Ich entwickle eine Android-Anwendung. In dem ich die doc-, docx-, xlx-, xlsx-Dateien in meiner Anwendung anzeigen möchte.

Nachdem ich in Google gesucht hatte, erfuhr ich, dass der Apachi-POI diese Dateien in HTML konvertiert. Damit ich das @ hinzugefügt ha "poi-3.8-20120326.jar" in den libs Ordner und versuche die App zu erstellen. Aber ich hatte ein Dalvik-Build-Problem.

Also, ich habe nach diesem Problem gesucht und festgestellt, dass das POI-Jar Java-Apps unterstützt, die für Android nicht vollständig unterstützt werden.

Ich habe OpenSource zum Konvertieren von ppt- und pptx-Dateien.https: //github.com/qhm123/POI-Androi

In diesem Quellcode haben sie den Apache Poi-Quellcode heruntergeladen, den Quellcode in die App eingefügt und ihn zum Konvertieren der ppt- und pptx-Dateien verwendet.

So habe ich den folgenden Code für doc, docx pages to html verwendet.

WordToHtmlConverter.main(new String[]{"/sdcard/office/sample.doc", "/sdcard/office/sample.html"});

Dafür habe ich in meinem App-Projekt das Paket "org.apache.poi.hwpf" hinzugefügt. Aber ich habe das gleiche Dalvik-Build-Problem, das ich oben erwähnt habe. Daher konnte ich die App nicht erstellen.

Wie kann ich das mit dem Apache POI machen?

Dalvik Fehler:

[2014-12-01 13:55:27 - POI-operations] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.log4j.chainsaw.ControlPanel$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a

this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.
