you are not running any emulators and you did not connected any physical device for USB debugging (see Run Apps on a Hardware Device).

And when i click on "Ok" show up that note: minSdk(API 16) > deviceSdk(API 14).

The emulator is running Android API 14 and your project's minSDK is 16 so your project will not run on devices/emulators < your project's minSDK (read this)

So either change your minSDK to 14 (if this is OK) or test on an device/emulator with SDK >= 16.

  • @saidbous as I mentioned, either change your `minSDK` to 14 (if this is OK) or test on an emulator with SDK >= 16 (create a new emulator with SDK >=16 ) – ATEF Apr 03 '17 at 23:34
  • @saidbous see [Changing API level Android Studio](http://stackoverflow.com/questions/19465049/changing-api-level-android-studio) if you want to change your minSDK – ATEF Apr 03 '17 at 23:36
  • After i create an other device with API 16...show up to me that msg: "Cannot launch AVD in emulator. Output: emulator: ERROR: This AVD's configuration is missing a kernel file! Please ensure the file "kernel-qemu" is in the same location as your system image. emulator: ERROR: ANDROID_SDK_ROOT is undefined start=(Button)findViewById(R.id.startb);" – Said Bousnane Apr 04 '17 at 00:10
