I met this problem before

Option 1

Delete the directory of the package name of the application under the data/data/directory, such as: ADB shell RM – RF data/data/com.demo.helloworld/

Then restart the phone

Or just turn off instant run

When the new version of Android studio runs APK, delete appears_ FAILED_ INTERNAL_ Error, error while installing apks
there is a way: open settings and find build > Instant run, remove the tick on the right and try to install again

Option 2:

Step 1: delete the existing APK with the same package name, such as ADB shell RM system/APP/outdoormeter/outdoormeter.apk

Step 2: delete the directory of the package name of the application under the data/data/directory, such as: ADB shell RM – RF data/data/com. Runbo. Outdoormeter/

Step 3: restart the Android mobile ADB reboot

Step 4: re install the APK
