Declaring CrimeListActivity in AndroidManifest.xml

Android Programming (3rd Edition) 8. Displaying Lists with RecyclerView
1

I can’t find any solution for AndroidManifest.xml that to changed tags .CrimeActivity to CrimesListActivity…

in CrimeActivity, createFragment() method is called to CrimeFragment() but in CrimeListActivity, createFragment() method is called CrimeListFragment.
And I know the beginTransaction() method gets resource fragment_container id in SingleFragmentAcitivity.
So finally I changed AndroidManifest.xml and run to an emulator.However, Emulator doesn’t start/launch with crimeListActivity that according to the book, it is a blank page.

  <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".CrimeListActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity android:name=".CrimeActivity">

    </activity>
</application>

Can you help me, please?
Thanks a lot.

This is a good book, but Chap 8 needs improvement. For one, as a prep to it, there should be a Challenge at the end of Chap 7 to clarify Fragments. There is a lot presented in Chap 8, and to help digest it, it would be nice to clarify there is code from Chap 7 that Chap 8 doesn’t use. It is confusing to keep CrimeActivity in the Manifest, for example. … it is not used (nor is CrimeFragment) - it can be put back into the Manifest when needed. So, if the text is not changed to make these “improvements” (and I realize that’s a big thing to do), at least provide another Challenge at the end of Chap 8 that states: “Some of the code developed so far is not necessary to run the emulator and achieve FIgure 8.10. What code can you delete and have it still run (hint: also look at the Manifest file and see if there’s something that can be deleted)”. A final comment is that it would be nice to put into Fig 8.2 the SingleFragmentActivity - that is an essential part of the MCV architecture for Chap 8.

I’m with the same problem. And I can’t seem to find a solution. It seems you were able to find it but the link you provided is broken. Would you or anyone be kind to share the solution with the rest of the group with a link that isn’t broken.

Thank you.

PS: I am using the 3rd edition.
