So after some further follow-up I can confirm there are two fixes: 1) Just print out the value of the variable in a Log.d. Believe it or not, that "fixes" the code. 2) Change "float" into "double".
Based on customer reports I received, the bug only affected users running API 15 or 16, and only some models of phones, not all (again, based on customer reports). Still if you guys switch to Gradle using Proguard 4.9 with obfuscation on (even with optimization off), might want to watch out for floating point conversions in your code, or just compile with obfuscation off or export with Eclipse.
