android - ClassNotFoundException: Didn't find class on path: DexPathList -


i have problem since updated app on playstore. since update, exception thrown, haven´t changed related exception.

stacktrace:

the thing is, app version before runs without problems , haven´t changed related activity. i´ve added new info dialog has nothing activity. app free lite version, i´ve made exact same changes on pro version , there nothing thrown. works expected. difference between pro , lite is, have integrated admob (on new way) in lite version , google play license in pro version. have integrated since beginning , haven´t made changes this. haven´t made changes manifest, read many posts here nothing helps.

it seems happen on android versions since 5.0 . has idea problem cause or has same experiences? possible proguard destroyed obfuscating (also here, no changes)?

i posted no code, because not important problem, said haven´t made changes related exception.

this question marked duplicate isn´t. comment link doesn´t fix problem, libraries checked , integrated in right way. also, don´t use ndk.

update

after long time, turned out must have proguard. can´t error causes, tried little bit , that´s noticed (that´s in case eclipse ide):

  • i have close every tab project want sign
  • i have clean project , after cleaning, nothing export apk
  • making small change in manifest, save , undo change (and save)
  • if there class in manifest named "yourclass" or ".yourclass", change "com.yourpackage.yourclass"

that 4 points have done , worked. looks suspicious, think there problem obfuscating. because without doing these points, can compile apk , install eclipse. me, there no obvious reason behavior. package name work without change if install eclipse. hope these points can somebody.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
