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 |
