Issue
We are attempting to hook up our AndroidTV app to append results into the global search. I'm running into an issue where I cannot make an api call to get the results because the system calls my content provider on the main thread.
@Override
public Cursor query(Uri uri, String[] projection, String search, String[] selectionArgs, String searchOrder) {
... Logic here that calls the API using RxJava / Retrofit
return cursor;
}
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/foo"
android:searchSettingsDescription="@string/foo_results"
android:includeInGlobalSearch="true"
android:searchSuggestAuthority="com.foo.search.provider"
android:searchSuggestIntentAction="android.intent.action.VIEW" />
<provider
android:authorities="com.foo.search.provider"
android:name=".search.GlobalSearchProvider"
android:exported="true"/>
When i do a global search i can see that the ContentProvider#query is called. If i attempt to do an api call on the current thread i get an networkonmainthreadexception.
I have attempted to notifty the cursor that data has changed via but had no success either.
getContext().getContentResolver().notifyChange(Uri.parse("content://com.foo.test"), null);
...
cursor.setNotificationUri(getContext().getContentResolver(), Uri.parse("content://com.foo.test"));
Is there anyway i can force the O.S to call the content provider on a seperate thread or at least notify the search that the cursor has new content?
Thank You
Solution
One of the solutions can be to set the content provider process
android:process:":androidtv"
and set the ThreadPolicy to LAX just before making network call
ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);
By running contentprovider in a different process, even if the query runs on main thread, it will not affect your UI operations
