Implementing the AePS Service App

On click operation

binding.submitButton.setOnClickListener(view -> checkAppInstalledOrNot());

Checking that the application already installed or not

private void checkAppInstalledOrNot() { boolean installed = appInstalledOrNot("com.aeps.aeps_api_user_sandbox"); try { if (installed) { sendDataToService("com.aeps.aeps_api_user_sandbox"); } else { /It will be displayed if the app is not installed on your phone/ showAlert(); } } catch (Exception e) { e.printStackTrace(); } }

Checking that the application installed or not

private boolean appInstalledOrNot(String uri) { PackageManager pm = getPackageManager(); try { pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES); return true; } catch (PackageManager.NameNotFoundException e) { } return false; }

Alert showing when the service app is not installed on phone

public void showAlert() { try { AlertDialog.Builder alertbuilderupdate; alertbuilderupdate = new AlertDialog.Builder(this, android.R.style.Theme_Material_Light_Dialog_Alert); alertbuilderupdate.setCancelable(false); String message = "Please download the AEPS SERVICE app ."; alertbuilderupdate.setTitle("Alert") .setMessage(message) .setPositiveButton("Download Now", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { redirectToAppStore(); } }) .setNegativeButton("Not Now", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); AlertDialog alert11 = alertbuilderupdate.create(); alert11.show(); } catch (Exception e) { e.printStackTrace(); } }

If not installed then redirect to app store

public void redirectToAppStore() { Uri uri = Uri.parse("https://liveappstore.in/shareapp?com.aeps.aeps_api_user_sandbox=") Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_NEW_DOCUMENT | Intent.FLAG_ACTIVITY_MULTIPLE_TASK); try { startActivity(goToMarket); } catch (ActivityNotFoundException e) { try { startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://liveappstore.in/shareapp?com.aeps.aeps_api_user_sandbox=") } catch (Exception exception) { Toast.makeText(this, "App Not Found", Toast.LENGTH_SHORT).show(); } } }
