        <intent-filter>             <action android:name="com.my.testimportapp.launch" />             <action android:name="android.intent.action.send" />             <action android:name="android.intent.action.view" />             <action android:name="android.intent.action.edit" />             <action android:name="android.intent.action.paste" />             <action android:name="android.intent.action.open_document" />             <action android:name="android.intent.action.get_content" />             <action android:name="android.intent.action.insert" />             <action android:name="android.intent.action.insert_or_edit" />             <action android:name="android.intent.action.sendto" />             <action android:name="android.intent.action.send_multiple" />             <action android:name="android.intent.action.pick" />             <category android:name="android.intent.category.category_browsable" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.launcher" />             <data android:scheme="http" />             <data android:scheme="https" />             <data android:scheme="ftp" />             <data android:scheme="file" />             <data android:scheme="data" />             <data android:scheme="info" />             <data android:scheme="data" />             <data android:scheme="smb" />             <data android:scheme="nfs" />             <data android:scheme="android.resource" />             <data android:mimetype="text/comma-separated-values"/>             <data android:mimetype="text/csv"/>             <data android:mimetype="text/plain"/>         </intent-filter>

        <intent-filter>             <action android:name="android.intent.action.send" />             <action android:name="android.intent.action.send_multiple" />             <action android:name="android.intent.action.view" />             <action android:name="android.intent.action.open_document" />             <action android:name="android.intent.action.pick" />             <category android:name="android.intent.category.browsable" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.launcher" />             <category android:name="android.intent.category.alternative" />             <data android:scheme="http" />             <data android:scheme="https" />             <data android:scheme="ftp" />             <data android:scheme="file" />             <data android:scheme="data" />             <data android:scheme="info" />             <data android:scheme="data" />             <data android:scheme="smb" />             <data android:scheme="nfs" />             <data android:mimetype="text/comma-separated-values"/>             <data android:mimetype="text/csv"/>             <data android:mimetype="text/plain"/>         </intent-filter>         <intent-filter>             <action android:name="android.intent.action.send" />             <action android:name="android.intent.action.send_multiple" />             <action android:name="android.intent.action.view" />             <action android:name="android.intent.action.open_document" />             <action android:name="android.intent.action.pick" />             <category android:name="android.intent.category.browsable" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.launcher" />             <category android:name="android.intent.category.alternative" />             <data android:scheme="http" />             <data android:scheme="https" />             <data android:scheme="ftp" />             <data android:scheme="file" />             <data android:scheme="data" />             <data android:scheme="info" />             <data android:scheme="data" />             <data android:scheme="smb" />             <data android:scheme="nfs" />             <data android:host="*" />             <data android:pathpattern="/.*\\.csv" />             <data android:pathpattern="/.*\\.csv" />             <data android:pathpattern="/.*\\.txt" />             <data android:pathpattern="/.*\\.text" />         </intent-filter>         <intent-filter>             <action android:name="android.intent.action.send" />             <action android:name="android.intent.action.send_multiple" />             <action android:name="android.intent.action.view" />             <action android:name="android.intent.action.open_document" />             <action android:name="android.intent.action.pick" />             <category android:name="android.intent.category.browsable" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.launcher" />             <category android:name="android.intent.category.alternative" />             <data android:mimetype="text/comma-separated-values"/>             <data android:mimetype="text/csv"/>             <data android:mimetype="text/plain"/>         </intent-filter>
