share data between app by content provider is not work

Question

I create First App and his name "provides" and I use SQLite Database for create table and insert data to a table and everything is work. and I create Second App and his name "consumes" his app is responsible to receive data from my first app then I create Content Provider in the first app and this is code :

class Provider : ContentProvider() {
    private lateinit var db: LoginSqliteHelper
    override fun onCreate(): Boolean {
        db = LoginSqliteHelper(context!!)
        return true
    }

    override fun query(
        uri: Uri,
        projection: Array<out String>?,
        selection: String?,
        selectionArgs: Array<out String>?,
        sortOrder: String?
    ): Cursor? {
        return db.readableDatabase.query(
            ConstantValue.Table_Name,
            projection,
            selection,
            selectionArgs,
            null,
            null,
            sortOrder
        )
    }

    override fun getType(uri: Uri): String? {
        return "vnd.android.cursor.dir/vnd.example.storge.provider"
    }

    override fun insert(uri: Uri, values: ContentValues?): Uri? {
        TODO("Not yet implemented")
    }

    override fun delete(uri: Uri, selection: String?, selectionArgs: Array<out String>?): Int {
        TODO("Not yet implemented")
    }

    override fun update(
        uri: Uri,
        values: ContentValues?,
        selection: String?,
        selectionArgs: Array<out String>?
    ): Int {
        TODO("Not yet implemented")
    }
}

then I Create Provider in the manifest

<provider
            android:name=".sqlite.Provider"
            android:authorities="com.example.storage"
            android:enabled="true"
            android:exported="true" />

for information the package name to first app is "com.example.storage" then I receive data from my first app in the second app by this method :

val uri = Uri.parse("content://com.example.storge")
        val cursor = contentResolver.query(uri, null, null, null, null)
        if (cursor != null){
            while (cursor.moveToNext()) {
                for (i in 0 until cursor.columnCount) {
                    Log.d(TAG, "$i - ${cursor.getColumnName(i)} ${cursor.getString(i)}")
                }
            }
            cursor.close()
        }

but the cursor is null , I do not know why null !?

The first application works effectively, but when I run the second application, it does not receive any data from the first application. What is the reason?
