Android各路问题集锦

自从Google发布AS 3.0以来，一直都在犹豫要不要升级，要不要升级，要不要升级！昨天手贱升级了之后，呵呵哒！前方无数个坑慢慢爬吧，仅以记录自己遇到的关于AS 3.0来发过程中遇到的问题和解决方法。

1.错误如下

Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
Error:Execution failed for task ':app:mergeDebugResources'.
> Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

解决办法
在项目的gradle.properties中加入：

android.enableAapt2=false

2.关于library依赖

背景：
build.gradle(module:library)：

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

build.gradle(module:app)：

  buildTypes {
        release {
            signingConfig signingConfigs.myconfig
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        greendao {
            schemaVersion 2
        }
    }

原因：app中buildTypes集合不是library的buildTypes集合子集，即app中buildType属性greendao在依赖的library中找不到。
解决办法：
在build.gradle(module:library)增加greendao

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

        }
    }

3.关于多渠道打包错误

Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=xiaomiDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

之前的打包方式：

applicationVariants.all { variant ->
       variant.outputs.each { output ->
           def outputFile = output.outputFile
           if (outputFile != null && outputFile.name.endsWith('.apk')) {
               File outputDirectory = new File(outputFile.parent);
               def fileName
               if (variant.buildType.name == "release") {
                   fileName = "app_v${defaultConfig.versionName}_${releaseTime()}_${variant.productFlavors[0].name}.apk"
               } else {
                   fileName = "app_v${defaultConfig.versionName}_${releaseTime()}_debug.apk"
               }
               output.outputFile = new File(outputDirectory, fileName)
           }
       }
   }

修改成下面的方式：

applicationVariants.all { variant ->
    variant.outputs.all {
        if (variant.buildType.name == "release") {
            outputFileName = "app_v${defaultConfig.versionName}_${releaseTime()}_${variant.productFlavors[0].name}.apk"
        } else {
            outputFileName = "app_v${defaultConfig.versionName}_${releaseTime()}_debug.apk"
        }
    }
}

4.错误如下

Error:Execution failed for task :app:processDebugAndroidTestResources.
> No slave process to process jobs, aborting

解决办法
clean和rebuild都没有成功后，直接点击 File>Invalidate Caches/Restart后编译通过

5.错误如下

Error:(12, 32) 错误: 程序包android.support.multidex不存在

解决办法
在build.gradle文件里加上compile 'com.android.support:multidex:1.0.1'即可

6.错误如下

Error:Execution failed for task ':app:preDebugAndroidTestBuild'.
> Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved 
versions for app (26.1.0) and test app (27.1.1) differ. 
See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

解决办法

android {
    ...
}
configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
}
dependencies {
    ...
}

7.错误如下

Vivo Oppo系列手机运行安装总是失败

Failure [INSTALL_FAILED_TEST_ONLY]

解决办法

在该处加入

...
#解决Vivo手机安装失败问题
android.injected.testOnly=false

8.全面屏适配

//在Manifest的application节点加入属性
<application
    ...
    android:resizeableActivity="true"
    tools:targetApi="n"
    .../>

...
  <!--适配全面屏手机-->
  <meta-data android:name="android.max_aspect"
             android:value="2.1"/>
...

9.依赖

错误如下

Error: Could not find common.jar (android.arch.core:common:1.0.0).
       Searched in the following locations:https://jcenter.bintray.com/android/arch/core/common/1.0.0/common-1.0.0.jar

解决办法 将google()放在最前面

  allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
}

10.导入项目错误

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> More than one file was found with OS independent path 'META-INF/DEPENDENCIES'

解决办法

android {
    ...
       packagingOptions {
              exclude 'META-INF/LICENSE'
              exclude 'META-INF/DEPENDENCIES'
    }
    ...
}
