2017-01-23Check crc and time of secondary dex filesandroid-o-preview-1android-n-mr2-preview-2o-previewYohann Roussel
Protect extracted dex files from modifications by checking their crc and modification time. In case of change, proceed to a new extraction. Those checks are replacing the check of the zip integrity by opening it with a ZipFile. Test: SupportMultidexHostTest (from tradefed) Bug: 32159214 Change-Id: I09aa01550782f5f550bee6fc91709455e82c1057
2017-01-20Check extracted dex only once per usageYohann Roussel
The check is unnecessary in MultiDex.install because it was already done by MultiDexExtractor.load. The retry on bad extraction is also included in MultiDexExtractor.load so it was redundant too. Test: SupportMultidexHostTest (from tradefed) Change-Id: I877a99db0e0c562ac47a7c5c87d7f3e1d70884e6
2017-01-20Mark extracted dex files as read onlyYohann Roussel
This is a poor protection from some attack against application that would be made to overwrite their extracted secondary dex files. The protection is poor because marking the dex files read only will protect only some applications depending on their implementation.

2017-01-13Merge "Prefix temp files to ensure they are cleaned up"Justin Morey
2017-01-13Use context.getApplicationInfo()Jon Noack
Due to package install races it is possible for a process to be started from an old apk even though that apk has been replaced. Querying for ApplicationInfo by package name may return information for the new apk, leading to a runtime with the old main dex file and new secondary dex files. This leads to various problems like ClassNotFoundExceptions. Using context.getApplicationInfo() should result in the process having a consistent view of the world (even if it is of the old world). The package install races are eventually resolved and old processes are killed. Test: Passes Google Play services tests Change-Id: I95257d851eb678c55a19e731183f7add2b540615
2017-01-13Prefix temp files to ensure they are cleaned upJon Noack
Temp files are removed unconditionally in a finally block following extraction. However, if the process is killed during extraction this finally block will not run. Because temp files started with extractedFilePrefix, they wouldn't be cleaned up in prepareDexDir(). This change ensures that prepareDexDir() will remove any existing temp files before extraction begins.

2016-05-17Fix handling of suppressed exceptionandroid-n-preview-4Yohann Roussel
On API 19 and 20, the library was trying to save "suppressed exceptions" in the loader.dexElementsSuppressedExceptions but the field is not there, it's in DexPathList, so the correct path is loader.pathList.dexElementsSuppressedExceptions.

2015-05-26Use Context.getFilesDir as a backup dex locationandroid-m-preview-2Yohann Roussel
On some devices it seems impossible to read or write the application data directory. There, creating code_cache at the proper location is impossible. In this case fallback to the 'files' directory. This may lead to not cleaning the useless extracted secondary dex files if one such devices is ever updated to L.

2014-04-09Change update detection to reduce load time.Yohann Roussel
Reduces load time if extraction was already made. It appeared that new ZipFile was really slow because it's preparing much things as soon as it's instanciated. The new criteria consist of the last modified time of the apk plus the crc of the apk's central directory, last modified time should be enough for nearly all modifications and the crc is here to try to handle an OTA mixing with dates. The transition from old criteria to new should be good: since there will be no stored values they would be detected as a new installation. Change-Id: Id390b77b03d794b8b7feb91eb0daae1126c6d691

2014-01-17Remove the check for source apk file sizeMaurice Chu
The file deletion when finding that the source apk file size was different than what was stored in SharedPreferences causes a race condition when multiple processes are executing this code, where one process could erase the secondary zip file while a different process had already started to create the zip file. This check is unnecessary and has been removed. Also, changed the parameter for getting the SharedPreferences to Context.MODE_MULTI_PROCESS, which forces a re-read of the key/value pairs from the file. This should also fix the original bug b/12550057. Bug: 12594955 Bug: 12550057 Change-Id: I53f4bca0d03a5737d802509274520a78effcf228
2014-01-15Check whether to extract secondary dex files based on apk size and CRCMaurice Chu
This addresses an edge case where the secondary dex is not reloaded when it should because of an OTA due to the modification time of the PrebuiltGmsCore.apk in the system image is never different even though PrebuiltGmsCore.apk may have changed in the OTA. This performs two checks, the first is that the overall size of the apk is the same. The second is to check that the number of dex files are the same, and the CRC values of the dex file zip entries are the same. Bug: 12550057 Change-Id: I526f6b88cfc7957840b0c35aaad0eab0cd776f7e
