Gradle 练习之一 --- 输出项目第三方库以及本地依赖库的权限信息 |
||||
--- |
||||
|
||||
#### 前言 |
||||
|
||||
标题看起来可能有点恍惚，简单来说就是对于 app module 下面的依赖，即： |
||||
|
||||
```groovy |
||||
dependencies { |
||||
// 第三方库 |
||||
implementation 'com.android.support:appcompat-v7:28.0.0' |
||||
// 本地依赖库 |
||||
implementation project(":mylibrary") |
||||
} |
||||
``` |
||||
|
||||
获取它们的 Manifest 文件里面的权限信息。 |
||||
|
||||
输出结果示例： |
||||
|
||||
```groovy |
||||
/** |
||||
* Path: /Users/omooo/AndroidStudioProjects/Projects/MyApplication/app/src/main/AndroidManifest.xml |
||||
* ModuleName: app |
||||
* |
||||
* <uses-permission android:name="android.permission.INTERNET" /> |
||||
* <uses-permission android:name="android.permission.CALL_PHONE" /> |
||||
* <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> |
||||
* <uses-permission android:name="android.permission.RECEIVE_SMS" /> |
||||
*/ |
||||
|
||||
|
||||
/** |
||||
* Path: /Users/omooo/AndroidStudioProjects/Projects/MyApplication/mylibrary/src/main/AndroidManifest.xml |
||||
* ModuleName: mylibrary |
||||
* |
||||
* <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> |
||||
* <uses-permission android:name="android.permission.INTERNET" /> |
||||
*/ |
||||
|
||||
``` |
||||
|
||||
#### 入门 |
||||
|
||||
较早之前，我们 App 因为私自获取用户敏感权限被警告了。组长就让我看看能不能获取每个 module 的权限信息，然后格式化输出。当时心想还不是简单的一批，终于到了秀操作的时候了。 |
||||
|
||||
写一个 writePermissionToFile.gradle 脚本，放在根目录，如下： |
||||
|
||||
```groovy |
||||
import java.util.regex.Matcher |
||||
import java.util.regex.Pattern |
||||
|
||||
boolean firstWrite = true |
||||
|
||||
project.afterEvaluate { |
||||
|
||||
if (!firstWrite || !project.hasProperty('android')) return |
||||
def extension = project.android |
||||
if (extension.class.name.contains('BaseAppModuleExtension')) { |
||||
project.android.applicationVariants.all { variant -> |
||||
writeFile(variant.getCheckManifest().manifest, project.name) |
||||
} |
||||
} else if (extension.class.name.contains('LibraryExtension')) { |
||||
project.android.libraryVariants.all { variant -> |
||||
writeFile(variant.getCheckManifest().manifest, project.name) |
||||
} |
||||
} |
||||
firstWrite = false |
||||
} |
||||
|
||||
static def writeFile(File manifestFile, String moduleName) { |
||||
def fileT = new File("allPermissionOfModuleFile.txt") |
||||
if (!fileT.exists()) { |
||||
fileT.createNewFile() |
||||
} |
||||
if (fileT.getText().contains(manifestFile.path)) return |
||||
Pattern pattern = Pattern.compile("<uses-permission.+./>") |
||||
Matcher matcher = pattern.matcher(manifestFile.getText()) |
||||
String firstMatch = "" |
||||
if (!matcher.find()) { |
||||
return |
||||
} else { |
||||
firstMatch = matcher.group() |
||||
} |
||||
fileT.append("/**" + "\n") |
||||
fileT.append(" * Path: " + manifestFile.path + "\n") |
||||
fileT.append(" * ModuleName: " + moduleName + "\n") |
||||
fileT.append(" * " + "\n") |
||||
fileT.append(" * " + firstMatch + "\n") |
||||
while (matcher.find()) { |
||||
fileT.append(" * " + matcher.group() + "\n") |
||||
} |
||||
fileT.append(" */" + "\n") |
||||
fileT.append("\n") |
||||
fileT.append("\n") |
||||
} |
||||
``` |
||||
|
||||
然后在项目根目录的 build.gradle 中添加： |
||||
|
||||
```groovy |
||||
boolean enablePrintPers = true |
||||
subprojects { |
||||
if (enablePrintPers) { |
||||
apply from: '../writePermissionToFile.gradle' |
||||
} |
||||
} |
||||
``` |
||||
|
||||
同步一下，在项目根目录就会生成一个 allPermissionOfModuleFile，内容如前言所示。 |
||||
|
||||
总体来说还是很简单的，甚至你还可以拿到 merge 之后的 Manifest 文件，然后剔除指定权限，代码如下： |
||||
|
||||
```groovy |
||||
/** |
||||
* 以下注释掉的代码是个骚操作 |
||||
* 它可以在打包的时候移除掉指定的权限 |
||||
* 注意：这个时候的 manifestFile 已经是 merge 之后的了 |
||||
* 其实就是字符串替换 |
||||
*/ |
||||
variant.outputs.each { output -> |
||||
output.processResources.doFirst { pm -> |
||||
String manifestPath = output.processResources.manifestFile |
||||
def file = new File(manifestPath) |
||||
def manifestContent = file.getText() |
||||
String permission = '<uses-permission android:name="android.permission.RECEIVE_SMS" />' |
||||
manifestContent = manifestContent.replace(permission, '') |
||||
file.delete() |
||||
new File(manifestPath).write(manifestContent) |
||||
} |
||||
} |
||||
``` |
||||
|
||||
开开心心的给我们组长汇报，组长说要是能把第三方库里面的权限也一起拿了就好了。 |
||||
|
||||
我... |
||||
|
||||
#### 进阶 |
||||
|
||||
那怎么才能在 Gradle 构建的时候，拿到第三方库呢？其实拿到第三方库的下载的绝对路径就好了。 |
||||
|
||||
其实也很简单，直接在 app module 的 build.gradle 添加： |
||||
|
||||
```groovy |
||||
configurations.implementation.setCanBeResolved(true) |
||||
configurations.implementation.resolve().each { |
||||
if (it.name.endsWith(".aar")) { |
||||
println(it.name) |
||||
println(it.path) |
||||
|
||||
File aarFile = it |
||||
copy { |
||||
from zipTree(aarFile) |
||||
into getBuildDir().path + "/destAAR/" + aarFile.name |
||||
} |
||||
String manifestFilePath = getBuildDir().path + "/destAAR/" + aarFile.name + "/AndroidManifest.xml" |
||||
writeFile(new File(manifestFilePath), it.name) |
||||
} |
||||
} |
||||
``` |
||||
|
||||
这里的拿到的路径如下： |
||||
|
||||
``` |
||||
appcompat-v7-28.0.0.aar |
||||
/Users/omooo/.gradle/caches/modules-2/files-2.1/com.android.support/appcompat-v7/28.0.0/132586ec59604a86703796851a063a0ac61f697b/appcompat-v7-28.0.0.aar |
||||
constraint-layout-1.1.3.aar |
||||
/Users/omooo/.gradle/caches/modules-2/files-2.1/com.android.support.constraint/constraint-layout/1.1.3/2f88a748b5e299029c65a126bd718b2c2ac1714/constraint-layout-1.1.3.aar |
||||
support-fragment-28.0.0.aar |
||||
/Users/omooo/.gradle/caches/modules-2/files-2.1/com.android.support/support-fragment/28.0.0/f21c8a8700b30dc57cb6277ae3c4c168a94a4e81/support-fragment-28.0.0.aar |
||||
animated-vector-drawable-28.0.0.aar |
||||
``` |
||||
|
||||
可以看到，是 gradle caches 里面下载好的缓存的第三方库的绝对路径，所以也就有一个致命的问题，那就是 app module 不能有 implementation project(":mylibrary") 这种本地源码依赖的方式，不然以上代码执行到这一步就会直接挂掉。 |
||||
|
||||
```groovy |
||||
configurations.implementation.resolve().each {} |
||||
``` |
||||
|
||||
那能不能在执行这个把 implementation project(":mylibrary") 这种方式依赖的给过滤掉呢？毕竟这种方式依赖的我们在初级阶段就做好了。 |
||||
|
||||
但是很可惜，我并没找到办法。 |
||||
|
||||
#### 再进阶 |
||||
|
||||
这里就要祭出杀手锏了，来自 [@海海](https://github.com/HiWong) 大佬的思路，直接抄 Gradle 源码。 |
||||
|
||||
既然是抄源码，那就要首先在 app module 依赖一下 Gralde 源码了： |
||||
|
||||
```java |
||||
implementation 'com.android.tools.build:gradle:3.4.2' |
||||
``` |
||||
|
||||
然后在 app module 的 build.gralde 添加： |
||||
|
||||
```groovy |
||||
import com.android.build.gradle.internal.dependency.ArtifactCollectionWithExtraArtifact |
||||
import com.android.build.gradle.internal.publishing.AndroidArtifacts |
||||
import org.gradle.internal.component.local.model.OpaqueComponentArtifactIdentifier |
||||
|
||||
project.afterEvaluate { |
||||
boolean isFirst = true |
||||
project.android.applicationVariants.all { variant -> |
||||
if (!isFirst) return |
||||
ArtifactCollection manifests = variant.getVariantData().getScope().getArtifactCollection( |
||||
AndroidArtifacts.ConsumedConfigType.RUNTIME_CLASSPATH, |
||||
AndroidArtifacts.ArtifactScope.ALL, |
||||
AndroidArtifacts.ArtifactType.MANIFEST) |
||||
final Set<ResolvedArtifactResult> artifacts = manifests.getArtifacts() |
||||
|
||||
for (ResolvedArtifactResult artifact : artifacts) { |
||||
println(artifact.getFile().absolutePath) |
||||
println(getArtifactName(artifact)) |
||||
writeFile(artifact.getFile(), getArtifactName(artifact)) |
||||
} |
||||
isFirst = false |
||||
} |
||||
} |
||||
|
||||
static String getArtifactName(ResolvedArtifactResult artifact) { |
||||
ComponentIdentifier id = artifact.getId().getComponentIdentifier() |
||||
if (id instanceof ProjectComponentIdentifier) { |
||||
return ((ProjectComponentIdentifier) id).getProjectPath() |
||||
|
||||
} else if (id instanceof ModuleComponentIdentifier) { |
||||
ModuleComponentIdentifier mID = (ModuleComponentIdentifier) id |
||||
return mID.getGroup() + ":" + mID.getModule() + ":" + mID.getVersion() |
||||
|
||||
} else if (id instanceof OpaqueComponentArtifactIdentifier) { |
||||
return id.getDisplayName() |
||||
} else if (id instanceof ArtifactCollectionWithExtraArtifact.ExtraComponentIdentifier) { |
||||
return id.getDisplayName() |
||||
} else { |
||||
throw new RuntimeException("Unsupported type of ComponentIdentifier") |
||||
} |
||||
} |
||||
``` |
||||
|
||||
代码是参考 ProcessApplicationManifest 这个 Task 来写的，如果在较低版本的 Gradle 则名为 MergeTasks，看名字就知道这个 Task 是干什么的了。 |
||||
|
||||
剩下还有一个需要完善的，那就是把整个流程封装成一个 Task 就好了，这就需要涉及到动态添加依赖了，毕竟这种方法必须要依赖 Gradle 源码了。 |
