Java Runtime Exception When Using Navigation Drawer

I am trying to run my project but it crashes upon load. I have my proguard here as it has been the source of all issues so far and my error below that. I have tried: reinstalling

Solution 1:

Please add the following to your proguard file.

# keep classes with the `View(Context, Attributes)` constructor
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

# keep classes with the `View(Context, Attributes, int)` constructor
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

# keep methods that accept a view as their argument.
# This would be the case if you set an onclick from an xml file
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# keep all of the design library
-keep class android.support.design.** { *; }

# keep all android classes
-keep class android.** { *; }

# keep all class members, don't rename methods
-keepclassmembers class android.** { *; }
