错误：Android Studio中不允许使用字符串类型（在“主题”中值为“”）

Question

When I run android studio, I keep getting this error:

:app:prepareComAndroidSupportAnimatedVectorDrawable2321Library UP-TO-DATE :app:preReleaseBuild UP-TO-DATE :app:checkDebugManifest :app:preDebugBuild UP-TO-DATE :app:preBuild UP-TO-DATE Information:BUILD FAILED :app:prepareComAndroidSupportDesign2321Library UP-TO-DATE :app:prepareComAndroidSupportAppcompatV72321Library :app:prepareComAndroidSupportSupportV42321Library UP-TO-DATE :app:prepareComAndroidSupportRecyclerviewV72321Library UP-TO-DATE :app:prepareComAndroidSupportSupportVectorDrawable2321Library UP-TO-DATE :app:prepareDebugDependencies :app:compileDebugAidl UP-TO-DATE :app:compileDebugRenderscript UP-TO-DATE :app:generateDebugBuildConfig UP-TO-DATE :app:generateDebugAssets UP-TO-DATE :app:mergeDebugAssets UP-TO-DATE :app:generateDebugResValues UP-TO-DATE :app:generateDebugResources UP-TO-DATE :app:mergeDebugResources UP-TO-DATE :app:processDebugManifest UP-TO-DATE :app:processDebugResources

C : \\Users\\User\\Desktop\\UniTools\\app\\build\\intermediates\\exploded- aar\\com.android.support\\appcompat-v7\\23.2.1\\res\\values\\values.xml

Error:(315, 5) String types not allowed (at 'theme' with value ''). Error:Execution failed for task ':app:processDebugResources'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\\Users\\User\\AppData\\Local\\Android\\sdk\\build-tools\\23.0.2\\aapt.exe'' finished with non-zero exit value 1

 <style name="Base.TextAppearance.AppCompat.SearchResult" parent="">
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">?android:textColorPrimary</item>
    <item name="android:textColorHint">?android:textColorHint</item>
</style>

Then Android Studio takes me this this code in the values.xml. Any ideas on what the problem is?

Answer 1

edit your 'values.xml' from the explorer: find values.xml->edit in notepad-> rebuild project.

you are trying to edit the generated file so parent="" appears again and again. because you cannot edit generated file

Answer 2

You assign empty value to 'theme'

I think 'theme' in styles.xml or you can search for 'theme' in xml files under 'values' folder.

then check what value you assigned for 'theme'

Answer 3

I had similar problems. To solve it just edit the values.xml file in notepad and save it, then you should be good-to-go. Go to build/intermediates/ress/merged/debug/values .
