FileNotFoundException

Error message

FileNotFoundException

What it means

Thrown when FileUtils.getFdFromUri cannot open the content URI because the target file does not exist or the provider reports it missing; the FileNotFoundException is rewrapped as ApkFileException during ApkFile construction. Faulty input: apkUri pointing to a deleted/moved file or an unopenable provider entry.

Solutions

1. Verify the file/URI still exists before opening (it may have been deleted or moved)
2. Re-acquire the URI via the picker if the original grant/target is gone
3. Catch ApkFileException and inform the user the source package file is unavailable

When it happens

Trigger: Thrown at app/src/main/java/io/github/muntashirakon/AppManager/apk/ApkFile.java:266 when the library encounters an invalid state.

Common situations: See trigger scenarios.
