Mapbox fails to render in XML layout View

Question

I'm using trying to use the MAPBOX sdk in my android app. I am currently using Mapbox 0.3 with android sdk 20

However, when trying to go into my layout I get the following error:

The following classes could not be instantiated:
- com.mapbox.mapboxsdk.views.MapView (Open Class, Show Exception)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when     shown in the IDE

I also have the following in my android manifest

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test.new31231" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Here is my build.gradle file:

    apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.example.test.new31231"
    minSdkVersion 15
    targetSdkVersion 20
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
repositories {
mavenCentral()
}
dependencies {
compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:0.3.0@aar'){
    transitive=true
}
compile ('com.cocoahero.android:geojson:1.0.0@aar'){
    transitive=true
}
}

any help would be greatly appreciated!

Answer 1

I i have solved it including the following line in the root element of the layout

xmlns:mapbox="http://schemas.android.com/apk/res-auto"

like in the following example

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:mapbox="http://schemas.android.com/apk/res-auto"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:background="#00000000"
              android:orientation="vertical">

              <com.mapbox.mapboxsdk.views.MapView
                        android:id="@+id/map"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        mapbox:mapid="username.xxx12345" />

</LinearLayout>
