The user can elect to do this by checking the "make this the default" checkbox at the bottom of the chooser dialog.

You, as a developer, cannot unilaterally make yourself the default.

My activity reads a tags NFC but how android have already installed other NFC app with the same intent filter i dont know any solution.

Your filter says that you want to handle all tags. If that is true, then the user will have to choose whether to make your app the default.

However, you can make a tighter filter and take priority. For example:

<activity android:name="URLHandler" android:label="@string/app_name">
    <intent-filter android:label="@string/app_name">
        <action android:name="android.nfc.action.NDEF_DISCOVERED" />
        <data android:scheme="http"
                    android:host="commonsware.com"
                    android:path="/nfctest"
        />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

Here, my activity will get control if (and only if) the tag has an NDEF record that results in a URL of http://commonsware.com/nfctest. Since my filter has tighter scope than other competing applications, mine will get control without a chooser.
