Because of my large application, i have to use MultiDex to split my app for pre Lollipop devices. When debugging my app on my Nexus 4 (ICS 4.3), i get the following errors.
Why were my classes not found?
defaultConfig {
applicationId "de.itout.bring.handsoffme"
minSdkVersion 17
targetSdkVersion 23
versionCode 6
versionName "1.2"
multiDexEnabled true
}
buildTypes {

minifyEnabled false

signingConfig signingConfigs.release
}
debug {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dexOptions {
//javaMaxHeapSize "512m"
//preDexLibraries = false
javaMaxHeapSize "4g"
incremental true
}

@razzledazzle: Thanks a lot. These tips are very helpful.
After that, I´ve the next problems. In my apk-file missing classes respectively classdefinitions. SOME sugarmodels-classes was missing (NOT ALL). The little tool classyshark and the sugarlog help me! So I compare the classes and found a solution!
For all Sugar-ORM-Users with multiDex problems. I put the "ignore"-Annotation for a debugvariable in all my sugarclasses and now they are in the dexfile. I don´t know how or why, but it works...
@Ignore
public boolean multiDex;
Maybe there is better solution, but I don´t know... Possibly the RetentionPolicy of the Ignore-annotation do the trick.
Next thing for possible Sugar-Orm problems could be the proguardtool. It is important to keep the classnames of your models.
-keep class com.package.example.models.* {*;}
these rule keep the complete class for proguard. I hope it help.
Happy coding...
