Android Attaching A File To GMAIL - Can't Attach Empty File


Answer :

Ok, got it to work now, after a lot of research and intercepting some Intents.

What I had to do was change the file:/// to content://.

I did this following this information from Android: https://developer.android.com/reference/android/support/v4/content/FileProvider.html

The only major change was that I used a hard-coded path to /sdcard/file.ext. Also, the line

getUriForFile(getContext(), "com.mydomain.fileprovider", newFile);

was changed to

Uri contentUri = FileProvider.getUriForFile(this, "com.mydomain.fileprovider", newFile);

Also had to include:

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION); i.setData(contentUri);

I do not really understand why I had to change from File to Content, but after this, the file is now being attached again! See the link if you face this issue, and don't forget about the new .xml that needs to be created.


See the following question:

android-6-cannot-share-files-anymore

This behavior is with Android 6.0 and Gmail. Please see the following thread.

Issue 3141 - android-developer-preview

If you go to Settings->Apps->Gmail->Permissions and enable the "Storage" permission manually, then the share works.

Gmail should ask for "Storage" permission in this scenario and it would work as it did in all the past version of Android.

Other email apps should handle attachments correctly.


Here is how to fix it.

Go to Settings -> Apps -> Gmail -> Permissions Turn on the permission for "Storage" That work-around solved the issue for me.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
