Use gradle task change activity attribute in AndroidManifest.xml

问题

我想在我的清单文件中为所有活动设置一个属性（android:configChanges="screenSize|smallestScreenSize|screenLayout"），并且我尝试的方式如下：

我已经在我的应用程序模块的build.gradle文件中添加了一些代码片段：

  1. android.applicationVariants.all { variant ->
  2.     print("check variant:${variant.getClass()}\n")
  3.     variant.outputs.each { output ->
  4.         print("check output all task:${output.getName()}\n")
  5.         def processorTask = output.processManifestProvider.getOrNull()
  6.         print("check processorTask:${processorTask.getName()}\n")
  7.         // ProcessApplicationManifest
  8.         // https://android.googlesource.com/platform/tools/base/+/studio-master-dev/build-system/gradle-core/src/main/java/com/android/build/gradle/tasks/ProcessApplicationManifest.java
  9.         processorTask.doLast { task ->
  10.             def directory = task.getBundleManifestOutputDirectory()
  11.             def srcManifestFile = "$directory${File.separator}AndroidManifest.xml"
  12.             print("check manifest file:$srcManifestFile\n")
  13.             def manifestContent = new File(srcManifestFile).getText()
  14.             def xml = new XmlParser(false, false).parseText(manifestContent)
  15.             print("check manifest application:${xml.application.size()}")
  16.             xml.application[0].activity.forEach{
  17.                 it.attributes().put('android:configChanges', 'screenSize|smallestScreenSize|screenLayout')
  18.             }
  19.             def serializeContent = groovy.xml.XmlUtil.serialize(xml)
  20.             def targetFile = new File(srcManifestFile)
  21.             targetFile.write(serializeContent)
  22.         }
  23.     }
  24. }

执行命令gradlew assembleDebug后，它会生成一个文件和一个apk文件。文件内容如下所示：

图片内容是我需要的，但生成的apk文件内容如下所示：

它丢失了在gradle任务中添加的属性。我想知道如何使它工作，请帮忙。

I want to set an attribue(android:configChanges="screenSize|smallestScreenSize|screenLayout") for all activities in my manifest file with gradle file,and what I'm trying like follow:
I had add some code snippet in my app module's build.gradle file :

  1. android.applicationVariants.all { variant ->
  2.     print("check variant:${variant.getClass()}\n")
  3.     variant.outputs.each { output ->
  4.         print("check output all task:${output.getName()}\n")
  5.         def processorTask = output.processManifestProvider.getOrNull()
  6.         print("check processorTask:${processorTask.getName()}\n")
  7.         //ProcessApplicationManifest
  8.         //https://android.googlesource.com/platform/tools/base/+/studio-master-dev/build-system/gradle-core/src/main/java/com/android/build/gradle/tasks/ProcessApplicationManifest.java
  9.         processorTask.doLast {task ->
  10.             def directory = task.getBundleManifestOutputDirectory()
  11.             def srcManifestFile = "$directory${File.separator}AndroidManifest.xml"
  12.             print("check manifest file:$srcManifestFile\n")
  13.             def manifestContent = new File(srcManifestFile).getText()
  14.             def xml = new XmlParser(false, false).parseText(manifestContent)
  15.             print("check manifest application:${xml.application.size()}")
  16.             xml.application[0].activity.forEach{
  17.                 it.attributes().put('android:configChanges', 'screenSize|smallestScreenSize|screenLayout')
  18.             }
  19.             def serializeContent = groovy.xml.XmlUtil.serialize(xml)
  20.             def targetFile = new File(srcManifestFile)
  21.             targetFile.write(serializeContent)
  22.         }
  24.     }
  25. }

After execute command gradlew assembleDebug it generates a file and an apk.File content like this picture

以下是已翻译的代码部分：

  1. project.afterEvaluate {
  2.     def variants = null
  3.     try {
  4.         variants = android.applicationVariants
  5.     } catch (Throwable t) {
  6.         try {
  7.             variants = libraryVariants
  8.         } catch (Throwable tt) {}
  9.     }
  10.     if (variants != null) {
  11.         variants.all { variant ->
  12.             variant.outputs.each { output ->
  13.                 def task = output.processManifestProvider.get()
  14.                 if (task == null) {
  15.                     return
  16.                 }
  17.                 task.doLast {

  19.                     if (manifestFile == null || !manifestFile.exists()) {
  20.                         return
  21.                     }
  22.                     def parser = new XmlParser(false, true)
  23.                     def manifest = parser.parse(manifestFile)
  24.                     def app = manifest.'application'[0]
  25.                     app.'activity'.each{act->
  26.                         String value = act.attributes()['android:configChanges']
  27.                         if (value == null) {
  28.                             value = "keyboardHidden|orientation|screenSize"
  29.                         } else {
  30.                             String[] valueSplit = value.split("\\|")
  31.                             if (!valueSplit.contains("keyboardHidden")) {
  32.                                 value+="|keyboardHidden"
  33.                             }
  34.                             if (!valueSplit.contains("orientation")) {
  35.                                 value+="|orientation"
  36.                             }
  37.                             if (!valueSplit.contains("screenSize")) {
  38.                                 value+="|screenSize"
  39.                             }
  40.                         }
  41.                         act.attributes()["android:configChanges"] = value
  42.                     }
  43.                     manifestFile.setText(XmlUtil.serialize(manifest), "utf-8")
  44.                 }
  45.             }
  46.         }
  47.     }
  48. }

请将此代码段添加到 app/build.gradle 的末尾。

英文:

After several days,I addressed this issue by my self,the correct way:

  1. project.afterEvaluate {
  2. def variants = null
  3. try {
  4. variants = android.applicationVariants
  5. } catch (Throwable t) {
  6. try {
  7. variants = libraryVariants
  8. } catch (Throwable tt) {}
  9. }
  10. if (variants != null) {
  11. variants.all { variant ->
  12. variant.outputs.each { output ->
  13. def task = output.processManifestProvider.get()
  14. if (task == null) {
  15. return
  16. }
  17. task.doLast {
  18. def manifestFile = new File(task.manifestOutputDirectory.get().getAsFile(),"AndroidManifest.xml")
  19. if (manifestFile == null || !manifestFile.exists()) {
  20. return
  21. }
  22. def parser = new XmlParser(false, true)
  23. def manifest = parser.parse(manifestFile)
  24. def app = manifest.'application'[0]
  25. app.'activity'.each{act->
  26. String value = act.attributes()['android:configChanges']
  27. if (value == null) {
  28. value = "keyboardHidden|orientation|screenSize"
  29. } else {
  30. String[] valueSplit = value.split("\\|")
  31. if (!valueSplit.contains("keyboardHidden")) {
  32. value+="|keyboardHidden"
  33. }
  34. if (!valueSplit.contains("orientation")) {
  35. value+="|orientation"
  36. }
  37. if (!valueSplit.contains("screenSize")) {
  38. value+="|screenSize"
  39. }
  40. }
  41. act.attributes()["android:configChanges"] = value
  42. }
  43. manifestFile.setText(XmlUtil.serialize(manifest), "utf-8")
  44. }
  45. }
  46. }
  47. }
  48. }

Add this code snippet into end of app/build.gradle.

Well,the above way is only for the situation which every element of activity is not include attribute android:configChanges or will got another question😂😂😂,I post it here.

Well again,🐶🐶🐶after several try,I fixed this problem by myself and I post correct answer in my another issue.

你可以使用清单占位符来解决：

  • 清单：

    1.   <activity
    2. android:name=".YourActivity"
    3. android:configChanges="${configChanges}">
    4. <intent-filter>
    5. <action android:name="android.intent.action.MAIN" />
    6. <category android:name="android.intent.category.LAUNCHER" />
    7. </intent-filter>
    8. </activity>

  • Gradle：

defaultConfig {manifestPlaceholders = [ configChanges:"orientation"]}

英文:

You can solve by using manifest placeholders:

  • Manifest:

    1.  <activity
    2. android:name=".YourActivity"
    3. android:configChanges="${configChanges}">          
    4. <intent-filter>
    5. <action android:name="android.intent.action.MAIN" />
    6. <category android:name="android.intent.category.LAUNCHER" />
    7. </intent-filter>
    8. </activity>

  • Gradle:

defaultConfig {manifestPlaceholders = [ configChanges:"orientation"]}
