What kind of permission are you using ?

If your application isn't signatureOrSystem, you can only access your own channels and programs from queries to the TV provider. All the queries you're doing are filtered on your package name.

Additionally to "com.android.providers.tv.xxx" EPG permissions needed in the manifest file, you must sign your .apk ! Otherwise you will see all the TvInput available on your device but none of the channels composing these tvInput (and this, without any error returned ;-)). Android Studio provides this features ('BUILD' menu entry then 'Generate Signed APK') see How to sign an android apk file
