I am having issues inflating a Mapbox MapView on an Android Fragment. When I use the same code on an Activity (other than standard differences between an Activity and a Fragment), I can get the MapView to load correctly, but not on the Fragment.
Mapbox also has a MapFragment class here, but I am unsure how to use this properly in a Fragment (the example is still in an Activity); with the Google Maps API I am able to use a MapView on a Fragment without a problem.
The below logcat line of:
at com.example.exampleapp.FragmentMap.onCreateView(FragmentMap.java:133)
is referring to the Java line:
fragmentLayout = inflater.inflate(R.layout.fragment_map, container, false);
Here is the relevant code for this issue along with the log:
fragment_map.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mapbox="http://schemas.android.com/apk/res-auto"

You are telling about inflation but look at stack trace:
Caused by: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.exampleapp-2/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]] couldn't find "libmapbox-gl.so" at java.lang.Runtime.loadLibrary(Runtime.java:366) at java.lang.System.loadLibrary(System.java:988) at com.mapbox.mapboxsdk.views.NativeMapView.(NativeMapView.java:42) at com.mapbox.mapboxsdk.views.MapView.initialize(MapView.java:680) at com.mapbox.mapboxsdk.views.MapView.(MapView.java:621)
BTW:
first
u need to decide if u inflate view every time {local variable) or u reuse it (global one)
example:
if(_view==null)
_view = inflater.inflate(..);
return _view;
second:
do not call activities or fragment methods like onCreate onPause manually (those used by os to maintain life cycle)
third:
if u use viewpager and nested fragments u need create adapter with child fragment manager
more & more:
keep in mind that to set some data and properties in child fragment viewpager fragment need to laid out
"First: I am inflating it every time, which is usually not a problem (my tabs work with any other fragment I have created, including Google Maps, just not Mapbox) Second: Yes, you do call activity lifecycle methods manually. You have to use onCreate to inflate a view. Third: I have an adapter, I just did not include it here. That is not the issue, my tabs work fine with any other fragment I have created. Lastly: I'm not sure what you're saying, but my fragments work fine in my other tabs.
Please focus on the problem at hand... putting a Mapbox view in a fragment, > regardless of where that fragment is (tab pageviewer or not).. – TangoJLabs"

move this from onCreate of fragment to onViewCreated(View,Bundle)

last word: gradle files
i dont know if your file content contains both gradle files or only app file but those lines shouldnt be in app gradle file - those are top level gradle :
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
}
}
repositories {
mavenCentral()
jcenter()
}
and u should consider to move to newest android app plugin - but i see you are using gms services - so u top gradle file is containing other plugin and those above is omitted
I'm having trouble following the logic of your edits. I don't have an onCreate from which I can move anything
/** inflate fragment - this will create view */
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_map, container, false);
}
/** after view is created - set map view */
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
if(view!=null) {
MapView mv = (MapView) view.findViewById(R.id.mapview);
mv.onCreate(savedInstanceState);
}
}
btw i have more concerns on rest of lifecycle methods - fragment could or not retain state so simple putting activity lifecycle methods in fragment method could produce more problems :)
i don't use & know the source implementation of MapView so i cant tell u how to implement this but i can give u a hint to check if fragment is attached to activity before u call any mapview method
@ceph3us -1 everything mentioned in this is wrong, and your grammar can be improved. I don't have an answer to this, I am here with the same question. 1st root view should not be a field, it should be inflated on each call to onCreateView, 2nd those are proper calls, 3rd and the rest are off topic and not helpful to the subject. – HaydenKai
