Espero haber proporcionado alguna información importante

Si alguien sabe algo ... por favor, ¡ayúdame! No puedo encontrar nada en este "NEULAND"

Perdón por la larga pregunta ... Gracias a todos los que han hecho las paces aquí.

EDITAR:

Actualicé las dependencias a:

compile ''org.apache.logging.log4j:log4j-core:2.5''
compile ''org.slf4j:slf4j-api:1.7.21''
compile ''org.slf4j:slf4j-log4j12:1.7.21''

Pero nada ha cambiado Todavía tengo unos 500 errores de compilación ... Eliminé MindPipe como referencia y lo codifiqué solo ... ¡No pasó nada!

Después de desinstalar Android Studio 2.0 e instalar 1.5.1 nuevamente, recibo la siguiente advertencia:

Advertencia: se requiere la versión 2.10 de Gradle. La versión actual es 2.8. Si usa el envoltorio gradle, intente editar el distributionUrl en C: / Sources / iRecyApps / iRecyMulco-1.0.1iOS / gradle / wrapper / gradle-wrapper.properties a gradle-2.10-all.zip

Entonces la versión gradle se actualizó por 2 ...

Me informé acerca de la versión gradle actual y es 2.12

Descargué ambos y probé esto:

Necesita cambiar Archivo> Configuraciones> Compilaciones, Ejecución, Despliegue> Herramientas de compilación> Gradle> Ruta de inicio de Gradle

En Mac OS, cambie la ruta en Android Studio> Preferencias> Compilaciones, Ejecución, Despliegue> Herramientas de compilación> Gradle> Gradle home

O configure Use el envoltorio gradle predeterminado y edite los archivos Project / gradle / wrapper / gradle-wrapper.properties field distributionUrl como este

de acuerdo a:

"Se requiere la versión Gradle 2.10". Error

http://tools.android.com/tech-docs/new-build-system/version-compatibility

Aún nada

Answer 1

Agregue esta línea a proguard-rules.pro

-keepattributes EnclosingMethod

Este error puede ocurrir casi en todas las clases que tienen InnerClasses, creo. (como support.v4 etc) para mí.

Lo probé en el estudio 2.2 de Android
(No probado log4j. Probado support.v4 etc.)

build.gradle

compileSdkVersion 24
buildToolsVersion "24.0.2"
...
minifyEnabled true
proguardFiles getDefaultProguardFile(''proguard-android.txt''), ''proguard-rules.pro''
...
dependencies {
    ...
    compile ''com.android.support:support-v4:24.2.1''
}

getDefaultProguardFile(''proguard-android-optimize.txt'') también funciona.

Answer 2

En mi caso, me encontré con este error cuando habilité Instant Run , pero después de desactivar Instant Run , el error desapareció.

Answer 3

Esto funcionó para mí, iniciar un nuevo proyecto de estudio de Android copiar y pegar gradle-wrapper.properties y build.gradle (Proyecto: "Nombre del proyecto") en su proyecto anterior que tuvo el error - para actualizar su gradle

También agregue esto en su proguard-rules.pro

-keepattributes EnclosingMethod

Actualice su build.gradle (Módulo: aplicación) de la siguiente manera

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(''proguard-android.txt''), ''proguard-rules.pro''
        }

    }

    dexOptions {
        preDexLibraries = false
    }

Answer 4

Se resolvió degradando todas las dependencias de com.android.support a 23.1.1 en la configuración de Gradle.

Answer 5

Yo también estaba enfrentando el mismo error. Me estaba volviendo loco porque el recuento de errores fue> 1K. Y estaba obteniendo estos errores en la versión de lanzamiento con proguard habilitado.

Después de investigar un poco, descubrí que al agregar -keepattributes EnclosingMethod en su archivo proguard-rules.pro , todos estos errores desaparecerán.

Fuente : Thread and Issue # 294 en GitHub.

Answer 6

Escriba este fragmento de código en proguard-rules.pro en su proyecto.

-keepattributes EnclosingMethod

Al escribir el fragmento anterior en el archivo proguard-rules.pro, las reglas de proguard en realidad cambian la forma en que las clases se ofuscan.
