What Split APKs Are
A split APK is an app delivered as several files instead of one. One part holds the base app, and other parts hold resources for specific screen densities, processor architectures and languages. Stores deliver splits because they save bandwidth: your phone downloads only the parts it needs. This page is part of the Morphe app for Android patching collection.
Patching needs the whole app in one piece, so a split set cannot be patched part by part. The parts must be merged first, patched as one app, and installed as one finished file. That merge step is where split patching differs from plain patching.
How Morphe Handles Splits
Morphe merges split parts and skips modules for architectures, locales and screen densities the phone does not use, which keeps the merged app lean. It also strips native libraries for unsupported architectures from plain app files after patching, so the finished file carries only what the phone can run.
The practical rule is to give Morphe the full split set, not a single part. Select the folder or the set as the patcher asks, let the merge finish before judging the patch run, and expect the merge to take a little longer than a plain patch, because there is more file to assemble first.
For the next step, see Morphe Battery and Storage Tips in the guides, which continues this setup from where this page leaves off.
Split Patch Problems
If a split patch fails early, a part is usually missing. Re-download the full set and check that every part is present before patching. If the merged app installs but looks wrong, a density or locale part for the phone may have been skipped incorrectly, and patching with the full set again, without trimming options, usually fixes it.
If the patcher cannot find the split set, check how the set was saved. Split parts saved in different folders look like separate apps to a file picker, so keep one set in one folder with its original names intact.

Conclusion
Give Morphe the full split set in one folder, let it merge and trim what the phone does not need, and patch the merged result. A missing part, not the patcher, is the usual cause of a split patch failure.
