Check if your Android app is in foreground or background


Now I have my Own Blog. Follow Link to learn more about Android Development.


In this example I will explain how to check if your Android Application is running in foreground or it is in background.

Note: we do not need to add any permission for this code. we will be using ActivityManager class
and its method getRunningAppProcesses()
getRunningAppProcesses() Returns a list of application processes that are running on the device.

Also I am using AsyncTask because we should not call ActivityManager.getRunningAppProcesses()
from UI thread it will return importance IMPORTANCE_FOREGROUND for your task no matter whether it is actually in the foreground or not.


 private class CheckIfForeground extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... voids) {

        ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
        for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
            if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                Log.i("Foreground App", appProcess.processName);

                if (mContext.getPackageName().equalsIgnoreCase(appProcess.processName)) {
                    Log.i(Constants.TAG, "foreground true:" + appProcess.processName);
                    foreground = true;
                    // close_app();
                }
            }
        }
        Log.d(Constants.TAG, "foreground value:" + foreground);
        if (foreground) {
            foreground = false;
            close_app();
            Log.i(Constants.TAG, "Close App and start Login Activity:");

        } else {
            //if not foreground
            close_app();
            foreground = false;
            Log.i(Constants.TAG, "Close App");

        }

        return null;
    }
}
and execute AsyncTask like this.
new CheckIfForeground().execute();
Please Note this code is tested on Android Version 5.0.2

android-material-design-small-rating-bar


Hello Guys, Now I have my own Blog Site. please visit Link for more Android and Kotlin Tutorials.







In this example I will teach you how to add Material Design and smaller Rating Bar in your Android Application.
Resulting smaller and material design rating bar can be seen in attached image.

Add this in your layout XML file.


                    <RatingBar
                    style="@style/RatingBar"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:numStars="5"
                    android:rating="3.5"
                    android:stepSize="0.5" />

Open styles.xml file and add below code in styles file for styling rating bar.
Basic idea is to set parent to material rating bar to smaller.

<style name="RatingBar"   
parent="android:style/Widget.Material.RatingBar.Small">
<item name="colorControlNormal">@color/primary_light</item>
<item name="colorControlActivated">@color/primary_dark</item>
</style>


This style can only be used as indicator. it do not support user interaction. If you need to support user interaction use Default Rating Bar. i.e 

"Base.Widget.AppCompat.RatingBar" as parent. Also num of stars property only works with
 width wrap content when working with default Rating Bar.

You can customise rating bar to make it look like standard yellow rating bar using below
properties in xml.



android:progressBackgroundTint="@color/primary_light"
android:progressTint="@color/rating_star"
android:secondaryProgressTint="@color/primary_light"



"progressTint" is rating color (yellow)"progressBackgroundTint" is default color (when no rating)
"secondaryProgressTint" is remaining color of partially filled rating star.


Note: Application theme is AppCompat and donot forget to add appcompat support dependency 
in build.gradle file.
