Error message

the file count of %s, and the file count of %s is not equal, there must be some problem

What it means

Integrity check in ResourceApkBuilder.generalUnsignApk: after repackaging, the file count of the destination res directory (destResDir) differs from the raw res directory (rawResDir). Since resource obfuscation must rename but not add or drop files, a count mismatch proves the repackage corrupted or lost resources, so the build aborts rather than shipping a broken APK.

Solutions

1. Compare the files in the destination res directory and the raw res directory to find which resources were lost or added during resource shrinking/obfuscation
2. Check whether resource shrinking (mKeepRoot / res dir handling) accidentally deleted needed files, and adjust keep rules or disable the problematic shrink step
3. Re-run the build from an earlier clean state to rule out stale output in mOutDir

When it happens

Trigger: Thrown at AndResGuard-core/src/main/java/com/tencent/mm/androlib/ResourceApkBuilder.java:337 when the library encounters an invalid state.
