android – 地图的棉花糖碎片活动中的崩溃

概述我正在使用fragmentActivity for maps.In Java类在setContentView上获取错误.我的Mapscreen.java就像：它在某些设备上工作正常,只显示棉花糖的崩溃.或者还有其他原因吗？ public class MapScreen extends FragmentActivity implements LocationListener,GoogleApiCl 我正在使用fragmentActivity for maps.In Java类在setContentVIEw上获取错误.我的Mapscreen.java就像：它在某些设备上工作正常,只显示棉花糖的崩溃.或者还有其他原因吗？

public class MapScreen extends FragmentActivity implements LocationListener,Googleapiclient.ConnectionCallbacks,Googleapiclient.OnConnectionFailedListener {    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.map_screen);    ....    SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()            .findFragmentByID(R.ID.map);    GoogleMap = fm.getMap();}    and my xml has fragment using SupportMapFragment as well. map_screen.xml is like :    <?xml version="1.0" enCoding="utf-8"?>    <relativeLayout       xmlns:androID="http://schemas.androID.com/apk/res/androID"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:orIEntation="vertical" >        <fragment            androID:ID="@+ID/map"            androID:name="com.Google.androID.gms.maps.SupportMapFragment"            androID:layout_wIDth="fill_parent"            androID:layout_height="fill_parent"            androID:layout_alignParentleft="true"            androID:layout_alignParenttop="true" />        <ImageVIEw            androID:ID="@+ID/startActivitybutton"            androID:layout_wIDth="wrap_content"            androID:layout_height="wrap_content"            androID:layout_alignParentBottom="true"            androID:layout_centerHorizontal="true"            androID:layout_marginleft="50dp"           androID:layout_marginRight="50dp"            androID:layout_marginBottom="44dp"           androID:background="@drawable/end_meetup_btn"         />    </relativeLayout>

我无法找到相同的问题在Marshmallow中遇到崩溃：“二进制XML文件行#7：错误膨胀类片段”请建议！
试图找到“引起：java.lang.NullPointerException：尝试在空对象引用上调用虚方法’boolean java.io.file.mkdir()’”.

解决方法 问题出在“Micro-max AndroID one mobile”,这是6.0 Marshmallow.
此设备没有足够的内部或外部存储空间.即使没有SD卡.

在听完George的回答之后：

NullPointerException from Google maps

我安装了存储卡,现在崩溃不来了.

所以我发现问题是更新了Google Play服务,这些服务需要我的设备中不够的Space(更新后的Google照片).

并且还有一个错误行显示“由以下引起：java.lang.NullPointerException：尝试在空对象引用上调用虚方法’boolean java.io.file.mkdir()’”

我决定在安装SD卡后检查.它奏效了
