before installing an apk, check the package name
The Android install screen shows a package name and signature digest. If the package name does not match the official page, stop.
Before installing an Android package, open the install screen and compare the package name field against the name printed on the official download page.
Key points
Read the package name field
After tapping the file, the system dialog lists a package name like com.xxx.xxx. Compare it segment by segment with the official page.
Compare with the official line
Official download pages often print the package name under the file. Align both strings segment by segment; one extra segment means stop.
Check the signature digest
Some systems also show a signature digest. Compare its first characters with the digest published on the official page.
When unsure, do not install
If the package name mismatches and you cannot find it on the official page, delete the file and download again from the official site.
Common questions
The file name matches the official site, so why check the package name?
Because file names can be renamed freely, while the package name lives inside the file and cannot be changed by renaming.
Where can I see the package name?
On the system dialog that appears after you tap the install file, in the field labeled package name or app package.
