Question

EXTRA_APPLICATION_ID seems not to work in the tablet. Do you know other work around to reuse tab of the Browser.apk when starting the Browser by intent from my service. This is directly related to 9902225. Any hints is appreciated.

Cause: The resuseTab() will not be called if the device is a tablet.

See line:

* 3-tablet) Open new tab

See line:

if (activateVoiceSearch || !BrowserActivity.isTablet(mActivity)) {

// Browser.apk source code (Android 4.0.3_r1-6)

com.android.browser.IntentHandler

void onNewIntent(Intent intent) {
....
   /*
     * TODO: Don't allow javascript URIs
     * 0) If this is a javascript: URI, *always* open a new tab
     * 1) If this is a voice search, re-use tab for appId
     *    If there is no appId, use current tab
     * 2) If the URL is already opened, switch to that tab
     * 3-phone) Reuse tab with same appId
     * 3-tablet) Open new tab

    final String appId = intent
            .getStringExtra(Browser.EXTRA_APPLICATION_ID);
    if (!TextUtils.isEmpty(urlData.mUrl) &&

        // Always open javascript: URIs in new tabs
        mController.openTab(urlData);
        return;

    if ((Intent.ACTION_VIEW.equals(action)

            // will be opened in a new tab unless we have reached

For ICS and tablet devices, you need to set the intent’s App ID as the browser’s App ID.
So you need to use com.android.browser instead of getPackageName()
