Android支持通过Url打开App，比如下面的Url
scheme://host/datastring
要打开这样的Url，首先在配置文件AndroidManifest.xml里使用<data>添加一种App打开的格式，代码如下

<?xml version=”1.0″ encoding=”utf-8″?>
<manifest xmlns:android=”http://schemas.android.com/apk/res/android”
  package=”com.sheng00.customuridemo”
  android:versionCode=”1″
  android:versionName=”1.0″ >
  <uses-sdk
    android:minSdkVersion=”9″
    android:targetSdkVersion=”17″ />
  <application
    android:allowBackup=”true”
    android:icon=”@drawable/ic_launcher”
    android:label=”@string/app_name”
    android:theme=”@style/AppTheme” >
    <activity
      android:name=”com.sheng00.customuridemo.MainActivity”
      android:label=”@string/app_name” >
      <intent-filter>
        <action android:name=”android.intent.action.MAIN” />
        <category android:name=”android.intent.category.LAUNCHER” />
      </intent-filter>
      <!– Open links like scheme://host/?… –>
      <intent-filter>
        <action android:name=”android.intent.action.VIEW” />
        <category android:name=”android.intent.category.DEFAULT” />
        <category android:name=”android.intent.category.BROWSABLE” />
        <data android:scheme=”scheme” android:host=”host” />
      </intent-filter>
    </activity>
  </application>
</manifest>

注意，第二个<intent-filter>中的data绑定了url 在页面中出现scheme://host/类似这样的链接，点击就可以直接打开app app中处理链接地址代码如下

package com.sheng00.customuridemo;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
  }
  @Override
  protected void onResume() {
    super.onResume();
    Intent intent = getIntent();
    if (intent != null) {
      String action = intent.getAction();
      String dataString = intent.getDataString();
      if(dataString!=null){
        TextView tv = (TextView) findViewById(R.id.tv);
        tv.append("n" + dataString);
      }
    }
  }
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
  }
}
