It seems like this error message can have many different causes   The case I came across was on a real device  so the emulator bases solutions did not apply    Basically  when this happens  set your Logcat filter to Verbose or Warn  which will help you get more information about the cause   In my case  multiple or conflicting versions of JUnit were being included in the project I was working on  a large existing codebase   The Android app I was trying to deploy had several library projects as dependencies  and I had mistakenly set things up to include multiple JUnit jar files   I discovered this based on a series of Logcat messages  Note that the WARN line gives the cause   DEBUG dalvikvm 4808   DexOpt   Ljunit framework TestSuite 1   has an earlier definition  blocking out 11-06 14 30 10 973  WARN dalvikvm 4808   Invalid file flags in class Ljunit runner Sorter Swapper   0209 11-06 14 30 10 973  null libc 4808   Fatal signal 11  SIGSEGV  at 0x00000004  code 1   thread 4808  dexopt

I was getting this issue when trying to install on 2 3 devices  fine on 4 0 3   It ended up being due to a lib project i was using had multiple jars which were for stuff already in android e g  HttpClient and XML parsers etc  Looking at logcat led me to find this as it was telling me it was skipping classes due to them already being present  Nice unhelpful original error there

If you have error INSTALL FAIL DEXOPT  see in manifest android targetSdkVersion   Set version  lt  21 sample       android targetSdkVersion  19    This worked for me

User · Answer

There s no generic solution  you have to find the error reported on your Logcat to be able to figure it out  Sometimes it s a class that can t be  dexed  due to an usage of a class not available on the specified Target API for instance  Or it could be a class that you re making reference in your code  but the library that it is in is not being packaged

I got the same error and fixed it by increasing the size of internal storage   The internal storage was initially set to 32MB I know  and then I installed a couple of apks on it  which had left less space  than what was needed for the one to be installed

I had this problem when there were some Unicode characters in my method names  due to  of all things  copy pasting from a powerpoint file  that Dalvik did not like  You can see this by looking at Logcat output while trying to install the APK   This was on a real device

This seemed to be related to disk space for me  A newly rolled 5 1 emulator boots with a  low on disk space  error - and looking at the emulator properties  the default space allocated for internal storage is 800MB which seems low   Solution  therefore was to increase this  I went to 4GB   Oddly the emulator still boots with the same disk space warning but factory resetting it  Settings --  Backup and Restore inside the emulator  solved it entirely for me   Just a bit odd that it doesn t work out of the box with default settings

INSTALL FAIL DEXOPT usually has to do with the limit placed on classes dex  On anything pre-ICS dexopt will fail on anything over 5 MB  Recent versions of Android use an 8 or 16 MB buffer   Check the size of classes dex in your APK  It would also be good to see what your method count is  as dex has a 65536 method field limit     References   Error while installing application  INSTALL FAILED DEXOPT   https   www facebook com notes facebook-engineering under-the-hood-dalvik-patch-for-facebook-for-android 10151345597798920  How to shrink code - 65k method limit in dex

classes dex does not make it to the final  apk  Running gradlew --offline clean  amp  amp  gradlew --offline assembleDebug fixed things for me every time  From that point you can start launching the app from Android Studio again   EDIT  Before what I said above go to Task Manager and kill all cmd exe and conhost exe processes  or just the one in which aapt got stuck   Otherwise aapt would crash from now on when launched from command line with the infamous error -1073741819

User · Answer

One reason is that classes dex is not found in the root of the  apk-package  Either    this file is missing in the apk-package or  it is located in a subfolder within the  apk file     Both situations cause the termination because Android supposedly searches only in the root of the apk file  The confusion is because the build run of the  apk file was without an error message   Core reasons for that error may be    The dx tool need classes dex in the current main working folder  But in reality classes dex is located somewhere other  aapt have a wrong information for the location for classes dex  For example with aapt exe add     bin classes dex  Thats would be wrong because classes dex is in a subfolder  bin of the created  apk file

As this seems to be a problem I have myself encountered multiple times and this time none of the shared solutions helped me  I ll still post what helped me personally and what I believe may help someone else in future   Go to your project s directory and find build intermediates dex-cache cache file  Remove it - as name suggests  it s a cached dex file that may be outdated if you have made changes to your project s dependencies  build tools version etc
