Échec de la vérification de dex: type de descripteur de méthode incorrect 7
J'essaie de créer un exemple de test dans lequel le contenu d'un TextView est défini sur le contenu d'un fichier stocké dans l'IPFS.
J'utilise ce référentiel pour mes fonctions: https://github.com/ipfs/Java-ipfs-api
Je continue à avoir ce qui semble être une erreur multidex despit activer multidex à plusieurs endroits:
defaultConfig {
applicationId "*****"
minSdkVersion 26
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "Android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
**multiDexEnabled true**
}
dependancies{
implementation 'com.Android.support:multidex:1.0.0'
}
MainActivity.Java:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
C'est l'erreur que j'obtiens:

c'est mon code:
TextView example = view.findViewById(R.id.example);
IPFS ipfs = new IPFS("/ip4/127.0.0.1/tcp/4001");
try {
ipfs.refs.local();
NamedStreamable.ByteArrayWrapper file = new NamedStreamable.ByteArrayWrapper("hello.txt", "G'day world! IPFS rocks!".getBytes());
MerkleNode addResult = ipfs.add(file).get(0);
Multihash filePointer = Multihash.fromBase58("QmPZ9gcCEpqKTo6aq61g2nXGUhM4iCL3ewB6LDXZCtioEB");
byte[] fileContents = ipfs.cat(filePointer);
this.example.setText(new String(fileContents));
} catch (IOException e) {
e.printStackTrace();
}
Edit: Je ne rencontrais pas cette erreur avant d’installer jitpack et Java-ipfs-api
Votre code n'a pas d'importance. L'erreur est " Impossible d'ouvrir les fichiers dex [...] Type de descripteur de méthode incorrect 7 ".
MethodHandleType est défini dans art/libdexfile/dex/dex_file.h
enum class MethodHandleType : uint16_t { // private
kStaticPut = 0x0000, // a setter for a given static field.
kStaticGet = 0x0001, // a getter for a given static field.
kInstancePut = 0x0002, // a setter for a given instance field.
kInstanceGet = 0x0003, // a getter for a given instance field.
kInvokeStatic = 0x0004, // an invoker for a given static method.
kInvokeInstance = 0x0005, // invoke_instance : an invoker for a given instance method. This
// can be any non-static method on any class (or interface) except
// for “<init>”.
kInvokeConstructor = 0x0006, // an invoker for a given constructor.
kInvokeDirect = 0x0007, // an invoker for a direct (special) method.
kInvokeInterface = 0x0008, // an invoker for an interface method.
kLast = kInvokeInterface
};
Par conséquent, dans votre cas, vous pouvez voir que l’une de vos méthodes est un invocateur pour une méthode directe (spéciale) (je suppose qu’elle se réfère à DMH ). Il a été ajouté dans commit 631827d .
À ce stade, je me demande si vous ne rencontrez pas de bogue dans le support technique de Java 8; car on ne s'attend pas à ce que quelque chose qui est désucré avec succès dans un dex ne s'exécute pas dans la technique.
Je viens de rencontrer le même problème, car certaines bibliothèques utilisent les fonctionnalités de Java 8; dans votre cas, il devrait s'agir de Java-ipfs-api. Pour résoudre le problème, configurez Android Gradle Plugin pour prendre en charge Java 8 en ajoutant le code suivant à votre fichier build.gradle. Assurez-vous d'utiliser le dernier plug-in Android Gradle:
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
