梳理下流程：

枚举对应浏览器包名到数组中

数组循环根据包名找到对应的LaunchIntent

通过LaunchIntent找到对应的LaunchActivity的包名

Intent通过设置activity的包名+类名

/**

* 工具类

*/

public class CheckApkExist {

private static String ucPkgName = "com.uc.browser";

public static boolean checkApkExist(Context context, String packageName){

if (TextUtils.isEmpty(packageName))

return false;

try {

ApplicationInfo info = context.getPackageManager()

.getApplicationInfo(packageName,

PackageManager.GET_UNINSTALLED_PACKAGES);

return true;

} catch (PackageManager.NameNotFoundException e) {

return false;

}

}

/** 示例：uc 浏览器检测*/

public static boolean checkUCBrowserExist(Context context){

return checkApkExist(context, ucPkgName);

}

/**

* 从手机上搜索已安装浏览器程序打开网页,默认使用系统浏览器。

* 将 context 替换为当前上下文环境，ActivityClass or Context
