Android 5.x ClassNotFoundException在6.0+上运行正常

Question

I have updated my project's minSdkVersion from 19 to 21. This has caused an issue on 5.0/5.1 devices where I can't run the app. I keep getting a ClassNotFoundException on my Application class. The full log, Application class, and gradle file are below. If I revert my project back to minSdkVersion 19 then the app will run on 4.4+ with no problems.

What I have tried

• Cleaning/Rebuilding

• Updating and downgrading the build tools version

• All support library's across projects have same version number

• Making all my manifest classes relative and then absolute

• Updated all Sdk and build tools

Answer 1

When targeting api 21 the compiler has a limit of 100 dex files it will read. So a simple solution I found was to add this to your dexOptions in your gradle file. This will merge all your dex files into the lowest possible amount.

In your build.gradle file add the following

android {
    ...
    dexOptions {
        preDexLibraries = false
    }
}

Answer 2

Please try to disable the Instant Run option and then run the app . It worked for me after trying lot of solutions I finally solved this.

Answer 3

This means your multiDex does not work properly so some files are missing. I think android 5.0 has the different way to use the multiDex. Did you override something in your Aplication class?

Answer 4

Try removing compile 'com.android.support:multidex:1.0.1' . The Google doc says

Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library.

I am by no means sure if this helps, but it may be worth trying.

Answer 5

For some reason, this class is not in your main dex anymore.

Declare the class in the main-classes list , using multiDexKeepFile (listing the classes in gradle) or multiDexKeepProguard (pointing to a specific proguard file for the main classes).

Answer 6

Try enabling Progaud and disabling multidex.

You'll not only fix this problem, but you'll have a smaller apk with faster install and run times.

Note, If you need help with this just leave a comment and we can work it out.

• Ok, so its not Progaurd or MultiDex

The error is that com.package.Application is missing. None of the code you posted (or the manifest) contains a reference to that class. Where are you defining com.package.Application? and if you aren't where in your project is it being referenced? (I'd do a project wide search for "com.package.Application" to unravel this.)

Answer 7

try giving full path in manifest-

  <application
        android:name=".TestApplication"

Also delete the build folder manually-sometimes clean doesn't work.Also uninstall the app manually and start.

Answer 8

I have made demo from your code and configuration and its working in below marshmallow

Download and check it and compare with your code. And one more thing how you have created project with package name com.package.testapp. I am not able to create project with same package name

Answer 9

Create multidex-config.txt to keep this classes in the primary DEX file:

com/package/Application.class
com/package/TestApplication.class
com/package/testapp/welcome/TestClaimApplication.class

Add multiDexKeepFile to android.buildTypes.release section of your build.gradle like this:

android {
    buildTypes {
        release {
            multiDexKeepFile file 'multidex-config.txt'
        }
    }
}

Answer 10

Do you need multidex enabled? I have always run into issues with it. I always understood multidex to be used as a last resort if you are still hitting the 65k method limit. If you are not running into this method limit, you do not need multidex. If you are running into this limit, I would suggest using progaurd to remedy the issue first. If you are still above the method limit even after using proguard, then use multidex.

Answer 11

You need to add your android:name with complete path like this.

android:name="android.support.multidex.MultiDexApplication" 

And your TestApplication should extend MultiDexApplication.

According to the documentation, please refer if need more details. MultiDex Documentation
