Question

Three months and I still can't get a working Google Map on my project.

I tried a lot of tutorial's but always the same problem I can't run it and I don't know how to fix it.

This my Manifest.xml

<?xml version="1.0" encoding="utf-8"?>

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

        //geolocalisation

Answer 1

You are really close, it looks like you just added the <meta-data> tags in the wrong location under <activity> rather than <application>

Try using this code for you manifest instead:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidmaphmida"
    android:versionCode="1"
    android:versionName="1.0" >

<permission
    android:name="com.example.androidmaphmida.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.example.androidmaphmida.permission.MAPS_RECEIVE" />

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="21" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<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" />


<!-- Required OpenGL ES 2.0. for Maps V2 -->
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name">
    <activity
        android:name="com.example.androidmaphmida.MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppBaseTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

  <!-- Goolge API Key -->
  <meta-data
      android:name="com.google.android.maps.v2.API_KEY"
      android:value="AIzaSyBg-SzhfkXjGUDK037BbmsG4Hv3yrY6c2M" />
  <meta-data
      android:name="android.support.PARENT_ACTIVITY"
      android:value="com.example.androidmaphmida.MainActivity" />
  <meta-data
      android:name="com.google.android.gms.version"
      android:value="@integer/google_play_services_version" />

</application>

Answer 2

尝试以这种方式替换您的Java文件和布局文件：

activity_main.xml中

splitUsers(36) into( 
    atOnceIncrementalUsers(1)) 
    separatedBy(30 seconds))

MainActivity.java：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/hello_world" />
    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"/>

</RelativeLayout>
