eclipse转Android studio遇到的那些坑 _Android

笛里谁知壮士心，沙头空照征人骨。这篇文章主要讲述eclipse转Android studio遇到的那些坑相关的知识，希望能为你提供帮助。
公司项目有导入10多个libray，还有涉及ndk，转android studio时碰到不少问题。前后大概花费5个工作日，中间各种奇葩bug，各种编译出错，非常多还有没错误提示。一度想过放弃，如不是没有选择，可能真要放弃了。最后成功转型还是非常值得的。现记录下遇到的问题，给有须要的人。 1.

解决：在manifest里面，某个activity下多写了一句intent-filter，里面没有内容，删了之后就没错误了。

错误例如以下：

解决：使用NDK时。NDK not configured

http://stackoverflow.com/questions/20674650/how-to-configure-ndk-with-android-gradle-plugin-0-7
在NDK libproject下的 build.gradle中加入

123456789101112 productFlavors { arm { ndk { abiFilters" armeabi"," armeabi-v7a" } } x86 { ndk { abiFilter" x86" } } }

或者

1234567 buildTypes { debug { ndk { abiFilters" armeabi"," armeabi-v7a" } } }

File > Settings > Build, Execution, Deployment > Compiler
and see " Command-line-options" and check if anything is give. (In your case -x). If so remove it and click Apply and Ok. Now restart your android studio and try building解决：配置错误把这里的配置删掉

4. > com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘C:\Program Files\Java\jdk1.7.0_51\bin\java.exe‘‘ finished with non-zero exit value 1 解决：电脑配置可能不够用，所以開始不断尝试改动占用内存相关的东西。并最终取得了进展。关键代码是build.gradle中的：

dexOptions 
{

 
  
 javaMaxHeapSize 
"
xx"

}xx为合理的内存大小（如4g）。假设你也遇到了这样的问题，最好还是试试~
5. Error:(24, 1) A problem occurred evaluating root project ‘MyApplication2‘.> Could not find method dexOptions() for arguments [[email protected]] on root project ‘MyApplication2‘. 解决：不能写成一行

dexOptions 
{

}

解决：改成相相应的版本 compile‘com.android.support:appcompat-v7:19.+ ‘

8. Error:Error: File path too long on Windows, keep below 240 characters : C:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\unspecified\res\drawable-xhdpi-v4\battle_navigation_button_signout_default.png 解决：把文件甲路径缩短

9. Error:Execution failed for task ‘:wonderDroid:processDebugAndroidTestManifest‘.
> java.lang.RuntimeException: Manifest merger failed : Attribute [email protected] value=https://www.songbingjia.com/android/(@style/Theme.Sherlock) from [debug] AndroidManifest.xml:22:9-46
is also present at [branch_20151216_1.5.0_01_copy:emuUtils:unspecified] AndroidManifest.xml:15:9-40 value=https://www.songbingjia.com/android/(@style/AppTheme). Suggestion: add ‘tools:replace=" android:theme" ‘ to < application> element at manifestMerger3943799027194821591.xml:7:5-9:19 to override.
解决方式：在Manifest.xml的application标签下加入tools:replace=" android:icon, android:theme" （多个属性用,隔开，而且记住在manifest根标签上加入xmlns:tools=" http://schemas.android.com/tools" ，否则会找不到namespace哦）參考：http://blog.csdn.net/codezjx/article/details/38669939
Suggestion: add ‘tools:replace=" android:theme" ‘ to < activity> element at AndroidManifest.xml:1120:9-1128:20 to override. 这个错误就是< activity> 合并时冲突了。和application一样，依据冲突提示加入就可以，如： < activity
tools :replace=" android:configChanges"
android :name=" xxxxx"
android:configChanges=" mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|fontScale|uiMode|screenSize|smallestScreenSize"
android :label=" @string/N64_Name"
android :process=" :game"
android :theme=" @style/appTheme.Black" > < /activity>
10. AAPT err(Facade for 1813194376): libpng error: Not a PNG file Error:Execution failed for task ‘:xxxx:mergeDebugResources‘. > Some file crunching failed, see logs for details 原因是jpg格式的图片后缀为png，AS校验严格，eclipse不校验使用美图工具将图片转为png图片

11. Error:Execution failed for task ‘:xxx:processDebugManifest‘. > F:\xxx\src\main\AndroidManifest.xml:329:9-335:20: Error: Invalid instruction ‘targetApi‘, valid instructions are : REMOVE,REPLACE,STRICT
解决： < activity
android :name=" xxxx"
android:configChanges=" mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|fontScale|uiMode|screenSize|smallestScreenSize"
android :label=" @string/app_name"
android :theme=" @android:style/Theme.Holo.Light.Dialog"
tools :targetApi=" 11" > < /activity> 把Manifest中tools:targetApi=" 11" 去掉

把定义的接口类单独提出来，不要写在类里面，不然会以为循环继承
13. Error:Execution failed for task ‘:xxxx:transformResourcesWithMergeJavaResForDebug‘. > com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/maven/com.squareup.okio/okio/pom.xml File1: xxx\libs\com.umeng.message.lib_v2.3.0.jar File2: xxx\build\intermediates\exploded-aar\xxx\unspecified\jars\classes.jar 友盟的sdk和其它jar冲突解决： 1）添加配置（好像没用） packagingOptions {
exclude ‘META-INF/NOTICE‘ // will not include NOTICE file
exclude ‘META-INF/LICENSE‘ // will not include LICENSE file } 2)更新友盟新的sdk
Error:Execution failed for task ‘:xxx:transformResourcesWithMergeJavaResForDebug‘. > com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/maven/com.squareup.okio/okio/pom.xml File1: C:\Users\Administrator\.gradle\caches\modules-2\files-2.1\com.squareup.okio\okio\1.2.0\c0b52915a48fa91b1b94a28d4a2997bac5f524df\okio-1.2.0.jar File2: xxx\build\intermediates\exploded-aar\branch_20151216_1.5.0_01_copy\emuUtils\unspecified\jars\classes.jar 解决：配置 packagingOptions { exclude‘META-INF/maven/com.squareup.okio/okio/pom.xml‘ exclude‘META-INF/maven/com.squareup.okio/okio/pom.properties‘ } 友盟推送sdk使用了okio包，我的项目libray中也调用了。合并时冲突。
我友盟pushsdk中的okio包去掉。引用libray就可以。

14. Error:Execution failed for task ‘:xxx:transformClassesWithDexForDebug‘. > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘C:\Program Files\Java\jdk1.8.0_73\bin\java.exe‘‘ finished with non-zero exit value 2 解决：主project和libray引用的包反复了,这个问题比較麻烦，因为项目中有10多个libray,要细致排插反复的jar。

15. 最终成功后，桌面出现多个图标解决：把每一个libray的配置MAIN删掉 < intent-filter>
< action android :name=" android.intent.action.MAIN" />
< category android :name=" android.intent.category.LAUNCHER" /> < /intent-filter> 16. 打包时出现的错误 Error:(2) Error: In Gradle projects, always use http://schemas.android.com/apk/res-auto for custom attributes [ResAuto] 解决： < ScrollViewxmlns:app=" http://schemas.android.com/apk/res/xx.xxx.xxx" xmlns:android=" http://schemas.android.com/apk/res/android" 改为： < ScrollViewxmlns:app=" http://schemas.android.com/apk/res-auto" xmlns:android=" http://schemas.android.com/apk/res/android"
