Android app中调用启动其他应用（系统应用和第三方应用）

一、打开第三方应用

方法一

Intent intent=new Intent();
//包名 包名+类名（全路径）
intent.setClassName("com.linxcool", "com.linxcool.PlaneActivity");
startActivity(intent);

方法二

Intent intent = new Intent();
ComponentName comp = new ComponentName("com.linxcool","com.linxcool.PlaneActivity");
intent.setComponent(comp);
intent.setAction("android.intent.action.MAIN");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

方法三

出自storm的博客。
这段代码会检测app是否安装，没安装的话会指向商店下载。

public static final String APP_PACKAGE_NAME = "com.*.*";//包名

/**
* 启动薄荷App
* @param context
*/
public static void launchapp(Context context) {
// 判断是否安装过App，否则去市场下载
if (isAppInstalled(context, APP_PACKAGE_NAME)) {
context.startActivity(context.getPackageManager().getLaunchIntentForPackage(APP_PACKAGE_NAME));
} else {
goToMarket(context, APP_PACKAGE_NAME);
}
}

/**
* 检测某个应用是否安装
*
* @param context
* @param packageName
* @return
*/
public static boolean isAppInstalled(Context context, String packageName) {
try {
context.getPackageManager().getPackageInfo(packageName, 0);
return true;
} catch (NameNotFoundException e) {
return false;
}
}

/**
* 去市场下载页面
*/
public static void goToMarket(Context context, String packageName) {
Uri uri = Uri.parse("market://details?id=" + packageName);
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
try {
context.startActivity(goToMarket);
} catch (ActivityNotFoundException e) {
}
}

调用第三方应用的关键在于获得第三方应用的包名和入口Activity类名。

获得获得第三方应用的包名和入口Activity类名

使用aapt
//aapt是sdk自带的一个工具，在sdk\builds-tools\目录下
1.以ES文件浏览器为例，命令行中切换到aapt.exe目录执行：aapt dump badging E:\apk\es3.apk
2.运行后的结果中以下两行分别是应用包名package和入口activity名称
package: name=’com.estrongs.android.pop’//在输出比较靠前的位置
launchable-activity: name=’com.estrongs.android.pop.view.FileExplorerActivity’
注：在android sdk目录搜索可以找到aapt.exe，如果没有可以下载apktool。

查看AndroidManifest.xml
1.使用apktool反编译app：apktool.bat d es3.apk E:\apk\es
2.打开AndroidManifest.xml
manifest节点的package属性值是应用的包名：
查找android.intent.action.MAIN和android.intent.category.LAUNCHER对应的activity，该activity对应的android:name属性既是入口activity名称，如下：

<activity android:theme=”@android:tyle/Theme.NoTitleBar” android:label=”@string/app_name” android:name=”com.estrongs.android.pop.view.FileExplorerActivity”>
<intent-filter>
<action android:name=”android.intent.action.MAIN” />
<category android:name=”android.intent.category.LAUNCHER” />
</intent-filter>
</activity>

android.intent.action.MAIN决定应用程序最先启动的Activity，android.intent.category.LAUNCHER决定应用程序是否显示在
程序列表里。

顺便分享几个应用的包名和入口Activity(用aapt获得的)：

app	package	launcher
微博	com.sina.weibo	com.sina.weibo.SplashActivity
知乎	com.zhihu.android	com.zhihu.android.ui.activity.GuideActivity
薄荷	com.app.one	com.app.one.ui.SplashActivity
