}
}

Answer 1

You may want to check whether your device can handle your intent by doing this:

PackageManager packageManager = getPackageManager();
if (intent.resolveActivity(packageManager) != null) {
    startActivity(intent);
} else {
     Log.d(TAG, "Cannot handle this intent");
}

What's more, if you are placing a call like so, there is NO need to declare the permission in your manifest:

<uses-permission android:name="android.permission.CALL_PHONE" />

Because you are not directly calling someone within your app. You are actually transferring the "duty" to other apps which can handle your intent to call. This doesn't need a permission.

To directly make a call within your app, the intent should be Intent.ACTION_CALL , which needs the permission you declared.

Hope this will help.

Answer 2

There is no activity on your device that handles ACTION_DIAL for a Tel: scheme. Try:

Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:9999999" ));

Case and whitespace are important when assembling a Uri .

Also note that even my revised Intent will not work on all devices, such as on an Android tablet that lacks a dialer.
