我想为我的清单文件和gradle文件中的所有活动设置一个属性(android:configChanges =“ screenSize | smallestScreenSize | screenLayout”),而我尝试执行的操作如下:我在我的应用模块的build.gradle文件中添加了一些代码片段:
android.applicationVariants.all { variant ->
print("check variant:${variant.getClass()}\n")
variant.outputs.each { output ->
print("check output all task:${output.getName()}\n")
def processorTask = output.processManifestProvider.getOrNull()
print("check processorTask:${processorTask.getName()}\n")
//ProcessApplicationManifest
//https://android.googlesource.com/platform/tools/base/+/studio-master-dev/build-system/gradle-core/src/main/java/com/android/build/gradle/tasks/ProcessApplicationManifest.java
processorTask.doLast {task ->
def directory = task.getBundleManifestOutputDirectory()
def srcManifestFile = "$directory${File.separator}AndroidManifest.xml"
print("check manifest file:$srcManifestFile\n")
def manifestContent = new File(srcManifestFile).getText()
def xml = new XmlParser(false, false).parseText(manifestContent)
print("check manifest application:${xml.application.size()}")
xml.application[0].activity.forEach{
it.attributes().put('android:configChanges', 'screenSize|smallestScreenSize|screenLayout')
}
def serializeContent = groovy.xml.XmlUtil.serialize(xml)
def targetFile = new File(srcManifestFile)
targetFile.write(serializeContent)
}
}
}
执行命令gradlew assembleDebug
后,它会生成一个文件和一个apk。文件内容类似于此图
图片的内容是我所需要的,但是生成的apk文件的内容是这样的:它失去了添加在gradle任务中的属性。我想知道如何使其工作,请提供帮助。
我的环境
您可以使用清单占位符解决:
Manifest:
<activity
android:name=".YourActivity"
android:configChanges="${configChanges}">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Gradle:
defaultConfig {manifestPlaceholders = [ configChanges:"orientation"]}
几天后,我以正确的方式自行解决了此问题:
project.afterEvaluate {
def variants = null
try {
variants = android.applicationVariants
} catch (Throwable t) {
try {
variants = libraryVariants
} catch (Throwable tt) {}
}
if (variants != null) {
variants.all { variant ->
variant.outputs.each { output ->
def task = output.processManifestProvider.get()
if (task == null) {
return
}
task.doLast {
def manifestFile = new File(task.manifestOutputDirectory.get().getAsFile(),"AndroidManifest.xml")
if (manifestFile == null || !manifestFile.exists()) {
return
}
def parser = new XmlParser(false, true)
def manifest = parser.parse(manifestFile)
def app = manifest.'application'[0]
app.'activity'.each{act->
String value = act.attributes()['android:configChanges']
if (value == null) {
value = "keyboardHidden|orientation|screenSize"
} else {
String[] valueSplit = value.split("\\|")
if (!valueSplit.contains("keyboardHidden")) {
value+="|keyboardHidden"
}
if (!valueSplit.contains("orientation")) {
value+="|orientation"
}
if (!valueSplit.contains("screenSize")) {
value+="|screenSize"
}
}
act.attributes()["android:configChanges"] = value
}
manifestFile.setText(XmlUtil.serialize(manifest), "utf-8")
}
}
}
}
}
app/build.gradle
的末尾。嗯,以上方法仅适用于活动的每个要素均不包含属性android:configChanges
或会出现另一个问题的情况,我将其发布here。
