Hi,
i am trying to load an html file which refers an image stored in the
sdcard. Actualy the html is provided by a local servlet. in the html,
i have this line "<img id="toto" src="file:///sdcard/path/path/
toto.png"/><br>".
When i used that, i had this error : " Not allowed to load local
resource: file://".
I find out that android does not allow this kind of things for
security reasons . So i searched on Internet(see links at the ends)
and i saw that i need to create my own ContentProvider to handle the
way to access the local files. I did it by creating a
LocalContentProvider that extends ContentProvider and i overwrited the
method openFile(android.net.Uri uri, java.lang.String mode). Then i
modified the androidManifest to add the provider.
androidManifest:
<provider android:name="LocalContentProvider"
android:authorities="com.myCompany.myPackageName" />
LocalContentProvider (stored in com.myCompany.myPackageName):
public ParcelFileDescriptor openFile(Uri uri, String mode) throws
FileNotFoundException {
URI fileURI = URI.create( "file://" + uri.getPath() );
File file = new File( fileURI );
ParcelFileDescriptor parcel=null;
try {
parcel = ParcelFileDescriptor.open(file,
ParcelFileDescriptor.MODE_READ_ONLY);
} catch (FileNotFoundException e) {
Log.d(LOG_TAG,"Error finding: " + fileURI + "\n" +
e.toString());
}
return parcel;
}
After theses modifications i tryed with <img id="toto" src="content://
com.myCompany.myPackageName/sdcard/path/path/toto.png"/><br> and i
had
"Failed to find provider info for com.myCompany.myPackageName"
here is my question:
How can i change the html to make it access the local files via the
contentProvider ?
What am i doing wrong ?
i' based on theses exemples:

i' am using Android 1.6 SDK, Release 1 on windows XP.
Thank you for your help and i am sorry for my very bad english.
Yaya.
