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：
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 |
