My app is building and running ok when using devices with Android 6.0 or Android 7.0 but when running any device with Android 5.1 (Haven't tested lower) it fails with the following exception:

I've made sure that i have included all the necessary libraries in my gradle file (In this case, the log shows a google library but it has happened with others). I've also made sure that Multidex is enabled and tried cleaning and rebuilding the project as well as deleting the app and reinstalling.
I've isolated some conditions that may be causing the crash:
- Instant Run is disabled
- Building the app for multiple devices
I'm using Android Studio 2.2RC
Edit: Still happening with the stable 2.2
回答1:
Here what we can see in runtime/dex_file.cc
bool DexFile::OpenFromZip(...) {
...
while (i < 100) {
std::string name = StringPrintf("classes%zu.dex", i)
...
}
...
}
So if you have more than 100 dex files you get this NoClassDefFoundError.
There are issues in the tracker for this behavior:
https://code.google.com/p/android/issues/detail?id=234367 https://code.google.com/p/android/issues/detail?id=170485
It is possible to avoid this error by disabling pre-dexing. So you can put something like
subprojects {
project.plugins.whenPluginAdded { plugin ->
if ("com.android.build.gradle.AppPlugin".equals(plugin.class.name)) {
project.android.dexOptions.preDexLibraries = false
} else if ("com.android.build.gradle.LibraryPlugin".equals(plugin.class.name)) {
project.android.dexOptions.preDexLibraries = false
}
}
}
in the root build.gradle file.
回答2:
Android 5.1 has an arbitrary limit of 100 dex files
One possible workaround is to disable preDexLibraries which reduces the number of classes.dex files included in an apk.
Add
android {
dexOptions {
preDexLibraries false
}
}
to the app's build.gradle file
回答3:
Make sure you're using the updated versions of google.android.gms
Invalidate Caches and then Make changes in your app : gradle file :
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
//noinspection GradleCompatible
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:23.4.0'
implementation 'com.android.support:design:23.4.0'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.parse.bolts:bolts-tasks:1.4.0'
implementation 'com.parse:parse-android:1.13.0'
implementation 'com.android.support:multidex:1.0.3'
This worked for me
