Noclassdeffounderror: com.itextpdf.text.Document error after updating SDK

I have a database on sqlite on Android, and export report to pdf using the library itextpdf.

But recently after updating the Android SDK, it started from the error in the line below:

Document document = new Document();

The error that occurs:

Caused by: java.lang.Noclassdeffounderror: com.itextpdf.text.Document

I didn’t change the class, I just upgraded the version of SDK 22 to SDK 23.

I’m having this problem on devices prior to Android 5.0. Version 5 onwards works normally.

Before:

dependencies {
    compile 'com.itextpdf:itextpdf:5.5.8'
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
}

Now:

defaultConfig {
        multiDexEnabled true
}
android {
    useLibrary 'org.apache.http.legacy'
}
dependencies {
    compile 'com.itextpdf:itextpdf:5.5.8'
    compile 'com.android.support:support-v4:23.2.1'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.google.android.gms:play-services:8.4.0'
}

Does anyone have any suggestions of what might be?

  • Welcome to sopt. Your question is somewhat incomprehensible, a lot of code mixed with loose texts, it is difficult to understand. First explain what is.

  • This problem started to appear after I upgraded the sdk to 23, I use asynctask to call in the background, but it gives error. Strange that it’s only on some devices. The same code worked well before, I did the debug apk test and the only one that worked at all was the one that used sdk 22

  • I have two device for testing, one with version 5.1 that works normally is one with version 4.3 that stopped generating the pdf. I haven’t tried it in the emulator because if it worked before, it might be something with sdk I don’t know, I’m a beginner in Java programming. And I have no idea where to start.

  • I gave an improved question to make it easier for people to understand, any additional information they find necessary, just edit the question.

  • Thank you Diego, it’s the first time I put something on, because I couldn’t find a solution.

Problem solved.

In logcat appeared the following message, before the error.

Could not find class 'com.itextpdf.text.Document',

And searching the Internet, I found that it might be something related to multiDexEnabled which is not required in previous versions, and also by calling all google dependencies compile 'com.google.android.gms:play-services:8.4.0', that in this case I removed that I put only what I needed. that’s where it worked.

I don’t really know the solution but some dependency on Google was in conflict.

But it serves as a warning to use only the necessary and always check the logcat, which informed the missing class even before the error.
