Looks like you need to modify your AndroidManifest xml Change android testOnly  true  to android testOnly  false  or remove this attribute   If you want to keep the attribute android testOnly as true you can use pm install command with -t option  but you may need to push the apk to device first     adb push bin hello apk  tmp  5210 KB s  825660 bytes in 0 154s     adb shell pm install  tmp hello apk      pkg   tmp hello apk Failure  INSTALL FAILED TEST ONLY     adb shell pm install -t  tmp hello apk      pkg   tmp hello apk Success   I was able to reproduce the same issue and the above solved it   If your APK is outside the device  on your desktop   then below command would do it     adb install -t hello apk

Android studio 3 0 generates test only APK   I have solved the issue by adding the  android testOnly  property to android manifest s  tag      lt application               android testOnly  false      android theme   style AppTheme  gt    And then generated the APK by Android studio3 0 menu Build-- Build APK s    More Info  https   commonsware com blog 2017 10 31 android-studio-3p0-flag-test-only html

My finding is as below  If I compile using the Android Studio UI  and the APK generated  I can t just   adb install  lt xxx apk gt    It will generate Failure  INSTALL FAILED TEST ONLY   I need to compile it using the gradle i e    gradlew app assembleRelease  Then only the generated apk  then it can only be installed   This is because the Android Studio UI Compile  only generate test apk for a particular device  while   gradlew app assembleRelease command is the actual apk generation to be installed on all device  and upload to playstore

I don t know if it s gonna be useful for anyone or not  but I got this error message  when I accidentally tried to build and install my project with test gradle plugin   gradle 2 4 0-alpha5   version in stable Android Studio version  2 3  not in 2 4 preview 5 version I d downloaded and installed before    When I realized my mistake  I launched preview Android Studio version and it built and installed my project without any problem

As mentioned in documentation      Android Studio automatically adds this attribute when you click Run   So  to be able to install your apk with adb install  lt path to apk file gt  you need to assemble build from terminal    gradlew assembleDebug and install with adb  Or just run   gradlew installDebug to build and install on the device simultaneously

None of the previous post solve my issue  Here is what s happening with me  I normally load the app from android studio by clicking on the  quot Run quot  button  When you do this  android would create an app that s good for debug but not for install  If you try to install using  adb install -r yourapk you will get a message that says  Failure  INSTALL FAILED TEST ONLY  When this happens  you will need to rebuilt the apk by first clean the build  then select Build- gt Build APK  See the image bellow   This APK is ready to be installed either through adb install command or any other methods Hope this helps David

I see the accepted answer  but  you dont have to actually  push the apk and then run the  command on adb shell  direct  adb install with -t flag  actually works     adb install -t  path to apk in ur  computer    attaching a screenshot for reference

The easiest to solve this  without reverting to an older gradle version is to add the  -t  option in the run configurations  for pm install    testOnly  false  had no effect whatsoever  The error is caused by the alpha version of gradle plugin that makes debug APK  for test only purposes   The -t option allows such APK to be installed  Setting it in run configuration makes it automatically install you APK as usual

I had a similar problem with Android Studio 3 0 0 Beta 7 and could not publish anymore to the play store   As stated here  https   developer android com studio run index html     Note  The Run  button builds an APK with testOnly  true   which means   the APK can only be installed via adb  which Android Studio uses   If   you want a debuggable APK that people can install without adb  select   your debug variant and click Build   Build APK s     Same goes for release build  with Android Studio 3 you need to go to Build  gt  Build APK s  to have a non testable release apk that you can submit to the store

Build your distribution  apk from Android Studio as follow  Build --  Build Apk s    for unsigned build   Build --  Generate Signed APK    for signed build   These option builds the APK with android testOnly  false  option which allows you to install the APK expicitly into device by the commond   adb install yourBuilT apk

Although I am sure Saurabh s answer will work for most other people  I did want to identify the extra steps I had to take in order to get my apk installed   I tried pushing to the device with the following result     adb push AppClient TestOnly App3 apk  tmp  failed to copy  AppClient TestOnly App3 apk  to   tmp    Read-only file system   After looking around to change the filesystem RW permissions I ended up executing the following commands     adb shell 255 shell android     su shell android     mount -o remount rw   mount -o remount rw     I got this when I tried to push again     adb push AppClient TestOnly App3 apk  tmp failed to copy  AppClient TestOnly App3 apk  to   tmp   Permission denied   I was able to  push to the sdcard     adb push AppClient TestOnly App3 apk  sdcard  3178 KB s  99747 bytes in 0 030s    At which point I was able to execute Saurabh s command   shell android     pm install -t  sdcard AppClient TestOnly App3 apk pm install -t  sdcard AppClient TestOnly App3 apk         pkg   sdcard AppClient TestOnly App3 apk Success
