棉花糖系统中地图片段活动闪退问题

androidgoogle-mapsandroid-fragmentactivity

我正在使用FragmentActivity来加载地图。在Java类中，执行setContentView时出错。我的Mapsreen.java代码如下: 在一些设备上运行良好，在Marshmallow上会崩溃。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>

我找不到同样的问题。在Marshmallow中出现崩溃：“二进制XML文件第7行：充气类片段错误”。请给出建议！尝试查找“Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.io.File.mkdir()' on a null object reference”。

问题出在“Micro-max Android one mobile”上，这是一个6.0 Marshmallow系统的设备。该设备没有足够的内部或外部存储空间，甚至没有SD卡。根据George在以下链接中的回答：NullPointerException from Google maps，我安装了存储卡，现在不再崩溃了。所以我发现问题是更新的Google Play服务需要空间（更新的Google照片），而我的设备空间不足。另外，一个错误行显示为“Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.io.File.mkdir()' on a null object reference”。我决定在安装SD卡后进行检查。结果它成功了。
多么大的一个错误啊！ - Piyush
是的，你说得对。我在Micromax AQ4509上也遇到了同样的问题。 - Amol Suryawanshi
我想捕获这个错误并向最终用户显示一条消息，提示插入SD卡。 - Vinil Chandran

<!-- EXTERNAL_STORAGE permissions are optional for Android 6.0 onwards. -->
    <uses-permission
        android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        android:maxSdkVersion="22" />
    <uses-permission
        android:name="android.permission.READ_EXTERNAL_STORAGE"
        android:maxSdkVersion="22" />

将此内容添加到您的清单中。也许地图需要SD卡权限进行一些额外的缓存或其他操作。

问题已在Google Play服务库的9.0.83版本中得到修复。

在您的清单文件中添加SD卡权限。
    <uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
     />

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

这只是我做的一个变通方法。如果下面的检查失败，我会加载一个带有错误的片段，而不是加载地图。

/** Checks if external storage is available for read and write */
public boolean isExternalStorageWritable() {
    String state = Environment.getExternalStorageState();
    return Environment.MEDIA_MOUNTED.equals(state);
}
