Hi friends, Have a great day. I comeback after long time. Ok,  now will look up to show password option in edit text. Now most of login screens comes up with another cool feature, that's show password. User want to see their password, until they done editing. You can use it with checkbox option. It's simple, but you can make it by your way. @Override     public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {         if(!isChecked){             edit_password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());         }else{             edit_password.setTransformationMethod(PasswordTransformationMethod.getInstance());         }     }

Few days before I created one app, It's a map application. It's not a great application, but simple application. To load the data from the web, data has too be listed, when you select or click particular user data, load the map with marker. I tried with my knowledge, but don't expect too much. But it will be useful for beginners and peoples who are trying the map at first time. Get from the my GITHUB

It's Interesting, most of peoples thinks about the database, shared preferences and content providers for offline data storage. Some different came like data must be stored in cache, when app offline, retrieve data from the cache. Just try this, It might be useful for you. public String temp_filename = "user_data.txt"; public File tempFile; // To Store the file in Cache public void storeToCache(Context context, String data) {         if (data != null && !data.equals("")) {             FileWriter writer;             try {                 writer = new FileWriter(getCacheFile(context));                 writer.write(data);                 writer.close();                 Log.d(TAG, "stored to cache");         ...

Have a great day friends. Today will look up validating the URL. How to do this? Most of times, your internet will be working, but sometimes URL to be busy or invalid. In this case, we follow this thing.  public boolean isServerReachable(Context context, String url) {         ConnectivityManager connMan = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);         NetworkInfo netInfo = connMan.getActiveNetworkInfo();         if (netInfo != null && netInfo.isConnected()) {             try {                 URL urlServer = new URL(url);                 if(url.startsWith("https")){                     HttpsURLConnection urlConn = (HttpsURLConnection) urlServer.openConnection();              ...

Previous post I explain about the sharing the data using broadcast. This post about to share the data using the intents. By using Intent In First Application Intent intent = new Intent(); intent.setClassName("com.sample.app", "com.sample.app.MainActivity"); intent.putExtra("EXTRA_ORDERID", "#4FGT784"); intent.putExtra("EXTRA_ORDERNOTES", "No warranty for this product"); intent.putExtra("EXTRA_ORDERAMOUNT", "270"); PackageManager packageManager = getPackageManager(); List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0); boolean isIntentSafe = activities.size() > 0; if (isIntentSafe) { startActivity(intent); } else { Toast.makeText(MainActivity.this, "Application not installed", Toast.LENGTH_LONG).show(); } In Second Application Bundle vals = getIntent().getExtras(); if (vals != null) { String orderId = vals.getS...

Hi Friends, Have a great day. It's my 75th blog. I'm very slow, but I'm post only necessary and important posts only, hope so. This time we'll look some manual broadcast message sending from another application, best way to for testing the notifications. By Using send broadcast. In First Application ComponentName componentName = new ComponentName("com.sample.app", "com.sample.app.receiver.NotificationReceiver"); Intent intent = new Intent(); intent.setComponent(componentName); String message = "Order ID:  #AER46798 "; intent.putExtra("EXTRA_TITLE", "New Order Received"); intent.putExtra("EXTRA_MESSAGE", message); sendBroadcast(intent); In Second Application Receiver public class NotificationReceiver extends BroadcastReceiver {     public static String TAG = "PCM";     @Override     public void onReceive(Context context, Intent intent) {         Log.i(TAG, "message_received"); ...

In Java usually validate with some specific characters, we should use Regular Expressions. Same way in Android, here we use Patterns. More info about the Patterns: Click here In android EditText, we can use custom input filter to perform this. This is for maximum input digits before and after decimal pointer. CustomInputFilter.Java public class CustomInputFilter implements InputFilter {     int maxDigitsBeforeDecimalPoint;     int maxDigitsAfterDecimalPoint;     public CustomInputFilter(int maxDigitsBeforeDecimalPoint, int maxDigitsAfterDecimalPoint) {         this.maxDigitsBeforeDecimalPoint = maxDigitsBeforeDecimalPoint;         this.maxDigitsAfterDecimalPoint = maxDigitsAfterDecimalPoint;     }     @Override     public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {         StringBuilder builder =...

To enable back button should be not close the application and web pages navigation only,     @Override     public boolean onKeyDown(int keyCode, KeyEvent event) {         if (keyCode == KeyEvent.KEYCODE_BACK) {                webview.goBack();             return true;         }         return super.onKeyDown(keyCode, event);     } Webview settings:         WebSettings webSetting = sWebview.getSettings();         webSetting.setJavaScriptEnabled(true);         webSetting.setDisplayZoomControls(false);         //Set whether the DOM storage API is enabled.         webSetting.setDomStorageEnabled(true);         sWebview.setWebChromeClient(new WebChromeClient());         sWebv...

Have a great day. Set the permission in Manifest.xml <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.INTERNET" /> Then just use below code:  public String getLocalIpAddress() {         String firstIP = "192.168.0.1";         ArrayList<String> ipList = new ArrayList<String>();         try {             for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {                 NetworkInterface intf = en.nextElement();                 for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {                     InetAddress inetAddress = enumIpAddr.nex...

Now three... Hope this will be very useful for those who doing time intervals and web services. ServiceChecker.Java  import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class ServiceChecker extends BroadcastReceiver {     ShukranDbHelper dbHelper;     @Override     public void onReceive(Context context, Intent arg1) {         // Just calling your method Log.d("hey", "I'm alive");     } } In AndroidManifest.xml <receiver android:name=".service.DataChecker"></receiver> In your Activity, Just call this. Intent alarmIntent = new Intent(this, ServiceChecker.class); pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0); startAlarm(); public void startAlarm() {     manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);     int interval =600000; // 10 minute //10000     ...

Hello friends, Hope you already see this example in lot of websites and blogs. I'm also doing these, because hope my example might be easy and understandable. Let's go. Create the class: ConnectivityReceiver.Java public class ConnectivityReceiver extends BroadcastReceiver {     public static ConnectivityReceiverListener connectivityReceiverListener;     public ConnectivityReceiver() {         super();     }     @Override     public void onReceive(Context context, Intent arg1) {         ConnectivityManager cm = (ConnectivityManager) context                 .getSystemService(Context.CONNECTIVITY_SERVICE);         NetworkInfo activeNetwork = cm.getActiveNetworkInfo();         boolean isConnected = activeNetwork != null                 && activeNetwork.isConn...

Hi friends, Have a great day. Today we're going to look for touch events in fragment. Taps - If you gonna multiple tap to view or do something, this will be more helpful. Just implement TouchListener in your fragment like this, public class FirstFragment extends Fragment implements View.OnTouchListener Then     @Override     public boolean onTouch(View v, MotionEvent event) {         int eventaction = event.getAction();         if (eventaction == MotionEvent.ACTION_UP) {             //get system current milliseconds             long time = System.currentTimeMillis();             //if it is the first time, or if it has been more than 3 seconds since the first tap ( so it is like a new try), we reset everything             if (startMillis == 0 || (time - startMillis > 3000)) {     ...

Hi Everyone, Have a great day. Happy Feb. How to add app name, version name in the generated apk?  - It's very interesting question asked by my junior developer. In app.gradle Under the android just add following line: project.archivesBaseName = "IndAppz"; more? add the version information: Put the following code under the buildTypes. applicationVariants.all { variant ->                 variant.outputs.each{ output ->                     output.outputFile = new File(output.outputFile.parent,output.outputFile.name.replace(".apk","-" + defaultConfig.versionName+".apk" ))                 }             } even more? add the app with date information: define the date: def getDate() {     new Date().format('ddMMMyyyy') } And then add the date info into the file name. applicationVariants.all...
