J'ai essayé le fichier C comme Cpp et utilisé extern « C » de toutes les manières possibles pas de résultat. J'ai également supprimé les dossiers bin, out, libs et obj à plusieurs reprises et nouvellement construit. Les compilations de code et les fichiers .so sont faits.

Mais je ne peux pas courir c'est le journal

Pour une raison quelconque la méthode n'est pas vu, et la bibliothèque chargement .... pour ce que ça vaut, j'edited ce code de here et a sorti ce dont j'avais besoin. Thanx

Exécutez ndk-build -b V = 1 et collez la sortie, le problème est probablement dans la création/liaison de la bibliothèque qui contient convertir. –

Dans le fichier source vous avez:

Java_com_myproject_ndk_convert

Mais le javah a:

Java_com_myproject_MainActivity_convert

Le journal dit aussi:

No implementation found for native Lcom/myproject/MainActivity;.convert:

Vouliez-vous écrire:

Java_com_myproject_MainActivity_convert

Merci pour avoir signalé cela.J'ai copié la mauvaise info .... mais maintenant j'ai modifié la question. Reste l'erreur –
