How to display word doc file in android using aspose word lib

I want to display word doc file, it should be from within app.

Is it possible to display word doc file using aspose word lib?

Hi Pratibha,


Thanks for your inquiry. Please note that Aspose.Words for Android is a class library and with it you can programmatically generate, modify, convert and render word processing documents. So, it does not offer any UI or control for performing these document processing tasks. However, if your’re intended to just preview your Word document in your android application, we can offer you a simple way that will help you in achieving what you are looking for.

  1. Load your Word document into Aspose.Words for Android
  2. Generate images against each page in Word document and then view them in some android control.

Please see the following code that uses standard ImageView widget to show Aspose.Words generated images:
try
{
String licString = Environment.getExternalStorageDirectory().getAbsolutePath() + “/Aspose.Words.Android.lic”;
String inputPath = Environment.getExternalStorageDirectory().getAbsolutePath() + “/input.docx”;
String outputPath = Environment.getExternalStorageDirectory().getAbsolutePath() + “/”;

Hope, this helps.

Best regards,

Thanks Awais,it really helpful for me.But when i integrate this code into my code then it will give me the following error.



Error:(97, 45) error: cannot access zzF4

class file for asposewobfuscated.zzF4 not found

Error:Execution failed for task ‘:app:compileDebugJavaWithJavac’.

> Compilation failed; see the compiler error output for details.

I have attached my MainActivity.java file here for reference.


Hi Pratibha,


Thanks for your inquiry. Please download this Android Studio test project. After that please do the following steps to generate .jar from .apk:

  1. Extract attached “dex2jar.zip” to ""C:\dex2jar"
  2. Go to “~\HelloWorld\app\src\main\assets” folder in “HelloWorld” project and copy “aspose-words-1.12-libs-android-jdk16.apk” to “C:\dex2jar” folder
  3. Open “aspose-words-1.12-libs-android-jdk16.apk” with WinRar and extract “classes.dex” file to "C:\dex2jar"
  4. Open command prompt in Windows and enter the following commands
  5. C:\WINDOWS\system32>cd/
  6. C:>cd dex2jar
  7. C:\dex2jar>d2j-dex2jar.bat c:\dex2jar\classes.dex
  8. dex2jar c:\dex2jar\classes.dex -> .\classes-dex2jar.jar
  9. C:\dex2jar>
  10. Now we have “classes-dex2jar.jar” which contains all the obfuscated classes
  11. Copy this .jar to “~\HelloWorld\app\libs” folder of “HelloWorld” project
  12. Now in Android Studio go to “Project Structure” of “HelloWorld” project
  13. Under “Modules”, select “app” and go to “Dependencies” tab
  14. Click ‘+’ and add a file dependency for "~\HelloWorld\app\libs\classes-dex2jar.jar"
  15. Under “Scope” column choose “Provided” value for this .jar and click OK and “Rebuild Project”.

Hope, this helps.

Best regards,

Hi Pratibha,


Thanks for the additional information. What IDE are you using for Android development? Please zip and attach your simple project causing this problem here for testing.
