If your Android app is offline and doesn't have a backend, you can still use Google Play Integrity API to check whether the app is installed from the Play Store and running on a genuine device. However, since there's no server to verify the integrity token, you will only be able to check basic integrity locally. ✅ Steps to Use Play Integrity API Without a Backend (Offline Mode) 1️⃣ Enable Play Integrity API in Google Play Console Go to Google Play Console . Select your app → Navigate to Setup → App Integrity . Enable the Play Integrity API . Save the License Key (you won’t need it for offline checks, but it's useful for future reference). 2️⃣ Add Dependencies In your app-level build.gradle , add the Play Integrity dependency: dependencies { implementation 'com.google.android.play:integrity:1.3.0' } Sync the project after adding the dependency. 3️⃣ Implement Play Integrity API Locally in Android App Since you don’t have a backend, you can directly verify the...

 In Android 15 (API level 34) , the SEND_SMS permission is restricted for most apps. This change is part of Google's security enhancements to prevent misuse and protect user privacy. 🔎 Why You See This Error Restricted Permissions : Starting from Android 15, only default SMS apps or apps granted special carrier privileges can request the SEND_SMS permission. Non-Default Apps : If your app is not the system's default SMS app, it cannot send SMS using the SmsManager or Intent.ACTION_SENDTO . ✅ Solutions and Workarounds Here are a few options depending on your app's needs: 1. Check if Your App is the Default SMS App If your app is a messaging app, request users to set it as the default SMS app using this intent: Intent intent = new Intent (Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT); intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, getPackageName()); startActivity(intent); 2. Use SMS Verification API (For OTPs) If you're sending S...

 Here’s a simple approach to find and remove unused dependencies in your Ionic 3 & Angular 5 app: Steps to Remove Unused Dependencies 1. Identify Unused Dependencies Use the depcheck tool to check which dependencies are unused. Install depcheck globally npm install -g depcheck Run depcheck in your project root depcheck It will list: Unused dependencies (can be removed) Missing dependencies (need to be installed) 2. Remove Unused Dependencies Once identified, uninstall them: npm uninstall package-name Or remove multiple at once: npm uninstall package1 package2 package3 3. Check Cordova Plugins Run: cordova plugin list Manually remove unnecessary plugins: cordova plugin remove plugin-name 4. Clean node_modules and Reinstall rm -rf node_modules package-lock.json npm install 5. Optimize Your Build Run: npm run build --prod to ensure performance improvements.

 The best approach between <FrameLayout> and <androidx.fragment.app.FragmentContainerView> for showing fragments in Android development depends on your project requirements. Here's a detailed comparison: 1. FrameLayout (Older Approach) ✅ Pros: Works well for dynamically adding and replacing fragments. Simple to use and has been widely used in older Android versions. ❌ Cons: Doesn't provide built-in fragment animations. Might cause issues with fragment state restoration. Less optimized for modern fragment transactions. Example Using FrameLayout xml < FrameLayout android:id = "@+id/fragmentContainer" android:layout_width = "match_parent" android:layout_height = "match_parent" /> kotlin supportFragmentManager.beginTransaction() .replace(R.id.fragmentContainer, HomeFragment()) .commit() 2. FragmentContainerView (Recommended) ✅ Pros: Officially recommended by Android Jetpack for better fragment management. S...
