Kann RecyclerView nicht zu API Level 19 hinzufügen

Question

Ich versuche RecyclerView zu einem Projekt hinzuzufügen, das ich geerbt habe, das gegen API 19 kompiliert wurde und nicht höher gehen kann.

Nachdem ich hinzufügen RecylerView von der Support-Bibliothek wie folgt aus:

compile 'com.android.support:recyclerview-v7:+' 

Das Projekt nicht mehr bauen, beginnt es multidex Ausnahmefehler wie diese geben:

Error:Execution failed for task ':app:transformClassesWithDexForDevDebug'. 
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_91\bin\java.exe'' finished with non-zero exit value 3 

dieses Problem zu beheben, ich habe folgendes getan

1. Aktivierte multidex unterstützung wie so multiDexEnabled true
2. hinzufügen compile 'com.android.support:multidex:1.0.1'
3. Installieren multidex in applciation Klasse wie folgt: MultiDex.install(this);

All dies half nicht. Hier ist die Abhängigkeiten Grafik von laufenden ./gradlew App: Abhängigkeiten

Und basierend auf der Grafik unten, welche Änderung muss ich machen, um das Projekt wieder aufzubauen? Hier

compiler that did not target the modern .class file format. The recommended 
solution is to recompile the class from source, using an up-to-date compiler 
and without specifying any "-target" type options. The consequence of ignoring 
this warning is that reflective operations on this class will incorrectly

Answer 1

Da Sie hinzufügen:

compile 'com.android.support:recyclerview-v7:+' 

Sie die 24.1.1 Version verwenden.
Die Supportbibliotheken v24 erfordern, dass API 24 kompiliert wird.

android { 
    compileSdkVersion 24 
    //... 

} 

können Sie another version des RecyclerView verwenden, aber die erste Version war 21.0.0 die API21 erfordert.

Answer 2

Kann bauen und führen dies auf API 19 Gerät ohne Probleme und haben viele Ansichten mit RecyclerView.

Nimm davon was du willst. Wenn es nicht hilft, sorry.

build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "24.0.1" 

    defaultConfig { 
     applicationId "com.androidstack.app" 
     minSdkVersion 16 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
//  generatedDensities = [] 
    } 

    compileOptions { 
     sourceCompatibility JavaVersion.VERSION_1_7 
     targetCompatibility JavaVersion.VERSION_1_7 
    } 

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

    // This is handled for you by the 2.0+ Gradle Plugin 
    aaptOptions { 
     additionalParameters "--no-version-vectors" 
    } 
} 

ext { 
    // Variables to keep libraries consistent 
    supportLibrary = '23+' 

    // Support Libraries dependencies 
    supportDependencies = [ 
      design   :   "com.android.support:design:${supportLibrary}", 
      recyclerView  :   "com.android.support:recyclerview-v7:${supportLibrary}", 
      appCompatV7  :   "com.android.support:appcompat-v7:${supportLibrary}", 
    ] 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 

    // compile supportDependencies.recyclerView 

    // recommended instead - Includes themes, AppCompat libraries, and RecyclerView 
    compile supportDependencies.design 

}
