Question

我是新的Android工作室。我创建了一个Java项目，主要使用SQLite数据库（在资源文件夹中）。我将此项目从netbeans迁移到android studio。当我按下run并选择一个模拟器时，Gradle Build Tasks开始执行并出现错误，其中包含：

    * What went wrong:
   Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
   > java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

   * Try:
   Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

   * Get more help at https://help.gradle.org

   BUILD FAILED in 39s

控制台中的完整错误输出显示：

    :app:preDebugBuild UP-TO-DATE
    :app:compileDebugAidl UP-TO-DATE

这是按下＆＃39; run＆＃39;

后的堆栈跟踪

执行任务：[：app：assembleDebug]

multiDexEnabled true

网上有很多解决方案，例如gradle.build放在我已经拥有的apply plugin: 'com.android.application' android { compileSdkVersion 26 defaultConfig { applicationId "com.example.bcosta.myapplication" minSdkVersion 23 targetSdkVersion 23 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" multiDexEnabled = true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support.constraint:constraint layout:1.0.2' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' }文件中。

更新这是我的gradle.build文件

RewriteEngine On
RewriteRule ^([^_]*)_([^_]*)\.html$ /?s=scheda&id=$1&slug=$2 [L]
RewriteRule ^([^/]*)\.html$ /?s=$1 [L]

Answer 1

试试这个，

Service.startForeground(int, android.app.Notification)

如果您没有自定义Application类，请将此行添加到android { defaultConfig { ... multiDexEnabled true } } dependencies { compile 'com.android.support:multidex:1.0.1' }

manifest

如果您已拥有自己的Application类，请将其扩展为<application android:name="android.support.multidex.MultiDexApplication" .....your code而不是android.support.multidex.MultiDexApplication

android.app.Application

Answer 2

这似乎是一个没有确定解决方案的常见问题。

尝试：

删除.gradle目录。
清理项目并重新构建。

如果这不起作用，请尝试将以下内容添加到build.gradle：

android {
dexOptions{
   jumboMode=true;
   javaMaxHeapSize "4g"
}
}

另外，尝试文件 - ＆gt;使高速缓存/重新启动无效

Android Studio Gradle Build Error无法合并dex
