在我的 Android 应用程序中,我想在官方 Facebook 应用程序中打开指向 Facebook 个人资料的链接(当然,如果安装了该应用程序)。对于 iPhone,存在fb://
URL 方案,但在我的 Android 设备上尝试相同的操作会引发ActivityNotFoundException
.
是否有机会通过代码在官方 Facebook 应用程序中打开 Facebook 个人资料?
在我的 Android 应用程序中,我想在官方 Facebook 应用程序中打开指向 Facebook 个人资料的链接(当然,如果安装了该应用程序)。对于 iPhone,存在fb://
URL 方案,但在我的 Android 设备上尝试相同的操作会引发ActivityNotFoundException
.
是否有机会通过代码在官方 Facebook 应用程序中打开 Facebook 个人资料?
这适用于最新版本:
使用此方法:
public static Intent getOpenFacebookIntent(Context context) {
try {
context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/<id_here>"));
} catch (Exception e) {
return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/<user_name_here>"));
}
}
如果用户安装了 Facebook 应用程序,这将打开它。否则,它将在浏览器中打开 Facebook。
编辑:由于版本 11.0.0.11.23 (3002850) Facebook App 不再支持这种方式,还有另一种方式,请查看 Jared Rummler 的以下回复。
在 Facebook 版本 11.0.0.11.23 (3002850) 中fb://profile/
不再fb://page/
起作用。我反编译了 Facebook 应用,发现可以使用fb://facewebmodal/f?href=[YOUR_FACEBOOK_PAGE]
. 这是我在生产中使用的方法:
/**
* <p>Intent to open the official Facebook app. If the Facebook app is not installed then the
* default web browser will be used.</p>
*
* <p>Example usage:</p>
*
* {@code newFacebookIntent(ctx.getPackageManager(), "https://www.facebook.com/JRummyApps");}
*
* @param pm
* The {@link PackageManager}. You can find this class through {@link
* Context#getPackageManager()}.
* @param url
* The full URL to the Facebook page or profile.
* @return An intent that will open the Facebook page/profile.
*/
public static Intent newFacebookIntent(PackageManager pm, String url) {
Uri uri = Uri.parse(url);
try {
ApplicationInfo applicationInfo = pm.getApplicationInfo("com.facebook.katana", 0);
if (applicationInfo.enabled) {
// http://stackoverflow.com/a/24547437/1048340
uri = Uri.parse("fb://facewebmodal/f?href=" + url);
}
} catch (PackageManager.NameNotFoundException ignored) {
}
return new Intent(Intent.ACTION_VIEW, uri);
}
这不是更容易吗?例如在 onClickListener 中?
try {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/426253597411506"));
startActivity(intent);
} catch(Exception e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.facebook.com/appetizerandroid")));
}
PS。从 http://graph.facebook.com/[userName] 获取您的 id(大数字)
对于 Facebook 页面:
try {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/" + pageId));
} catch (Exception e) {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + pageId));
}
对于 Facebook 个人资料:
try {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/" + profileId));
} catch (Exception e) {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + profileId));
}
...因为没有一个答案指出了区别
两者都在 Nexus 4 上使用 Facebook v.27.0.0.24.15 和 Android 5.0.1 进行了测试
这是 2016 年的方法。它效果很好,而且使用起来非常简单。
在查看 Facebook 发送的电子邮件如何打开 Facebook 应用程序后,我发现了这一点。
// e.g. if your URL is https://www.facebook.com/EXAMPLE_PAGE, you should
// put EXAMPLE_PAGE at the end of this URL, after the ?
String YourPageURL = "https://www.facebook.com/n/?YOUR_PAGE_NAME";
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(YourPageURL));
startActivity(browserIntent);
这是执行此操作的最简单代码
public final void launchFacebook() {
final String urlFb = "fb://page/"+yourpageid;
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(urlFb));
// If a Facebook app is installed, use it. Otherwise, launch
// a browser
final PackageManager packageManager = getPackageManager();
List<ResolveInfo> list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
if (list.size() == 0) {
final String urlBrowser = "https://www.facebook.com/"+pageid;
intent.setData(Uri.parse(urlBrowser));
}
startActivity(intent);
}
一种更可重用的方法。
这是我们通常在大多数应用程序中使用的功能。因此,这里有一段可重用的代码来实现这一点。
(在事实方面与其他答案类似。在此处发布只是为了简化并使实现可重用)
"fb://page/
不适用于较新版本的 FB 应用程序。您应该使用fb://facewebmodal/f?href=
较新的版本。(就像这里另一个答案中提到的那样)
这是一个完整的工作代码,目前存在于我的一个应用程序中:
public static String FACEBOOK_URL = "https://www.facebook.com/YourPageName";
public static String FACEBOOK_PAGE_ID = "YourPageName";
//method to get the right URL to use in the intent
public String getFacebookPageURL(Context context) {
PackageManager packageManager = context.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) { //newer versions of fb app
return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
} else { //older versions of fb app
return "fb://page/" + FACEBOOK_PAGE_ID;
}
} catch (PackageManager.NameNotFoundException e) {
return FACEBOOK_URL; //normal web url
}
}
如果已安装,此方法将返回正确的应用程序 url,如果未安装应用程序,则返回 web url。
然后按如下方式启动一个意图:
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
这就是你所需要的。
为此,我们需要“Facebook 页面 id”,您可以获取它:
你可以这样做:
String facebookId = "fb://page/<Facebook Page ID>";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId)));
或者您可以验证何时未安装 facebook 应用程序,然后打开 facebook 网页。
String facebookId = "fb://page/<Facebook Page ID>";
String urlPage = "http://www.facebook.com/mypage";
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId )));
} catch (Exception e) {
Log.e(TAG, "Application not intalled.");
//Open url web page.
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(urlPage)));
}
Pierre87 在 FrAndroid 论坛上对此进行了逆向工程,但我找不到任何官方描述它的地方,因此它必须被视为无证并且随时可能停止工作:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.facebook.katana", "com.facebook.katana.ProfileTabHostActivity");
intent.putExtra("extra_user_id", "123456789l");
this.startActivity(intent);
试试这个代码:
String facebookUrl = "https://www.facebook.com/<id_here>";
try {
int versionCode = getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) {
Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else {
Uri uri = Uri.parse("fb://page/<id_here>");
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
} catch (PackageManager.NameNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookUrl)));
}
截至2020 年 3 月,这一切正常。
private void openFacebookPage(String pageId) {
String pageUrl = "https://www.facebook.com/" + pageId;
try {
ApplicationInfo applicationInfo = getPackageManager().getApplicationInfo("com.facebook.katana", 0);
if (applicationInfo.enabled) {
int versionCode = getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
String url;
if (versionCode >= 3002850) {
url = "fb://facewebmodal/f?href=" + pageUrl;
} else {
url = "fb://page/" + pageId;
}
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
} else {
throw new Exception("Facebook is disabled");
}
} catch (Exception e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(pageUrl)));
}
}
经过大量测试,我找到了最有效的解决方案之一:
private void openFacebookApp() {
String facebookUrl = "www.facebook.com/XXXXXXXXXX";
String facebookID = "XXXXXXXXX";
try {
int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
if(!facebookID.isEmpty()) {
// open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
Uri uri = Uri.parse("fb://page/" + facebookID);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
// open Facebook app using facebook url
Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
} catch (PackageManager.NameNotFoundException e) {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
}
我的答案建立在 joaomgcd 广泛接受的答案之上。如果用户安装了 Facebook,但被禁用(例如通过使用 App Quarantine),此方法将不起作用。将选择 Twitter 应用程序的意图,但由于它被禁用,它将无法处理它。
代替:
context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));
您可以使用以下内容来决定要做什么:
PackageInfo info = context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
if(info.applicationInfo.enabled)
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));
else
return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/620681997952698"));
我找到的最佳答案,它工作得很好。
只需在浏览器中转到您在 Facebook 上的页面,右键单击,然后单击“查看源代码”,然后找到page_id
属性:您必须page_id
在最后一个反斜杠后面的这一行中使用此处:
fb://page/pageID
例如:
Intent facebookAppIntent;
try {
facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/1883727135173361"));
startActivity(facebookAppIntent);
} catch (ActivityNotFoundException e) {
facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://facebook.com/CryOut-RadioTv-1883727135173361"));
startActivity(facebookAppIntent);
}
Intent intent = null;
try {
getPackageManager().getPackageInfo("com.facebook.katana", 0);
String url = "https://www.facebook.com/"+idFacebook;
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href="+url));
} catch (Exception e) {
// no Facebook app, revert to browser
String url = "https://facebook.com/"+idFacebook;
intent = new Intent(Intent.ACTION_VIEW);
intent .setData(Uri.parse(url));
}
this.startActivity(intent);
截至2018 年 7 月,无论是否在所有设备上安装 Facebook 应用程序,它都能完美运行。
private void goToFacebook() {
try {
String facebookUrl = getFacebookPageURL();
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
private String getFacebookPageURL() {
String FACEBOOK_URL = "https://www.facebook.com/Yourpage-1548219792xxxxxx/";
String facebookurl = null;
try {
PackageManager packageManager = getPackageManager();
if (packageManager != null) {
Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");
if (activated != null) {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) {
facebookurl = "fb://page/1548219792xxxxxx";
}
} else {
facebookurl = FACEBOOK_URL;
}
} else {
facebookurl = FACEBOOK_URL;
}
} catch (Exception e) {
facebookurl = FACEBOOK_URL;
}
return facebookurl;
}
要从您的应用程序启动facebook 页面,让 urlString = "fb://page/your_fb_page_id"
启动facebook messenger让 urlString = "fb-messenger://user/your_fb_page_id"
FB page id 通常是数字。要获取它,请转到查找我的 FB ID输入您的个人资料网址,例如www.facebook.com/edgedevstudio然后单击“查找数字 ID”。
瞧,你现在有了你的 fb 数字 ID。将“your_fb_page_id”替换为生成的数字 ID
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(urlString))
if (intent.resolveActivity(packageManager) != null) //check if app is available to handle the implicit intent
startActivity(intent)
查看我打开 Facebook 特定页面的代码:
//ID initialization
ImageView facebook = findViewById(R.id.facebookID);
facebook.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String facebookId = "fb://page/327031464582675";
String urlPage = "http://www.facebook.com/MDSaziburRahmanBD";
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId)));
}catch (Exception e){
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(urlPage)));
}
}
});
我创建了一种将 facebook 页面打开到 facebook 应用程序的方法,如果应用程序不存在,则在 chrome 中打开
String socailLink="https://www.facebook.com/kfc";
Intent intent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = Utils.getFacebookUrl(getActivity(), socailLink);
if (facebookUrl == null || facebookUrl.length() == 0) {
Log.d("facebook Url", " is coming as " + facebookUrl);
return;
}
intent.setData(Uri.parse(facebookUrl));
startActivity(intent);
Utils.class添加这些方法
public static String getFacebookUrl(FragmentActivity activity, String facebook_url) {
if (activity == null || activity.isFinishing()) return null;
PackageManager packageManager = activity.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) { //newer versions of fb app
Log.d("facebook api", "new");
return "fb://facewebmodal/f?href=" + facebook_url;
} else { //older versions of fb app
Log.d("facebook api", "old");
return "fb://page/" + splitUrl(activity, facebook_url);
}
} catch (PackageManager.NameNotFoundException e) {
Log.d("facebook api", "exception");
return facebook_url; //normal web url
}
}
还有这个
/***
* this method used to get the facebook profile name only , this method split domain into two part index 0 contains https://www.facebook.com and index 1 contains after / part
* @param context contain context
* @param url contains facebook url like https://www.facebook.com/kfc
* @return if it successfully split then return "kfc"
*
* if exception in splitting then return "https://www.facebook.com/kfc"
*
*/
public static String splitUrl(Context context, String url) {
if (context == null) return null;
Log.d("Split string: ", url + " ");
try {
String splittedUrl[] = url.split(".com/");
Log.d("Split string: ", splittedUrl[1] + " ");
return splittedUrl.length == 2 ? splittedUrl[1] : url;
} catch (Exception ex) {
return url;
}
}
在不使用 facebook sdk 的情况下在按钮单击事件上打开 fb
Intent FBIntent = new Intent(Intent.ACTION_SEND);
FBIntent.setType("text/plain");
FBIntent.setPackage("com.facebook.katana");
FBIntent.putExtra(Intent.EXTRA_TEXT, "The text you wanted to share");
try {
context.startActivity(FBIntent);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(context, "Facebook have not been installed.", Toast.LENGTH_SHORT).show( );
}
1-要获取您的 ID,请转到您的图像配置文件,然后单击右键并复制链接地址。
try {
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("fb://profile/id"));
startActivity(intent);
} catch(Exception e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("facebook url")));
}
}
});
声明常量
private String FACEBOOK_URL="https://www.facebook.com/approids";
private String FACEBOOK_PAGE_ID="approids";
声明方法
public String getFacebookPageURL(Context context) {
PackageManager packageManager = context.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
boolean activated = packageManager.getApplicationInfo("com.facebook.katana", 0).enabled;
if(activated){
if ((versionCode >= 3002850)) {
Log.d("main","fb first url");
return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
} else {
return "fb://page/" + FACEBOOK_PAGE_ID;
}
}else{
return FACEBOOK_URL;
}
} catch (PackageManager.NameNotFoundException e) {
return FACEBOOK_URL;
}
}
调用函数
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(MainActivity.this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
您可以检查是否安装了任何 Facebook 应用程序的所有 Facebook 应用程序。为了支持 OS 级别 11,我们需要添加它AndrodiManifest.xml
以避免找不到包名称异常 -
<manifest ...
<queries>
<package android:name="com.facebook.katana" />
<package android:name="com.facebook.lite" />
<package android:name="com.facebook.android" />
<package android:name="com.example.facebook" />
</queries>
<application .....
然后将此方法添加到您的代码中 -
public static String isFacebookAppInstalled(Context context){
if(context!=null) {
PackageManager pm=context.getPackageManager();
ApplicationInfo applicationInfo;
//First check that if the main app of facebook is installed or not
try {
applicationInfo = pm.getApplicationInfo("com.facebook.katana", 0);
return applicationInfo.enabled?"com.facebook.katana":"";
} catch (Exception ignored) {
}
//Then check that if the facebook lite is installed or not
try {
applicationInfo = pm.getApplicationInfo("com.facebook.lite", 0);
return applicationInfo.enabled?"com.facebook.lite":"";
} catch (Exception ignored) {
}
//Then check the other facebook app using different package name is installed or not
try {
applicationInfo = pm.getApplicationInfo("com.facebook.android", 0);
return applicationInfo.enabled?"com.facebook.android":"";
} catch (Exception ignored) {
}
try {
applicationInfo = pm.getApplicationInfo("com.example.facebook", 0);
return applicationInfo.enabled?"com.example.facebook":"";
} catch (Exception ignored) {
}
}
return "";
}
然后启动应用程序 -
if (!TextUtils.isEmpty(isFacebookAppInstalled(context))) {
/* Facebook App is installed,So launch it.
It will return you installed facebook app's package
name which will be useful to launch the app */
Uri uri = Uri.parse("fb://facewebmodal/f?href=" + yourURL);
Intent intent = context.getPackageManager().getLaunchIntentForPackage(isFacebookAppInstalled(context);
if (intent != null) {
intent.setAction(Intent.ACTION_VIEW);
intent.setData(uri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
else {
Intent intentForOtherApp = new Intent(Intent.ACTION_VIEW, uri);
context.startActivity(intentForOtherApp);
}
}
在 2018 年 10 月回答这个问题。工作代码是使用 pageID 的代码。我刚刚对其进行了测试,它可以正常工作。
public static void openUrl(Context ctx, String url){
Uri uri = Uri.parse(url);
if (url.contains(("facebook"))){
try {
ApplicationInfo applicationInfo = ctx.getPackageManager().getApplicationInfo("com.facebook.katana", 0);
if (applicationInfo.enabled) {
uri = Uri.parse("fb://page/<page_id>");
openURI(ctx, uri);
return;
}
} catch (PackageManager.NameNotFoundException ignored) {
openURI(ctx, uri);
return;
}
}
我在 webview 中使用 fragment- inside oncreate 以这种形式实现:
webView.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView viewx, String urlx)
{
if(Uri.parse(urlx).getHost().endsWith("facebook.com")) {
{
goToFacebook();
}
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlx));
viewx.getContext().startActivity(intent);
return true;
}
});
在 onCreateView 之外:
private void goToFacebook() {
try {
String facebookUrl = getFacebookPageURL();
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
//facebook url load
private String getFacebookPageURL() {
String FACEBOOK_URL = "https://www.facebook.com/pg/XXpagenameXX/";
String facebookurl = null;
try {
PackageManager packageManager = getActivity().getPackageManager();
if (packageManager != null) {
Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");
if (activated != null) {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) {
facebookurl = "fb://page/XXXXXXpage_id";
}
} else {
facebookurl = FACEBOOK_URL;
}
} else {
facebookurl = FACEBOOK_URL;
}
} catch (Exception e) {
facebookurl = FACEBOOK_URL;
}
return facebookurl;
}
fun getOpenFacebookIntent(context: Context, url: String) {
return try {
context.packageManager.getPackageInfo("com.facebook.katana", 0)
context.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/$url/")))
} catch (e: Exception) {
context.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse(url)))
}
}
答案对我有用,但缺少的一件事是在清单中添加查询,这是我的解决方案:
private void openFacebookApp() {
String facebookUrl = "www.facebook.com/XXXXXXXXXX";
String facebookID = "XXXXXXXXX";
try {
int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
if(!facebookID.isEmpty()) {
// open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
Uri uri = Uri.parse("fb://page/" + facebookID);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
// open Facebook app using facebook url
Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
} catch (PackageManager.NameNotFoundException e) {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
}
并将其添加到应用程序标签之外的清单中
<queries>
<package android:name="com.google.android.gm" />
<package android:name="com.facebook.katana" />

try {
String[] parts = url.split("//www.facebook.com/profile.php?id=");
getPackageManager().getPackageInfo("com.facebook.katana", 0);
startActivity(new Intent (Intent.ACTION_VIEW, Uri.parse(String.format("fb://page/%s", parts[1].trim()))));
} catch (Exception e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
}
您可以点击按钮打开 Facebook 应用程序,如下所示:-
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startNewActivity("com.facebook.katana");
}
});
}
public void startNewActivity( String packageName)
{
Intent intent = MainActivity.this.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent != null)
{
// we found the activity
// now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
else
{
// bring user to the market
// or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id="+packageName));
startActivity(intent);
}
}
