I'm currently building an app that has Facebook and Instagram integration and I need to check whether the app has been installed on the user's device or not.
I've tried out :
private boolean appInstalledOrNot(String uri)
{
PackageManager pm = fragment.getContext().getPackageManager();
boolean app_installed = false;
try
{
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
}
catch (PackageManager.NameNotFoundException e)
{
app_installed = false;
}
return app_installed ;
}
And I've passed in "com.instagram.android" and "com.facebook.katana" (Facebook) as the URI for the package name.
My Code :
binding.facebook.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean haveApp = appInstalledOrNot("com.facebook.katana");
if (haveApp) {
LoginManager.getInstance().logInWithReadPermissions(SocialMediaSharingFragment.this, Arrays.asList("public_profile", "email"));
} else {
Toast.makeText(getContext(), "App not installed", Toast.LENGTH_SHORT).show();
}
}
});
I've deleted the Facebook App from my phone and ran the code, but somehow I'm still getting a true returned from the appInstalledOrNot method.
Did the same for Instagram as well, still doesn't work. I'm using DataBinding as you can see and I'm using it on a Fragment, not an Activity.
Would really appreciate help on this.
Thanks for reading...
Try to use another flag:
pm.getPackageInfo(uri, 0);
I'm opening links received in notifications in FB native app if it's installed on the app and in the browser otherwise, using this code:
PackageManager packageManager = context.getPackageManager();
try {
packageManager.getPackageInfo("com.facebook.katana", PackageManager.GET_ACTIVITIES);
return context.getString(R.string.fb_app_prefix) + fb_url;
} catch (PackageManager.NameNotFoundException e) {
return context.getString(R.string.fb_site_prefix) + fb_url; //normal web mUrl
}
It works on most devices (including the emulator), but in some of them it doesn't throw an error although the app isn't installed.
What's wrong with my code?
I can add the following code for every link I have but not sure it's "healthy":
Intent testIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(fb_app_url));
if (testIntent.resolveActivity(packageManager) != null) {
return fb_app_url;
}
public static boolean isPackageExisted(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;
}
I think the question says it all: What is the best way to find out if the user has installed Facebook or Whatsapp on his phone? Do I have to go over the package or what is the best way for this?
This was question was answered here. You can using the following piece of code to check for the package name
com.facebook.android OR com.facebook.katana
Code:
public class Example extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Put the package name here...
boolean installed = appInstalledOrNot("com.facebook.android");
if(installed)
{
//This intent will help you to launch if the package is already installed
Intent LaunchIntent = getPackageManager()
.getLaunchIntentForPackage("com.facebook.android");
startActivity(LaunchIntent);
System.out.println("App already installed om your phone");
}
else
{
System.out.println("App is not installed om your phone");
}
}
private boolean appInstalledOrNot(String uri)
{
PackageManager pm = getPackageManager();
boolean app_installed = false;
try
{
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
}
catch (PackageManager.NameNotFoundException e)
{
app_installed = false;
}
return app_installed ;
}
}
Can anyone say how to get an application id of market application installed in device. I want to get ID of particular installed application?
boolean installed = appInstalledOrNot(Your App Package as String);
if(installed){
////////App is Installed
}
private boolean appInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
How can I find whether a particular package or application, say: com.android.abc, exists on my Android device?
Call any of the below method with the package name.
import android.content.pm.PackageManager;
// ...
public boolean isPackageExisted(String targetPackage){
List<ApplicationInfo> packages;
PackageManager pm;
pm = getPackageManager();
packages = pm.getInstalledApplications(0);
for (ApplicationInfo packageInfo : packages) {
if(packageInfo.packageName.equals(targetPackage))
return true;
}
return false;
}
import android.content.pm.PackageManager;
public boolean isPackageExisted(String targetPackage){
PackageManager pm=getPackageManager();
try {
PackageInfo info=pm.getPackageInfo(targetPackage,PackageManager.GET_META_DATA);
} catch (PackageManager.NameNotFoundException e) {
return false;
}
return true;
}
Without using a try-catch block or iterating through a bunch of packages:
public static boolean isPackageInstalled(Context context, String packageName) {
final PackageManager packageManager = context.getPackageManager();
Intent intent = packageManager.getLaunchIntentForPackage(packageName);
if (intent == null) {
return false;
}
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
Kotlin
fun isPackageExist(context: Context, target: String): Boolean {
return context.packageManager.getInstalledApplications(0).find { info -> info.packageName == target } != null
}
Edit: Extension Function
fun Context.isPackageExist(target: String): Boolean {
return packageManager.getInstalledApplications(0).find { info -> info.packageName == target } != null
}
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
PackageManager packageManager = getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
boolean isIntentSafe = activities.size() > 0;
We can check like this:
if(getPackageManager().hasSystemFeature("android.software.webview") == true && isPackageExisted("com.google.android.webview")) {
if (Constant.isNetworkConnected(Activity.this)) {
//Your Intent
} else {
Toast.makeText(getApplicationContext(), resources.getString(R.string.internet_error), Toast.LENGTH_SHORT).show();
}
} else
{
Constant.showDialog(Activity.this,"Please install the webview");
}
}
Make method for package check ! this credit goes to "Kavi" https://stackoverflow.com/a/30708227/6209105
public boolean isPackageExisted(String targetPackage) {
List<ApplicationInfo> packages;
PackageManager pm;
pm = getPackageManager();
packages = pm.getInstalledApplications(0);
for (ApplicationInfo packageInfo : packages) {
if(packageInfo.packageName.equals(targetPackage))
{
return true;
}
}
return false;
}
You should use PackageManager's function called getInstalledPackages() to get the list of all installed packages and the search for the one you are interested in. Note that package name is located in PackageInfo.packageName field.
Since some devices have reported that the "getInstalledPackages" can cause TransactionTooLargeException (check here, here and here), I think you should also have a fallback like I did below.
This issue was supposed to be fixed on Android 5.1 (read here), but some still reported about it.
public static List<String> getInstalledPackages(final Context context) {
List<String> result = new ArrayList<>();
final PackageManager pm = context.getPackageManager();
try {
List<PackageInfo> apps = pm.getInstalledPackages(0);
for (PackageInfo packageInfo : apps)
result.add(packageInfo.packageName);
return result;
} catch (Exception ignored) {
//we don't care why it didn't succeed. We'll do it using an alternative way instead
}
// use fallback:
BufferedReader bufferedReader = null;
try {
Process process = Runtime.getRuntime().exec("pm list packages");
bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while ((line = bufferedReader.readLine()) != null) {
final String packageName = line.substring(line.indexOf(':') + 1);
result.add(packageName);
}
closeQuietly(bufferedReader);
process.waitFor();
} catch (Exception e) {
e.printStackTrace();
} finally {
closeQuietly(bufferedReader);
}
return result;
}
public static void closeQuietly(final Closeable closeable) {
if (closeable == null)
return;
try {
closeable.close();
} catch (final IOException e) {
}
}
If you just want to use adb:
adb shell "pm list packages"|cut -f 2 -d ":"
it will list all installed packages.
You can use pm.getPackageUid() instead of iterating over the pm.getInstalledApplications()
boolean isPackageInstalled;
PackageManager pm = getPackageManager();
int flags = 0;
try
{
pm.getPackageUid(packageName,flags);
isPackageInstalled = true;
}
catch (final PackageManager.NameNotFoundException nnfe)
{
isPackageInstalled = false;
}
return isPackageInstalled;
According to the Package visibility filtering changes in Android 11, you need to add this permission to your manifest to be able to list installed apps:
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>
but Google doesn't recommend to use this way. You should use <queries> tag instead:
<manifest ...>
<queries>
<package android:name="com.app.package" />
...
</queries>
...
</manifest>
And in your code:
fun isAppInstalled(context: Context, packageId: String): Boolean {
return try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
context.packageManager
.getApplicationInfo(packageId, PackageManager.ApplicationInfoFlags.of(0))
} else {
context.packageManager.getApplicationInfo(packageId, 0)
}
true
} catch (e: PackageManager.NameNotFoundException) {
false
}
}
