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.

Load your Word document into Aspose.Words for Android
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() + "/";
    com.aspose.words.License lic = new com.aspose.words.License();
    lic.setLicense(licString, this);
    com.aspose.words.Document doc = new com.aspose.words.Document(inputPath);
    com.aspose.words.ImageSaveOptions options = new com.aspose.words.ImageSaveOptions(SaveFormat.PNG);
    options.setPageCount(1);
    for (int i = 0; i < doc.getPageCount(); i++)
    {
        options.setPageIndex(i);
        doc.save(outputPath + "out_" + i + ".png", options);
    }
    Bitmap bm = BitmapFactory.decodeFile(outputPath + "out_1.png");
    ImageView img = (ImageView)findViewById(R.id.imageView1);
    img.setImageBitmap(bm);
}
catch (Exception e)
{
    e.printStackTrace();
}

Hope, this helps.

Best regards,

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:

Extract attached “dex2jar.zip” to "“C:\dex2jar”
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
Open “aspose-words-1.12-libs-android-jdk16.apk” with WinRar and extract “classes.dex” file to “C:\dex2jar”
Open command prompt in Windows and enter the following commands
C:\WINDOWS\system32>cd/
C:>cd dex2jar
C:\dex2jar>d2j-dex2jar.bat c:\dex2jar\classes.dex
dex2jar c:\dex2jar\classes.dex -> .\classes-dex2jar.jar
C:\dex2jar>
Now we have “classes-dex2jar.jar” which contains all the obfuscated classes
Copy this .jar to “~\HelloWorld\app\libs” folder of “HelloWorld” project
Now in Android Studio go to “Project Structure” of “HelloWorld” project
Under “Modules”, select “app” and go to “Dependencies” tab
Click ‘+’ and add a file dependency for “~\HelloWorld\app\libs\classes-dex2jar.jar”
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.

Hi Pratibha,

Thanks for being patient. To make this process simple, we will rebuild Aspose.Words for Android’s distribution package and consider shipping Aspose.Words for Android library the same way Google supplies its libraries (e.g. in .aar format). Your thread has been linked to the appropriate issue (WORDSANDROID-194) and you will be notified as soon as this issue is resolved. Sorry for the inconvenience.
