Android應用程序崩潰在Nougat

Question

上午剛剛安卓開發。在Android Studio 2.2和Android版本6.0中創建了一個應用程序。現在剛更新到android studio 2.3。它不適用於我的手機。

的build.gradle

android { 
    compileSdkVersion 24 
    buildToolsVersion '25.0.0' 
    defaultConfig { 
     applicationId "payment.online.rely.latitude"

      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Answer 1

快速suggesti on會是：你正在使用構建工具版本25和你的依賴和編譯器sdk使用版本24.你可以檢查是否解決？

您試圖訪問無效索引位置的列表中，你應該確認它是否試圖使用它之前的有效指標。

Answer 2

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.0' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

您應該更改類路徑版本。
