02_电话拨号器intent说明
怎么在第一个Activity打开第二个Activity？在一个Activity中打开另外一个Activity，实际上之前已经做过，就是电话拨号器。
package com.itheima.callnewactivity; import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View; public class MainActivity extends Activity { @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
} public void call(View v){
Intent intent = new Intent();
//给意图设置一个动作
intent.setAction(Intent.ACTION_CALL);
//给意图设置数据
intent.setData(Uri.parse("tel:"+110));
//打开打电话的activity
startActivity(intent); } }

系统上层所有应用的源代码，实际上就是跟电话还有短信这些相关的。Browser是浏览器，Launcher2是桌面的这个应用。
实际上你最开始运行起来就是这个桌面，这个桌面对应的也是一个安卓应用。这个应用它的作用就是把其他的应用跑起来。
Mms是短信的，PackageInstaller是包安装器。咱们装应用的时候都会出来一个界面，这个界面介绍当前你装的东西是什么名字，会用到哪些权限，这个东西就是这个PackageInstaller。
Phone就是打电话的。
TelephonyProvider就是提供跟电话相关的一些信息。内容提供者相关。
Settings 设置的。
每调起一个应用默认都会在All messages(no filters)帮咱们打一个log，就是我调起来的是谁。
ActivityManager，通过它就可以看到我究竟都打开了哪一些应用。
<activity android:name="OutgoingCallBroadcaster"
android:permission="android.permission.CALL_PHONE"
android:theme="@android:style/Theme.NoDisplay"
android:configChanges="orientation|keyboardHidden">
<!-- CALL action intent filters, for the various ways
of initiating an outgoing call. -->
<intent-filter>
<action android:name="android.intent.action.CALL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
<intent-filter android:icon="@drawable/ic_launcher_sip_call">
<action android:name="android.intent.action.CALL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="sip" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="voicemail" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/phone" />
<data android:mimeType="vnd.android.cursor.item/phone_v2" />
<data android:mimeType="vnd.android.cursor.item/person" />
</intent-filter>
</activity>
它声明了一个CALL_PHONE的权限，所以你调起这个activity的时候必须在你的应用申请对应的权限。
数据以tel开头和scheme对上了。
<intent-filter>
<action android:name="android.intent.action.CALL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
通过startActivity就可以把当前的这个intent-filter所对应的Activity给它打开。
PHONE这个系统上层的应用的源代码的清单文件是：
