No Activity found to handle Intent action.VIEW when clicking email link

Question

I got this new crash exception after the newest app update. It seems to not point anywhere. Would anyone be able to tell what the issue is? It looks like a possible email-formatting issue due to this: dat=mailto:[email protected] (has extras) ....but I am not sure I have any errors in emails.

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW
dat=mailto:[email protected] (has extras) }

Could something like this be a problem:

<TextView
    android:id="@+id/contact_email"    
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop ="15dp" 
    android:autoLink="email"
    android:text="[email protected]"

    />

Answer 1

I ran into this problem as well, the thing is that when you define:

android:autoLink="email"
android:text="[email protected]"

or any other type of autolink in a TextView, android handles everything for you.

In the emulator email is not setup by default, so there is no app to handle the intent, and this makes your app crash if you click an autolinked email address. If you open the mail app and follow the instructions to set it up, then when you click the email address it will work.

I don't know what you can do to work around this issue. I guess it might not be safe to assume the user has mail setup or at least one app capable of handling that intent. I also guess that the app shouldn't be crashing... I think this is an issue with android as in this case you have no way of handling the exception.

If you look at the source of URLSpan (If autolink is set, TextView uses android.text.util.Linkify.addLinks(..) which creates instances of URLSpan to create links): http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.1.2_r1/android/text/style/URLSpan.java#URLSpan

public void onClick(View widget) {
    Uri uri = Uri.parse(getURL());
    Context context = widget.getContext();
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    intent.putExtra(Browser.EXTRA_APPLICATION_ID, context.getPackageName());
    context.startActivity(intent);
}

They could either handle the exception or use PackageManager to determine if the Intent would succeed before calling startActivity() (like they recommend: http://developer.android.com/training/basics/intents/sending.html#Verify) or use a chooser.

Although the Android platform guarantees that certain intents will resolve to one of the built-in apps (such as the Phone, Email, or Calendar app), you should always include a verification step before invoking an intent.

Caution: If you invoke an intent and there is no app available on the device that can handle the intent, your app will crash.

So my question would be: is there any guarantee that an email intent will always resolve on a real device?

ok... on the same section they also mention:

Note: You should perform this check when your activity first starts in case you need to disable the feature that uses the intent before the user attempts to use it. If you know of a specific app that can handle the intent, you can also provide a link for the user to download the app (see how to link to your product on Google Play).

One can always check if the intent resolves to any activity at the start of the application, set a flag and every time the layout containing such TextView is inflated we find it and disable auto link for email, etc. (and this is when I ponder killing an unicorn over coding that)

Answer 2

By the way no email client can occur if no email account is set up on the device so technically this can occur on real devices as well. Here is the code for disabling the AutoLink if not available as suggested by novettam:

protected boolean checkIntent(Intent intent)
{
    PackageManager packageManager = getPackageManager();
    List<ResolveInfo> apps = packageManager.queryIntentActivities(intent, 0);
    return apps.size() > 0 && !( apps.get(0).activityInfo.name.equals(activity.getClass().getName()) && apps.size() == 1) ;
}


protected Intent createDummyEmailIntent()
{
    final Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
            "mailto", "[email protected]", null));
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "EXTRA_SUBJECT");
    return emailIntent;
}

protected Intent createDummyWebIntent()
{
    final Intent webIntent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://www.google.co.uk"));
    return webIntent;
}

protected Intent createDummyPhoneIntent(){
    String uri = "tel:" + "0131 666 7777".trim() ;
    final Intent phoneIntent = new Intent(Intent.ACTION_DIAL);
    phoneIntent.setData(Uri.parse(uri));
    return phoneIntent;
}
//Checking
if ( !checkIntent(intent) ) {
            textview.setAutoLinkMask(0);
}
//be sure that you call setText after this
