使用启用CustomTabIntent的应用程序打开AppLink

Question

我正试图在我的应用程序中添加CustomTabIntent以打开我的网站的网址。问题是我已经将AppLinking实现到我的应用程序中，因为它没有出现chrome，所以它被重定向到我的deeplink处理程序类，它将我的url重定向到Chrome。

我为CustomTabIntent使用了以下代码，

CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder()
            .setToolbarColor(ContextCompat.getColor(this, R.color.colorPrimary))
            .setSecondaryToolbarColor(ContextCompat.getColor(this, R.color.colorPrimaryDark))
            .setShowTitle(true)
            .addDefaultShareMenuItem()
            .setStartAnimations(this, R.anim.slide_in_right, R.anim.slide_out_left)
            .setExitAnimations(this, android.R.anim.slide_in_left,
                    android.R.anim.slide_out_right);
    CustomTabsIntent customTabsIntent = builder.build();
    customTabsIntent.launchUrl(this, Uri.parse(url));

它们是我可以绕过applink打开CustomTabIntent的一种方式吗？

是的，您可以通过访问CustomTabsIntent中的内部意图并调用setPackageName来设置要打开的应用程序的包名。

String packageName = "...";
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder()
        .setToolbarColor(ContextCompat.getColor(this, R.color.colorPrimary))
        .setSecondaryToolbarColor(ContextCompat.getColor(this, R.color.colorPrimaryDark))
        .setShowTitle(true)
        .addDefaultShareMenuItem()
        .setStartAnimations(this, R.anim.slide_in_right, R.anim.slide_out_left)
        .setExitAnimations(this, android.R.anim.slide_in_left,
                android.R.anim.slide_out_right);
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.intent.setPackage(packageName);
customTabsIntent.launchUrl(this, Uri.parse(url));

从现在开始，您一定想知道如何在打开“自定义”选项卡时设置哪个包名。即使您可以对特定浏览器的包名进行硬编码，例如：

customTabsIntent.intent.setPackageName("com.android.chrome");

但是，由于火狐和三星等其他浏览器也支持CustomTabs，所以理想情况下，您需要了解安装了哪些浏览器并使用其中之一。

下面的代码可以帮助实现这一点：

public static ArrayList getCustomTabsPackages(Context context) {
    PackageManager pm = context.getPackageManager();
    // Get default VIEW intent handler.
    Intent activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.example.com"));

    // Get all apps that can handle VIEW intents.
    List resolvedActivityList = pm.queryIntentActivities(activityIntent, 0);
    ArrayList packagesSupportingCustomTabs = new ArrayList<>();
    for (ResolveInfo info : resolvedActivityList) {
        Intent serviceIntent = new Intent();
        serviceIntent.setAction(ACTION_CUSTOM_TABS_CONNECTION);
        serviceIntent.setPackage(info.activityInfo.packageName);
        // Check if this package also resolves the Custom Tabs service.
        if (pm.resolveService(serviceIntent, 0) != null) {
            packagesSupportingCustomTabs.add(info);
        }
    }
    return packagesSupportingCustomTabs;
}

可以将它与CustomTabsClient.getPackageName结合使用来选择包。

多亏了这里和那里，我用Kotlin写了同样的文章。感谢阿加迪普的更新。

private fun getCustomTabsPackages(context: Context, url: String): List<ResolveInfo> {
    val pm: PackageManager = context.packageManager
    // Get default VIEW intent handler.
    val activityIntent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    // Get all apps that can handle VIEW intents.
    val resolvedActivityList: List<ResolveInfo> = pm.queryIntentActivities(activityIntent, 0)
    return resolvedActivityList.filter {
        val serviceIntent = Intent()
        serviceIntent.action = ACTION_CUSTOM_TABS_CONNECTION
        serviceIntent.setPackage(it.activityInfo.packageName)
        // Check if this package also resolves the Custom Tabs service.
        pm.resolveService(serviceIntent, 0) != null
    }
}

private fun showBrowser(url: String) {
    val customTabsPackages = getCustomTabsPackages(context!!, url)
    if (customTabsPackages.isNullOrEmpty()) {
        openAnyBrowser(url)
    } else {
        // Get the first Chrome-compatible browser from the list.
        val packageName = customTabsPackages.first().activityInfo.packageName
        openChromeTabs(packageName, url)
    }
}

private fun openAnyBrowser(url: String) {
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    if (intent.resolveActivity(context!!.packageManager) != null) {
        startActivity(intent)
    } else {
        showError("Cannot open web browser")
    }
}

private fun openChromeTabs(packageName: String, url: String) {
    val params = CustomTabColorSchemeParams.Builder()
        .setToolbarColor(ContextCompat.getColor(context, R.color.colorPrimary))
        .setSecondaryToolbarColor(ContextCompat.getColor(context, R.color.colorPrimaryDark))
        .setNavigationBarColor(ContextCompat.getColor(context, R.color.colorPrimary))
        .build()
    val builder = CustomTabsIntent.Builder()
        .setColorScheme(CustomTabsIntent.COLOR_SCHEME_DARK)
        .setColorSchemeParams(CustomTabsIntent.COLOR_SCHEME_DARK, params)
        //.setDefaultColorSchemeParams(params)
        .setShowTitle(true)
        .setShareState(SHARE_STATE_DEFAULT)
        .setStartAnimations(context, R.anim.slide_in_right, R.anim.slide_out_left)
        .setExitAnimations(context, android.R.anim.slide_in_left,
            android.R.anim.slide_out_right)
    val customTabsIntent = builder.build()
    customTabsIntent.intent.setPackage(packageName)
    customTabsIntent.launchUrl(context!!, Uri.parse(url))
}

在build.gradle中

// Chrome Custom Tabs.
implementation 'androidx.browser:browser:1.3.0'

在API 30 intent.resolveActivity(context!!.packageManager) 返回空中，如果您想显示其他浏览器，那么在AndroidManifest中添加以下几行：

<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="http" />
    </intent>
</queries>
