For more information about how to use the APKExpansionPolicy when you're not using the Downloader Library , see the documentation for Adding Licensing to Your App , which explains how to implement a license policy such as this one. Once your APK expansion files are saved on the device, how you read your files depends on the type of file you've used. Regardless of how you read your files, you should always first check that the external storage is available for reading.
There's a chance that the user has the storage mounted to a computer over USB or has actually removed the SD card. Note: When your app starts, you should always check whether the external storage space is available and readable by calling getExternalStorageState. This returns one of several possible strings that represent the state of the external storage. As described in the overview , your APK expansion files are saved using a specific file name format:.
To get the location and names of your expansion files, you should use the getExternalStorageDirectory and getPackageName methods to construct the path to your files. Here's a method you can use in your app to get an array containing the complete path to both your expansion files:. You can call this method by passing it your app Context and the desired expansion file's version.
There are many ways you could determine the expansion file version number. One simple way is to save the version in a SharedPreferences file when the download begins, by querying the expansion file name with the APKExpansionPolicy class's getExpansionFileName int index method.
You can then get the version code by reading the SharedPreferences file when you want to access the expansion file. For more information about reading from the shared storage, see the Data Storage documentation.
This is an optional library that helps you read your expansion files when they're saved as ZIP files. Using this library allows you to easily read resources from your ZIP expansion files as a virtual file system. 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.
For example, when using the zip tool, you should use the -n option to specify the file suffixes that should not be compressed:. The above code provides access to any file that exists in either your main expansion file or patch expansion file, by reading from a merged map of all the files from both files.
Context and the version number for both the main expansion file and patch expansion file. If you'd rather read from a specific expansion file, you can use the ZipResourceFile constructor with the path to the desired expansion file:.
For more information about using this library for your expansion files, look at the sample app's SampleDownloaderActivity class, which includes additional code to verify the downloaded files using CRC. Beware that if you use this sample as the basis for your own implementation, it requires that you declare the byte size of your expansion files in the xAPKS array.
Before publishing your app, there are two things you should test: Reading the expansion files and downloading the files. Before you upload your app to Google Play, you should test your app's ability to read the files from the shared storage. All you need to do is add the files to the appropriate location on the device shared storage and launch your app:. For example, if your package name is com. Plug in your test device to your computer to mount the shared storage and manually create this directory.
For example, regardless of the file type, the main expansion file for the com. The version code can be whatever value you want. Just remember:. Because your app must sometimes manually download the expansion files when it first opens, it's important that you test this process to be sure your app can successfully query for the URLs, download the files, and save them to the device.
To test your app's implementation of the manual download procedure, you can publish it to the internal test track, so it's only available to authorized testers. If everything works as expected, your app should begin downloading the expansion files as soon as the main activity starts.
Note: Previously you could test an app by uploading an unpublished "draft" version. This functionality is no longer supported. Instead, you must publish it to an internal, closed, or open testing track.
Updating Your app One of the great benefits to using expansion files on Google Play is the ability to update your app without re-downloading all of the original assets. Because Google Play allows you to provide two expansion files with each APK, you can use the second file as a "patch" that provides updates and new assets. Doing so avoids the need to re-download the main expansion file which could be large and expensive for users. The patch expansion file is technically the same as the main expansion file and neither the Android system nor Google Play perform actual patching between your main and patch expansion files.
Your app code must perform any necessary patches itself. Note: Even if you only need to make changes to the patch expansion file, you must still update the APK in order for Google Play to perform an update.
If you don't require code changes in the app, you should simply update the versionCode in the manifest. As long as you don't change the main expansion file that's associated with the APK in the Play Console, users who previously installed your app will not download the main expansion file.
Existing users receive only the updated APK and the new patch expansion file retaining the previous main expansion file.

Click on one of the magnet links to see if Chrome opens it with BitTorrent automatically.
If Chrome is not working as intended or the setting was toggled on by default but Chrome is still not playing nicely with magnet links, you will have to dig deeper into Windows' registry settings. Why is it happening if you have a torrent client already installed? This is happening because Chrome or Windows is unable to detect the right application for the job. It fails to associate the magnet link with the torrent client.
Here you can enter a number of commands to help you manage your PC. We will enter 'regedit' in the box. This will open the Registry Editor in a new window. Now you must navigate to the following file location. Check the screenshot below to better understand the folder structure. You may have to scroll a lot here. In the right pane, you will see the Data column which will show the complete directory path of the BiTtorrent client. Your job here is to make sure that the BitTorrent client resides in the same directory that you see here.
In my case, it must be here:. Notice the. That means it is linking to an executable file which should launch when need be. Ignore the random string of text after that. Now open C drive in a new window and begin the drilling process. In case your torrent client is located in a different folder, you will have to edit the registry entry under Name column. Go back to the torrent site of your preference in Chrome and try opening a magnet link again.
It should work now.
