地图的 Marshmallow Fragment Activity 崩溃

Question

我正在为 maps.In Java class 使用 fragmentActivity 在 setContentView 上出现错误。我的 Mapscreen.java 是这样的：它在某些设备上工作正常，但在 marshmallow 上显示崩溃 only.Or 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>

我找不到相同的问题在 Marshmallow 中崩溃："Binary XML file line #7: Error inflating class fragment" 请提出建议！ 也试图找到 "Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.io.File.mkdir()' on a null object reference"。

Answer 1

问题发生在 "Micro-max Android one mobile"，即 6.0 Marshmallow。此设备没有足够的内部或外部内存space.Even 没有 SD 卡。

按照 George 的回答后：

我安装了内存卡，现在不会崩溃了。

所以我发现问题已更新 Google 需要 Space 的播放服务（更新 Google 照片）在我的设备中是不够的。

并且错误行之一显示 "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。它奏效了

Answer 2

<!-- 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" />

将此添加到您的清单中。也许地图需要 sdcard 权限才能进行一些额外的缓存或其他操作。

Answer 3

这只是我所做的解决方法。如果下面的检查失败，我没有加载地图，而是加载了一个错误的片段。

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

Answer 4

将 SD 卡权限添加到您的清单文件。

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

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