Failed to compile resources with the following parameters:

解决方案:
可能是jdk版本低了，使用jdk8解决。

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

CommandInvokationFailure: Failed to re-package resources.

"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

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

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

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

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。

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）
