Android – Listing all extras of an Intent

androidandroid-intent

For debugging reasons I want to list all extras (and their values) of an Intent. Now, getting the keys isn't a problem

Set<String> keys = intent.getExtras().keySet();

but getting the values of the keys is one for me, because some values are strings, some are boolean… How could I get the values in a loop (looping through the keys) and write the values to a logfile? Thanks for any hint!

Here's what I used to get information on an undocumented (3rd-party) intent:

Bundle bundle = intent.getExtras();
if (bundle != null) {
    for (String key : bundle.keySet()) {
        Log.e(TAG, key + " : " + (bundle.get(key) != null ? bundle.get(key) : "NULL"));
    }
}

Make sure to check if bundle is null before the loop.

First, get the intent which has started your activity using the getIntent() method:

Intent intent = getIntent();

If your extra data is represented as strings, then you can use intent.getStringExtra(String name) method. In your case:

String id = intent.getStringExtra("id");
String name = intent.getStringExtra("name");

UPDATE

Official approach:

public void composeEmail(String[] addresses, String subject) {
    Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

OLD ANSWER

The accepted answer doesn't work on the 4.1.2. This should work on all platforms:

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
            "mailto","abc@gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body");
startActivity(Intent.createChooser(emailIntent, "Send email..."));

Update: According to marcwjj, it seems that on 4.3, we need to pass string array instead of a string for email address to make it work. We might need to add one more line:

intent.putExtra(Intent.EXTRA_EMAIL, addresses); // String[] addresses
