Change Android app title but not homescreen name [duplicate]

Question

The name of my app is "[T]ime [T]racking [M]anager". Since that's too long at the homescreen (only "[T]ime [T]r..." is shown) I want my apps name to be "TTM" on the homescreen and app selection but I want the title of the app to be the full name. Like this:

I tried to change my AndroidManifest like this:

 <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="TTM" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity" android:label="[T]ime [T]racking [M]anager"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application>

But now the name is everywhere (on homescreen AND title of the app) "[T]ime [T]racking [M]anager". How can I name them differently?

u want the app name on menu screen of phone as TTM but on HomeScreen u want as full form? right? — Prajwal Waingankar

You have to set the Activity title programmatically like below:

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); getSupportActionBar().setTitle("[T]ime [T]racking [M]anager"); } }

And remove android:label from activity tag

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