smali-如何在此代码中设置一些永久文本

Question

以下 smali 代码从字符串中获取 url，然后我们可以将 link 共享给其他应用程序。但我想发送一些永久文本而不是 url 或从字符串返回的文本。例如，我想分享 "hello, how are you" 而不是从字符串中获取的临时文本。那么我应该在下面的smali代码中更改什么来实现这个？

您的代码的某些类被混淆了，但通过一些猜测我们可以发现连接 html 文本的部分在这里：

iget-object v3, v6, Lcom/myapp/a/a/n;->c:Ljava/lang/String;

invoke-static {v3}, Landroid/text/Html;->fromHtml(Ljava/lang/String;)Landroid/text/Spanned;

move-result-object v3

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

move-result-object v0

如果我没记错的话，在 v0 中有将与其他应用共享的字符串：

invoke-virtual {v1, v2, v0}, Landroid/content/Intent;->putExtra(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;
