No Activity found to handle Intent : android.inten

问题:

This is my code to play the recorded audio 3gp file

 Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
        Uri data = Uri.parse(path);
        intent.setDataAndType(data, "audio/mp3");
        startActivity(intent);

But while running it in my HTC device (Android 2.2 Froyo) shows an exception:

05-04 16:37:37.597: WARN/System.err(4065): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=/mnt/sdcard/mnt/sdcard/audio-android.3gp typ=audio/mp3 }

In Galaxy tablet it's working fine. How can I resolve this issue?

回答1:

Url addresses must be preceded by http://

Uri uri = Uri.parse("www.google.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);

throws an ActivityNotFoundException. If you prepend "http://", problem solved.

Uri uri = Uri.parse("http://www.google.com");

May not help OP, but I ended up here searching for the same exception and maybe it helps others.

回答2:

This is the right way to do it.

    try
    {
    Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW);
    File file = new File(aFile.getAbsolutePath()); 
    String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString());
    String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    myIntent.setDataAndType(Uri.fromFile(file),mimetype);
    startActivity(myIntent);
    }
    catch (Exception e) 
    {
        // TODO: handle exception
        String data = e.getMessage();
    }

you need to import import android.webkit.MimeTypeMap;

回答3:

If you are also getting this error when trying to open a web page from your android app it is because your url looks like this:

www.google.com

instead of: https://www.google.com or http://www.google.com

add this code to your Activity/Fragment:

 public void openWebPage(String url) {

    Uri webpage = Uri.parse(url);

    if (!url.startsWith("http://") && !url.startsWith("https://")) {
        webpage = Uri.parse("http://" + url);
    }

    Intent intent = new Intent(Intent.ACTION_VIEW, webpage);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

just pass your url to openWebPage(). If it is already prefixed with https:// or http:// then you are good to go, else the if statement handles that for you

回答4:

Answer by Maragues made me check out logcat output. Appears that the path you pass to Uri needs to be prefixed with
file:/

Since it is a local path to your storage.

You may want too look at the path itself too.

`05-04 16:37:37.597: WARN/System.err(4065): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=/mnt/sdcard/mnt/sdcard/audio-android.3gp typ=audio/mp3 }`

Mount point seems to appear twice in the full path.

回答5:

For me when trying to open a link :

Uri uri = Uri.parse("https://www.facebook.com/abc/");
                Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                startActivity(intent);

I got the same error android.content.ActivityNotFoundException: No Activity found to handle Intent

The problem was because i didnt have any app that can open URLs (i.e. browsers) installed in my phone. So after Installing a browser the problem was solved.

*Lesson : Make sure there is at least one app which handles the intent you are calling *

回答6:

I had this same issue, so I was looking at the intent which is logged in LogCat. When viewing the video from the Gallery, it called the same Intent.View intent, but set the Type to "audio/*", which fixed my issue, and doesn't require importing MimeTypeMap. Example:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
Uri data = Uri.parse(path);
intent.setDataAndType(data, "audio/*");
startActivity(intent);

回答7:

If you don't pass the correct web URL and don't have a browser, ActivityNotFoundException occurs, so check those requirements or handle the exception explicitly. That can resolve your problem.

public static void openWebPage(Context context, String url) {
    try {
        if (!URLUtil.isValidUrl(url)) {
            Toast.makeText(context, " This is not a valid link", Toast.LENGTH_LONG).show();   
        } else {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(url));
            context.startActivity(intent);
        }
    } catch (ActivityNotFoundException e) {
        Toast.makeText(context, " You don't have any browser to open web page", Toast.LENGTH_LONG).show();
    }
}

回答8:

Had this exception even changed to

"audio/*"

But thanx to @Stan i have turned very simple but usefully solution:

Uri.fromFile(File(content)) instead Uri.parse(path)

 val intent =Intent(Intent.ACTION_VIEW)
                    intent.setDataAndType(Uri.fromFile(File(content)),"audio/*")
                    startActivity(intent)

Hope it helps somebody to fix his problem.

回答9:

If you have these error in your logcat then use these code it help me

 Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File(data.getLocation())), "audio/*");
            try {
                context.startActivity(intent);
            } catch (ActivityNotFoundException e) {
                Log.d("error", e.getMessage());
            }

also

   Intent intent = new Intent(MediaStore.INTENT_ACTION_MUSIC_PLAYER);
            intent.setDataAndType(Uri.fromFile(new File(data.getLocation())), "audio/*");
            try {
                context.startActivity(intent);
            } catch (ActivityNotFoundException e) {
                Log.d("error", e.getMessage());
            }

回答10:

check this useful method

URLUtil.guessUrl(urlString)

it makes google.com -> http://goolge.com

回答11:

I have two idea:

First: if you want play 3gp file you should use mime types "audio/3gpp" or "audio/mpeg"

And second: you can try use method setData(data) for intent without any mime type.

Hope this helps.
