How You Can Keep Your Android Apps Always On High Response Mode?

Keep your apps highly responsive

It’s very much feasible for Android developers to write code on Android to make the system work much faster to win the performance test from any other operating devices in the world. But still I think its often sluggish to work with high performance systems every-time that can hang or it might freeze for a significant amount of time to process every input. Which is the worst thing that can happen to your Android app’s while you are accessing it: it will alert you with the following message “Application Not Responding” or ANR dialog box.

I will introduce you guys with “What Triggers ANR” process?

All things considered, it happens that the framework shows an ANR message just on the off chance that your application is not in the slightest degree reacting for your asked message.

For instance, if there is an application that tends to hinders some of your I/O operations on UI strings that in the end will limit your framework to react to any approaching client info occasions. On the other side, it additionally may be the situation if your application is investing a lot of energy to create and expand in-memory structure, and figuring the following procedure in an amusement on your UI string. At that point, it’s basic to contemplate that such calculations are productive, yet at the same time it requires a huge investment to run the procedure.

Android-apps

In Android, application responsiveness has proficiently observed the procedure known as “Action Manager and Window Manager” framework administrations. Android then shows the ANR dialog box for a specific application process when it identifies one of the accompanying conditions as and when required:

  • No reaction to an information requested within 5 seconds.
  • A Broadcast Receiver still has not wrapped up the undertaking inside of 10 seconds.

You will come across millions of Android app development companies who can handle such serious issues that occurs while installing or working with Android applications. But this is not the last thing that you should look for. Find Android app development companies who offers knack of dealing with such serious issues that often occurs when you start working with apps with fantastic solutions to avoid future glitches. Prefer to work with Android app development companies who offers great advantage of developing high -quality Android applications and can simultaneously solve ANR errors side-by-side.

Steps you should prefer to avoid ANR error in Android systems

On the off chance that you are an Android client, then you may know about Android applications that regularly likes to run altogether on a solitary accessing so as to string the default “UI string” or you can say “fundamental string”. That particularly implies that application is executing its undertaking in UI string that ordinarily takes quite a while to finish any procedure in your Android triggering so as to work gadgets the message ANR dialog in light of the fact that your application is not in the slightest degree in a state to get the data occasions.

So, any method that will efficiently execute the process in the UI thread should perform the task carefully. Activities should perform every task carefully in order to set up in key life-cycle methods such as onCreate() and onResume()methods.

One of the most effective way to avoid such error is to build a worker thread to easily handle longer operations: AsyncTask class. User can easily extend AsyncTask and implement it with doInBackground() method. To post progress the changes to the user, user can easily follow a process to call publishProgress(), that will invoke the onProgressUpdate() callback method.

For example:

private class DownloadImage extends AsyncTask<URL, Integer, String> {

// Do the long-running work in here
protected String doInBackground(URL… urls) {
String savedImagePath = “/sdcard/image.jpg”;
int count;
try {
URL url = urls[0];
URLConnection connection = url.openConnection();
connection.connect();
InputStream input = new BufferedInputStream(url.openStream(), 2048);
OutputStream output = new FileOutputStream(savedImagePath);
int lenghtOfFile = connection.getContentLength();
byte data[] = new byte[2048];
long total = 0;

while ((count = input.read(data)) != -1) {
total += count;
output.write(data, 0, count);

// publishing progress..
publishProgress((int) ((total * 100) / lenghtOfFile));
}

output.flush();
output.close();
input.close();
return savedImagePath;
} catch (Exception e) {
Log.e(“Error: “, e.getMessage());
}

return null;
}
// This is triggered when publishProgress() is called to notify progress in UI thread
protected void onProgressUpdate(Integer… progress) {
updateProgress(progress[0]);
}
// This is triggered when doInBackground() is finished
protected void onPostExecute(String imagePath) {
displayImage(imagePath);
}
}
// To execute this worker thread, simply create an instance and call execute():
new DownloadImage().execute(imageUrl);

How to Strengthen your System Responsiveness

  • If your application is performing well in the background mode on user input, then it shows that progress is being made with a ProgressBar in your UI.

  • For games specifically, performing calculations for moves in a worker thread will be of great help.

  • If any of your application takes a huge amount of time in its initial setup phase, then it indicate that loading process is in progress and will fill-up all the information simultaneously. It further indicates that application status is in progress status.

  • Use performance tools such as Systrace and Traceview to determine deadlock situation in your app’s responsiveness.
