This is a smali code which returns a Title and a Link from 'weblink' inside a database file. I want to return a static value (example 'This is the link www.google.com ' ) instead of Title and Link from database file. How can I do that? What code should I change? This is similar to this question here ( How to return a static result in smali function ) and I already tried that solution. But app is force closing. can somebody help?

Install https://github.com/ollide/intellij-java2smali and create a java class with a method that returns what you want. Convert it to smali and learn from it — Pedro Oliveira, Apr 13 '16 at 06:02
solved it by half. I was able to change link to title and add my own text to const-string v4 . Now link is gone from shareable text but title is added twice. I tried to remove both title and link and show only value in the const-string v4 . But when I do it, app is force closing...Any idea? — user3548321, Apr 13 '16 at 11:28
Use a debugger (DDMS) to log the exception. We can't help you without it. — Luca D'Amico, Apr 13 '16 at 17:21
I tried intellij java2smali but i'm facing problem. When I click "compile to smali", nothing is happening.. There's no smali code.. It shows "cleaning output directors finished, saving... " But no smali file is generated. I don't know what's wrong. Using intellijidea 2016.1.1 — user3548321, Apr 18 '16 at 02:05

Simply override the content of the string object before it's appended to the StringBuilder.

.line 304
invoke-virtual {v0}, Lcom/myapp/data/weblink;->getTitle()Ljava/lang/String;

move-result-object v4

# Add following line to override v4 before it's appended to the StringBuilder
const-string v4, "This is the link"

invoke-virtual {v3, v4}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;

Similarly, you can do the same for the link

invoke-virtual {v0}, Lcom/myapp/data/weblink;->getLink()Ljava/lang/String;

move-result-object v0

invoke-virtual {v0}, Ljava/lang/String;->toString()Ljava/lang/String;

move-result-object v0

# Add following line to override v0 before it's appended to the StringBuilder
const-string v0, "www.google.com"

invoke-virtual {v3, v0}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;

Actually, you can override the whole string at once before it's put to the intent.

invoke-virtual {v0}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;

move-result-object v0

# Add this line
const-string v0, "The whole text you want, including the title and link"

.line 303
invoke-virtual {v1, v2, v0}, Landroid/content/Intent;->putExtra(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;
:try_end_0
.catch Ljava/lang/Exception; {:try_start_0 .. :try_end_0} :catch_0

I hope you are not doing something bad.

Wowww... I don't know how to thank you for this. I thought i'll give up with my last solution ie, setting two gettitle instead of link. Your answer solved my issue. Now i can set title and a custom text instead of link. btw, I'm not doing anything bad. I just want to add a "shared via(app name) text instead of the link. No bad intention at all. Thanks a lot. — user3548321, Apr 21 '16 at 04:49
