android9.0将自己的应用加入系统的打开方式和分享列表中

前言

继Android7.0版本后 Uri和文件路径互相转换封装类，实现系统分享功能及 FileProvider详细解析和踩坑指南，与fileprovider生成的Uri无法被识别 后，再谈android如何将自己的应用加入系统的打开方式和分享列表中。

 

1、分享列表中显示自己的应用

①在用系统默认的分享功能都会调用系统中可分享的应用的一个列表，但是如何使自己的应用加入这个列表呢？首先需要配置androidmanifest.xml,在分享页面的activity加入下边的Intent过滤器
 

<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="*/*" />
</intent-filter>

这样就可以第三方应用分享过滤分享的时候自己的应用出现在列表中。
②接受内容，在对应的activity中intent中获取相关的数据

title = intent.getStringExtra(SHARE_IMG_TITLE);
(Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM)

Intent intent = getIntent();
        String action = intent.getAction();
        if (Intent.ACTION_SEND.equals(action)) {
            Uri uri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
//            Uri uri = intent.getData();
            String filename = uri.getPath();
            if (String.valueOf(uri) != null
                    && String.valueOf(uri).contains("content")) {
                boolean kkk = false;
                try{
                    filename = CommonUtils.getFilePathFromContentUri(uri,this.getContentResolver());
                    if(CommonUtils.isEmpty(filename)){
                        kkk = true;
                    }
                }catch (Exception e){
                    e.printStackTrace();
                    kkk = true;
                }
                if(kkk){
                    filename = ProviderUtils.getFPUriToPath(this,uri);
                }
            }

备注：CommonUtils.getFilePathFromContentUri（）和ProviderUtils.getFPUriToPath（）方法见Android7.0版本后 Uri和文件路径互相转换封装类，实现系统分享功能及 FileProvider详细解析和踩坑指南，与fileprovider生成的Uri无法被识别 ，此处不再赘述。

具体的mimeType类型有
{".3gp", "video/3gpp"},
{".apk", "application/vnd.android.package-archive"},
{".asf", "video/x-ms-asf"},

{".h", "text/plain"},
{".htm", "text/html"},

{".zip", "application/zip"},
{"", "/"}

2、打开方式中增加自己的应用

①安卓中的文件打开一般都会让选择打开方式即第三方应用打开，如微信中打开文件选择第三方应用打开，其实也算是一种分享，具体方法和分享类似只是filter名字是view

<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>

②在activity中

Intent intent = getIntent();
String action = intent.getAction();
if (Intent.ACTION_VIEW.equals(action)) {
            Uri uri = intent.getData();
            String filename = uri.getPath();
            if (String.valueOf(uri) != null
                    && String.valueOf(uri).contains("content")) {
                boolean kkk = false;
                try{
                    filename = CommonUtils.getFilePathFromContentUri(uri,this.getContentResolver());
                    if(CommonUtils.isEmpty(filename)){
                        kkk = true;
                    }
                }catch (Exception e){
                    e.printStackTrace();
                    kkk = true;
                }
                if(kkk){
                    filename = ProviderUtils.getFPUriToPath(this,uri);
                }
            }
