在Android中注册新文件类型 [英] Register a new file type in Android

问题描述

我想在Android上编写一个简单的STL(几何数据文件)查看器应用程序，但无法识别系统的格式.我在应用清单文件中写了这个:

I want to write a simple STL (geometrical data file) viewer application on Android, but I'm not able to make recognize a format to the system. I wrote this in my app manifest file:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <action android:name="android.intent.action.EDIT" />
    <action android:name="android.intent.action.PICK" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:scheme="http" />
    <data android:pathPattern=".*\\.stl" />
    <data android:mimeType="application/sla" />
    <data android:host="*" />
</intent-filter>

但是当我启动浏览器并下载一些示例STL文件时，下载被中断，并且我报告系统的数据文件类型未知.

But the moment I launch the browser and go to download some sample STL file, the download is interrupted and I'm reported that the data file type is unknown for the system.

我没有真正的Android设备，所以我只使用一个仿真器，并且为了开发我在MonoDroid上使用C#(但老实说我不认为这是问题所在).

I have no real Android device, so I use only an emulator, and for development I use C# on MonoDroid (but I honestly don't think that is the problem).

我该如何解决此问题?

推荐答案

我正在使用此清单在我的应用程序中注册(例如).stl文件类型:

I'm using this manifest to register (for example) a .stl file type with my application:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.test.core" android:versionCode="1" android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Testy" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name="ThorActivity" android:label="@string/app_name">
        </activity>

        <activity android:name="LokiActivity" android:label="@string/app_name">
        </activity>

        <activity android:name="OdinActivity" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="http" android:host="*"
                    android:pathPattern=".*\\.stl" />
                <data android:scheme="https" android:host="*"
                    android:pathPattern=".*\\.stl" />
                <data android:scheme="content" android:host="*"
                    android:pathPattern=".*\\.stl" />
                <data android:scheme="file" android:host="*"
                    android:pathPattern=".*\\.stl" />
            </intent-filter>
        </activity>
    </application>

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

</manifest>

如您所见，我将.stl文件扩展名链接到活动OdinActivity.在OdinActivity内，我使用以下行获取文件路径，以便可以打开它:

As you can see, I'm linking the .stl file extension to the activity OdinActivity. Inside the OdinActivity, I use the following line to get the file path so I can open it:

filePath = getIntent().getData().getEncodedPath();

然后我将其打开以进行阅读:

Then I just open it to read from it:

FileOutputStream out = new FileOutputStream(new File(filePath));
