android – 地图的棉花糖碎片活动中的崩溃

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
