我无法在Android M上显示谷歌地图.

这是布局xml:

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

<include
    layout="@layout/toolbar_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

<LinearLayout
    android:orientation="vertical"
    android:id="@+id/content_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment
        class="com.google.android.gms.maps.SupportMapFragment"
        android:id="@+id/googleMap"
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_gravity="center"

        />
       </LinearLayout>

 </LinearLayout>

AndroidManifest文件:

<permission
    android:name="com.xxx.yyy.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.xxx.yyy.permission.MAPS_RECEIVE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

内部应用程序标签:

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="@string/maps_api_key" />

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

我在运行时请求权限:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && (checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED || checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED))
            {
                requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_COARSE_LOCATION); …
