Listing all extras of an 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!

Solution 1:

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.

Solution 2:

This is how I define utility method to dump all extras of an Intent.

import java.util.Iterator;
import java.util.Set;
import android.os.Bundle;


public static void dumpIntent(Intent i){

    Bundle bundle = i.getExtras();
    if (bundle != null) {
        Set<String> keys = bundle.keySet();
        Iterator<String> it = keys.iterator();
        Log.e(LOG_TAG,"Dumping Intent start");
        while (it.hasNext()) {
            String key = it.next();
            Log.e(LOG_TAG,"[" + key + "=" + bundle.get(key)+"]");
        }
        Log.e(LOG_TAG,"Dumping Intent end");
    }
}
