ADB in android studio doesn't install apk, what's the problem?

Question

Java

What is wrong or where is the problem?
On a computer or tablet?
Problems can be here and there, in a computer in Linux I could screw up, in android too (recently restored from backup).
Here is the log from the studio
Installing com.example.denis.myapplication
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.example.denis.myapplication"
pkg: /data/local/tmp/com.example.denis .myapplication
Failure [INSTALL_FAILED_INVALID_APK]
This is a new clean project, I tried it, there was an erroneous package, where and what to do?

Answer 1

check gradle file

Answer 2

Check the manifest, see if such an application (with such a package) is already on the device

Answer 3

1. Try to change the name of the package
2. Build the project and install it directly from Android, if this apk is not installed there, download any of w3bsit3-dns.com and try to install it, if the error is 80% that PackageInstaller.apk is located in / system / app
3 Try to install something that is not your own using adb install toster.apk, if the error is try point 2
4. If ADB works fine and everything is put on the android itself, look towards gradle and ide

Answer 4

I remember trying to put an apk for 4.3 on a device with android 4.1, the error was the same. Check android version in manifest.
