Android在应用中依据包名启动另外一个APP

以下为TestIntentData工程

MainActivity如下:

package cn.testintentdata;import java.util.List;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.app.Activity;import android.content.ComponentName;import android.content.Intent;import android.content.pm.PackageInfo;import android.content.pm.PackageManager.NameNotFoundException;import android.content.pm.ResolveInfo;/** * Demo描述: * 应用中依据包名启动另外一个APP * */public class MainActivity extends Activity {private Button mButton;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();}private void init(){mButton=(Button) findViewById(R.id.button);mButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View view) {startAnotherApp("cc.testintent");}});}private void startAnotherApp(String packageName){PackageInfo packageInfo = null;try {packageInfo = getPackageManager().getPackageInfo(packageName, 0);if (packageInfo==null) {System.out.println("packageInfo==null");} else {System.out.println("packageInfo!=null");}} catch (NameNotFoundException e) {e.printStackTrace();} //<data android:scheme="app" android:host="jp.co.cybird.barcodefootballer/" />Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);resolveIntent.setData(Uri.parse("app://jp.co.cybird.barcodefootballer/"));resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);resolveIntent.setPackage(packageInfo.packageName);System.out.println("packageInfo.packageName="+packageInfo.packageName);List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(resolveIntent, 0);System.out.println("resolveInfoList.size()="+resolveInfoList.size()); ResolveInfo resolveInfo = resolveInfoList.iterator().next();if (resolveInfo != null ) {String activityPackageName = resolveInfo.activityInfo.packageName;String className = resolveInfo.activityInfo.name; Intent intent = new Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);ComponentName componentName = new ComponentName(activityPackageName, className); intent.setComponent(componentName);startActivity(intent);}}}

 

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    >    <Button        android:id="@+id/button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="click me"         android:layout_centerInParent="true"        /></RelativeLayout>

以下为TestIntent工程

MainActivity如下:

package cc.testintent;import android.os.Bundle;import android.app.Activity;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);}}

 

main.xml如下:

<RelativeLayout     xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"   >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="大 家 好"        android:layout_centerInParent="true"    /></RelativeLayout>

AndroidManifest.xml如下:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="cc.testintent"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="8" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="cc.testintent.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <data android:scheme="app"/>                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>
