Unity打Android包报错总结 长期更新

报错1 

Failed to compile resources with the following parameters:

-bootclasspath "E:\software\Android\AndroidSDK_ForUnity5\platforms\android-24\android.jar" -d "D:\h5\UnityProjects\IceClimber\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding UTF-8 "android\support\customtabs\R.java" "android\support\graphics\drawable\R.java" "android\support\graphics\drawable\animated\R.java" "android\support\v4\R.java" "android\support\v7\appcompat\R.java" "android\support\v7\cardview\R.java" "com\facebook\R.java" "com\facebook\android\R.java" "com\herofun\iceclimber\R.java"

解决方案: 

可能是jdk版本低了，使用jdk8解决。

报错2

解决方案

删除aar中的libs/classes.jar

报错3 

Error: [Temp\StagingArea\AndroidManifest-main.xml:12, 

D:\h5\UnityProjects\Test\AARTest\Temp\StagingArea\android-libraries\app-debug\AndroidManifest.xml:3] 

Main manifest has <uses-sdk android:minSdkVersion='9'> but library uses minSdkVersion='15'

UnityEditor.HostView:OnGUI()

解决方案

在Unity的PlayerSetting中把minSdkVersion设成与第三方库中的minSdkVersion一致

报错4 

CommandInvokationFailure: Failed to re-package resources.

E:\software\Android\AndroidSDK_ForUnity5\build-tools\24.0.1\aapt.exe package

 --auto-add-overlay -v -f -m -J "gen" -M "AndroidManifest.xml" -S "res" -I 

 "E:\software\Android\AndroidSDK_ForUnity5\platforms\android-25\android.jar" 

 -F bin/resources.ap_ --extra-packages com.zwwx.game.gamesupport -S 

 "D:\h5\UnityProjects\Test\AARTest\Temp\StagingArea\android-libraries\app-debug\res"

错误原因

build-tools用的版本是24，platforms版本用的是android-25, 两个版本不一致导致报错。

解决方案

使用platforms/android-24打包

报错5 

CommandInvokationFailure: Unable to merge android manifests. See the Console for more details. 

E:\software\Java\jdk8\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir="E:\software\Android\AndroidSDK_ForUnity5\tools" -Dfile.encoding=UTF8 -jar "E:\software\Unity5_5\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -

stdout[

Warning: [Temp\StagingArea\AndroidManifest-main.xml:12, 

D:\h5\UnityProjects\Test\AARTest\Temp\StagingArea\android-libraries\app-debug\AndroidManifest.xml:3] 

Main manifest has <uses-sdk android:targetSdkVersion='23'> but library uses targetSdkVersion='25'

]

错误原因

第三方库与Unity中用的SDK的targetSdkVersion版本不一致。

解决方案

Unity使用targetSdkVersion='25'打包。

Android SDK升级到以下版本

platforms/android-25、tools_r25.2.5-windows、build-tools_r25.0.2-windows

注意：最新版本的tools下没有android.bat命令，打包会报Error:Invalid command android错误

报错6 

CommandInvokationFailure: Unable to list target platforms.Please make sure the android sdk path is correct. See the Console for more details. 

E:\software\Java\jdk8\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir="E:\software\Android\AndroidSDK\tools" -Dfile.encoding=UTF8 -jar "E:\software\Unity5_5\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -

stderr[

Error:Invalid command android

]

错误原因

新版本的tools下没有android.bat命令，所以打包时报Error:Invalid command android

解决方案

下个旧版本的tools再打包。tools_r25.2.5-windows.zip

报错7 

UnityException: Adding Android library projects failed!

UnityEditor.Android.AndroidLibraries.AddLibraryProject (System.String projectPropertiesPath)

UnityEditor.Android.AndroidLibraries.FindAndAddLibraryProjects (System.String searchPattern)

UnityEditor.Android.PostProcessor.Tasks.AddAndroidLibraries.Execute (UnityEditor.Android.PostProcessor.PostProcessorContext context)

UnityEditor.Android.PostProcessor.PostProcessRunner.RunAllTasks (UnityEditor.Android.PostProcessor.PostProcessorContext context)

错误原因

aar中的某些文件被删除了，比如aar中的AndroidManifest.xml被删除了。

解决方案

重新生成个aar

报错8 

Error:Execution failed for task ':processReleaseGoogleServices'.

> No matching client found for package name 'com.zwwx.game.WinterJump'

原因：google-services.json中的包名与build.gradle中的包名不一致。

解决方案：改成一致就行了。

报错9 

用gradle build打包时报以下错 

To run dex in process, the Gradle daemon needs a larger heap.

It currently has 1024 MB.

For faster builds, increase the maximum heap size for the Gradle daemon to at le

ast 1536 MB.

To do this set org.gradle.jvmargs=-Xmx1536M in the project gradle.properties.

For more information see https://docs.gradle.org/current/userguide/build_environ

ment.html

原因：gradle需要更大内存 

解决方案: 修改gradle-wrapper.properties文件。 

在gradle-wrapper.properties文件中添加一条配置 

set  org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=2048m

报错10 

Parsing json file: D:\xxx\google-services.json

:processDebugGoogleServices FAILED

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':processDebugGoogleServices'.

> No matching client found for package name 'com.xx.xxx.xxxxx'

* Try:

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

原因：google-services.json中定义的包名与AndroidManifest.xml中定义的包名不一致。 

解决方案：包名改一致。

报错11

Rejecting re-init on previously-faile d class java.lang.Class<com.helpshift.support.adapters.QuestionListAdapter>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/widget/RecyclerView$Adapter;

解决方案: 删除libs下的android-support-v4.jar保留android-support-v7-appcompat.jar

报错12

CommandInvokationFailure: Unable to convert classes into dex format.

stderr[

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

我出现这个问题的时候下面的提示还没有看只看上面红字部分，说明jdk版本太低，我原来是1.7的换成1.8果断好使

报错13

Error:(26, 9) Attribute application@icon value=(@drawable/logo) from AndroidManifest.xml:26:9

Error:(28, 9) Attribute application@theme value=(@style/ThemeActionBar) from AndroidManifest.xml:28:9

is also present at XXXX-trunk:XXXXLib:unspecified:15:9 value=(@style/AppTheme)

Suggestion: add 'tools:replace="android:theme"' to <application> element at AndroidManifest.xml:24:5 to override

Error:Execution failed for task ':XXXX:processDebugManifest'.

> Manifest merger failed with multiple errors, see logs

原因：

AS的Gradle插件默认会启用Manifest Merger Tool，若Library项目中也定义了与主项目相同的属性（例如默认生成的android:icon和android:theme），则此时会合并失败，并报上面的错误。

解决方法有以下2种：

方法1： 在Manifest.xml的application标签下添加tools:replace="android:icon, android:theme"（多个属性用,隔开，并且记住在manifest根标签上加入xmlns:tools="http://schemas.android.com/tools"，否则会找不到namespace哦）

方法2： 在build.gradle根标签上加上useOldManifestMerger true （懒人方法）

报错14：

Library Project里面的 BuildConfig.DEBUG永远都是false 。这是Android Studio的一个已知问题，某Google的攻城狮说，Library projects目前只会生成release的包。

Issue 52962: https://code.google.com/p/android/issues/detail?id=52962

解决方法： （某Google的攻城狮推荐的方法）

Workaround: instaed of BuildConfig.DEBUG create another boolean variable at lib-project's e.g. BuildConfig.RELEASE and link it with application's buildType.

报错15：

每次保存的时候，每行多余的空格和TAB会被自动删除（例如结尾、空行的多余空格或TAB）

特别是每次准备提交SVN，Review代码时候你就蛋疼了，显示一堆不相关的更改，看的眼花。

解决方法：

Settings->IDE Settings->Editor->Other->Strip trailing spaces on Save->None

问题四：

编译的时候，报：Failure [INSTALL_FAILED_OLDER_SDK]。一般是系统自动帮你设置了compileSdkVersion 

解决方法：

修改build.gradle下的compileSdkVersion 'android-L'为compileSdkVersion 19（或者你本机已有的SDK即可）
