Since Anbox currently does not come packaged with an app store, the only way to install applications is through ADB as follows:
adb install /path/to/file.apk
I have been able to successfully install QuickPic and Snapseed this way, however when I try to install Opera Mini or WPS Office, I receive the following error:
Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]
I'm wondering whether this is an Anbox problem, Ubuntu problem, or ADB problem, and how I can fix it?
