@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_quick_launch);
    }

/** Called when the user clicks the  music button */
     public void music(View view) {
         Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");
         intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
         startActivity(intent);

}

public void play(View view) {
    Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.android.vending");
    startActivity(launchIntent);
    }

/** Called when the user clicks the web button */

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="22" />

<application
        android:allowBackup="true"

        <activity
            android:name="com.d4a.toolbelt.QuickLaunch" android:launchMode="singleInstance" android:theme="@style/Theme.Transparent">
                      <intent-filter>
                <action android:name="android.intent.action.ASSIST" />
                <action android:name="android.intent.extra.ASSIST_CONTEXT" />
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

Any help would be great

Thanks in advance!

When you press and hold the Home button in your Marshmallow device, it invokes the default assistive app set in Settings> Apps> Configure App (the settings icon on the toolbar), >Default Apps> Assistive & Speech Input, > Assistive Apps.

You can check if your app is set as the default Assist app,

and you can redirect the user to the settings screen in your activity with the following code, where the user can select the default Assist app.

        String assistant =
                Settings.Secure.getString(getContentResolver(),
                        "voice_interaction_service");

boolean areWeGood = false;

if (assistant != null) {
            ComponentName cn = ComponentName.unflattenFromString(assistant);

if (cn.getPackageName().equals(getPackageName())) {
                areWeGood = true;
            }
        }

if (areWeGood) {
            your app has already been set as Assist app.
            finish();
        } else {
             your app has not been set as Assist app. Redirect user to the settings screen. 
            startActivity(new Intent(Settings.ACTION_VOICE_INPUT_SETTINGS));
        }
