1. 增加Intent-Filter，使得当前应用会出现在特定文件共享功能菜单里

以下示例代码表示任何类型的文件"共享"(Share via)菜单都会出现当前应用。以下intent-filter可以添加到任意activity上，也可以同时添加多个activity上

 

<intent-filter>
     <action android:name="android.intent.action.SEND" />

     <category android:name="android.intent.category.DEFAULT" />

     <data android:mimeType="*/*" />
 </intent-filter>

 

 

支持的MIME类型：

如果需要匹配特定类型，特定文件，可以用正则表达式，这里给出<data>参考链接：

2.添加相应的处理代码

 

 

@Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Intent intent = getIntent();
        Bundle extras = intent.getExtras();
        String action = intent.getAction();
        // 判断Intent是否是“分享”功能(Share Via)
        if (Intent.ACTION_SEND.equals(action))
        {
            if (extras.containsKey(Intent.EXTRA_STREAM))
            {
                try
                {
                    // 获取资源路径Uri
                    Uri uri = (Uri) extras.getParcelable(Intent.EXTRA_STREAM);
                    Log.i(TAG, "uri:" + uri.toString());
                    //解析Uri资源
                    ContentResolver cr = getContentResolver();
                    InputStream is = cr.openInputStream(uri);
                    // Get binary bytes for encode
                    byte[] data = getBytesFromFile(is);

                    return;
                }
                catch (Exception e)
                {
                    Log.e(this.getClass().getName(), e.toString());
                }

            }
            else if (extras.containsKey(Intent.EXTRA_TEXT))
            {
                return;
            }
        }
