Add `data android:scheme="file"` to home widget -

-

i have home widget follow.

<receiver android:name="org.yccheok.gui.widgetmyappwidgetprovider"     android:exported="true" >     <intent-filter >         <action android:name="android.intent.action.media_mounted" />         <data android:scheme="file"/>          <action android:name="android.appwidget.action.appwidget_update" />         <action android:name="android.appwidget.action.appwidget_enabled" />         <action android:name="android.appwidget.action.appwidget_deleted" />         <action android:name="android.appwidget.action.appwidget_disabled" />         <action android:name="android.appwidget.action.appwidget_options_changed" />     </intent-filter>      <meta-data         android:name="android.appwidget.provider"         android:resource="@xml/widget_info" /> </receiver>

i wish widget able refresh itself, when external drive available after device restarting. hence, that's why add

<data android:scheme="file"/>

however, realize that, after added <data android:scheme="file"/>, widget can no longer found in widgets list.

i encountered same issue , unable widgets appear <data> tag in appwidgetprovider's intent filter, able create new receiver handled actions separately.

in androidmanifest.xml:

<receiver android:name="org.yccheok.gui.widgetmyappwidgetprovider"     android:exported="true" >     <intent-filter >         <action android:name="android.appwidget.action.appwidget_update" />         <action android:name="android.appwidget.action.appwidget_enabled" />         <action android:name="android.appwidget.action.appwidget_deleted" />         <action android:name="android.appwidget.action.appwidget_disabled" />         <action android:name="android.appwidget.action.appwidget_options_changed" />     </intent-filter>      <meta-data         android:name="android.appwidget.provider"         android:resource="@xml/widget_info" /> </receiver>  <receiver android:name="org.yccheok.gui.myotherprovider"     android:exported="true" >     <intent-filter >         <action android:name="android.intent.action.media_mounted" />         <data android:scheme="file"/>     </intent-filter> </receiver>

in new class myotherprovider.java:

package org.yccheok.gui.myotherprovider;  import android.content.broadcastreceiver; import android.content.context; import android.content.intent;  public class myotherprovider extends broadcastreceiver {      @override     public void onreceive(context context, intent intent)     {         string action = intent.getaction();          if (intent.action_media_mounted.equals(action))         {             // want              // maybe call function in appwidgetprovider         }     } }

also, need include appwidget_update in intent filter, per http://developer.android.com/guide/topics/appwidgets/index.html#manifest

hope helps!
