Google Maps API Level 2 - Sample Code - Android Studio

Question

I am trying to run the sample Google Maps Android API v2 found on this page in Android Studio.

My question is why am I getting the android.view.InflateException: Binary XML file line #2: Error inflating class fragment shown in the logcat below?

Environment: IDE: Android Studio 1.0.1 Device: Galaxy Nexus, Android version 4.2.1

I have at looked at the related questions and tried the suggested solutions, but nothing has worked.

Most of the other question were using a FragmentActivity and needed a SupportMapFragment but I am using a regular Activity and MapFragment as shown in the example on the web page. I am using a minimum API level of 15 so I thought the FragmentActivity and SupportMapFragment were not necessary.

I have copied the example code directly from the web page.

The error from the logcat. (Only included the first bit.)

            at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2180)

The layout file activity_simple_map.xml (copied from the web page cited)

    android:name="com.google.android.gms.maps.MapFragment"/>

The Activity (copied from the web page cited)

package edu.utexas.scottm.googlemapsapi_2_demo;

import android.app.Activity;
import android.os.Bundle;


public class SimpleMapActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_simple_map);
    }
}

The manifest file (with my MAPS API key removed.)

The build.gradle file for the Module: app

apply plugin: 'com.android.application'

    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "edu.utexas.scottm.googlemapsapi_2_demo"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    compile 'com.google.android.gms:play-services:6.5.87'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
}

I have created an Android Studio project from the Google Play Services sample apps found at \android-sdk\extras\google\google_play_services\samples\maps, and it works on the device, but this uses FragmentActivity and SupportMapFragment.

Any help would be greatly appreciated.

Took a closer look at the logcat and found this:

 Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

The problem was in the manifest.

<meta-data
    android:name="com.google.android.maps.v2.MY_API_KEY"
    android:value="MY_API_KEY"/>

I put my API key at the end of com.google.android.maps.v2. instead of leaving it as

 android:name="com.google.android.maps.v2.API_KEY"

Did not read the instructions on the web page closely enough. They clearly state:

Substitute your API key for API_KEY in the value attribute.

Doh.

<?xml version="1.0" encoding="utf-8"?>
    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/iqamah_map"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:name="com.google.android.gms.maps.SupportMapFragment" />

Use FragmentActivity instead Activity

public class SimpleMapActivity extends FragmentActivity {

GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_simple_map);
        map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap();

    }
}

Sorry, I don't want to use the support library classes. My min API level is 15, so I don't need the FragmentActivity, — Mike Scott, Feb 13 '15 at 14:35

I'm not sure if i can help with the error, but this link seems to fit your needs. I used it recently for an app i created and it explains everything very well. It uses a fragment from an Activity. Hope it helps!

Thanks, but that example uses Eclipse not Android Studio. I have looked over the example code and files on that site and can't find any significant differences. – Mike Scott Feb 13 '15 at 02:43

You have three problems in the code that your logcat suggest:

First Get your API_KEY. Follow this link to get your API_KEY. Replace it in android:value="MY_API_KEY" in the manifest.xml file.

Change your java file to:

public class SimpleMapActivity extends FragmentActivity {

GoogleMap map;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_simple_map);
    map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap();
 }
}

Change your .xml file to:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/iqamah_map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.SupportMapFragment" />

Hope this Helps!!
