How to check an APK’s package name before installing

Match the application ID before the display name

The Picasso app covered by this website uses com.offshore.picasso. Android’s application ID identifies the app on a device. A file named “Picasso.apk” can contain a different package, while two copies of one package can have different filenames.

Use the full ID, including every letter, when comparing an installed app, store listing and manual download. Android’s update rules also require compatible signing and version information. Matching the ID is a useful first check; it does not identify who controls the signing key or establish safe behavior.

What a real file inspection found

On 14 October 2026, the file supplied for this website was inspected without installing or executing it. Its filename was Pikashow.apk. The manifest identified com.pikashow.mobile, with display version v94.1 and version code 2. That package did not match the Picasso identity above.

The record also contains a size of 21,649,156 bytes and a SHA-256 digest. These values describe that historical artifact, not a current Picasso release.

The site owner chose to exclude the file from the Picasso download flow. This article provides no download link for it. The inspection established the package mismatch; it did not test playback, verify publisher ownership or produce a malware verdict.

Inspect an APK with Android’s tools

On a computer with the Android SDK Build Tools installed, AAPT2 can print the package name and other manifest information. Substitute the path to the file you are examining:

aapt2 dump packagename "download.apk"
aapt2 dump badging "download.apk"

Read the reported package and version fields, then compare them with a trusted publisher or store reference. Preserve the exact command output with the source and retrieval date. AAPT2 reads package metadata; these commands do not run the app.

Use tools from Android’s official SDK distribution. Uploading a private or unpublished app to an unfamiliar online checker would share that file with another service. Local inspection avoids that transfer.

Record which bytes you inspected

On Windows, PowerShell’s Get-FileHash can calculate the SHA-256 digest locally:

Get-FileHash -LiteralPath ".\download.apk" -Algorithm SHA256

Compare it with a digest supplied through a source you trust. A matching hash is evidence that the compared file contents match. It does not establish that the reference file is harmless, licensed or published by the expected developer.

Signing checks are a separate step. Android provides apksigner for signature verification. Extracting a certificate fingerprint alone is not the same as verifying signature integrity or the signer’s real-world identity. For the wider decision, read what hashes and signing establish and how this site compares sources.
