1. A little sentiment
These two days of programming every day a null pointer exception, can not find the activity of what the exception, in short, a variety of not compile the implementation of the Times wrong exception, and in the written apk application escalation error, I was puzzled, Java anyhow to mention a mistake, Android is always unknown, this makes me very depressed, Although Android also has a special console output to indicate the various results bar ... But the tip is always Yixieqi

Tuto: Modification of a dialer
Hello everyone,
This tuto allowing to intervene directly on the resources of your dialer. ie DLL.
Advantages: no additional resource, only those origins. So, not one gram of fat added. a
Android4.4 Telephony Process Analysis-call record loading process of dial-up applications (Dialer)
The code in this article takes the MTK platform Android 4.4 as the analysis object, which is somewhat different from Google's native AOSP. Please be aware of it.
The call history of the Android system is stored in the CALS table of the contact database contacts2.db. When the call record (calllog) is stored in the database, you can view my previous blog
This article describes the development of Android Phone Dialer and SMS transmitter implementation methods. Share to everyone for your reference, specific as follows:
Phone Dialer
Realization principle: The user enters the telephone number, when clicks dials, by listens for the object capture, listens for the object through the text control obtains to the user to enter the telephone number, because the sys

This thought is a simple telephone dialer, or learned a lot of things, so still learned a lot of things, understand the Android permissions Uri.parse several uses:Not much to say on the code:Package Com.djf.phone;import Android.app.activity;import Android.content.intent;import android.net.Uri;import Android.os.bundle;import Android.text.textutils;import Android.view.view;import Android.widget.EditText;import Android.widget.toast;public class Mainactiv
Feel:1. Learned about the action and URI in intent.2. Understand the next activity passing data.3. Understand the content provider.4. Learn about custom adapters.4.

activity in the program, we often use implicit invocation, that is, we do not directly specify the activity to jump, but instead provide some relevant parameters for intent. Let it automatically match the activity already in the Androidmanifest.xml (StartActivity () method is used here to implement the matching process), and Intentfilter (Intent filter) There are three main parameters in XML: Action,categary,data. For implicitly called Intent,android the default is to add a category_default, so
