Check if application is installed - Android

AndroidAndroid IntentGoogle Play

Android Problem Overview

I'm trying to install apps from Google Play. I can understand that on opening the Google Play store URL, it opens the Google Play and when I press the back button, the activity resumes.

Intent marketIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(appURL));
marketIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(marketIntent);

When I went back to the activity, I tried calling this onResume() to check if the app is installed, but I receive an error:

@Override
protected void onResume() {
    super.onResume();
    boolean installed = false;
    while (!installed) {
        installed  =   appInstalledOrNot(APPPACKAGE);
        if (installed) {
             Toast.makeText(this, "App installed", Toast.LENGTH_SHORT).show();
        }
    }
}

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 ;
}

The error is as follows:

> E/AndroidRuntime(796): java.lang.RuntimeException: Unable to start > activity > ComponentInfo{com.example.appinstaller/com.example.appinstaller.MainActivity}: > android.content.ActivityNotFoundException: > No Activity found to handle Intent { act=android.intent.action.VIEW > dat=market://details?id=com.package.name flg=0x40080000 }

I guess the activity is onPause(). Is there a better way to implement it? I'm trying to check if the app has finished installing.

Solution 1 - Android

Try this:

private boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        packageManager.getPackageInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

It attempts to fetch information about the package whose name you passed in. Failing that, if a NameNotFoundException was thrown, it means that no package with that name is installed, so we return false.

Note that we pass in a PackageManager instead of a Context, so that the method is slightly more flexibly usable and doesn't violate the law of Demeter. You can use the method without access to a Context instance, as long as you have a PackageManager instance.

Use it like this:

public void someMethod() {
    // ...
    
    PackageManager pm = context.getPackageManager();
    boolean isInstalled = isPackageInstalled("com.somepackage.name", pm);
    
    // ...
}

Note: From Android 11 (API 30), you might need to declare <queries> in your manifest, depending on what package you're looking for. Check out the docs for more info.

Solution 2 - Android

Since Android 11 (API level 30), most user-installed apps are not visible by default. In your manifest, you must statically declare which apps you are going to get info about, as in the following:

<manifest>
    <queries>
        <!-- Explicit apps you know in advance about: -->
        <package android:name="com.example.this.app"/>
        <package android:name="com.example.this.other.app"/>
    </queries>
    
    ...
</manifest>

Then, @RobinKanters' answer works:

private boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        packageManager.getPackageInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

// ...
// This will return true on Android 11 if the app is installed,
// since we declared it above in the manifest.
isPackageInstalled("com.example.this.app", pm); 
// This will return false on Android 11 even if the app is installed:
isPackageInstalled("another.random.app", pm);

Solution 3 - Android

Robin Kanters' answer is right, but it does check for installed apps regardless of their enabled or disabled state.

We all know an app can be installed but disabled by the user, therefore unusable.

This checks for installed AND enabled apps:

public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        return packageManager.getApplicationInfo(packageName, 0).enabled;
    }
    catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

You can put this method in a class like Utils and call it everywhere using:

boolean isInstalled = Utils.isPackageInstalled("com.package.name", context.getPackageManager())

Solution 4 - Android

Faster solution:

private boolean isPackageInstalled(String packagename, PackageManager packageManager) {
    try {
        packageManager.getPackageGids(packagename);
        return true;
    } catch (NameNotFoundException e) {
        return false;
    }
}

getPackageGids is less expensive from getPackageInfo, so it work faster.

Run 10000 on API 15
Exists pkg:
getPackageInfo: nanoTime = 930000000
getPackageGids: nanoTime = 350000000
Not exists pkg:
getPackageInfo: nanoTime = 420000000
getPackageGids: nanoTime = 380000000

Run 10000 on API 17
Exists pkg:
getPackageInfo: nanoTime = 2942745517
getPackageGids: nanoTime = 2443716170
Not exists pkg:
getPackageInfo: nanoTime = 2467565849
getPackageGids: nanoTime = 2479833890

Run 10000 on API 22
Exists pkg:
getPackageInfo: nanoTime = 4596551615
getPackageGids: nanoTime = 1864970154
Not exists pkg:
getPackageInfo: nanoTime = 3830033616
getPackageGids: nanoTime = 3789230769

Run 10000 on API 25
Exists pkg:
getPackageInfo: nanoTime = 3436647394
getPackageGids: nanoTime = 2876970397
Not exists pkg:
getPackageInfo: nanoTime = 3252946114
getPackageGids: nanoTime = 3117544269

Note: This will not work in some virtual spaces. They can violate the Android API and always return an array, even if there is no application with that package name.
In this case, use getPackageInfo.

Solution 5 - Android

Try this:

public static boolean isAvailable(Context ctx, Intent intent) {
    final PackageManager mgr = ctx.getPackageManager();
    List<ResolveInfo> list =
        mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

Solution 6 - Android

You can use this in Kotlin extentions.kt

fun Context.isPackageInstalled(packageName: String): Boolean {
    return try {
        packageManager.getPackageInfo(packageName, 0)
        true
    } catch (e: PackageManager.NameNotFoundException) {
        false
    }
}

Usage

context.isPackageInstalled("com.somepackage.name")

Solution 7 - Android

If you want to try it without the try catch block, can use the following method, Create a intent and set the package of the app which you want to verify

val intent = Intent(Intent.ACTION_VIEW)
intent.data = uri
intent.setPackage("com.example.packageofapp")

and the call the following method to check if the app is installed

fun isInstalled(intent:Intent) :Boolean{
    val list = context.packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
    return list.isNotEmpty()
}

Those who are looking for Kotlin solution can use this method,

Here I have shared full code, and also handled enabled status. Check If Application is Installed in Android Kotlin

fun isAppInstalled(packageName: String, context: Context): Boolean {
        return try {
            val packageManager = context.packageManager
            packageManager.getPackageInfo(packageName, 0)
            true
        } catch (e: PackageManager.NameNotFoundException) {
            false
        }
    }

Solution 9 - Android

After Android 11 you need to add package names in <queries> in the Manifest of Application.

if you don't <queries> in the Manifest, always context.getPackageManager().getApplicationInfo has an exception (System.err: android.content.pm.PackageManager$NameNotFoundException)

check the reference:link

Example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <queries>
        <package android:name="com.xxx.yyy" />
    </queries>

    <application></application>

</manifest>

Java

 public boolean applicationIsInstall(Context context , String packageName){
        try {
            context.getPackageManager().getApplicationInfo(packageName, 0);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
            return false;
        }
    }

fun applicationIsInstall(context: Context, packageName: String): Boolean {
    return try {
        context.packageManager.getApplicationInfo(packageName, 0)
        true
    } catch (e: PackageManager.NameNotFoundException) {
        e.printStackTrace()
        false
    }
}

Solution 10 - Android

    private boolean isAppExist() {

    PackageManager pm = getPackageManager();
    try {
        PackageInfo info = pm.getPackageInfo("com.facebook.katana", PackageManager.GET_META_DATA);
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
    return true;
}




if (isFacebookExist()) {showToast(" Facebook is  install.");}
     else {showToast(" Facebook is not install.");}

Solution 11 - Android

isFakeGPSInstalled = Utils.isPackageInstalled(Utils.PACKAGE_ID_FAKE_GPS, this.getPackageManager());

//method to check package installed true/false

  public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    boolean found = true;
    try {
      packageManager.getPackageInfo(packageName, 0);
    } catch (PackageManager.NameNotFoundException e) {
      found = false;
    }

    return found;
  }
