Error message

Apparently the install wasn't complete in the previous section.

What it means

After installing the APKs, restoreApkFiles re-queries PackageManagerCompat.getPackageInfo to confirm the package is now installed and to capture its UID. This error means the package could not be found even though installation was just attempted — i.e. the previous install step did not actually complete. AppManager throws this to signal an inconsistent restore state.

Solutions

1. Check logs from the install step (error 123 family) — fix the underlying installation failure first.
2. Verify mUserId matches the user the package was installed into.
3. Re-run the full restore; do not attempt KeyStore/data restore for a package that is not installed.
4. Confirm the package name in backup metadata matches the APK's actual package.

try { pm.getPackageInfo(pkg, GET_SIGNING_CERTIFICATES | MATCH_STATIC_SHARED_AND_SDK_LIBRARIES, userId); } catch (Exception e) { /* package absent — do not proceed with data/keystore restore */ }

boolean isInstalled(PackageInfo pi) { return pi != null && pi.applicationInfo != null; }

try { mPackageInfo = PackageManagerCompat.getPackageInfo(...); } catch (Exception e) { throw new BackupException("Apparently the install wasn't complete in the previous section.", e); }

When it happens

Trigger: getPackageInfo(mPackageName, GET_SIGNING_CERTIFICATES | MATCH_STATIC_SHARED_AND_SDK_LIBRARIES, mUserId) throws because the package is absent from the given user, immediately after the install call reported success or was skipped.

Common situations: The install in the previous section failed silently or was staged but never committed; installation targeted a different user than mUserId; the device removed the package between install and lookup; hidden/suspended package lookups failing on some OEM ROMs.

Understand the failure class

Background: "Invalid state transition" errors: "status must be X, actually Y", "already rejected/charging/uninstalled", "cannot ... while running" — what they mean when a library rejects your call — this error's family across 31 libraries.
