Come impostare NDK_MODULE_PATH in Android Studio e/o gradle?

Question

Sto eseguendo la migrazione di una libreria Android da Eclipse ad Android Studio. In Eclipse, potrei impostare NDK_MODULE_PATH tramite Progetto> Proprietà> Risorsa> Risorse collegate> Variabili del percorso. Ma come ottengo la stessa cosa in Android Studio, rispettivamente con gradle?

La mia libreria viene creata fino a quando non tenta di trovare le intestazioni per un modulo in NDK_MODULE_PATH.

Ecco il messaggio di errore:

Tutte le idee su questo?

Answer 1

Nella radice del progetto Android Studio, è presente un file denominato "local.properties". Aggiungi una proprietà denominata "ndk.dir" e imposta il valore in modo che punti alla posizione del ndk. Qualcosa come il seguente:

ndk.dir=/Users/username/sdk 

Forse non capisco la tua domanda. Se hai già impostato la posizione del ndk e vuoi solo assicurarti che un modulo venga creato, aggiungi il modulo al file "settings.gradle".

include ":<your module name>" 

quindi assicurarsi che si inserisce il codice C in "src/main/JNI" nel modulo. Gradle lo troverà automaticamente in base al nome della cartella. Non è più necessario impostare NDK_MODULE_PATH.

Answer 2

Usando: versione

• Gradle: 3.3
• Android versione plugin: com.android.tools.build:gradle:2.3.1

Questo funziona per me:

android { 

    ... 

    defaultConfig { 

     ... 

     ndk { 
      abiFilters 'armeabi', 'armeabi-v7a' 
     } 

     externalNativeBuild { 
      ndkBuild { 
       // TODO replace jniDependencies folder with the path to your modules 
       arguments "NDK_MODULE_PATH:=${rootProject.projectDir}/jniDependencies" 
      } 
     } 
    } 

    externalNativeBuild { 
     ndkBuild { 
      path 'src/main/jni/Android.mk' 
     } 
    } 


} 

In questo modo non è necessario aggiungere NDK_MODULE_PATH al mio PERCORSO per creare il progetto. Tuttavia, il compito pulito non riesce, perché non prenderanno l'argomento da qui, quindi ho bisogno di aggiungere un altro hack per risolvere questo:

tasks.withType(com.android.build.gradle.tasks.ExternalNativeCleanTask) { 
    it.actions.clear() 

    doLast { 
     project.delete("${projectDir}/.externalNativeBuild") 
    } 
}
