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 withfile:/
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.

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:
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7:
Check this useful method:
URLUtil.guessUrl(urlString)
It makes google.com -> http://google.com
回答8:
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9:
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10:
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.
