How to check if Facebook is installed Android
AndroidFacebookPackageAndroid Problem Overview
I am modifying my app to be able to catch if a user tries to publish without having the facebook app installed (required for SSO). Here is the code I am using:
try{
ApplicationInfo info = getPackageManager().
getApplicationInfo("com.facebook.android", 0 );
return true;
} catch( PackageManager.NameNotFoundException e ){
return false;
}
The problem is, it is always catching an error. According to the question here, I need to request the appropriate permission but I don't know what permissions I need to request.
Is my problem a permission one or something else?

com.facebook.android
is the package name for the Facebook SDK. The Facebook app's package is com.facebook.katana
.
Solution 2 - Android
To check whether or not an app is installed on Android use this method:
public static boolean isPackageInstalled(Context c, String targetPackage) {
PackageManager pm = c.getPackageManager();
try {
PackageInfo info = pm.getPackageInfo(targetPackage, PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
return false;
}
return true;
}
In your case use any of these packages:
- com.facebook.orca
- com.facebook.katana
- com.example.facebook
- com.facebook.android
boolean hasPackage = isPackageInstalled(MainActivity.this, "com.facebook.katana");
-
For Kotlin
fun isPackageInstalled(packageName: String, context: Context): Boolean { return try { val packageManager = context.packageManager packageManager.getPackageInfo(packageName, 0) true } catch (e: PackageManager.NameNotFoundException) { false } }
Solution 3 - Android
if (isAppInstalled()) {
Toast.makeText(getApplicationContext(), "facebook app already installed", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "facebook app not installing", Toast.LENGTH_SHORT).show();
}
public boolean isAppInstalled() {
try {
getApplicationContext().getPackageManager().getApplicationInfo("com.facebook.katana", 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
Solution 4 - Android
Write the function in Utilities or anywhere suit for you.This will function will help you to check any app installed or not.let me say for myself it is in Utilities.java
public static boolean isAppInstalled(Context context, String packageName) {
try {
context.getPackageManager().getApplicationInfo(packageName, 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
Then, Call this function from anywhere. for eg to check facebook app
if(Utilities.isAppInstalled(getApplicationContext(), "com.facebook.katana")) {
// Do something
}else {
Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.facebook.katana"));
startActivity(i);
}
Enjoy

Best Approach is to pick the package name including com.facebook but anyway you may use following packages:
- com.facebook.orca
- com.facebook.katana
- com.example.facebook
- com.facebook.android
Solution 6 - Android
You can check it for all Facebook Apps that any of Facebook apps are installed or not .
For supporting OS level 11 we need to add this in AndrodiManifest.xml
to avoid package name not found exception -
<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 .....
Then add this method to you code -
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 "";
}
And then launch the app -
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);
}
}

Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.facebook.katana"));
startActivity(i);
this code worked for me
Solution 8 - Android
if (isAppInstalled()) {
Toast.makeText(getApplicationContext(), "facebook app already installed", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "facebook app not installing", Toast.LENGTH_SHORT).show();
}
public boolean isAppInstalled() {
try {
getApplicationContext().getPackageManager().getApplicationInfo("com.facebook.katana", 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
Solution 9 - Android
myWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.e("tag","url override url = "+ url);
if( url.startsWith("http:") || url.startsWith("https:") ) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity( intent );
return true;
}
});
