Question

How i can pick mp3 file from sdcard in android preferenceScreen menu..

here is my preferenceScreen:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
        <PreferenceCategory android:title="@string/app_setting">

            <Preference android:title="@string/ChooseRingtone"

            addPreferencesFromResource(R.xml.pref);

            Preference sdPrefs = findPreference("sdPref");
            sdPrefs.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
                @Override
                public boolean onPreferenceClick(Preference preference) {
                    return false;

Answer 1

Try below code for selecting only mp3 files,

       sdPrefs.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
            @Override
            public boolean onPreferenceClick(Preference preference) {

                 Intent intent_upload = new Intent();
                 //intent_upload.setType("audio/*"); // For All Audio Files
                 intent_upload.setType("audio/mp3"); // For only MP3 Files
                 intent_upload.setAction(Intent.ACTION_GET_CONTENT);
                 startActivityForResult(intent_upload,1);
                 return false;
            }
        });

in startActivityForResult second argument is not integer – Palanquin

its character sequnce – Palanquin

Second argument is unique id for checking response your get, and generally it is int, you can take it as declare first at top int PICK_SONG = 1, and then pass it as second argument, When you will get result in onActivityResult, you need to match this tag for proper response. – Footgear

hey is it possible to store selected mp3 file to raw directory? – Palanquin

nope you can't do it, instead of that you should store file path in db or preferences and use it, it will reduce memory and run faster. – Footgear
