apk-expansion-files

问题 I'm setting up Google's APEZProvider to read .PNGs (compressed) and .MP3s (not compressed) from an APK Expansion zip file. File retrieval works just fine if I avoid the URI, and stick to "getAPKExpansionZipFile()" But when I try to retrieve my files using the "content://" API, I am getting a null InputStream. (I need the URI to satisfy the APIs of media players.) This is for an Android app targeting API 26. In the past I was able to get the content provider working. But I've broken something.

问题 In the documentation it says: If you're using your expansion files to store media files, a ZIP file still allows you to use Android media playback calls that provide offset and length controls (such as MediaPlayer.setDataSource() and SoundPool.load()). I have 10 small .ogg files and I want to use SoundPool.load (FileDescriptor fd, long offset, long length, int priority) to load these audio files. I've written some code, but when I run it I get error message: "Unable to load sample: (null)" ,

问题 I'm following all official expansion files guides, but i can't find it. I'm unable to access the contained obb file i need. I need 6 audio files (80Mb) that i "stored" (uncompressed) in a zip file and renamed as 'main.2001.test.expansion.proj.obb' and stored in '/mnt/sdcard/Android/obb/test.expansion.proj/' I'll try to access to the files String mainFileName = Helpers.getExpansionAPKFileName(this,true,2001); if(!Helpers.doesFileExist(this, mainFileName, 27959282L, false)) { //download } else

问题 This is not related with kitkat bug, i'm testing in 4.4.2 I can mount without problems the obb file, the problem is when try to do the same with encrypted obb. I'm using jobb in windows like this: jobb -d my_folder -o exp.obb -k pwd -pn com.example.name -pv 1 The only thing i changed to load encrypted obb file is this: stgMgr.mountObb(mObbPath, null, new mOnObbStateChangeListener) stgMgr.mountObb(mObbPath, pwd, new mOnObbStateChangeListener) it's not a permissions problem. So, why i cant

问题 I am trying to do an application which contain ~80mo of PNG (It's an offline app so I have to store them on the phone). The application works perfectly in local but I can't upload an apk > 50mo. So I am trying to implement an expansion file which will contain all my PNGs. So I use this simple command on Linux: _zip_ -0 _main.1.com.ctai.irisst.zip_ *_.png_ on my /res/drawable-mdpi to create my expansion file and then put it manually to /Android/data/com.ctai.irisst/ Then, I use this code to

问题 Currently I am preparing a demo for including Expansion File into a developed project. I have followed this Tutorial. After a lot of struggle I am able to run the demo application but having issues in displaying progress for downloaded data. I have uploaded obb file on play store which is 1,060,024 bytes and on disk size is 1,060,864 bytes . following is code snippet where I think problem can be. private static final XAPKFile[] xAPKS = { new XAPKFile(true,6,1060024L) }; void

问题 I implemented apk expansion successfully and OBB file downloaded at Storage->Android->Obb->PackageName->main.1.com.packagename.obb But when i go to extract i am getting issue is "Not a Zip archive". ZipResourceFile zrf = new ZipResourceFile(fileName); public ZipResourceFile(String zipFileName) throws IOException { addPatchFile(zipFileName); } void addPatchFile(String zipFileName) throws IOException { File file = new File(zipFileName); RandomAccessFile f = new RandomAccessFile(file, "r"); long
