After the above files are compiled, the application can run correctly on the Android2.1 simulator.
What if the app runs on android1.6? 1.6 does not have the ContactsContract class system, so an error will be reported. Note that the ContactContract class is added in API Level 5, which is not supported in earlier Android versions.

Once we've created the list, we need to add some of the fields we need in the user Information table, and of course we can add more fields, and here we simply do an example of how to create a field bar in a custom list .Let's create a field "name" first.Open the User information table created in front of us, click on the blank position of the list, in the upper left corner will show a number of buttons, click on the " list" tab, click on the list Settings,Go to the Settings page, locate the colu

Android test plan. Just visit G.co/androidbeta and choose an optional Android phone or tablet – you'll soon receive a preview update for this version (or later). If you have already registered your device, you will soon receive updates and do not need you to do anything. Also you can manually download and refresh. Developer Preview 2 is intended for use by developers rather than as a daily use, and this ve
When you contact this tutorial, the method used to select a contact is to read the contact from the database, and then display it with listview. After selecting the contact, the mobile phone number is returned,
In this way, when you click to select a contact, it takes time t
contactnumber, @NonNull string contactname) {
Mtext.settext ( ContactName + contactnumber);
}
@Override public
void onfailed (@NonNull int errcode, @NonNull String message) {
Mtext.settext (errcode + message) ;
}
});
You need to have an anonymous inner class that will return Onsuccess and Onfailed methods, and then for contacts and phone numbers, you can do the relevant presentation.
