    <p>I have the following piece of code in my Android application that looks up a contacts ID, I have just changed the target from 1.5 to 2.2 but with a min SDK of 3 (1.5) so that I can use the ContactsContract Uri in 2.2 and the People Uri in 1.5.</p> <p>However the code leads to the following error when run on 1.5 devices:</p> <pre><code>07-27 15:02:53.382: WARN/dalvikvm(12656): VFY: unable to resolve static field 25 (CONTENT_URI) in Landroid/provider/ContactsContract$Contacts; </code></pre> <hr> <p>From google I have garnered that I need to use reflection in this case to allow the application run on both versions of Android?</p> <p>I have seen example's of how to use reflection to use methods of multiple/different versions but how can I use it in mycase where I want to use the ContactsContract Uri?</p> <p>Here is my code:</p> <hr> <pre><code>findViewById(R.id.contactimage).setOnClickListener(new OnClickListener() { public void onClick(View v) { String sdk = android.os.Build.VERSION.SDK; Uri contactUri; Log.d("CDA", "Contact ID Button pressed = " + contactId); if(sdk.equals("8")){ contactUri = ContentUris.withAppendedId (ContactsContract.Contacts.CONTENT_URI, contactId); Intent intent = new Intent(Intent.ACTION_VIEW, contactUri); startActivity(intent); } else{ contactUri = ContentUris.withAppendedId (People.CONTENT_URI, contactId); Intent intent = new Intent(Intent.ACTION_VIEW, contactUri); startActivity(intent); } dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.FLAG_SOFT_KEYBOARD)); dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK)); } }); </code></pre> <hr> <p>EDIT:</p> <p>Here is an example of how its done:</p> <pre><code>private static Uri CONTENT_URI=null; private static String NAME_URI=null; private static String ID_URI=null; private static String NUMBER_URI = null; private static Uri PHONE_LOOKUP = null; static int sdk; static { sdk=new Integer(Build.VERSION.SDK).intValue(); if (sdk&gt;=5) { try { Class clazz=Class.forName("android.provider.ContactsContract$CommonDataKinds$Phone"); Class clazz_phonelookup=Class.forName("android.provider.ContactsContract$PhoneLookup"); NAME_URI=(String)clazz.getField("DISPLAY_NAME").get(clazz); ID_URI=(String)clazz.getField("_ID").get(clazz); NUMBER_URI=(String)clazz.getField("NUMBER").get(clazz); PHONE_LOOKUP =(Uri)clazz_phonelookup.getField("CONTENT_FILTER_URI").get(clazz); } catch (Throwable t) { Log.e("reflection", "Exception when determining CONTENT_URI", t); } } else { CONTENT_URI=Contacts.People.CONTENT_URI; NAME_URI=People.NAME; ID_URI=People._ID; NUMBER_URI=People.NUMBER; PHONE_LOOKUP = null; } } </code></pre>

    1. COYou'll have to wrap any of the SDK-version-specific code in a wrapper class, most likely. This is a duplicate of this SO question from 5 months ago, though: http://stackoverflow.com/questions/2312321/how-to-use-contacts-api-for-android-1-x-and-2-x-simultaneously

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
