Summary

• Internal name: IsAppInstalled
• Category: Package Manager
• Purpose: Check whether an application is installed on the device. Branches the workflow: true if the package exists, false otherwise.
• Task type: Condition

---

Compatibility

• Minimum AndroMate version: 1.1.0

• Maximum AndroMate version: 1.1.0

• Minimum Android: Android 13 (API 33)

• Maximum Android tested: Android 16 (API 36)

• Required permissions: QUERY_ALL_PACKAGES

---

Detailed description

The Is App Installed task checks the presence of a package on the device using the Android PackageManager. It acts as a condition node: the workflow branches to the true path if the package is installed, and to the false path otherwise.

Since Android 11 (API 30), apps cannot see other installed packages by default (package visibility filtering). AndroMate declares the QUERY_ALL_PACKAGES permission so it can detect any installed package by name.

This task never throws — a missing package simply routes to the false branch.

Input parameters

Parameter	Type	Required	Possible values / Rules	Android Compatibility	AndroMate Compatibility	Default
package_name	String	Yes	Valid Android package name (com.example.app)	Android 13 (API 33) → Android 16 (API 36)	1.1.0 → 1.1.0	""

---

Output parameters

This is a Condition task — it does not store a value. Instead, it directs workflow execution:

Condition	Next step
Package is installed	true branch
Package is not installed	false branch

---

Exceptions

This task does not throw exceptions. A missing package routes to the false branch.

Execution flowchart

    Start([▶ IsAppInstalled]) --> Resolve[🔧 Resolve package_name]

    Resolve --> Query[📦 PackageManager.getPackageInfo]

    Query --> Installed{Package installed ?}

    Installed -->|Yes| TrueBranch([✅ true branch])
    Installed -->|No| FalseBranch([❌ false branch])

    style Start fill:#e3f2fd
    style TrueBranch fill:#c8e6c9
    style FalseBranch fill:#ffcdd2
    style Query fill:#fff9c4

How it works:

1. Resolve: the package_name is resolved against the AndroMate context
2. Query: PackageManager.getPackageInfo() is called
3. Branch: if the call succeeds → true branch; if it throws NameNotFoundException → false branch

Code examples

Example 1 — Branch on WhatsApp presence

{
  "IsAppInstalled": [
    {
      "id": "1",
      "title": "WhatsApp installed ?",
      "package_name": "com.whatsapp"
    }
  ]
}

Input parameter details

package_name — Target package

The Android package identifier to check for.

• Must be a valid package name (e.g. com.whatsapp)
• Supports variable interpolation (e.g. $target_pkg, ${PKG})
• The package does not need to be installed — that is exactly what this task tests

---

Output parameter details

This is a Condition task — it stores no output variable. The result drives the workflow branching:

true branch

Taken when PackageManager.getPackageInfo() succeeds (the package is installed).

false branch

Taken when the package is absent (NameNotFoundException).
