问题
I'm developing an android app. Some data is getting retrieved from the FirebaseDatabase and is getting shown in a RecyclerView in my app.
The RecyclerView has cards in it. In every card, the images and text is shown. On the card there is a 'share' button, by clicking on which a dynamic-link is generated and is getting shared with anybody. When I click on the shared dynamic-link, the app gets open and what happens is that the image which was on the same card the share button was clicked is getting displayed, but the text is always getting displayed of the last saved data. I hope you got my point.
Here's how I'm generating dynamic-link:
Button btnShare = (Button) holder.itemView.findViewById(R.id.btn_share);
btnShare.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Uri BASE_URL = Uri.parse("http://www.appwebsite.com/");
holder.APP_URI = BASE_URL.buildUpon().path(imageUIDh).build();
packageName = holder.itemView.getContext().getPackageName();
deepLinkTS = Uri.parse("https://u9p25.app.goo.gl/?link="+holder.APP_URI+"&apn="+packageName+"&amv="+16+"&ad="+0);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Please help this needy: " + deepLinkTS.toString() + "\n-shared through app.");
holder.itemView.getContext().startActivity(Intent.createChooser(intent, "Share via..."));
}
});
Here's how I'm handling dynamic-link in onCreate() method of MainActivity.class:
boolean autoLaunchDeepLink = false;
AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, MainActivity.this, autoLaunchDeepLink)
.setResultCallback(
new ResultCallback<AppInviteInvitationResult>() {
@Override
public void onResult(@NonNull AppInviteInvitationResult result) {
if (result.getStatus().isSuccess()) {
// Extract deep link from Intent
Intent intent = result.getInvitationIntent();
final String deepLink = AppInviteReferral.getDeepLink(intent);
// Handle the deep link. For example, open the linked
// content, or apply promotional credit to the user's
// account.
final ProgressDialog openingSharedRequest = new ProgressDialog(MainActivity.this);
openingSharedRequest.setMessage("Opening shared help-request...");
openingSharedRequest.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
Intent helpRequestIntent = new Intent(MainActivity.this, HelpRequestThroughDeepLink.class);
helpRequestIntent.putExtra("deepLink", deepLink);
// helpRequestIntent.putExtra("deepLinkTS", HelpRequest.deepLinkTS.toString());
// helpRequestIntent.putExtra("APP_URI", HelpRequest.ViewHolder.APP_URI.toString());
helpRequestIntent.putExtra("postedFrom", postedFromS);
// new AlertDialog.Builder(MainActivity.this)
// .setMessage(deepLink)
// .setPositiveButton("OK", null)
// .create()
// .show();
startActivity(helpRequestIntent);
openingSharedRequest.dismiss();
}
}, 1200);
// [START_EXCLUDE]
// Display deep link in the UI
// ((TextView) findViewById(R.id.link_view_receive)).setText(deepLink);
// [END_EXCLUDE]
} else {
// Log.d(TAG, "getInvitation: no deep link found.");
// Toast.makeText(getBaseContext(), "Some error occurred", Toast.LENGTH_SHORT).show();
}
}
});
// [END get_deep_link]
Here's code from HelpRequestThroughDeepLink.java:
public class HelpRequestThroughDeepLink extends AppCompatActivity {

}
private void doSomethingWithPicaso(String imageUIDh, ImageView target){

}
});
}
private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager
= (ConnectivityManager) HelpRequestThroughDeepLink.this.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

Please let me know how can I achieve this?
