Qualcuno mi aiuti per favore.

Answer 1

Questo di solito accade quando si richiama NDK-build da diretory errato. Devi essere nella cartella che contiene la sottodirectory jni.

Oppure, in alternativa fare ciò che il messaggio di errore ti dice - specificare NDK_PROJECT_PATH per correggere cartella.

Answer 2

1. Vai a/build/core
2. Modificare il NDK_PROJECT_PATH al percorso del progetto app
3. Aprire terminale
4. Vai al progetto cartella
5. Eseguire il NDK_BUILD

Answer 3

1. Vai la cartella principale ndk dal terminale

2. Digitare il comando con il percorso del progetto

   ndk-build -C your_project_path 
   

questo risolverà il problema. Se volete maggiori informazioni su "NDK-build" di comando è sufficiente digitare il comando

ndk-build --help 

Answer 4

è necessario dichiarare il percorso della posizione durante l'esecuzione del comando di NDK-build
1. cd
2. ndk- build NDK_PROJECT_PATH =

Answer 5

Questo potrebbe risolversi come segue: Ho affrontato lo stesso problema. Stavo lavorando a un'applicazione di riconoscimento del testo.

1- You should go the directory of your folder (which is inside the AndroidStudioProjects - "YOUR PROJECT", 

2- There should be a jni (Java Native interface) folder. Search for this folder. whenever, this is found. 

3- cd in cmd to that folder (The Parent folder of jni). 

4- run **ndk-build**
