I am working with payment using net banking and doing payment from web chrome now when i back to the activity i want to check that payment is done or cancelled... how to check this in my activity when i came back from web in my android application project?
You can use applinks.
When you have done with payment your backend redirects to custom urls and you can listen them with intent-filters.
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
<data
android:path="/PaymentCancelled"
android:host="yourhost.com"
android:scheme="https" />
<data
android:path="/PaymentDone"
android:host="yourhost.com"
android:scheme="https" />
</intent-filter>
