Android Question [SOLVED] No signature found in package of version 2 or newer for package

[Jmu5667]

Hello

We are working with a phone manufacturer and they have supplied us with the signapk.jar, platform.x509.pem, platform.pk8 file so we can sign our app as a system app. In the manifest file of the app I have added SetManifestAttribute(android:sharedUserId, "android.uid.system").

The phone is running Android 11

I have a batch file to do the build:

REM EX710
"C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder.exe" -task=Build -obfuscate=True -BaseFolder="C:\Users\John Murphy\Documents\B4A\Atlas\SOS\working" -Configuration=ex710_system -Output=atlas_sos4.apk
copy "C:\Users\John Murphy\Documents\B4A\Atlas\SOS\working\Objects\atlas_sos4.apk" "C:\Users\John Murphy\Documents\B4A\Atlas\SOS\ex710 signapk"

cd \
cd "C:\Users\John Murphy\Documents\B4A\Atlas\SOS\ex710 signapk"
java -jar signapk.jar platform.x509.pem platform.pk8 atlas_sos4.apk atlas_sos4_ex710.apk
copy "C:\Users\John Murphy\Documents\B4A\Atlas\SOS\ex710 signapk\atlas_sos4_ex710.apk" "C:\Users\John Murphy\Documents\B4A\Atlas\SOS\working\Output"

pause

The build is succuessful. I then copy the atlas_sos4_ex710.apk to the phone download folder, and using the file explorer on the phone select it to install. I am asked the usual 'Do you want to install this application?', I select install, and I get a message saying 'You can't install the app on your device'.

The target SDK in the manfest is set to 30.

The following is from the unfiltered logs for the phone. Two things to notice in the logs, #1-Malformed package, #2-No signature found in package of version 2 or newer for package com.is.vitllinkSOS

Does anyone have any ideas solutions for this.

Two things to notice in the logs, #1-Malformed package, #2-No signature found in package of version 2 or newer for package com.is.vitllinkSOS

The tool signapk is the version 2 signature tool. According to Android documentation, one has to zipalign the apk before signing it. Try zipalign-ing the APK before signing it and then see if the malformed package and version issue goes away:
