle from 9 to 12
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
}
How to solve this problem?
thank you!
I do not know exactly what I did, but it works !
I cleaned the project (build-clear project) and I changed something in build.grandle
apply plugin: 'android'
android {
compileSdkVersion 19
buildToolsVersion '19.1.0'
defaultConfig {
minSdkVersion 10
targetSdkVersion 14
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:+'
compile project(':libraries:facebook')
compile 'com.google.android.gms:play-services:4.2.42'
compile 'com.android.support:appcompat-v7:+'
}

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.
