我使用Dropbox SDK下載保存在保存在Dropbox中的文件。我使用AsynTask內部此方法:Android使用Dropbox Api java.lang.VerifyError:com/dropbox/client2/RESTUtility
@Override
public void downloadData() {
String filePath = getApplicationContext().getFilesDir().getPath().toString() + "/routes.xlsx";
File file = new File(filePath);
try {
FileOutputStream outputStream = new FileOutputStream(file);
DropboxAPI.DropboxFileInfo info = mDBApi.getFile("routes.xlsx", null, outputStream, null);
Log.i("DbExampleLog", "The file's rev is: " + info.getMetadata().rev);
RemoteResourcesLogic remoteResourcesLogic = new RemoteResourcesLogic();
remoteResourcesLogic.read(filePath);
} catch (Exception e) {
Log.i("DbExampleLog", "Error getting folder");
}
}
的問題是精確地:DropboxAPI.DropboxFileInfo信息= mDBApi.getFile( 「routes.xlsx」,NULL,OutputStream中,NULL);
我在libs文件夾中的所有neccessary的.jar:
- 的HttpCore-4.0.1.jar
- 的JUnit 4.10.jar
- json_simple-1.1.jar
- httpmime-4.0。 3.jar
- 的HttpClient-4.0.3.jar
- 的Dropbox,Android的SDK-1.6.3.jar
- bcprov-jdk16-146.jar
和兩個罐子閱讀XSLX文件:
- AA-POI 3.10分鐘-0.1.5.jar
- AA-POI-OOXML-架構 - 3.10 - 減少 - 更多 - 0.1.5.jar
有人能幫助我嗎?

感謝格雷格。我已將「/」添加到mDBApi.getFile(「routes.xlsx」,null,outputStream,null);在Android Studio中,我切換到Project視圖,並且可以看到libs文件夾,並且我看不到「json_simple-1.1.jar」和「dropbox-android-sdk-1.6.3.jar」的「添加爲庫」選項。你能幫我嗎? Regards – user2316075
如果「添加爲庫」選項不存在,則可能已經完成。也許嘗試刪除並重新添加罐子? – Greg
