+
+To open project in **Android Studio** select **Import project (Gradle, Eclipse ADT, etc)**
+and  select `android` folder of the `espeak-ng` project.
+
+Then select menu **File — Project Structure...**, tab **SDK Location**, field **Android NDK location**
+and set your location of NDK, e.g. `/home/user/Android/Ndk`.
 
 ### Installing
 
 Now, you can install the APK using the `adb` tool:
 
-    $ adb install -r android/build/outputs/apk/espeak-release-signed.apk
+    $ adb install -r android/build/outputs/apk/release/espeak-release-signed.apk
 
 After running, `eSpeakActivity` will extract the `espeakdata.zip` file into its
 own data directory to set up the available voices.
