解決できませんでした：com.android

Question

Androidスタジオ3.0の問題に直面しています。私はWindows 7 - 64ビットを使用しています。

私は自分の携帯電話に私のアプリを起動したいときはいつでも、それがクラッシュします。だから私はそれをGoogle検索すると、私は、バージョンの不一致がある可能性があるので、私はbuild.gradleファイルにいくつかの変更を適用したことを知った。変更と少しのデバッグの後、私はこのエラーを解決することができませんでした。

apply plugin: 'com.android.application' 

allprojects { 
    repositories { 
     jcenter() 
     google() 
    } 
} 

android { 
    compileSdkVersion 26 
    buildToolsVersion "26.0.2" 
    defaultConfig { 
     applicationId "com.planner.reemshams.projectplannerpro" 
     minSdkVersion 17 
     targetSdkVersion 26 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
}) 
    compile 'com.android.support:appcompat-v7-26+' 
    compile 'com.android.support.constraint:constraint-layout:1.0.2' 
    compile 'com.android.support:recyclerview-v7-24+' 
    compile 'com.android.support:cardview-v7-26+' 
    testCompile 'junit:junit:4.12' 
    implementation 'com.android.support:design-v7-26+' 
} 

編集：私は、アプリを実行している/構築しようとしたとき、私はMessagesタブで次しまった

Error: Failed to resolve: com.android

次は私のMyProject/app/build.gradleファイルです。

最新のGradleリリース versionあなたは、動的依存関係を使用しないようなので、最新のバージョン番号を使用して依存関係を置き換える必要で述べたように

Answer 1

26+または24+で終わる礼拝堂では働かないでください。バージョンを指定する必要があります。このコードを試してください、それは正常に動作します（私はそれをテストしました）

apply plugin: 'com.android.application' 


allprojects { 
    repositories { 
     jcenter() 
     google() 
    } 
} 

android { 
    compileSdkVersion 26 
    buildToolsVersion "26.0.2" 
    defaultConfig { 
     applicationId "com.planner.reemshams.projectplannerpro" 
     minSdkVersion 17 
     targetSdkVersion 26 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    implementation fileTree(include: ['*.jar'], dir: 'libs') 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    implementation 'com.android.support:appcompat-v7:26.1.0' 
    implementation 'com.android.support.constraint:constraint-layout:1.0.2' 
    implementation 'com.android.support:recyclerview-v7:26.1.0' 
    implementation 'com.android.support:cardview-v7:26.1.0' 
} 

Answer 2

：

compile 'com.android.support:appcompat-v7-26+' 
    compile 'com.android.support.constraint:constraint-layout:1.0.2' 
    compile 'com.android.support:recyclerview-v7-24+' 
    compile 'com.android.support:cardview-v7-26+' 
    implementation 'com.android.support:design-v7-26+' 

次にあなたがこのthreadに従うことができ、ここで私は、このエラーを解決しました言及されたステップで。その後も解決されない場合は、ターミナルウィンドウからlogcatを貼り付けてください。私はここでお手伝いします。

ありがとうございました。

Answer 3

コードは決して働いてはいけません。依存関係が正しくありません。

implementation 'com.android.support:appcompat-v7-26.+' 
implementation "com.android.support:recyclerview-v7-26.+" 
implementation "com.android.support:design-26.+" 

は、それがクラッシュし、そのアンドロイドのバージョンは何で、どのデバイスで

implementation 'com.android.support:appcompat-v7:26.+' 
implementation "com.android.support:recyclerview-v7:26.+" 
implementation "com.android.support:design:26.+"
