Following the notepad example in the SDK i have created my
ContentProvider class, my BaseColumns class and added the provider to
the manifest file.
Manifest:
<provider android:name="com.smithmyers.providers.MGProvider"
android:authorities="com.smithmyers.providers.MGScans"
/>
Provider and BaseColumns classes are almost identical to the NotePad
example though using my content URI and a slightly different table in
my database.
in onCreate in my activity i have the following code:
Intent intent = getIntent();
if (intent.getData() == null) {
intent.setData(Scans.CONTENT_URI);
}
getContentResolver().insert(intent.getData(), null);
>From this code i get this error:
Uncaught handler: thread main exiting due to uncaught exception
