Answer 1

I was using onNewIntent for search implementation in Android. I came across the problem that onNewIntent wasn't being called when I used the Go button on the keyboard in the emulator. I solved the issue by placing my code for handling the intent in the onCreate method also. This needs to be done to make sure that the intent action is handled when a fresh instance of the activity is started.

This posed a problem as onCreate is called whenever the activity is restored from a previous state too. So, the intent handling method gets called even when an orientation change occurs.

Solution : Use if (savedInstanceState==null) to determine if activity is being restored from a previous state, or is it a fresh search.

Answer 2

The best way to handle onNewIntent with singleTop is simply this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent);
}

Then do all of your logic on getIntent inside onResume.

Answer 3

for me I didn't add search action to the activity in the manifest:

<activity android:name=".SearchResultsActivity" ... >
    ...
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
    </intent-filter>
    ...
</activity>

Answer 4

Here's one situation that might bite you, along with a bit more information: onNewIntent is called as expected with this code:

Intent intent = new Intent...
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
finish();
startActivity(intent);

but not with this code

Intent intent = new Intent...
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intent);
finish();

The reason for that is that, in the second code block, the new activity is added on top before calling finish for the current activity, so to get the second code block to work you must add the FLAG_ACTIVITY_CLEAR_TOP flag as suggested by some of the other answers, like this:

Intent intent = new Intent...
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

Note that finish is not called at all here, because it is called for you. From the documentation for the FLAG_ACTIVITY_CLEAR_TOP flag:

If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

Answer 5

The Activity you want to receive onNewIntent() in should have

android:launchMode="singleTop"

Or add the flag tn intent

browserInt.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                    Intent.FLAG_ACTIVITY_SINGLE_TOP);

As documented in onNewIntent(Intent)

Answer 6

To enter to the onNewIntent method, you need in your AndroidManifest.xml file, put after set you main activity a launch mode, in this launch mode you have to put singleInstance e.g:

<activity 
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:launchMode="singleInstance"
        android:windowSoftInputMode="adjustPan" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

Now you will able to enter to you onNewIntent method.
