Failed To Find Content Provider In Api 30

UPDATE: I have to completely change my question since I found more details related to my problem. The problem: My app that resolves Content Provider doesn't work in Emulator with A

Solution 1:

The reason my custom ContentProvider doesn't work on Emulator with API 30 is Package visibility in Android 11+

To Fix my issue I've added following <queries> element into client's AndroidManifest.xml:

<manifest>
...
    <queries><packageandroid:name="com.a52.datafeeder01" /></queries>
...
</manifest>

where com.a52.datafeeder01 is the package name where custom ContentProvider is defined.

Solution 2:

In case of my problem, simply add:

<manifest>
...
    <queries><providerandroid:authorities="com.example.appcontainprovider" /></queries>
...
</manifest>

where authorities value is provider authorities.

Solution 3:

Please add the following permission in manifest

<uses-permissionandroid:name="android.permission.QUERY_ALL_PACKAGES"tools:ignore="QueryAllPackagesPermission">

This resolved my problem in android 11
