Hi, i just tried your piece of code and when i push the button “DIAL” the call doesn’t start.
In the console windows i got following message in last line
[2010-08-27 14:39:12 - AndroidProject] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.cube/.AndroidProject }

What ’s wrong?

If you want to be able to dial MMI/USSD codes from this script, you will need to make the following changes.

First add these permissions to the android manifest:
android.permission.CALL_PHONE
android.permission.CALL_PRIVILEGED android.permission.MODIFY_PHONE_STATE

and alter the dialing line to Uri encode “#” and “*” characters.

Change this line:

startActivity(new Intent(Intent.ACTION_CALL, Uri.parse(“tel:” + mEditText_number.getText())));

to:

startActivity(new Intent(Intent.ACTION_CALL, Uri.parse(“tel:” + Uri.encode(mEditText_number.getText().toString()))));

I hope that helps anyone trying to send MMI/USSD codes.

For those of you, who have trouble geting it to actually dial.
What is missing is that you need to add a permission in the AndroidManifest.xml

add this code to the manifest, at the end, right before

you can also click the Permissions tab, click the button Add, then in the namelist choose, android.permission.CALL_PHONE and the code will get added in the manifest.

this shuld make your appication call the number enterd.

Hey,

Thanks for the code snippet! I’ve actually started a blog devoted to code snippets like these and thought I’d reach out and maybe you could check it out?

http://thinkandroid.wordpress.com

It’s a pretty young blog (~ 3 weeks old now) but it’s doing pretty well… getting about 200-300 hits a day. And yea I’ve wanted to reach out to other blogs/sites like mine to help connect my site with others and ultimately help developers reach my site for potentially useful tutorials or examples.

But yes let me know what you think! Hope to hear back!
