Error while creating android app: java.util.zip.ZipException: duplicate entry: com / sun / mail / handlers / message_rfc822.class
I am developing an Android application that interacts with Picasa Web Albums. So I tried to upload a photo using the following code.
protected Integer doInBackground(String... params) {
int index = 0;
int count = 0;
URL albumPostUrl = null;
try {
albumPostUrl = new URL("https://picasaweb.google.com/data/feed/api/user/"+googuserName+"/albumid/" + params[1]);
}
catch (Exception ex)
{
ex.printStackTrace();
}
while(index < totalFBPicsCount)
{
PhotoEntry myPhoto = new PhotoEntry();
myPhoto.setTitle(new PlainTextConstruct(params[2] + "_" + index));
myPhoto.setClient("Photo Sync");
MediaFileSource myMedia = new MediaFileSource(new File(params[0] + "/" + params[2] + "_" +index + ".jpg"), "image/jpeg");
myPhoto.setMediaSource(myMedia);
try
{
PhotoEntry returPic = myService.insert(albumPostUrl, myPhoto);
}
catch (RuntimeException ex)
{
ex.printStackTrace();
}
catch (Exception ex)
{
ex.printStackTrace();
Log.e("Sai", "PhotSync", ex);
}
index++;
}
return null;
}
myService.insert(albumPostUrl, myPhoto)
I got the following exception while executing the line . The logcat trace is shown below:

After a bit of searching, it turned out that I have to use the android port for Java Mail from here . But when I added mail.jar
, activation.jar
and additional.jar
and tried to build the app, I get the following error in the Gradle console.
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: com/sun/mail/handlers/message_rfc822.class
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Then I see there are activ-1.1 and mail-1.4 libraries in External Libraries in addition to the libraries in the libs folder (mail.jar, activation.jar, Additional .jar). External libraries (mail-1.4 and activation-1.1) are automatically included as they are required dependencies for the Google Data Java Client Library that I use to get data from picasa. Below build.gradle
:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "krishtech.photosync"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/LICENSE.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.facebook.android:facebook-android-sdk:4.1.0'
compile 'com.google.android.gms:play-services-identity:7.5.0'
compile('com.google.gdata:core:1.47.1')
compile('com.google.api-client:google-api-client:1.16.0-rc') {
exclude(group: 'xpp3', module: 'xpp3')
exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
exclude(group: 'junit', module: 'junit')
exclude(group: 'com.google.android', module: 'android')
}
compile('com.google.api-client:google-api-client-android:1.16.0-rc') {
exclude(group: 'com.google.android.google-play-services', module: 'google-play-services')
}
compile files('libs/activation.jar')
compile files('libs/additionnal.jar')
compile files('libs/mail.jar')
}
So now I'm fixing myself. If I need to delete mail-1.4 in the External Libraries folder (which I cannot do, please let me know how to do it) then I can cause an error in the gdata library and if I do not enable the java mail port .jar Maybe I can not upload photos. Please suggest how to fix this problem.

Well I solved this problem. The trick was to exclude mail-1.4.jar
that comes with com.google.gdata:core:1.47.1
to be included when you create the app. Made the following changes to build.gradle and now my app is working and also I can upload to Pics in Picasa using the android port for the Java mail library.
compile('com.google.gdata:core:1.47.1') {
exclude(group: 'javax.mail', module: 'mail')
}
