• android 调用微信QQ的其他应用打开列表中添加自己的应用,并且获取uri brave


    清单文件配置指定的activity配置如下:

    复制代码
     <!--调用微信的其他应用打开列表添加自己应用  -->
                <intent-filter>
                    <action android:name="android.intent.action.VIEW" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <data android:scheme="content"/>
                    <!-- 允许所有类型文件-->
                    <data android:mimeType="*/*" />
                    <!-- 只允许图片文件-->
                    <!--<data android:mimeType="image/*"/>-->
                </intent-filter>
                <!--调用QQ的其他应用打开列表添加自己应用  -->
                <intent-filter>
                    <action android:name="android.intent.action.VIEW" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <data android:scheme="file"/>
                    <!-- 允许所有类型文件-->
                    <data android:mimeType="*/*" />
                    <!-- 只允许图片文件-->
                    <!--<data android:mimeType="image/*"/>-->
                </intent-filter>

    获取uri

     //获取uri
                Intent intent = getIntent();
                Uri  uri = intent.getData();
                String  url = intent.getDataString();
                Log.e("url", url);

    将uri转为文件路径
